How we rate sign-up offers
Headline numbers sell, but they don’t pay out. We rank offers on real value once the small print is in: the wagering requirement, minimum odds, minimum deposit, qualifying-bet rules and how long you have to use the reward. A £50 free bet at evens with a seven-day expiry usually beats a bigger bonus locked behind heavy wagering.
What changed for 2026
From 19 January 2026, UK bonus wagering is capped at 10× across licensed sites, so older “30×–60×” terms no longer apply — we’ve updated our listings to reflect the new cap. Sign-up offers remain restricted to new customers aged 18 or over, and all UK operators run identity and affordability checks before you can withdraw.
Frequently asked questions
What are free bets and how do they work in UK betting?
Free bets let you place a wager without staking your own money. For example, bet365 offers “Deposit £5–£10, Bet £10, Get £30 in Free Bets” with code 365GMBLR. If a free bet wins, you keep the winnings minus the free-bet stake. They’re usually credited after a qualifying bet settles and expire within a set window.
How can I claim a welcome bonus at a UK bookmaker?
Sign up, make a qualifying deposit or bet, and enter any required promo code. For example, Betfred offers “Bet £10, Get £50 in Free Bets” — wager £10 at evens (2.0)+ to qualify, with no code needed. Always complete account verification before you can withdraw.
What are bonus bets and how do they differ from free bets?
Bonus bets work like free bets but can carry specific conditions, such as minimum selections or odds. An acca-insurance offer, for instance, may refund your stake as a bonus bet if one leg lets you down, with a 7-day window to use it.
How do UK betting promo codes work?
You enter the code during registration or deposit to activate the offer. Most codes — like 365GMBLR for bet365 — opt you in without changing the value; a few genuinely release the deal. We list the exact code beside each offer and say whether it’s required or optional.
What are the wagering requirements for bonus bets?
Wagering tells you how many times you must bet the bonus before withdrawing winnings. Since 19 January 2026, UK wagering is capped at 10× across licensed sites — so a £20 bonus needs at most £200 of qualifying play, far less than older terms.
Can existing customers get free bets from UK bookmakers?
Yes. Books like Unibet and BetVictor run loyalty clubs and ongoing promotions for existing customers — BetVictor’s Loyalty Club, for example, offers up to £25 in free bets with no wagering. Welcome offers, though, are for new customers only.
Are there free bet clubs for regular bettors?
Yes. Betway’s Free Bet Club rewards customers with £10 in free bets when they place £25 on trebles or accumulators each week. Qualifying-odds rules and terms apply.
How do I find offers for big events like the Premier League?
Check the promotions sections of major books like bet365 and Ladbrokes — they run boosted odds and welcome offers around big fixtures. Our promotions and best-bets pages round up the strongest event offers in one place.
How do I use a promo code to claim an offer?
Copy the code from the offer, then paste it into the sign-up or cashier field on the operator’s site. Make sure you meet the qualifying terms — minimum odds, deposit and expiry — before placing your qualifying bet.
