This week’s post

Six UK-licensed casinos, in the order of our editorial scores. We earn a commission if you sign up through our links.

Advertising disclosure: the links below are affiliate links. We don’t run these casinos and aren’t responsible for their offers, accounts, payments or terms — always read the operator’s own small print.

Grosvenor Casinos

How the shortlist works

01 Licence first

A current Gambling Commission licence is the entry requirement. No licence for GB players, no listing — there are no exceptions to this.

02 Tried, then scored

We look at each site ourselves: game range, how the lobby handles, payment options, and whether deposit limits and time-outs are easy to find.

03 Paid, and saying so

Operators pay us a commission for referrals, which can affect who appears here. It never changes what we write about them — the notes and scores are ours.

04 Kept short on purpose

A list of fifty sites helps nobody. We’d rather keep a handful we can actually keep an eye on, and swap entries when something better turns up.

Common questions

Is Casino Postbox a casino?

No. We are an independent comparison website. You cannot open an account, deposit money or place a bet here. Everything to do with playing — registration, payments, withdrawals, bonuses — happens on the operator's own site, under their terms.

How does this site make money?

Through affiliate links. If you click through to a casino and sign up, the operator may pay us a commission. This funds the site but costs you nothing extra. It also means we only list operators we have a commercial relationship with — our full Affiliate Disclosure explains this.

Are the casinos listed here licensed in the UK?

Every operator we list holds a licence from the Gambling Commission for its GB-facing site at the time we add it. Licences can change, so it's sensible to check the licence details in the footer of any casino site before you register.

What do the scores mean?

They are our own editorial view, based on things like game range, site usability, payment options and the visibility of safer gambling tools. They are opinions, not measurements, and a high score is not a recommendation to gamble.

Can you help with a complaint about a casino?

We can't, as we have no access to operator accounts or systems. Raise the issue with the casino's support team first; if it isn't resolved, you can escalate to an independent ADR provider, which every UK-licensed operator must name in its terms.

How do I block myself from gambling sites?

GAMSTOP lets you self-exclude from all UK-licensed online gambling sites for six months, one year or five years, free of charge. Bank-level blocks and blocking software such as Gamban can add another layer. Our Responsible Gambling page lists the options.

The small print, briefly. Casino Postbox is an information service only. We don’t offer gambling, process bets, accept deposits, hold player funds, manage accounts or issue bonuses. All offers shown belong to the operators and may change or be withdrawn without notice.

Gambling should be paid-for entertainment, not a way to earn money. If it stops being fun, stop — and see our responsible gambling page for free, confidential help.
