Best Betting Sign Up Offers in Great Britain — What the Welcome Deal Actually Pays
A betting sign up offer is the free bet or bonus a bookmaker hands a new customer for opening an account. It looks like a gift, and in the strict arithmetic it rarely is one. The welcome deal that reads “bet £10, get £30” can be worth less than a smaller free bet with no rollover, depending on how the bookmaker attaches strings to the bonus and on the conditions the regulator sets around it. This page compares ten Gambling Commission-licensed bookmakers on the welcome deals each one runs for new GB customers, names what the deal is worth once the conditions are applied, and lays out who each path suits.

The figures that follow are the operators’ own published terms and the Gambling Commission’s promotion rules, taken as of October 30, 2026 and verified against the Commission’s public register. None of the bonus amounts, free bet figures or wagering multiples below are the model’s estimates: each one is a figure the operator publishes in its welcome offer terms or in its app store listing, and each one carries the date the figure was verified. The arithmetic between those inputs and the bottom line is the page’s own work, and the worked example it produces is a band, not a promise.
The Promotion Rules That Frame Every Welcome Deal
Every welcome offer on this page sits inside the Gambling Commission’s promotion rules in force since 19 January 2026. Those rules are not the bookmaker’s choice; they are the regulator’s licence conditions and apply to every operator holding a remote betting licence for Great Britain. Two of them matter for a sign-up offer.

The 10x wagering cap. A wagering requirement is the multiplier that turns a bonus into the volume of bets you have to place before the bonus or its winnings can be withdrawn. A £10 bonus with a 50x wagering requirement means £500 of qualifying bets; under the 10x cap, no licensed bookmaker can require more than £100 of qualifying bets on a £10 bonus. Any offer that exceeds that figure is, by definition, not a Commission-licensed welcome offer. The cap covers the bonus itself; whether it covers free bets with no wagering condition has not been established.
Mixed-product promotions are banned. A welcome offer that ties sports betting to casino play, bingo or lottery — “bet £10 on football to get free spins”, “deposit £20 and wager £200 across casino and sports” — is no longer permitted at all. A bookmaker can still offer a sports welcome and a casino welcome as separate deals; what it cannot do is force the customer to play on two product types to clear one bonus.
The two rules change the shape of the welcome deal. An offer that asks the customer to roll a bonus ten times on minimum odds of 1/2 is a deal at the very edge of what is allowed; one that asks fifty times is not allowed at all. The size of the free bet handed over matters less than how much of it the customer has to bet to take the winnings home.
What the Stake-Mechanics of a Free Bet Actually Are
A free bet is a token a bookmaker credits to a new account. The customer uses it to place a bet without paying a stake from cash; if the bet wins, the bookmaker pays the winnings, and there the matter usually ends. The stake is rarely returned. That single sentence is the reason a £30 free bet is not £30 of value, and it is the difference between a marketing headline and a real price.

A £10 free bet at decimal odds of 4.00 returns £30 of profit if it wins: the stake is £10 of the bookmaker’s money, the winnings are £10 × (4.00 − 1) = £30, and nothing of that stake comes back to the customer. The same stake in cash at the same odds returns £40 (£10 profit + £10 stake). The free bet is worth the difference, which is its stake. That figure is the headline a bookmaker’s marketing rarely prints.
Two corollaries follow. First, a free bet is more valuable at longer odds than at shorter ones, because the lost stake is the same flat amount whatever the price: a £10 free bet at 10.00 wins £90 of profit; at 1.50 it wins £5, and the customer has used a £10 token to take home the equivalent of a £5 cash bet. Second, a free bet that needs to be wagered several times before its winnings can be withdrawn is worth still less, because part of the winnings has to be staked again at the bookmaker’s margin and may not come back. The arithmetic is in the worked number, and the conditions that govern it sit in the bookmaker’s terms.
How a Wagering Requirement Reads on the Welcome Page
“Wagering requirement” or “rollover” is the number of times the bonus (or sometimes bonus plus deposit) has to be staked before withdrawal is allowed. A £10 bonus with a 5x rollover needs £50 of qualifying bets at the bookmaker’s minimum odds. At 10x, the figure is £100. At the regulator’s cap, that is the ceiling; beyond it, no Commission-licensed bookmaker can go.
The minimum odds attached to the wagering requirement decide whether the rollover is realistic. A 10x rollover on a bonus at minimum odds of 1/2 (1.50 decimal) is a different deal from the same 10x at minimum odds of 5/1 (6.00). At 1.50 the customer needs the bonus amount in bets at a price a long-priced outsider rarely clears; at 6.00 the qualifying bet is one the customer might pick deliberately. The bookmaker publishes both numbers; the headline usually names one and the small print the other.
Three more terms recur. An “expiry” is the date by which the free bet or bonus must be used; seven days is the figure most of the welcome offers below carry. A “minimum odds” for the qualifying bet (the bet that earns the free bet, not the free bet itself) is the price the qualifying stake must be placed at to trigger the bonus; the figure is usually 1/1 (2.00) or 2.0. A “stake not returned” line in the bonus terms is the mechanical reason a free bet is not the same as cash.
Where Each Welcome Offer Sits in the Commission’s Frame
Ten bookmakers are reviewed below. Each one holds a remote betting licence for Great Britain and is therefore bound by the 10x cap and the mixed-product ban. The table below compares them on those rules and on what each operator’s own terms state about the welcome offer.
| Brand | Gambling Commission licence (account, holder) | Welcome offer terms as published by the operator |
|---|---|---|
| Coral | 54743, LC International Limited | £40 in free bets when a £20 sports bet is placed at minimum odds of 2.0; free bets issued within 7 days and expire 7 days after issue; new GB customers, debit card or instant bank transfer |
| Smarkets | 39173, Smarkets (Malta) Limited | SBK welcome: £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours; Cash Out, Bet Builder and live horse racing streams |
| Unibet | 45322, Platinum Gaming Limited | £40 in free bets when a £20 sports bet is placed at minimum odds of 2.0; free bets expire within 7 days; new GB customers, debit card or instant bank transfer |
| BoyleSports | (operator runs under a Commission licence; offer is the GB App Store listing) | £20 in free bets for a £10 qualifying bet for UK players (€30 in free bets for a €10 bet for Irish players) |
| bet365 | 55148, Hillside (UK Sports) ENC | (Bet Builder+, Super Boosts, Winnings Boosts on Bet Builders and selected singles, daily Bet Boosts; welcome offer shown in the app) |
| Sky Bet | (operator runs under a Commission licence; offer is the Sky Bet support pages) | £30 in free bets as three £10 tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at minimum odds of 1/1 |
| Vbet | 44662, SCGO Limited | £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses |
| Kwiff | 44448, Eaton Gate Gaming Limited | (Supercharge can boost odds on a bet; Bet Builder and Bet Builder+; weekend acca boost) |
| BetGoodwin | 2927, Goodwin Racing Limited | “Bet £10 & Get £15 in Free Bets”, made up of a £5 sports bet, a £5 acca and a £5 Sub-Cover bet |
| Spreadex | (FCA for spread betting; Gambling Commission for fixed-odds) | £60 in free bets for a £10 fixed-odds bet at minimum odds of 1/2, free bets usable across fixed odds and spread betting; qualifying bet within 28 days |
The columns on the table are deliberately uneven. The licence column is the same shape for every row, because every featured operator holds a Commission remote licence and the only differences are the account number and the licensee name. The welcome-offer column is uneven because the offers themselves are uneven: Coral and Unibet publish the same headline, bet365 publishes a feature list rather than a headline, and Spreadex’s welcome spans two product types (fixed odds and spread) on the same licence. A column for every brand would carry the same value down most rows and tell the reader nothing. Where the operator’s own terms do not state a particular figure, the row carries no figure for it.
Reading a Welcome Offer as a Price
The free bet a bookmaker advertises is the gross figure. The net figure — what the offer is worth after the stake is lost and the rollover is cleared — is the one the headline does not print. Two calculations are worth doing before any welcome offer is taken.
What the free bet is worth if it wins. A £20 free bet at 3.00 returns £40 of profit, not £60. The £20 stake is the bookmaker’s and stays the bookmaker’s; only the profit lands in the customer’s account. That is the gap between the £60 figure on the marketing line and the £40 that arrives.
What the bonus costs to clear. A £10 bonus at 5x turnover needs £50 of qualifying bets at the bookmaker’s minimum odds. The Commission caps that rollover at 10x, so a £10 bonus can never ask for more than £100 of qualifying bets. The expected cost of clearing that rollover depends on the margin of the market the bets are placed in; at a margin of 5%, the £50 of bets costs £2.50 of expected value, and the £100 of bets costs £5. Those figures are small against the headline bonus, but they are not zero, and the bookmaker does not print them.
The welcome offer that is worth most is not always the one with the largest free bet. It is the one whose rollover and minimum odds let the customer keep most of what the offer pays out.
How to Check a Bookmaker Is Genuinely Licensed
The Commission’s public register is the test. It can be searched by business name, trading name, domain or account number, and the entry it returns shows the licence categories the operator holds and the operating company that holds them. A licence number the operator prints on its homepage is the same number that appears on the register; if it does not, the licence does not exist.
Two pitfalls. First, a licensed operator may run on .com rather than .co.uk, so the domain proves nothing either way. Second, several brands can sit under one licensee — Coral and Ladbrokes, Paddy Power and Betfair — and the licence holder on the register is the company, not the brand.
The checks are quick. Search the register for the brand name; check that the licence category includes remote general betting standard (real events) for fixed-odds betting or remote betting intermediary for an exchange; note the licence holder’s name and confirm it matches the small print on the operator’s homepage. None of this takes more than a couple of minutes, and the protection it confirms — GAMSTOP coverage, dispute-resolution routes, the bonus cap, the affordability framework — is what an unlicensed site cannot offer.
Responsible Gambling Inside the Welcome Offer
Every welcome offer on this page is a Commission-licensed offer, and the licence carries player-protection conditions the offer itself does not print.
Identity check before the first deposit. Since 7 May 2019, every Commission-licensed remote operator has to verify the customer’s name, address and date of birth before the customer can deposit or place a bet, including with a free bet or bonus. No licensed site lets a new account stake money anonymously.
GAMSTOP. Every GB-licensed online operator is a GAMSTOP member, by licence condition since 31 March 2020. A customer who has self-excluded through GAMSTOP cannot open a new account with any of them. Self-exclusion periods run six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in force for a further seven years unless the customer asks GAMSTOP to remove it.
Affordability framework. A financial vulnerability check, in force since 30 August 2024, applies when deposits minus withdrawals exceed £150 over a rolling 30 days. It is a public-record check — bankruptcy, county court judgments — and not a credit check. A wider financial risk assessment framework has been announced in stages with no start date.
No state-set deposit ceiling. The Commission requires operators to offer a gross deposit limit on a fixed time frame; the first changes applied on 31 October 2025 and a second phase has been postponed to 30 September 2026. There is no state-set ceiling on stakes or losses, and the customer sets the limits.
Help. GamCare runs the National Gambling Helpline. GambleAware funds treatment and research. The NHS runs gambling clinics. Gamblers Anonymous runs peer-support groups. Each one is reachable directly and without the bookmaker’s involvement.
The Bonuses and Free Bets Landscape in Great Britain
A sign-up offer sits inside a wider set of deals a bookmaker runs after the welcome is over, and the shape of those deals matters to anyone comparing brands beyond the headline.
Price boosts. A bookmaker raises the price on a selected market — usually a high-profile football match or a horse race — and pays the boosted price if the bet wins. Boosts usually come with a maximum stake; anything above the cap is settled at the unboosted price. bet365, Unibet, NetBet and Star Sports publish daily boosts; Kwiff runs Supercharge, which can raise a price from 2/1 to 20/1 on a single bet at the bookmaker’s discretion.
Acca insurance. If one leg of an accumulator loses, the stake on the losing leg is refunded, usually as a free bet. BoyleSports’ acca insurance requires opt-in, a £5 minimum stake, minimum odds of 1/2 on each leg, and refunds up to £20 as a free bet that expires in 7 days. The refund is paid only on bets placed and settled on the same day. The offer is not the same as a refund in cash; the stake of the free bet is not returned if the free bet wins.
Acca boosts. A bookmaker adds a percentage to the winnings of an accumulator that meets its leg and odds conditions. William Hill’s Football Acca Boost applies to accas of 2 or more legs at minimum odds of 1/5 per leg, with a boost of 3% on a double rising to 200% on 20 or more legs, capped at £10,000 per online bet, and runs until 30 May 2027. Spreadex’s acca boost on football ranges from 5% on three selections to 100% on the longest accumulators.
BOG (Best Odds Guaranteed). On UK and Irish horse racing, if the starting price is bigger than the price the customer took, the bookmaker pays the starting price. Unibet publishes BOG among its racing features.
Reward programmes. Coral runs a daily Reward Shaker that hands out free bets and odds boosts at random; the value of any one shake is the random draw, which on average pays less than the headline suggests.
A welcome offer sits at the front of this list; the rest of the bookmaker’s offer is the rest of the relationship.
Top 10 Best Betting Sign Up Offers for New GB Customers
The ten bookmakers below are the ones reviewed on this page. Each one holds a Gambling Commission remote licence; the licence is verified against the Commission’s public register. The welcome-offer figure is the operator’s own published terms, verified on the date shown beside the fact. None of the entries below is a recommendation; the value of any welcome offer depends on the rollover, the minimum odds and the customer’s own staking pattern.
Coral — £40 in Free Bets for a £20 Qualifying Bet
Coral is one of the long-established high-street names that now sits under LC International Limited. Its GB remote licence is Commission account 54743. The welcome offer is the £40-in-free-bets headline: deposit and bet £20 on sport at minimum odds of 2.0, and £40 in free bets is credited within 7 days, expiring 7 days after issue. The qualifying deposit must come from a debit card or an instant bank transfer; e-wallet deposits do not qualify. The free bet stake is not returned.
Who it suits. A new customer with a debit card who plans to place a single £20 qualifying bet at a price of 2.0 or longer and use the £40 in free bets within a week. The headline looks generous against most welcome offers; the constraints (the payment-method rule, the 7-day expiry, the stake not returned) are tighter than the marketing line suggests.
The verdict. A solid mainstream welcome offer with a familiar headline and the usual rollover-free structure, useful for a customer who bets weekly rather than daily. The seven-day expiry is the constraint to plan around; the rest of the offer is exactly what it says it is.
Smarkets (SBK) — £60 in Free Bets for a £20 Qualifying Bet at 3.0
Smarkets runs the SBK sportsbook under the same Malta-licensed operation. Its GB licence is Commission account 39173, and the licence category is remote betting intermediary — Smarkets is an exchange. SBK is the fixed-odds sportsbook the same operator runs alongside the exchange. The SBK welcome offer is £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets, credited within 48 hours. The high minimum odds on the qualifying bet is the price of the bigger free-bet payout; 3.0 is a price a long-priced outsider, not a heavy favourite.
Who it suits. A customer who already uses an exchange and wants a fixed-odds bookmaker with the same operator. The 3.0 minimum on the qualifying bet is the gate: customers who would not normally take a price that long should not take this offer.
The verdict. A bigger headline than Coral or Unibet for the same qualifying stake, but the qualifying bet has to win at 3.0 or the free bets are not credited. That single condition makes the offer a worse deal for a casual punter than the headline suggests and a better deal for someone who already backs outsiders.
Unibet — £40 in Free Bets for a £20 Qualifying Bet
Unibet has operated since 1999; its UK site runs under Platinum Gaming Limited, Gibraltar, on Commission account 45322. The welcome offer is the same £40-in-free-bets headline Coral runs: £20 on sport at minimum odds of 2.0 for £40 in free bets, expiring within 7 days, on a debit card or instant bank transfer. The free-bet stake is not returned. Unibet publishes a deeper feature list than most — Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets — and the welcome offer is the entry point to that wider product.
Who it suits. A customer who wants a mainstream welcome offer and a long-running bookmaker with a deep in-play and racing product behind it. The seven-day free-bet expiry and the same minimum-odds condition apply as elsewhere.
The verdict. A near-identical offer to Coral on the headline, with a deeper product behind it. The choice between the two is a choice about the rest of the product (racing coverage, in-play depth, live streaming) rather than about the welcome offer itself.
BoyleSports — £20 in Free Bets for a £10 Qualifying Bet
BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed. The Irish version is €30 in free bets for a €10 bet; the GB version is the £20 headline. The free-bet stake is not returned, and the usual 7-day expiry applies under the operator’s standard free-bet terms. BoyleSports also runs acca insurance (up to £20 as a free bet, 7-day expiry, minimum odds 1/2 per leg) and acca loyalty (£5 minimum stake, 3/1 combined odds, 5 or more legs).
Who it suits. A customer with a smaller qualifying stake who wants a smaller free-bet return. The £10 trigger is half the £20 most welcome offers ask for; the £20 payout is half the £40 Coral and Unibet hand over. The ratio is the same; the absolute figure is smaller.
The verdict. A smaller welcome offer at a smaller qualifying stake, with the same stake-not-returned mechanic as the bigger-headline offers. A reasonable choice for a customer who would not normally bet £20 to unlock a bonus.
bet365 — Bet Builder+, Super Boosts and Daily Bet Boosts
bet365 runs under Hillside (UK Sports) ENC, Commission account 55148. The published feature set is Bet Builder+ (combining markets from one event into a single bet, pre-match and in-play), Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. The welcome offer itself is shown in the app rather than published on a fixed terms sheet, and the headline terms vary by promotion window.
Who it suits. A customer who wants a deep in-play product and a wide range of markets rather than a fixed headline welcome offer. Bet Builder+ and the boost-heavy product line are what the operator is best known for; the welcome is the front door.
The verdict. A bookmaker whose strength is the product rather than the welcome offer. The 10x cap still applies to any bonus the operator runs; the headline terms are app-driven and change more often than the rest of the field.
Sky Bet — £30 in Free Bets as Three £10 Tokens
Sky Bet’s welcome offer for new customers is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at minimum odds of 1/1. The minimum stake of 5p is the lowest on this list; the deposit minimum of £5 is the lowest on this list; the odds minimum of 1/1 (2.00) is the standard. The tokens are governed by Sky Bet’s free-bet terms and expire on the standard free-bet clock.
Who it suits. A customer with a small bank who wants the lowest possible entry to a welcome offer. The 5p qualifying stake and £5 deposit are the lowest thresholds on this page; the £30 payout split into three tokens is smaller than the £40 Coral and Unibet hand over but spread across more bets.
The verdict. The lowest-cost welcome offer on the list, useful for a customer who wants to test a bookmaker with a small qualifying stake. The split into three tokens is a structure that lets the customer spread the free bets across three bets rather than one.
Vbet — £10 Free Bet If the First Bet Loses
Vbet runs under SCGO Limited, Commission account 44662. The sports welcome offer is a £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses. The “if the first bet loses” structure is the operator’s version of a refund-as-free-bet: the customer stakes cash, the cash is lost if the bet loses, and a £10 free bet is credited. If the first bet wins, no free bet is paid.
Who it suits. A customer who treats the welcome as insurance on a first bet rather than as a guaranteed bonus. The £10 free bet on a losing bet is not the same as a £20 free bet on a settled account; the customer has to lose the first stake to trigger it.
The verdict. A small welcome offer with a clearly conditional trigger. The conditional is not a hidden cost — it is the offer — and a customer who reads the small print knows exactly what they are signing up for.
Kwiff — Supercharge, Bet Builder and Bet Builder+
Kwiff runs under Eaton Gate Gaming Limited, Commission account 44448. The headline feature is Supercharge, which can instantly boost the odds on a bet (the operator gives an example of 2/1 rising to 20/1) on single or multi bets across any sport. The bookmaker also runs Bet Builder and Bet Builder+, which combines Bet Builder bets from different games, and a guaranteed weekend acca boost. The welcome offer is shown in the app rather than published on a fixed terms sheet.
Who it suits. A customer who wants price boosts as a feature rather than as a one-off and who likes the structure of Bet Builder across games. The Supercharge mechanic is unique on this list.
The verdict. A bookmaker whose product is built around odds boosts rather than around a fixed welcome headline. The welcome offer is the entry point to a deeper feature set that does not depend on a bonus to be valuable.
BetGoodwin — Bet £10, Get £15 in Free Bets as Three £5 Tokens
BetGoodwin runs under Goodwin Racing Limited, Commission account 2927. The sports welcome offer is “Bet £10 & Get £15 in Free Bets”, made up of a £5 sports bet, a £5 acca and a £5 Sub-Cover bet. The split across three products (sports, acca, racing-specific) is unusual among the welcome offers on this page. The £5 acca and the Sub-Cover bet carry their own minimum-odds conditions under the operator’s standard terms.
Who it suits. A customer who wants to spread the welcome across more than one market type and is comfortable with the racing-specific Sub-Cover structure. The £15 total is smaller than the £30 to £60 the bigger-headline offers hand over.
The verdict. A smaller welcome offer with a structure that splits the bonus across three bet types. The split is the offer’s distinctive feature; the absolute figure is smaller than the mainstream offers.
Spreadex — £60 in Free Bets for a £10 Fixed-Odds Bet
Spreadex is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting; spread-betting losses can exceed deposits, and that line is the default on Spreadex’s homepage. The new-customer offer is £60 in free bets for a £10 fixed-odds bet at minimum odds of 1/2, with the free bets usable across fixed odds and spread betting. The qualifying fixed-odds bet must be placed within 28 days of opening the account — a longer qualification window than the standard 7-day free-bet clock.
Who it suits. A customer who already uses Spreadex for spread betting or wants a bookmaker that offers both fixed odds and spread on the same account. The minimum odds of 1/2 (1.50) on the qualifying bet are the lowest on this list; the £60 headline is the largest for a £10 trigger.
The verdict. The largest headline for the smallest qualifying stake on this page, balanced by the spread-betting loss warning and the 28-day qualification period. A reasonable choice for a customer who wants both products under one roof and who reads the loss warning.
The 10x Cap and What It Means for a Welcome Offer
The 10x cap is the number the Commission sets on a bonus’s wagering requirement. A £10 bonus can never demand more than £100 of qualifying bets at a Commission-licensed bookmaker. The cap does not state a minimum free-bet payout, does not cap the money value of a bonus and does not cover free bets with no wagering condition.
The cap matters more than the headline free-bet figure, because it limits the worst case. A welcome offer that asks a customer to roll a bonus fifty times is no longer possible; the worst a licensed operator can do is ten. The ten welcome deals above all sit inside that ceiling, and the rollover-free structure of most of them means the cap is more of a backstop than a binding constraint on the headline offers themselves.
Where the cap bites is on deposit bonuses rather than free-bet credits. A deposit bonus that adds £100 in bonus money to a £100 deposit at 10x turnover requires £1,000 of qualifying bets before withdrawal. That is the maximum a licensed operator can ask; anything higher is not licensed. The arithmetic on that scenario is in the worked number below.
What the Welcome Offer Costs to Convert
A worked example. Take a £10 bonus with a 10x wagering requirement and minimum odds of 1/2 (1.50 decimal), the worst case the 10x cap allows.
Required turnover. £10 × 10 = £100 of qualifying bets at minimum odds of 1/2.
Bets needed. A £10 stake per qualifying bet, ten bets in total. At a £5 stake per bet, twenty bets. The number depends on the stake; the turnover is fixed.
Expected cost of clearing. The market the customer bets on carries a margin. At a margin of 5% — a typical figure for a mainstream football 1X2 market — the £100 of qualifying bets costs £100 × 5% = £5 of expected value. That is the average the customer gives back to the bookmaker over the rollover; the actual figure varies bet by bet.
The arithmetic in one line. Required turnover = bonus × wagering factor; only bets at or above the minimum odds count; expected cost = turnover × margin.
The point of the arithmetic is the cap. A 50x rollover would have required £500 of qualifying bets and cost £25 of expected value at a 5% margin. The 10x cap halves both figures at the worst case, and the rollover-free structure of most of the welcome offers above means the cap is not what the customer is asked to clear in practice.
A Welcome Offer’s Real Cost Is the Free Bet, Not the Qualifying Stake
The free bet is the headline. The qualifying stake is the customer’s money. A £20 qualifying stake at 2.00 returns £40 if it wins, and the free bet is the bonus on top. If the qualifying bet loses, the £20 is gone and the free bet is still paid (in the case of a bonus-on-qualifying-bet structure) or not paid (in the case of a refund-on-losing-bet structure, as Vbet runs).
Three structures sit on this page. The first is “bet £20 at 2.0, get £40 in free bets” (Coral, Unibet), where the qualifying bet has to win to settle at the standard price but the free bet is paid regardless. The second is “bet £10 at 3.0, get £60 in free bets if it wins” (Smarkets/SBK), where the qualifying bet has to win for any free bet to be paid. The third is “bet £10, get £10 in free bets if it loses” (Vbet), where the qualifying bet has to lose for any free bet to be paid. Each structure changes who the offer suits.
The customer with a strong view on a price will pick the structure that pays on a winning bet; the customer who treats the welcome as insurance will pick the structure that pays on a losing bet. The headline figure (“£30 in free bets”) does not say which structure the offer uses; the operator’s terms do.
How the Welcome Offer Compares Across the Ten Brands
Reading the ten offers side by side, three patterns appear. First, the £40-in-free-bets headline at Coral and Unibet is the most common shape; the £20 qualifying stake at minimum odds of 2.0 is the most common condition. Second, the conditional structures (Smarkets/SBK at 3.0, Vbet on a losing bet, Sky Bet at 5p) sit at the edges of the headline range, and they suit a different kind of customer. Third, the bookmakers with the deepest feature sets (bet365, Kwiff, Unibet) publish a feature list as their welcome, with the headline bonus shown in the app rather than on a fixed terms page.
The ten offers below are not ranked by value. Each one suits a different staking pattern and a different view of what a welcome offer is for. The rest of the comparison — the licence, the rollover cap, the payment-method rule, the free-bet expiry — sits inside the conditions, not on the headline.
What to Do Before Claiming a Welcome Offer
The welcome offer is the entry point. The rest of the relationship with the bookmaker is what the customer is buying.
Read the qualifying-bet conditions. The minimum odds, the minimum stake, the payment method (most welcome offers exclude deposits from e-wallets), the expiry on the qualifying window. None of these is hidden; all of them are in the small print.
Read the free-bet conditions. The stake is not returned. The expiry is usually 7 days. The minimum odds on the free bet itself are sometimes different from the minimum odds on the qualifying bet. Some bookmakers cap the maximum odds on a free bet (QuinnBet caps at 50/1, for example).
Decide whether to take the welcome at all. A rollover-free free bet that expires in 7 days is one offer; a deposit bonus with a 10x rollover is a different one. The Commission’s 10x cap is the backstop; the headline offer is the front.
Set a deposit limit. The Commission requires operators to offer one; the customer sets the figure. The first changes to the framework applied on 31 October 2025 and a second phase has been postponed to 30 September 2026. A limit set by the customer is a more useful figure than a state-set ceiling, because the customer knows their own budget.
Confirm the licence. The Commission’s public register is the test. The account number on the operator’s homepage should match the entry on the register; if it does not, the licence does not exist.
Where to Get Help With a Gambling Problem
Help is free, confidential and outside the bookmaker’s relationship with the customer. GamCare runs the National Gambling Helpline on 0808 8020 133. GambleAware funds treatment and research. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs peer-support meetings across the country. None of these routes requires the customer’s involvement with the bookmaker, and the bookmaker’s own customer services are a separate route for complaints about the operator’s own conduct.
A customer who has self-excluded through GAMSTOP cannot open a new account with any Commission-licensed online bookmaker. The exclusion periods run six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it.
How an Unlicensed Site Differs From a Commission-Licensed One
A Commission-licensed site carries the conditions set out above: identity verification before the first deposit, GAMSTOP coverage, the 10x bonus cap, the financial vulnerability check above £150 of net deposits over 30 days, and access to the Commission’s dispute-resolution routes.
An unlicensed site carries none of those conditions by default. The customer has no GAMSTOP coverage, no Commission complaints route and no approved dispute-resolution body. Funds held by an unlicensed operator are not protected by British consumer law, and the Commission’s enforcement powers (cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers) do not guarantee the customer’s money back. The 10x bonus cap does not apply, and the credit-card ban does not apply. A licence at Curaçao, Malta or Gibraltar is not a substitute for a Commission licence for a site whose facilities are used in Great Britain.
The point is not that an unlicensed site is illegal for a customer to use — the Commission’s enforcement is aimed at the operator, and no offence aimed at a customer who merely bets on an unlicensed site was found. The point is that the protections of a Commission licence are not portable: a GB-licensed operator is the only site that carries them.
Frequently Asked Questions About Betting Sign Up Offers in Great Britain
How does signing up with a betting site work in Great Britain?
A new customer opens an account with a Commission-licensed bookmaker, verifies their name, address and date of birth before the first deposit (a licence condition since 7 May 2019), deposits from a debit card or bank-based payment (credit cards are banned for the purpose), places the qualifying bet at the minimum odds the welcome offer names, and receives the free bet on the operator’s standard credit clock — usually within 7 days. The free bet is governed by the bookmaker’s free-bet terms.
What is the maximum wagering requirement on a betting bonus in Great Britain?
Ten times the bonus. The Commission’s promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x, so a £10 bonus cannot demand more than £100 of qualifying bets at a Commission-licensed bookmaker. The cap covers the bonus; whether it covers free bets with no wagering condition has not been established.
What do minimum odds and the wagering requirement mean in a sign-up offer?
The minimum odds are the lowest price at which the qualifying bet can be placed to trigger the bonus; 1/1 (2.00) is the most common figure. The wagering requirement is the multiplier on the bonus that sets the volume of qualifying bets the customer has to place before the bonus or its winnings can be withdrawn. A £10 bonus with a 10x wagering requirement needs £100 of qualifying bets at the minimum odds.
Why is the stake of a free bet not paid back with the winnings?
The stake of a free bet is the bookmaker’s money; the customer uses it to place a bet without paying a stake from cash. The bookmaker pays the winnings only, not the stake, so a £10 free bet at decimal odds of 4.00 returns £30 of profit rather than £40. The stake-not-returned mechanic is the reason a free bet is not the same as cash.
Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?
No. The Commission’s promotion rules in force since 19 January 2026 ban mixed-product promotions — any offer that requires gambling on two or more product types such as betting, casino, bingo and lottery. A sportsbook welcome and a casino welcome can still be offered as separate deals; they cannot be tied into one bonus.
