To check if an online casino is safe in the UK, look up its Gambling Commission account number on the Commission’s public register, confirm the licence is active and the exact web address is listed, then check its enforcement record and complaint history. It takes about five minutes, and it is the same check I run before reviewing any casino on BonusBobcat.

This guide walks through each step with real examples from my own reviews, including the things that catch people out: look-alike domains, offshore sites with the same name as a UK one, and licences that quietly end.

Step 1: Find the licence details on the casino’s site

Scroll to the very bottom of the casino’s homepage. A UK-licensed casino must show the name of the company that runs it and its Gambling Commission account number, usually in a line such as “licensed and regulated by the Gambling Commission under account number 12345”. Many casinos are run by a bigger operator under a white-label deal, so the company name often isn’t the brand you know.

If you can’t find a Gambling Commission account number at all, or the footer only mentions Curaçao, Anjouan, Malta or Kahnawake, the casino is not licensed for British players. Stop there.

Step 2: Look the number up on the Gambling Commission register

Go to the Gambling Commission public register and search for the account number or company name. Never trust a “verified” badge or a link to a certificate on the casino’s own site; check the register yourself. On the business page, look for:

• Status: the remote casino licence should say Active. Surrendered, revoked or suspended means you shouldn’t play there.
• The dates: a licence with an end date has finished, even if the casino’s website is still up.

Licences do end. In October 2026, one operator behind several brands I used to cover surrendered all of its UK licences, and those brands can no longer serve British players. It’s the reason I recheck the register every time I update a review.

Step 3: Check the exact web address is on the operator’s domain list

This is the step most people skip, and it matters. Every operator lists the web addresses it is licensed to run under a “domain names” tab on its register page. The site you are on should be there, written exactly as in your browser.

A real example from my reviews: Betta Bet’s casino runs on bettabet.co.uk, which the register lists as active. A related bettabet.com site, used for tips and promotions, isn’t on the list, so the place to sign up and deposit is the .co.uk address. Look-alike domains that copy a real brand’s name or logo will never appear on the register.

Watch out for offshore sites that share a name with a UK casino. Rollbit, for example, runs a UK-licensed site at rollbit.co.uk and a separate offshore crypto casino at rollbit.com that isn’t licensed for British players. The name alone tells you nothing; the domain list does.

Step 4: Read the operator’s regulatory record

Open the “regulatory action” section on the same register page. It lists fines, settlements, warnings and licence conditions, each with a link to the Commission’s explanation. A fine doesn’t automatically make a casino unsafe, but it tells you what went wrong: failing to protect at-risk customers and anti-money-laundering failings are the most common.

For example, ProgressPlay, which runs several casinos I review, was fined £1,000,000 by the Commission in May 2025. I take a point off a casino’s licence score for every enforcement action against its operator in the last five years, and every review links to the notices.

Step 5: Confirm it’s part of GamStop and has a dispute service

Every UK-licensed casino must take part in GamStop, the national self-exclusion scheme, and must name an independent dispute service (ADR) in its terms, which you can go to if the casino won’t resolve a complaint. If a site advertises itself as “not on GamStop”, it is not UK-licensed, whatever else it says.

Step 6: Check the bonus terms against UK rules

Since 19 January 2026, UK-licensed casinos can’t set wagering requirements above 10x on bonuses. If you see 30x, 35x or 50x quoted, you are either looking at an out-of-date page or a site, or a version of a site, that isn’t operating under UK rules. I came across exactly this when an affiliate link sent me to a casino’s international landing page showing 35x wagering in euros and dollars; the UK terms on the same brand were 10x. My guide to wagering requirements explains the cap.

Step 7: See what players and review sites report

A valid licence tells you a casino is regulated, not that it treats people well. Before you deposit, check:

• Casino.guru and AskGamblers for their ratings and, more usefully, for unresolved complaints and what they’re about.
• Trustpilot, but only the profile for the licensed domain. Look-alike profiles are common, and a handful of reviews tells you very little.
• Casinomeister for warnings or rogue listings.

Look for patterns rather than single angry reviews. Withdrawals held for weeks by repeated document requests, or winnings voided under a vague term, are worth taking seriously. Every BonusBobcat review puts these sources side by side so you don’t have to do it casino by casino, and this page explains how I use them.

Red flags: when not to deposit

• No Gambling Commission account number, or a number that doesn’t match the register.
• The web address isn’t on the operator’s domain list.
• “Not on GamStop”, “no verification” or “instant withdrawal, no ID needed” in the marketing.
• Wagering above 10x on a UK offer, or bonuses quoted only in euros, dollars or crypto.
• Crypto-only deposits. None of the UK-licensed casinos I review accept cryptocurrency, and crypto-only sites are almost always offshore.
• Pressure to deposit quickly, or a support team that won’t tell you who runs the site.

Even a safe, licensed casino can be the wrong place to play if gambling has stopped being fun. Deposit limits, time-outs and GamStop are there for exactly that.

Is this online casino safe? FAQs

How do I check if an online casino is licensed in the UK?

Find the Gambling Commission account number at the bottom of the casino’s website, then search for it on the Gambling Commission’s public register. The remote casino licence should be Active and the casino’s exact web address should appear on the operator’s list of domain names.

Is an online casino safe if it is licensed?

A UK licence means the casino must verify players, protect their funds to its stated level, offer GamStop and a dispute service, and follow UK bonus rules. It doesn’t guarantee good service, so also check the operator’s enforcement record and its unresolved complaints on sites such as Casino.guru and AskGamblers.

What is the most trusted online casino in the UK?

Trust comes from an active UKGC licence, a clean enforcement record and how complaints are handled, not from size. Of the 18 casinos I review, WinoMania has the strongest record: its operator has no UKGC enforcement action in the last five years and I found no unresolved complaints against it.

Are casinos not on GamStop safe?

They are not licensed in the UK, because every UKGC-licensed casino must be part of GamStop. That means no UK player protections and no independent dispute service if something goes wrong.

What should I do if a UK casino won’t pay me?

Complain to the casino first and keep a record. If it isn’t resolved, take it to the independent dispute service named in the casino’s terms. You can also report a licensed operator to the Gambling Commission, although the Commission doesn’t resolve individual disputes.
