Licensing & safety
What a British licence obliges a casino to do.
A Gambling Commission licence is often waved about as a badge, which undersells it. It is a set of enforceable conditions covering who a site may accept, what it must check before you play, how it advertises and where your complaint goes if things sour. Here is what those conditions cover, and where they stop.
The licence follows the customer, not the company
Before 2014, an operator could serve British players from a licence granted elsewhere in Europe and stay outside the Commission's reach. The Gambling (Licensing and Advertising) Act changed that to a point-of-consumption rule: if a business takes gambling business from someone in Great Britain, or advertises to them, it needs a Gambling Commission operating licence regardless of where its offices, servers or corporate parent sit.
That is why a Malta-registered brand such as Casumo and a British bookmaker such as Ken Howells end up under the same rulebook when they take a British customer. It also means the phrase “licensed and regulated” is only meaningful if the regulator named is the Gambling Commission — a licence from somewhere else grants nothing to a player here.
Licensing runs deeper than the company. Senior people with responsibility for the operation hold personal management licences, and the studios supplying the games need their own gambling software licence. The chain from the person signing off a bonus campaign to the developer who wrote the slot is covered.
The conditions that change what you experience
Most of the Commission's requirements sit in a document called the Licence Conditions and Codes of Practice. A handful of them are visible from the customer's side of the screen, and they explain some things that otherwise look like pointless friction.
- Age and identity checks come before play, not afterAn operator must verify that you are 18 or over and confirm your identity before you can gamble or fund an account. If a site lets you play first and asks questions later, it is not following the rules.
- Every online operator must be signed up to GamStopParticipation in the national self-exclusion scheme is mandatory for remote operators. Register once and the block reaches all of them, which is what makes the scheme worth using.
- Player-protection tools have to be offeredDeposit limits and self-exclusion have to be available and easy to find, not buried three menus deep in the account settings.
- Marketing has to stay inside the advertising codesThe CAP and BCAP rules ban anything that suggests gambling solves money problems, is a route to success, or is a sensible response to boredom or stress. Terms that materially affect an offer must be shown with it.
- Bonus terms cannot be unfairFollowing work by the Competition and Markets Authority, operators had to strip out terms that let them cancel winnings arbitrarily or force you to keep playing to release your own funds. The current rules on this are covered on our bonus terms page.
- Complaints get a free, independent routeEvery licensee has to sign up to an alternative dispute resolution provider approved by the Commission, and it must cost you nothing to use.
Games are tested before they reach a lobby
Random number generators are not taken on trust. Remote gambling software has to meet the Commission's remote technical standards, and compliance is demonstrated through testing by an approved independent test house — names such as eCOGRA, Gaming Laboratories International, iTech Labs and BMM Testlabs appear repeatedly in the certification notes attached to slots.
Testing covers the statistical behaviour of the generator, whether the game pays out at the rate its rules claim, and whether the information shown to the player matches what the software actually does. It is why the return-to-player figure in a game's help panel is a documented property rather than a marketing number, and why the same certified build behaves identically at every casino carrying it.
What testing does not do is make a game favourable. A slot certified at 96% return is certified as keeping four pounds in every hundred staked over the long run. Independent testing confirms the maths is what the studio says it is — it does not change whose favour that maths runs in.
Checking a licence yourself, in about a minute
The Commission publishes a searchable register at gamblingcommission.gov.uk. Search the trading name of the site — not the parent company, which is often different — and you will get the legal name of the licensee, the account number, the licence status and the activities it covers.
Then look at the footer of the casino's own website. Licensees have to display their licence number and a link to their entry, and the two records should agree. A mismatch, a missing number, or a status showing anything other than active is a reason to stop and look more carefully.
One detail catches people out: a group can hold several licences under different legal entities, so the name on the register may not match the brand on the front page. That is normal. What matters is that the trading name you are using is listed against an active licence.
Where a complaint actually goes
Raise it with the operator first — it has eight weeks to give you a final answer. If you are not satisfied, take it free of charge to the ADR provider named in its terms; IBAS and eCOGRA handle a large share of British cases. The Gambling Commission uses complaints as intelligence about operator behaviour but does not arbitrate individual disputes, so sending it there first will not get your case resolved.
What the licence does not cover
It does not make gambling safe, profitable or advisable. The house edge on every game is intact and legal; regulation governs how a product is sold and run, not whether it favours you.
It also has no reach over sites operating without one. Anything outside the register sits outside GamStop, outside the ADR system and outside the advertising rules, whatever its own website claims about being licensed elsewhere.
And it cannot manage your spending for you. The tools exist because the rules require them, but nobody sets your deposit limit except you. The safer gambling tools page goes through what is available and how each one behaves in practice.
This page describes how licensing works in general terms and is not legal advice. Rules and codes of practice are updated periodically; the Gambling Commission's own guidance is the authoritative source. Spin Prospector is an independent comparison site funded by affiliate commission — not an operator, not a regulator, and not connected to the brands it lists.
