About TopCasinoBonus
We rank UK casino bonuses by what they are genuinely worth — not by the biggest number on the banner.
TopCasinoBonus exists because casino bonus marketing is built around headlines, and headlines are misleading. A "200% up to £500" offer can be worth less than "100% up to £100" once you account for wagering, game weighting, max bet and expiry. We cut through that by scoring every offer on a single, published metric — expected value — so the bonus at the top of our table is the one actually worth the most to you.
What we do
We review UKGC-licensed casinos hands-on, read every word of the bonus terms, and rank offers using the formula in our methodology. We cover the bonus types that matter — no deposit, free spins, no wagering, welcome and more — and explain the rules in plain English in our guides.
How we stay independent
We earn affiliate commission when readers sign up through our links, which keeps the site free. That commission has no influence on our rankings — they are driven entirely by the expected-value formula and our hands-on testing. We only list casinos that hold a current UK Gambling Commission licence, and we publish every correction we receive.
