What BonusRated does
BonusRated is an independent UK site that rates gambling welcome offers by what they are actually worth. A casino bonus, a free bet or a bingo bonus is a headline with terms attached, and the terms decide the value: how many times you have to play it through, how much you can withdraw, how long you have, what you must deposit and by which method. We read those terms for every offer, model what a typical player keeps, and rank the offers by that number rather than the one on the banner.
Take the top of the list above. NetBet Casino’s 11 no deposit free spins + 100 free spins on deposit carries no wagering at all and is capped at £100; Grosvenor Casino’s “Deposit £20, Play with £60 + 100 Free Spins” is bigger, but the £40 bonus comes with 10x wagering on deposit plus bonus — £600 of play — before its £2,000 ceiling means anything. Both are good offers. They are good for different players, and the ratings say so: 4.9/5 and 4.8/5 for value.
We only list operators licensed by the UK Gambling Commission, we show the significant terms next to every offer, and we re-check them when an operator changes them. The ratings are ours; the offers belong to the operators.

Reading a free bet in thirty seconds
Free bets are simpler than casino bonuses and easier to misjudge. bet365’s Bet £10 Get £30 is not the biggest token on the market, but the minimum odds are 1/5, singles count and the credits can be used in pieces — which is why it is the only free bet we rate 4/5. SBK’s Bet £20 Get £60 is double the money, paid as six £10 tokens restricted to multiples and bet builders with a seven-day clock; multiples bust far more often than singles, and the qualifying bet is £20, so we rate it 3.3/5. Twice the tokens, half the value per pound staked.
Four numbers tell you most of what you need: the minimum odds on the qualifying bet, whether the stake comes back on a winner, what the tokens can be used on, and how long they last. Our free bet rankings put those next to every offer so you can compare them without opening four sets of terms.

How we rate a bonus
Six things, weighted. Wagering ease counts most, because 10x on deposit plus bonus is a very different thing from 10x on the bonus alone, and none at all beats both. Then the potential win — the cap on what the offer can pay — and the real value after the playthrough, modelled at a typical slot return. The deposit required, the clarity of the terms and the time you get to clear it make up the rest. That bonus rating is then combined with the operator itself — games, user experience, trust and payout speed — into the overall score on every listing.
The weighting is why a small offer can outrank a large one. Mecca Bingo turns a £5 spend into a £20 bingo bonus at 5x, or 50 wager-free spins — 4.3/5. Kitty Bingo gives more, £35 for a £10 spend, but at 6x with the spins now wagered 10x — 3.8/5. Betfred Casino’s 200 free spins pay cash, yet the £30 cap keeps it at 4.3/5, while Casushi Casino’s 40 cash spins with no stated cap sit close behind at 3.8/5.
The full method, with the weights, is on our how-we-rate page.
How We Analyse Bonuses
We don’t rate brands — we rate bonus value. Using probability modelling, we estimate what you’ll actually walk away with after terms and wagering.
- Probability Modelling — We simulate realistic play scenarios using RTP, variance, and bet limits to estimate expected returns.
- Full Terms Analysis — Every bonus is reviewed against T&Cs: wagering requirements, game restrictions, max bet rules, and win caps.
- Real Cash Value — Our score reflects what you can realistically withdraw — not headline bonus amounts.

Who this is for
New customers, mostly: welcome offers are one per person, so the choice matters. If you play slots, the no-wagering and free-spins rankings show you what pays as cash. If you bet on sport, the free-bet ranking tells you which tokens are easy to turn into money and which are trapped behind accumulator rules. If you play bingo, the bingo page separates bonuses with a playthrough from tickets and spins without one. And if you just want the best value available anywhere today, the list at the top of this page is exactly that.
Gambling should be for entertainment, not income. All offers are for players aged 18 and over, and support is available at GambleAware.org.
