UK Online Casinos, Compared Side by Side

Every genuinely UK-licensed casino must display its Gambling Commission licence details in the site footer, usually with a licence number that links through to the operator's public entry on the Commission's own register. A quick way to confirm is to search that register directly rather than trusting a badge on the page, since logos can be copied. Look also for 18+ marks, GAMSTOP participation and links to BeGambleAware. Every operator on our casino list is checked against the register before it appears, and the criteria are set out on our how we test page.

Rankings are built from a weighted score across fixed criteria: payout speed, game range and live casino, bonus and wagering fairness, mobile experience, banking options, and safer-gambling tools, with licensing treated as a pass-or-fail gate. Each factor carries a set weight, and the same scoring is applied to every brand, so a higher rank reflects a better result against those measures rather than a commercial deal. Operators cannot buy a position or pay to move up the table. The full methodology, including how we test withdrawals and read bonus terms, is published openly on our how we test page.

Yes. The demo slots and table games run in fun mode with virtual credits, so there is nothing to deposit, no account required and no real money at stake. They are provided so players can try a title's features, volatility and pace before deciding whether to play for real elsewhere. Because no wager is placed, any wins or losses in a demo are purely notional and cannot be withdrawn. It is a genuinely no-risk way to learn a game. Browse the collection on our free games page, and note that real-money play always carries risk.

RTP, or return to player, is the percentage of all staked money a game is designed to pay back over a very large number of spins or hands. A slot listed at 96% will, in theory, return £96 for every £100 staked across its lifetime, with the remaining 4% the house edge. It is a long-run average, not a promise for any single session, and short-term results swing widely either way. Higher RTP means better value over time, which is why we note it where operators publish it. You can compare titles and their RTP ranges on our slots page.

Since April 2020 the Gambling Commission has banned gambling with credit cards across Great Britain, online and in person, after evidence linked credit gambling to greater harm. The rule reaches through e-wallets too, so a wallet balance spent at a casino cannot be topped up from a credit card. In practice this means depositing with a debit card, a bank transfer or funds you already hold. It is a national safeguard designed to stop people gambling with borrowed money. For method-by-method detail, including debit cards and open banking, see our payment methods hub.

GAMSTOP is the free national self-exclusion scheme that lets you block yourself from all UK-licensed online casinos and betting sites at once, for a period you choose of six months, one year or five years. Every licensed operator must be signed up, so one registration covers the fleet. Alongside it, casinos offer deposit limits, time-outs and reality-check reminders you can set yourself. If gambling is causing you worry, free and confidential support is available from BeGambleAware.org and from GamCare on 0808 8020 133. Our responsible gambling page explains all of these tools and how to use them.
