The “free” in a sign-up free bet does a lot of work. What arrives as a £10 credit in a new account is, in nearly every case, a token that must be wagered at a stated minimum price, on stated markets, within a stated window — and whose original value is not paid back when it wins. Read the marketing first, then read the terms: in that order the offer always looks bigger than it is. Read the terms first, and the offer becomes a small credit with attached conditions rather than a gift.

That gap between marketing and mechanics is the topic here. Britain regulates it tightly, and the page below works through what the regulation actually does (a 10x wagering cap; a ban on tying sport bets to casino bonuses), what a sign-up offer typically looks like in cash terms (most sit between £10 and £60 in free bets), and where ten licensed bookmakers stand on the rules that cost the reader real money.

How a sign-up offer works in Britain

Every licensed bookmaker in Great Britain runs some form of welcome promotion. They look different on the page and read differently in the small print, but the moving parts underneath are the same.

A new customer registers, satisfies the identity checks the Commission requires (name, address, date of birth, verified before the first deposit), funds the account by a method the offer accepts — usually a debit card or an instant bank transfer, almost never an e-wallet or a credit card — and places a “qualifying” first bet. Qualifying means the bet meets the conditions written into the offer: a minimum stake, often £10 or £20; a minimum price, often expressed as fractional odds (1/1 means decimal 2.00, evens) and quoted as “minimum odds”; and a market the offer accepts, sometimes the whole sportsbook, sometimes the win market only or a specific accumulator form.

If the qualifying bet settles as a winner, the customer keeps the winnings and the offer is closed. If the qualifying bet loses — or settles without meeting a stated condition — the free bets are credited, usually within hours, sometimes up to a week later, and the clock starts ticking on the expiry.

Three numbers decide everything: the size of the free bet credited, the minimum price the free bet can be used at, and the number of days the credit stays in the account. Stake return on a free bet is the exception — at most UK bookmakers the stake is not paid back when a free bet wins. Where research finds it returned, it says so.

The vocabulary, in British English

A free bet is a credit. A “qualifying bet” is the bet that unlocks the credit; “settled” means the result has been decided and any returns paid; “minimum odds” is the shortest price a bet may carry and still count; “wagering requirement” is how many times the bonus or its base must be turned over before any winnings become withdrawable; “each-way” is two bets of equal stake (so the stake doubles); a “treble” is three selections, all of which must win, in one stake; an “accumulator” or “acca” is the same thing with four or more legs; “cash out” is the option to settle a bet before the event finishes, at a price the bookmaker sets. Bookmaker is “bookie” in casual use; customer is “punter”; price is the odds, quoted either as fractions (5/1) or decimals (6.00), with the conversion a/b → (a ÷ b) + 1.

What a free bet is worth when the stake is not returned

The headline figure on the offer page is the nominal credit: £10, £20, £40. The number that actually matters is what that credit returns on average when it is used at a typical price, because the stake is not coming back.

For a single free bet of nominal value F, used at decimal odds D on a market whose payout share is P (so the bookmaker’s margin is 1 − P), the expected return is:

Expected return = F × (D − 1) ÷ D × P

Take a £20 free bet at decimal odds 2.00 on a market priced evenly both sides at 1.90 / 1.90. The payout share on that market — 1 ÷ (1/1.90 + 1/1.90) — is approximately 0.95, so the margin is around 5%. Plugging in: 20 × (2.00 − 1) ÷ 2.00 × 0.95 = £9.50 expected return.

A £20 credit is therefore worth about £9.50 of expected value on a market with a 5% margin. Anywhere within roughly £8 to £11 sits a reasonable band for that scenario — the exact figure moves with the margin of the market chosen and the price the bet is taken at. A reader who places the free bet at odds well above the minimum is rewarded with more expected value; one who uses it at the shortest price allowed keeps the credit but loses the upside. Below that band, the offer is generous beyond the market; above it, the offer is paying out more than it collects on average, which a licensed operator does not normally sustain.

The same logic applies to smaller and larger credits. A £10 free bet at the same setup returns about £4.75 of expected value; a £40 free bet returns about £19.00; a £60 credit around £28.50. The mechanical relationship is linear, so the more important questions are not “how big is the credit” but “what is the minimum price”, “how long does the credit last”, and “what markets is it usable on”.

The legal frame around a UK welcome offer

The market for these offers sits inside the Gambling Act 2005, the Gambling (Licensing and Advertising) Act 2014, the Licence Conditions and Codes of Practice (LCCP) and the Commission’s Remote Technical Standards. Every brand reviewed on this page holds a remote licence from the Commission and appears on its public register; a brand that did not is not listed here, because the regime that protects the customer is the same one that licenses the offer.

Two changes from the past two years shape every welcome page in Britain today. The first is the verification regime: since 7 May 2019, name, address and date of birth are checked before a customer can deposit or place a bet, including a free bet or a bonus. Anonymous play is finished at any licensed site. The second is the financial-vulnerability check that took effect on 30 August 2024 and tightened further from 28 February 2025: once a customer’s net deposits over a rolling 30 days exceed £150, the operator runs a public-record check (bankruptcy, county court judgments), not an income or credit check, before further deposits are accepted. Announced and staged financial risk assessments sit on top of it; the Commission paper of 7 July 2026 sets a phased plan with no start date, so the affordability press shorthand does not match the law on the page.

The Commission’s promotion rules in force since 19 January 2026 do the most direct work on welcome offers. Wagering requirements on bonuses are capped at 10x — a £10 bonus at 10x needs £100 of qualifying bets; above the cap, an offer is unlawful. Whether the cap extends to free bets whose wagering is zero is not established, so this page treats it as the open question it currently is and reads each operator’s own terms in full. The second rule, more visible at the sign-up stage, forbids mixed-product promotions: an offer that requires the customer to gamble on two or more product types — a sports bet to unlock casino free spins, for example — is banned. “Free bet” on a sportsbook sitting beside “free spins” on a casino is the shape the rule closes; a free bet on its own is unaffected.

Some further frame, because it appears in the small print and in the marketing emails:

• The cap on losses is the customer’s choice, not the law’s. There is no state-set deposit ceiling for sports betting; the Commission’s deposit-limit requirements (Remote Technical Standards 12) compel operators to offer a limit on a fixed time frame — the first changes applied from 31 October 2025; a planned second phase was postponed to 30 September 2026, and whether it is in force on the day a reader reads this should be checked against the Commission’s site.
• Credit cards are banned for any gambling transaction in Great Britain since 14 April 2020, which extends to credit-card-funded payments through an e-wallet; a debit card is not a credit card and is not covered.
• The player pays no tax on betting winnings (this is general information, not tax advice; a professional gambler should ask HMRC or an adviser); General Betting Duty is the operator’s tax on gross profits, currently 15%, with a 25% remote rate applying from 1 April 2027 for remote bets.
• Spread betting on financial markets is regulated by the Financial Conduct Authority, not the Commission, and one operator on this page — Spreadex — runs both products under both regulators; losses on a spread bet can exceed the deposit, which is not the case with a fixed-odds bookmaker bet.
• In-play betting is offered widely; there is no statutory list of markets or a cap on in-play stakes, and the controls are the operator’s licence conditions and customer-protection duties.
• A bonus with a 10x wagering cap is hard to abuse at scale; a bonus that is paid as cash without rollover is generous; a free bet that returns its stake would, in industry terms, be a “real money” free bet rather than a credit, and the offer pages reviewed here almost always sit in the credit camp.

The legal frame is the floor. The marketing around a welcome offer moves well above it; the small print is what enforces it.

Safer gambling and what the rules protect

A welcome offer is built into a customer-protection regime that operators do not write and that the regulator enforces. The pieces of it that touch a new account directly are worth knowing before any free bet is used.

GAMSTOP is the national multi-operator online self-exclusion scheme, a mandatory licence condition for every online operator since 31 March 2020. Excluding periods run six months, one year, five years, or five years with auto-renewal; the minimum stays in force for a further seven years after the chosen period ends unless the customer asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; the betting shop in the high street uses a separate scheme. A self-excluded customer is blocked from deposit, from bonus, from free bet credit — opening a new account at a different brand while excluded is also blocked, because GAMSTOP is shared. It works only on licensed brands; an unlicensed site has no scheme to join and no tool to honour.

A financial vulnerability check applies once net deposits cross £150 in a rolling 30 days. The check is a public-record look-up, bankruptcy and county court judgment registers, not an affordability interview and not a credit-reference search. Announced affordability checks (sometimes called “financial risk assessments”) were set out in a Commission paper of 7 July 2026 in a phased plan with no operational start date; the checks the press calls affordability are not yet in force as a single scheme, so any offer that says “we may ask about your income” should be read against the Commission’s current communications, not against a future rule assumed to be live. Where a reader sits on the boundary — net deposits close to or just over £150 in a month — the practical effect is more friction at deposit, more friction at withdrawal, and slower access to funds than at lower spend levels.

Deposit limits are the customer’s choice and the operator’s duty to offer. The Commission requires a gross limit on a fixed time frame, and licensed operators expose it in account settings; the customer sets it, and lowering it takes effect immediately, raising it after a cooling-off period the operator defines. A loss limit operates similarly; stake limits are set by the operator and are not negotiable in the same way. None of these is a state ceiling. The state sets the floor of identity checks, the floor of GAMSTOP, and the floor of the bonus cap. The ceiling on what a customer can lose is the customer.

Help exists outside the operator. GamCare runs the National Gambling Helpline; GambleAware funds treatment and information; the NHS runs gambling clinics in several regions; Gamblers Anonymous runs local meetings. None of these is a promotion and none of them requires opening an account first.

What “licensed” actually buys the reader

A Gambling Commission remote licence comes with a defined set of obligations. Identity is verified. Deposits can be capped. Marketing is constrained — no appeal to under-18s, no prominent gambling imagery in advertisements placed where under-18s are likely to see them, and ASA/CAP code rules restricting who may appear in marketing — and the bonus cap of 10x is enforced as a licence condition. Disputes route to an approved alternative dispute resolution body; complaints to the Commission are accepted. The customer can be excluded through GAMSTOP across every licensed brand in one step.

An unlicensed brand runs on its own house rules, in a jurisdiction whose enforcement runs as far as its own courts. It has no GAMSTOP, no Commission complaints route, no ASA discipline, no ADR scheme, no 10x cap, and no £150 vulnerability trigger. Funds held by an unlicensed operator are not under the Commission’s safekeeping rules, and a British customer with a complaint has the protections of the operator’s own jurisdiction only. This is the trade the reader is making: licensed equals checks, limits, GAMSTOP and a ceiling on bonus terms, but also the verification step that requires ID before any bet, including a free bet, can be placed.

The Commission’s enforcement tools include cease-and-desist notices, search-engine referrals, working with registrars, hosts and payment providers, and court-order DNS blocking powers which the Commission is being given or has just received. None of that is an ISP-level block. Honest framing matters: a licensed site is not “the safe choice” by default, and an unlicensed site is not “illegal to use”. It is a question of who the customer’s regulator is.

Bonuses, free bets and the structure of an offer

A welcome offer can be one of four shapes, and the same shape can be dressed differently. The shape is what decides what the offer is worth; the dressing is what most marketing pages spend their words on.

A matched free bet credits a free bet whose size matches the qualifying stake (capped), and the stake is not returned when the free bet wins. “Bet £10, get £10 in free bets” is the standard form; the credit is a token, not cash, and the difference matters at settlement.

A stake-refund bet refunds the stake of the first bet when it loses, and almost always refunds it as a free bet rather than cash. “Stake-refund” is one of the most overused phrases in the trade — the bettor’s risk on the offer is the qualifying stake, the refund comes as a credit, and the winnings the credit generates become withdrawable only when the credit is settled.

A deposit bonus — common on the casino side of bookmakers, rarer as a headline sports offer — credits a cash bonus in proportion to the deposit, and the bonus carries a wagering requirement before any winnings are withdrawable. A 10x wagering cap means a £10 cash bonus needs £100 of qualifying bets; a £50 cash bonus needs £500.

A price boost raises the odds on a named market, often a specific accumulator, for new customers only. The stake is paid normally, the winnings are real money, and the offer is a one-off uplift on a price the bookmaker already offered. There is no rollover because there is no bonus.

Each of these carries different mechanics and a different ceiling. A matched free bet on a market with a 5% margin, used at minimum odds, returns around 47 to 48% of its nominal value in expected return. A stake-refund bet on the same market returns roughly the same expected value, because the structure is mathematically close to a matched free bet with the timing reversed. A price boost on an accumulator can return more or less than that depending on how heavily the odds have been inflated, and is best judged by what the same bet would pay at the unboosted price.

The conditions that decide what it costs

Five conditions show up on every welcome offer, and they decide whether the credit is worth claiming.

The minimum stake is the qualifying bet the offer requires. £5 appears on some welcome pages, £20 on more, £10 sits in the middle. A £10 minimum lowers the cost of qualifying, which matters to bettors with a small budget.

The minimum odds decide which bets count as qualifying. Minimum odds of 1/2 (decimal 1.50) is common; 1/1 (decimal 2.00) appears on several of the larger brands. The lower the minimum, the easier to qualify; the higher the minimum, the more the qualifying bet depends on a market the bettor may not have planned to back.

The expiry is the window after which an unused free bet is forfeit. Seven days is standard; 30 days appears on a minority of offers. Where the offer is several free bets split across the package, the expiry may run from the credit of each one rather than from the first day of the account.

The stake return is whether the stake of the free bet is paid back with the winnings. Most UK bookmakers do not return the stake on a free bet; the offer that does is the exception. The value calculation changes materially: a £20 free bet at odds 2.00 that does return the stake is worth twice as much in expected return as the same offer with no stake return.

The market restriction decides where the free bet can be used. Some offers restrict to single bets, or to each-way bets in horse racing, or to specific accumulators. Multiples-only free bets at minimum combined odds can be useful on a long-priced acca; they are friction on a customer who wants to back a single favourite.

A welcome offer is the combination of those five; read each one and the headline figure reads very differently.

How the ranking was built

Ten licensed bookmakers appear below. The ranking is a function of how each offer shapes up against the others, with the legal frame and the safer-gambling regime as the floor under all of them.

The comparison columns on this page are the licence register entry, the holder of the licence and the trading name, and what the operator’s own terms state on the key’s subject — that is, what research found the offer page or the customer terms page reporting. A reader who wants the exact terms on a given day reads the operator’s own page on that day; a snapshot from research is a snapshot.

The columns above are what each operator’s own published material carried at the snapshot date. Where a brand offered more than the welcome offer — Coral’s Reward Shaker, BetVictor’s regular price boosts, William Hill’s Football Acca Boost, kwiff’s Supercharge feature — those features are not named in the comparison table because they are not the key’s subject, and the table keeps a single job to do.

Swifty Sports

Swifty Sports is a remote general betting standard licence holder under Swifty Global (UK) Ltd, set up around a horse-racing core and now extending into mainstream sport. The platform exposes Best Odds Guaranteed, Cash Out on horse racing and football markets, daily price boosts, live streaming and in-play betting; the Bet Builder feature is listed as “coming soon” on the operator’s own page. A welcome offer sits behind an account in the standard fashion. The combination of Best Odds Guaranteed on racing and the cash-out and price-boost menu makes Swifty the kind of bookmaker whose value compounds on a customer who bets horse racing regularly and wants the price to drift up by the off — Best Odds Guaranteed pays the higher of the taken price and the starting price, so it is a structural feature rather than a one-off.

BetGoodwin

BetGoodwin’s welcome offer is a £15 free-bet package on a £10 qualifying bet, split across three £5 credits — a sports free bet, an acca free bet and a Sub-Cover free bet — which means the credit does not arrive as one block but as three £5 credits with their own conditions. Goodwin Racing Limited holds the licence, and the brand sits close to the horse-racing side of the market. The structure matters: a £15 credit split across three bets is three chances to find a market where the bettor has a view, rather than one big credit with a single expiry. Each credit carries its own minimum odds and its own eligible markets; the headline reads “£15 in free bets”, and the headline reads correctly only when each £5 is treated as its own offer.

Betboro

Betboro’s offer is a 100% matched free bet capped at £25, requiring a debit card deposit of at least £10 and a first bet of between £5 and £25 with at least three selections, each at 3/5 (1.60) or higher. The accumulator requirement shapes the offer: a £25 free bet usable only on a treble-or-better acca is not the same product as a £25 free bet usable on any single. Webmedia Development N.V. is the licence holder, and the brand trades across multiple jurisdictions; the UK site is the one reviewed here, on its GB licence. The minimum odds of 1.60 per leg are well below the 2.00 minimum of the larger offers, which lowers the friction to qualify — and once the free bet is credited, the eligible markets are likely to be similarly constrained, by the small print rather than the headline.

Coral

Coral’s welcome sits in the standard matched-free-bet shape — “Get £40 in Free Bets when you bet £20” — and the standard terms: qualifying bet of £20 or more at minimum odds of 2.0 (1/1), free bets issued within 7 days, expiring 7 days after issue, debit card or instant bank transfer required, opt-in for new GB customers. LC International Limited is the licence holder and the corporate group behind Coral also runs Ladbrokes and a wider portfolio, which matters when an offer is read for risk: the parent group’s licence carries obligations across brands. Coral also offers an Odds Booster on hundreds of markets, a free daily Reward Shaker, and a free-to-play Football Super Series with a £10,000 jackpot — features that sit on top of the welcome, not inside it, and that belong to the customer who stays. The £40 free bet at minimum odds of 2.00 is worth around £19 of expected return on a market with a 5% margin, before any subsequent Reward Shaker or price boost is taken.

Geoff Banks

Geoff Banks is the smallest bookmaker on this list by offer size and the most horse-racing-specific by product. GB Sports Advisors Limited holds the licence; the app publishes ante-post prices on future events and live in-play prices on what is currently running. Welcome terms are stated on the operator’s own page at the snapshot, and they are not as headline-grabbing as the £40 or £60 credits from the major brands, which is the point: this is a smaller bookmaker for a customer whose betting is closer to form study than to signing up for the welcome. A customer who wants ante-post prices on racing weeks ahead and a quieter account is the reader Geoff Banks suits; a customer looking for the biggest welcome credit is not.

Betway

Betway’s offer is £40 in free bet tokens, four credits of £10 each, on settlement of a qualifying first bet of at least £10 at minimum odds of 2.0. Debit card deposits only; minimum deposit £10; 7-day expiry. Betway Limited is the licence holder. Free bets carry 1x wagering at odds of 1.75 or higher, which means a winning free bet still needs to be rolled over once at a minimum price before the winnings become withdrawable. The 1x wagering is unusual in the welcome space — most offers are 0x wagering on free bets — and it converts part of the headline credit back into the bonus-turnover mechanic that the Commission’s cap was written to constrain. The expected return calculation above assumes zero further wagering; at 1x the figure is reduced by the cost of the turnover, which on a typical market with a 5% margin on a £10 free bet is roughly £0.50 of expected cost per credit, so £2 across the four credits. The headline still reads at the right order of magnitude, but the headline understates what the bettor has to do.

Smarkets

Smarkets trades primarily as a betting exchange under a remote betting intermediary licence held by Smarkets (Malta) Limited. The companion SBK sportsbook is the on-platform bookmaker whose welcome offer is £60 in free bets on a £20 first deposit and £20 bet at minimum odds of 3.0, credited within 48 hours. Minimum odds of 3.0 are at the upper end of the welcome space — most sit at 1/1 (2.00) or 4/5 (1.80) — and they restrict the qualifying bet to a market the customer backs at shorter prices than favourites. Cash Out, Bet Builder and live horse racing streams are advertised as platform features. The licence type matters: an exchange runs on customer-vs-customer bets under different economics, so the welcome is a sportsbook concession layered on top, and the platform sits between traditional bookmaker and exchange in terms of value at the welcome stage.

Hollywoodbets

Hollywoodbets’ offer is a stake-refund free bet — the qualifier must lose for the credit to land. New players who deposit £10 or more by card receive a free bet of up to £30 if their first qualifying accumulator (stake £10+, 3+ legs, odds of 4/1 or greater) loses; one free bet per customer; settled within 7 days. Hollywoodbets International UK Limited is the licence holder. The shape of the offer — refund the stake on a losing acca, not credit a matched free bet — runs against the more common matched-free-bet structure, and it suits a customer who already plans to back an acca at the stated price and who would rather have the insurance than the credit on a winning stake. The 4/1 minimum combined odds is the gate: a customer whose natural stake is on shorter-priced accas would need to size up the bet to qualify.

Octobet

Octobet’s offer is 50% back as a free bet up to £50 plus a £10 casino bonus on the sportsbook welcome. Octopus Game Limited is the licence holder. The mixed-product shape — sportsbook and casino bonuses side by side — would, at first sight, look like the kind of promotion the 19 January 2026 rules ban, but the structure here is opt-in for two separate offers rather than a conditional tie (the sportsbook offer does not require the customer to use the casino bonus and vice versa). Read the offer page carefully on this one: the cap of 10x applies to the casino bonus’s wagering; the sport free bet is a separate product with its own terms. A reader who only wants the sports offer is well served; a reader who wants both should read both sets of terms.

10bet

10bet advertises a 100% betting bonus up to £50 for UK sign-ups, with daily free bets and free spins layered on the offer page. Blue Star Planet Limited is the licence holder. The “100% up to £50” phrasing is closer to a casino-style deposit bonus than to a matched free bet, and the small print — minimum odds, eligible markets, wagering factor on the bonus if it converts to a cash bonus at any stage — sits on the offer page. A customer who likes a deposit bonus with rollover will find this closer to that shape than to a one-off free bet; a customer who prefers a token to wager once will read it as a smaller headline than the £40 and £60 credits elsewhere.

How the offers compare on the conditions that matter

Read across the ten offers above and three numbers do most of the work: the size of the credit, the minimum odds of the qualifying bet, and the expiry window.

The largest nominal credits sit at Spreadex (£60 for a £10 fixed-odds bet, usable across fixed odds and spread betting) and at Smarkets’ SBK (£60 for a £20 bet at minimum odds of 3.0). Coral, Unibet, Betway and Hollywoodbets cluster around £30 to £40. Swifty, BetGoodwin and Betboro sit lower in nominal terms, around £10 to £25. The headline number is not the value number, because minimum odds and expiry winnow the offers. A £60 credit at minimum odds 3.0 with a 7-day expiry is a tightly constrained product; a £15 credit split across three markets with no minimum-odds gate on the credit is a more flexible one.

Minimum odds split the list roughly in half: 1.50 (3/5), 1.60, 1.75, 1.80 and 2.00 all appear. 2.00 is the most common. A bookmaker offering minimum odds of 1/2 (1.50) is making the qualifying bet easier to place but is also more confident the customer will use the free bet on a market the bookmaker prices comfortably — the easier the qualifier, the more the offer is built around the free-bet stage rather than the qualifying stage.

Expiry sits at 7 days for almost every brand; 30 days appears on Sky Bet’s free bets in the wider research, which is the longest window in the offer space reviewed here. A long expiry does not cost the bookmaker much because unused free bets expire and become house profit; from the bettor’s side, a long expiry is a feature, not a marketing concession.

Stake return is the silent clause. Most UK bookmakers do not return the stake on a free bet, and the value calculation above assumes that is the case. Sky Bet, Betway, BetGoodwin and Hollywoodbets’ “stake returned as a free bet” wording are all written to confirm non-return in different language. Where a free bet does return the stake, the headline looks smaller than it is, and the calculation above doubles.

What a welcome offer costs the bettor to clear

A welcome offer with no wagering on the free bet costs the bettor only the qualifying bet’s expected loss at the market margin. On a market with a 5% margin, a £20 qualifying bet costs the bettor about £1 of expected value regardless of whether the bet wins or loses; the bettor either gets the free bet (and the qualifying stake back, minus a small expected loss) or collects the winnings on a winning qualifying stake and closes the offer. With a 1x wagering requirement, as on Betway, an additional expected loss at the same margin on the turnover amount applies, which is roughly half a pound per £10 of free-bet credit at the typical market.

That is the floor. The ceiling is a wagering requirement on a cash bonus, which the 10x cap bounds but does not eliminate. A £10 cash bonus at 10x on a market with a 5% margin costs the bettor about £5 of expected loss to clear, before any winnings are realised — and that £5 wipes out the headline value of a £10 bonus at 2.00 odds on the same market. A reader who reads an offer as “a £10 bonus for signing up” and does not read the wagering factor buys an offer whose value is materially below the headline.

Edge cases worth naming

A “best odds guaranteed” feature is a structural price-floor on horse racing — the bettor is paid the higher of the taken price and the starting price — and is not a welcome promotion. It appears on Swifty Sports and on Unibet among the wider research and is among the features that persist past the welcome window.

“Acca insurance” refunds the stake of a losing accumulator as a free bet, usually when one leg lets the bet down. BoyleSports Acca Insurance requires opt-in, a £5 minimum stake, 1/2 (1.50) minimum odds, pays a maximum refund of £20 as a free bet that expires in 7 days, and the bets must be placed and settled on the same day. This is a separate promotion from the welcome; it is mentioned here because it appears in the same breath as “free bet” offers in marketing, and a reader who interprets it as a welcome offer is reading the wrong line on the page.

“Acca loyalty” pays a free bet on a winning accumulator of a stated length. BoyleSports Acca Loyalty requires opt-in, a £5 minimum stake, combined odds of 3/1 (4.00) or greater, and 5 or more settled legs, with a free bet that expires after 7 days. This is a reward for repeat play rather than a welcome.

A football acca boost is a separate product again — William Hill’s Football Acca Boost, for example, adds a percentage boost to acca winnings on 2 or more legs, scaling from 3% on a double to 200% on 20 or more legs, with a maximum boost of £10,000 per online bet, running until 30 May 2027. None of these is the same product as a welcome offer, and none of them is the offer a reader signing up to claim.

A “Bet Builder” feature combines markets from one event into a single bet; “Bet Builder+” extends that across events. Both are advertised on several brands reviewed here (bet365 Bet Builder+, kwiff Bet Builder and Bet Builder+), and neither is part of the welcome offer.

A price boost — Supercharge at kwiff is the more visible version, capable of instantly boosting odds on a bet from 2/1 to 20/1 on a single bet — is a welcome-marketing touch, not the welcome itself.

A financial-spread-betting option at Spreadex widens what an offer unlocks: the £60 in free bets at Spreadex can be used across fixed-odds and spread betting. Spread-betting losses can exceed the deposit, which is a different risk profile and a different feature from a fixed-odds free bet.

Who each offer suits

A matched free bet at low minimum odds (3/5 or 4/5) and a 7-day expiry suits a bettor who plans to qualify with a small stake and use the credit on a single market they already watch. BetGoodwin and Betboro sit in this camp.

A matched free bet at minimum odds 1/1 (2.00) with a 7-day expiry suits a bettor whose qualifying bet is a single or double at short odds. Coral, Unibet, Betway sit here.

An accumulator-shaped offer — Betboro’s three-legs-each-at-1.60 minimum, Hollywoodbets’ 4/1 combined minimum acca refund — suits a bettor who already places accas regularly, because the offer’s value sits inside a product the customer is buying anyway.

A stake-refund free bet on a losing first acca (Hollywoodbets) suits a customer whose staking strategy naturally builds a small losing streak at the start and who would value the insurance over a matched credit on a winner.

A 1x-wagered free bet (Betway) suits a customer who reads the offer carefully and accepts the extra step, because the headline has more dollars per credit than a no-wagering offer once the expected cost is taken into account.

A spread-betting-friendly offer (Spreadex) suits a customer who already runs a spread-betting book and treats the welcome as a small concession layered on a different product.

The shape that does not suit anyone is the one the bettor does not read. That is the offer with a bonus paid in cash that needs clearing at a high wagering, an offer that is mixed-product-tied against the Commission’s ban, or an offer restricted to betting markets the customer does not use.

Picking the right one

Ten brands on the page is a wider choice than most customers actually want, and the columns above reduce that to three variables: nominal credit, minimum odds, expiry. From there the choice turns on what a customer already bets.

A bettor whose sport is horse racing wants Best Odds Guaranteed more than a big welcome — Swifty Sports and Unibet among the wider pool. A bettor who places accumulators regularly wants an offer that fits the acca shape (Hollywoodbets, Betboro). A bettor who backs singles and doubles at odds-on to 2/1 sits squarely in the Coral / Unibet / Betway cluster. A bettor whose first bet is a long-odds punt (a 3/1 shot, a 5/1 outsider) finds the Smarkets / SBK offer framed around them, with the higher minimum odds a feature rather than a friction.

The honest answer is that the difference between the major offers is small once minimum odds, expiry and stake-return are normalised. The expected return calculation above puts a £20 credit at odds 2.00 on a 5%-margin market at around £9.50; a £40 credit at the same setup returns around £19.00. The bigger credits offer more expected return, but not proportionally — a £40 credit is twice the headline of a £20 credit, and roughly twice the expected return. The free-bet maths is closer to linear than the marketing suggests.

The bigger question is what happens past the welcome window. Coral’s Reward Shaker, BetVictor’s regular price boosts, bet365’s Bet Builder+, Unibet’s daily Uniboosts and live streaming — these are the features that determine what a customer pays for the rest of the year. A welcome offer should not be the reason to choose a bookmaker; the rest of the product should be.

What to check before signing up

Five points on the offer page, in the order they appear.

Identity requirements. Verification (name, address, date of birth) happens before the first deposit or bet under a Commission condition in force since 7 May 2019. A reader who cannot pass verification — without a permanent address, without a British bank account — cannot complete the registration.

Payment method. Credit cards are banned. Debit cards, instant bank transfers and a handful of bank-based payment options (Apple Pay, Google Pay, Revolut Pay, TrueLayer, Earthport, Trustly) are typically accepted; e-wallets are usually excluded from qualifying for the welcome. A reader whose deposit method is an e-wallet may fund the account but not qualify the offer.

Qualifying bet. Minimum stake, minimum odds, eligible market. The smallest qualifying stake on the offers reviewed here is £5; the largest is £20. Minimum odds range from 3/5 (1.60) at the generous end to 3.0 at the strict end. Where the offer requires an accumulator shape, the constraint is on the structure as well as the price.

Free bet use. Minimum odds on the free bet (often 1/2 or 1.5), eligible markets (singles only, or any sportsbook market), stake return policy, expiry window.

Ongoing protection. Deposit limit, time-out, GAMSTOP registration — these sit in account settings and are part of the licence the operator holds. A reader who plans to set tighter limits is using the regime the regulator wrote, and the offer page is the right place to read what is on offer before that.

Common questions on free bet sign-up offers

How do you sign up to a betting site in Britain?

Pick a brand licensed by the Gambling Commission (the public register is searchable by company name, trading name or domain). Open the account with the same name and address you hold a UK bank account under, because the operator is required to verify name, address and date of birth before the first deposit or bet. Fund the account by debit card or instant bank transfer — credit cards are banned for gambling — and place the qualifying first bet at or above the offer’s minimum stake and at or above the offer’s minimum odds. The free bet is credited on settlement of the qualifier, and the clock on expiry starts then.

How do you sign up to a sportsbook specifically?

A sportsbook is the fixed-odds bookmaker product underneath an exchange (Smarkets’ SBK is the example here) or as a standalone bookmaker (Coral, Betway, the rest of the list above). The sign-up process is the same as for any other betting site — Commission licence, identity verification, debit card or bank transfer — but the welcome offer is constructed as a sportsbook credit, so the qualifying bet is a sportsbook bet rather than a back/lay wager on an exchange.

What is the maximum wagering requirement on a betting bonus in Great Britain?

The Commission’s promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x. A £10 bonus therefore needs no more than £100 of qualifying bets before any winnings are withdrawable. The cap applies to bonuses with a wagering condition; whether it extends to free bets whose wagering is zero has not been established in the published rules, and free bet credits are treated on each operator’s own terms where the figure is zero.

What do minimum odds and a wagering requirement mean in a sign-up offer?

Minimum odds are the shortest price at which a bet will count toward the offer. Wagering requirement is how many times the bonus amount (or the deposit plus bonus, where the operator defines that base) must be turned over in qualifying bets before any winnings become withdrawable. A 10x wagering on a £10 bonus at minimum odds 1.50 (1/2) needs £100 of qualifying bets at odds 1.50 or longer. The smaller the wagering factor and the lower the minimum odds, the easier the offer is to clear; the Commission’s 10x cap is the ceiling on the first of these.

Why is the stake of a free bet not paid back with the winnings?

Because that is how a free bet is valued by the operator. A free bet whose stake returned on a win would, in industry terms, be a “real money” free bet rather than a credit; the offer pages reviewed here sit in the credit camp. Mechanically, a £20 free bet at odds 2.00 with the stake returned pays £40 on a win; without stake return it pays £20. The value calculation further up this page is built around the no-stake-return assumption because that is what most operators offer.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?

No, not as a single mixed-product offer. The Commission’s rules in force since 19 January 2026 ban mixed-product promotions, defined as an offer that requires the customer to gamble on two or more product types — for example, betting and casino, or bingo and lottery. A sportsbook welcome on its own is unaffected; a sportsbook welcome where the casino bonus is a separate opt-in promotion is also unaffected. The rule is about conditional tying, not about offering two products on the same page.
