How to start an online casino in the UK in 2026: licences, player protection and tax

Great Britain is one of the largest regulated online casino markets in the world and one of the most demanding. Most of what makes a UK launch hard is not the website: it is the licence, and a set of player-protection rules that the platform has to enforce on every account, deposit and spin. This guide sets out what the Gambling Commission requires in 2026, what changed recently, and what that means for the platform and the content you launch with.

The licences you need

Anyone offering casino games online to consumers in Great Britain needs a remote casino operating licence from the Gambling Commission, wherever the business is based. A licence from Malta, Curaçao or anywhere else does not cover British players.

Under licence condition 1.2.1, people in specified management offices must also hold a personal management licence: overall management, finance, compliance, marketing, gambling IT and anti-money-laundering. Small-scale operators have a partial exemption.

A gambling software licence is needed only if you manufacture, supply, install or adapt gambling software yourself. An operator that uses third-party games does not need one, but every game it offers must come from a supplier that holds one. For your content plan this is the key point: the catalogue you can launch in Great Britain is the part of a supplier’s catalogue that is licensed there.

How long licensing takes

The Commission publishes average processing times of 16 weeks for an operating licence and 8 weeks for a personal licence, for complete applications, and states that these are not guaranteed. Application and annual fees are banded by gross gambling yield; check the current bands on the Commission’s site against your own projections. In practice the licence, not the software, sets the launch date.

Player-protection rules the platform must enforce

UK rules are written into the product. Each line below is something the casino platform has to do automatically, on every account.

Limit reminders are part of the same standard: from 31 October 2025, players with a limit must be reminded to review it at least every six months, and players without one at least every twelve.

Financial risk assessments: approved, start date not set

Separately from the vulnerability checks, the Commission piloted financial risk assessments that use credit reference data from September 2024. On 7 July 2026 it approved a staged rollout. Stage 1 applies when net deposits exceed £5,000 in 24 hours for customers aged 25 and over, or £2,500 in 24 hours for under-25s. At full rollout the triggers fall to £1,000 in 24 hours or £3,000 in 90 days (25 and over) and £750 in 24 hours or £2,000 in 90 days (under 25). The start date for Stage 1 has not been announced; it is due in a later consultation response.

Tax: remote gaming duty is now 40%

Remote gaming duty rose from 21% to 40% on 1 April 2026. Under general betting duty, a new 25% rate for remote betting starts on 1 April 2027; remote bets on UK horse racing stay at 15%. For a casino business plan, duty at this level makes operating cost and conversion matter more than ever, and it is a reason to avoid running several separate systems that each need their own team.

The size of the market

The Commission’s industry statistics for April 2025 to March 2026, published on 17 September 2026, put online casino gross gambling yield at £5.7bn, of which £4.8bn came from slots. The whole online sector, including betting and bingo, produced £8.3bn, up 6.9%, out of £17.5bn for Great Britain as a whole.

Marketing rules

Since 1 October 2022 the CAP and BCAP advertising codes ban gambling ads that are likely to be of strong appeal to under-18s. For paid search, Google requires UK online casino advertisers to hold a Gambling Commission licence and apply for Google’s own gambling certification, and it tightened those certification rules again on 23 March and 26 August 2026.

What the platform and content have to cover

• GAMSTOP checks at registration and a full self-exclusion flow.
• Age-based stake limits on slots, applied per game category.
• Gross deposit limits, limit prompts and review reminders.
• A workflow for financial vulnerability checks and, later, risk assessments.
• A bonus engine that enforces the 10x wagering cap and single-product offers.
• A cashier without credit cards and without reversible withdrawals.
• Reporting that matches what the Commission and HMRC ask for.
• Games only from suppliers licensed for Great Britain, switched on per market.

Our casino platform handles accounts, limits, bonuses, cashier and reporting in one back office, and the game aggregator or casino API delivers content with availability set per market. For the UK, we confirm which studios and titles are licensed for Great Britain before a launch date is agreed. The wider European picture is on our Europe page.

The order a UK launch happens in

2. UKGC operating licence and personal management licences.
3. Platform configured for UK rules: limits, GAMSTOP, checks, bonus caps.
4. Content: only titles from suppliers licensed for Great Britain.
