A law written back in 2005 was never really designed for the online casino market we have now. Online gaming in the UK has changed a lot in a pretty short time. New technology has made it easier to access, and that’s why the UK has spent the past few years bringing in new rules for both players and operators.

Why the Rules Had to Change

The Gambling Act 2005 was written at a time when online gaming was still relatively new. The market has since grown into something nobody really expected when the legislation was introduced. So the government's 2023 White Paper started a new round of reforms. Since then, rules covering slot stakes, financial checks, disputes, advertising and bonuses have changed.

Some of the changes are easy for players to spot. Online slots now have stake limits. Players aged 25 and over can stake up to £5 per spin, while the limit is £2 for players aged 18 to 24. These limits apply for all UKGC-licensed online casinos, so switching between operators won’t get you around them.

Affordability and financial risk checks are another part of the new system. Since February 2025, operators have been required to carry out checks when certain monthly deposit levels are reached. Some of the checks are automated and operators use them to look for signs that someone could be experiencing financial difficulties. But at higher levels, an operator could need more details from the player.

Casino bonuses have changed too. Wagering requirements on bonus funds are now capped at ten times the bonus amount. Before the reforms, requirements of 30x or even 50x were common. Mixed-product promotions have also been banned, meaning operators can’t combine casino offers with sports betting promotions. Bonuses are now easier for players to read and compare but if you're looking at a competitive online casino, the size of the welcome bonus isn't enough information on its own. The wagering rules and other conditions matter too.

And advertising has become stricter as well. Direct marketing requires explicit consent, and there are tighter rules around advertising during live sport.

More Protection for Players

Responsible gambling tools are standard requirements for UKGC-licensed operators. Players can set deposit or loss limits, use session time limits and receive reality check notifications while playing. There are also cooling-off periods before certain limits can be increased and self-exclusion is another standard option.

And GamStop is another important part of the market as the national self-exclusion scheme. Once someone registers, they are blocked from every UKGC-licensed online casino, sportsbook, poker site and bingo operator for a chosen period of six months, one year or five years.

Operators Are Feeling the Pressure

The new rules aren't the only thing changing the market. The cost of operating in the UK is going up as well. The Remote Gambling Duty increased from 21% to 40% in April 2026. That's a significant rise for companies already dealing with tighter compliance requirements. The extra tax has already affected how much operators are willing to spend on advertising and promotions. That could mean fewer big promotions, smaller marketing budgets and more consolidation across the industry.

There are concerns about the black market too. Industry figures have warned that these higher costs and stricter requirements could push some players towards offshore sites, which don’t fall under UKGC enforcement, GamStop or the UK’s Alternative Dispute Resolution framework.

What Players Need to Know

Checking the basics goes a long way. Check that an operator has a valid UKGC licence, understand the responsible gambling tools available to you and read the conditions attached to any promotion. The industry will probably look different again in a few years but for now, keeping up means understanding what the new rules actually mean when you're using an online gaming site.
