A casino bonus is extra value a site gives you for signing up or staying: free spins, bonus cash on top of a deposit, or a slice of your losses back. In Britain the useful ones are now easier to spot, because since 19 January 2026 no licensed casino can ask you to wager a bonus more than ten times. The table below ranks the eight sites we rate highest overall and shows the type of welcome offer each one runs. We describe offers by type and do not quote amounts, because amounts change monthly and the terms on the casino's own page are the only version that counts.

Scores here are our overall casino scores, not a bonus-only mark. A site with a dull welcome offer can still outrank one with a flashy deal if its withdrawals, game library and safer gambling tools are better. How the bonus feeds into that score is explained further down.
The five kinds of bonus you will meet
Almost every promotion at a UK casino is one of five things wearing a different hat. Knowing which one you are looking at tells you most of what you need before you open the terms.
No-wagering free spins
The cleanest deal going. You get a set number of spins on a named slot, and whatever they win is paid as cash you can withdraw or keep playing with. No playthrough, no conversion cap in the good versions.
Two of the brands we review have built their whole identity on this. MrQ states that none of its bonuses carry wagering requirements, and PlayOJO says the same and has done since launch. We go through both offers line by line on the MrQ bonus page and the PlayOJO bonus page. They are no longer alone. bet365 and Paddy Power, among others, currently list welcome spins with no wagering on the winnings. The phrase to look for in any terms is "winnings paid in cash".
The catch is size. No-wagering spins are usually worth a small fixed amount each, and there are fewer of them than you would get in a wagered package. We think that is a fair trade. A small prize you can keep beats a large one you probably cannot.
Deposit match bonuses
The traditional welcome offer: deposit a sum and the casino adds bonus funds on top, often with spins bundled in. It was the standard format for years and has thinned out since the cap. Of our brands, 888casino and Grosvenor are among those currently listing a match with wagering attached. Each casino review states the current offer type in its facts panel.
Bonus funds are not cash. They sit in a separate balance and convert only once you have staked the required multiple, which is now ten times at most. Under the old regime a match bonus at 35x or 40x was mostly decoration. At 10x it is a realistic proposition, though still not a free one: you are expected, on average, to lose some of it on the way through. Our wagering guide shows the arithmetic.
Free spins on deposit
Spins triggered by a first deposit or a small qualifying stake on slots. They sit between the two types above: sometimes the winnings are cash, sometimes they land as bonus funds with wagering attached. The headline rarely tells you which. The terms always do, usually in the first three lines.
Check the stake value per spin as well. A hundred spins at the minimum coin size is a smaller offer than thirty at a higher one, and some packages drip spins out over several days so that you have to log in daily to collect them. We find that annoying, and say so in reviews where it applies.
No deposit bonuses
Spins or a little bonus cash for registering, before you pay anything in. They still exist at licensed UK sites but they are scarce and modest, and you will complete full identity verification before you see one. Winnings are nearly always capped. We cover what is realistic, and what "no deposit" still asks of you, in the no deposit bonus guide.
We do not keep a list of live no deposit codes. They change too quickly to keep honest, and stale lists of expired codes are one of the least useful things on casino comparison sites.
Cashback and loyalty rewards
Rewards for existing customers rather than new ones. Cashback returns a percentage of net losses, or of every stake, over a set period. Loyalty schemes hand out spins, prize draws or perks as you play.
PlayOJO's OJOplus is the best-known example among our brands: the operator states that it pays a little money back on every bet, win or lose, as cash with no wagering. Brands with a high-street or sports heritage tend to lean on daily free-to-play games and prize wheels instead. These are harmless fun if you would be logging in anyway and a poor reason to log in if you would not.
One rule of thumb for cashback: cash is good, bonus funds less so. If the money back arrives with its own wagering requirement, it is a second bonus, not a refund.
What changed on 19 January 2026
The Gambling Commission rewrote its rules on rewards and bonuses, and two changes matter to anyone comparing offers.
Wagering is capped at ten times. Before the change, 30x to 50x was routine and the Commission's own illustration was a ten pound bonus that needed five hundred pounds of bets before any withdrawal. That same bonus now needs one hundred pounds at most. Operators are free to go lower, and the no-wagering brands already did.
Mixed-product promotions are banned. A licensed operator can no longer make you use two or more types of gambling to earn one reward. The classic "bet on the football, get casino spins" offer has gone, as has anything that needs a bingo stake to unlock slots bonus funds. The regulator's reasoning is that playing across several products is linked to a higher risk of harm, and that these offers had terms too tangled for most people to follow.
The side effects are visible already. Headline amounts have shrunk, because a huge bonus at 10x is expensive to give away. April 2026 then added a second squeeze, when Remote Gaming Duty on operators rose from 21% to 40%. Expect leaner welcome packages across the market, more no-wagering spins, and fewer existing-customer promotions than a year ago. In our view that is a market with less noise in it, and better for it.
The 10x cap applies only to casinos licensed by the Gambling Commission. If you see a bonus advertised with 35x or 50x wagering to UK players, treat it as a warning about the site, not a quirk of the offer.
How to read bonus terms in two minutes
Every offer has a "significant terms" line next to it and a full set of terms behind a link. You want five things from them.
- Wagering and what it applies to. A figure between zero and ten. Check whether the multiple applies to the bonus alone or to winnings from spins.
- Maximum win or conversion cap. Many offers limit how much bonus winnings can turn into cash. A cap is not a scandal, but a low one changes what the offer is worth, and it is the term most people miss.
- Game weighting. Slots usually count in full towards wagering. Table games and live casino often count for a fraction or nothing, and a handful of high-return slots may be excluded. If you mainly play blackjack or roulette, most slot-led bonuses are not built for you.
- Expiry. Two clocks run: how long you have to claim after registering, and how long to use the spins or finish wagering. Windows are short. Miss one and the bonus, plus anything won from it, is removed.
- Payment method exclusions. Deposits by certain e-wallets or prepaid methods are sometimes excluded from welcome offers. If you plan to pay by PayPal or phone bill, check before you deposit, not after. A debit card is rarely excluded.
Two smaller points. Some terms set a maximum bet while bonus funds are active, and breaking it can void the winnings. And online slot stakes are legally limited anyway: five pounds a spin for players aged 25 and over, two pounds for those aged 18 to 24. No bonus changes that.
How we judge a bonus
We have not claimed these offers ourselves or timed how they pay out, and we will not pretend otherwise. What we do is read the published terms for each brand and mark them against the same questions.
First, can a normal player keep what they win? Zero wagering scores highest, a full 10x on a large bonus lowest. Second, is the offer honest at a glance, with the win cap, expiry and eligible games stated up front and not buried? Third, how tight are the restrictions: excluded payment methods, a single eligible slot, spins released in daily instalments. Fourth, is there anything for you after week one, such as cashback paid in cash or a loyalty scheme that does not demand heavy play?
Size comes last. A big number in a banner tells you about the marketing budget. The terms tell you about the casino.
Bonus and general terms make up a quarter of each overall score, alongside banking, safety, games and support. For three brands we have gone further and written dedicated pages: MrQ, PlayOJO and bet365.
When the best bonus is no bonus
You can decline. If you plan to deposit a tenner and play for half an hour, a wagered bonus mostly adds conditions: a balance you cannot withdraw until the playthrough is done, a deadline, a list of games that do not count. Playing with your own cash means anything you win is yours the moment it lands.
The same goes for chasing. A reload offer that arrives by email after a losing week is an advert, and it is fine to ignore it. Every licensed site lets you set deposit limits and switch off marketing by product and channel in your account settings. Set the limit before you claim anything. If offers are pulling you back more than you would like, our safer gambling page lists the tools and the free helpline.
If bonuses are not your main concern, start with the full casino rankings, or pick by what you play: slots, live casino or the payment method you want to use.
Questions people ask
What is the maximum wagering requirement on a UK casino bonus?
Ten times. Since 19 January 2026 the Gambling Commission has capped bonus wagering at 10x for every licensed operator. Our wagering requirements guide has a worked example in pounds.
Which UK casinos have no wagering requirements?
MrQ and PlayOJO both state that they attach no wagering requirements to their bonuses, so spin winnings are paid as cash. Other sites run no-wagering promotions from time to time, so read the terms of the specific offer.
Can I still get free spins for placing a sports bet?
No. Promotions that require you to use two or more product types, such as betting on sport to unlock casino spins, were banned for licensed operators on 19 January 2026.
Do I have to take the welcome bonus?
No. Licensed sites let you deposit without opting in, and if you only plan a short session with your own money, skipping the bonus keeps things simple: no wagering, no expiry clock, no bet limits beyond the legal ones.
Are casino bonus winnings taxed in the UK?
No. Players do not pay tax on gambling winnings in the UK, whether they come from a bonus or your own stake. See our guide to gambling tax in the UK.
Why are UK casino bonuses smaller than they used to be?
Two reasons. The 10x wagering cap means operators can no longer hide the cost of a large headline bonus behind heavy playthrough, and Remote Gaming Duty rose from 21% to 40% on 1 April 2026, which leaves less margin to give away.
