How Many People Play Online Casino Games in the UK? (2026 Statistics)

The clearest online gambling statistics come from the Gambling Commission’s Survey, which, in its most recent wave, Wave 4, found that the online gambling participation rate (in the past 4 weeks) was 37%.

Online casino games in the UK sit inside that share as a smaller slice, played by a low single-digit number of adults, yet they earn more money than any other gambling activities online. 

This guide presents the latest figures on how many people in the UK now play online casino games, who they are, and what the market is actually worth.

How Many People Play Online Casino Games in the UK Right Now?

Around 37% of adults in Great Britain gambled online in the past four weeks, according to the Gambling Commission’s latest Gambling Survey for Great Britain (Wave 4, covering September 2025 to January 2026). That points to roughly 20 million online gamblers.

However, the larger share of this number prefers lottery and sports betting. Only a low single-digit percentage of people play casino games such as slots, roulette, or blackjack.

The % was measured by counting the participation rate, aka the number of online gamblers, and not inflated metrics like gambling revenue, total gambling accounts, etc.

A single person can hold several online accounts, so account totals far outpace player totals. Similarly, gambling revenue counts total gambling spending, which, again, is not the right metric. 

Participation rates count people, and that’s the metric the UK’s Gambling Commission uses to measure the outcomes in its Gambling Surveys. 

UK Gambling Participation Numbers 

The Gambling Commission’s latest wave puts overall gambling participation at 47% of adults in the past four weeks, with 37% gambling online and 27% in person.

Once you exclude people who only bought a lottery ticket, online participation drops to 15%, showing how much of the online gambling participation rate is simply lottery play rather than casino games or sports betting.

Note: This data covers Great Britain, which includes England, Scotland, and Wales. Northern Ireland is regulated separately, so the “UK” and “GB” figures are not the same.

Online vs In-Person Gambling

Online gambling, when compared to in-person betting, is the larger channel. However, once lottery-only players are excluded, in-person gambling (17%) actually edges ahead of online gambling (15%). Most online play is buying lottery tickets digitally. 

Where Casino Games Sit Among UK’s Gambling Activities

Casino games are not the most popular gambling activity that British adults participate in online. According to the Commission’s latest survey, the top online betting products were buying a National Lottery draw ticket (25%), other charity lottery tickets online (15%), and betting on sports or racing online or via an app (10%). 

Online instant win games reached 8%. Dedicated online casino games, such as slots and table games, sit below these, played by a small share of adults but with far higher per-person spending limits.

Top 5 Casinos Worth Your Attention for UK Players

Online casino games earn more than any other gambling activity in Britain, and a huge chunk of that spending is flowing to mobile-first, crypto-friendly operators. The five casinos below are reportedly capturing the highest demand, with same-day payouts and thousands of game titles,  aimed at the regular players who drive most of the revenue. 

1. Moonbet: Best Overall Casino Site in UK with 10K+ games
2. JACK: Best No KYC Casino Site for Fast Payout
3. Ignition: Best for Crypto Poker Players
4. Mbit: Fastest Casino Experience for Slots and Live Tables
5. Bitstarz: Wide Gaming Library for Crypto Users

Who Plays Online Casino Games in the UK?

Gambling participation is highest among middle-aged adults. The Gambling Commission found that overall participation peaked at 56% among 55- to 64-year-olds, followed by 54% among 45- to 54-year-olds.

Once lottery-only players are excluded, the profile shifts younger, with 25-to 44-year-olds gambling most. On the gender front, men play casino and betting products more than women.

Which Age Groups Gamble The Most?

Lottery draws pull participation upward among older adults, which is why the 55-to-64 group tops the overall table. Strip the lottery out, and the heaviest engagement shifts to 25- to 44-year-olds, the group most comfortable playing slots and live dealer games on a phone.

The Gender Gap in the UK’s Online Gambling Market

Men gamble more than women, and the gap is widest in casino and sports betting activity. Gambling Commission data shows 52% of males gambled in the past four weeks against 45% of females. Lottery play evens out the totals, but casino games and sports betting skew clearly male.

How Much is the UK Online Casino Market Worth?

Online casinos are the biggest earners in the British gambling market. Gambling Commission industry data show that remote casinos generated £1.49 billion in gross gambling yield in a single recent quarter, accounting for around 70% of all remote casino, betting, and bingo revenue. Total industry yield reached £4.5 billion, including lotteries.

The tax figures tell the same story. HMRC’s UK Betting and Gaming Statistics report that Remote Gaming Duty, the tax on online casino-style play, raised £1,163 million in 2024 to 2025, up 13% on the year and the largest of the four gaming duties. Total betting and gaming receipts reached £1,786 million in the April to August period alone.

Remote Gaming Duty And Online Revenue

Remote Gaming Duty covers online slots, casino table games, and similar remote products. HMRC data shows it is both the largest gaming duty and the fastest-growing, rising 13% in a single year while land-based receipts grew far more slowly, the clearest signal of where the money is moving.

Online Slots As The Revenue Engine

Slots do most of the heavy lifting. Gambling Commission operator data from the largest online sites shows online slots generated £773 million in gross gambling yield in the first quarter of 2026, up 12% year-on-year, with average monthly active slot accounts rising 6% to 4.8 million. 

Slots far outpaced online sports betting, which grew just 1% over the same period. A relatively small group of regular players still generates a disproportionate share of total revenue, which is why operators invest so heavily in this category. 

How Online Casino Play Overtook the High Street

Online has become the default way to gamble in Britain. Across recent Gambling Commission waves, online participation has held steady at 37% to 38% of adults, up from 36% in late 2023, while overall gambling has remained stable at 46% to 48%. Participation is flat, but the channel and the spending have shifted decisively online.

Here is how online participation has tracked across the Gambling Commission’s comparable survey waves:

Mobile is the main driver. Most online gamblers now play on a phone rather than a desktop. The convenience has also opened the door to newer types of operators, including crypto-focused platforms such as Moonbet, Ignition, JACK, bitstarz and mbit that can run entirely on mobile and settle digital currencies to mobile crypto wallets within minutes. 

Young People and Online Casino Games in the UK

Online casino play among under-18s exists but is limited. The Gambling Commission’s Young People and Gambling 2025 survey found that 8% of 11- to 17-year-olds had gambled online in the past 12 months, including 3% who played casino games on a website. Boys were four times as likely as girls to play online casino games (4% versus 1%).

What Young People Play Online

Among young people who gamble online, around 3% placed bets on a betting website or app, 3% played casino games on a website, 2% played bingo online, and 2% bet on esports. Only 1% played National Lottery instant win games online.

Gambling On A Parent’s Account

Access usually runs through an adult. The survey found 7% of young people had used a parent’s or guardian’s account to gamble online without permission, and a further 31% had done so with permission. Account controls and device restrictions matter as much as age checks at the point of play.

Problem Gambling and Online Casino Games

Online casino games carry a higher risk profile than most gambling products. The Gambling Commission’s Gambling Survey for Great Britain estimates that 2.7% of adults score 8 or above on the Problem Gambling Severity Index, roughly 1.4 million people, with a further 3.1% at risk.

People who play online slots or casino games are around five times more likely than average to be experiencing problem gambling.

This is the flip side of the revenue numbers. The products driving growth are also those most associated with harm, which is why UK regulation has tightened around online slots, with measures ranging from slower spin speeds to affordability checks.

If you play, set deposit and time limits before you start, and treat any session as entertainment, not a way to make money.

What percentage of UK adults play online casino games?

Overall participation is highest among 55-to 64-year-olds at 56%, largely due to lottery play. For casino and betting products specifically, 25-to 44-year-olds are the most active group once lottery-only players are removed from the figures.

Is online casino play growing in the UK? 

Player numbers are stable, but spending is rising. Online participation has held around 37% to 38% for two years, while online slot profits grew 15% in the year to March 2025. Growth is coming from higher spending per player, not more players.

Final Verdict: The UK Online Casino Gambling Picture in 2026

Around 37% of adults in the UK gamble online, but only a low single-digit share plays casino games specifically, and that small group accounts for the largest share of industry revenue. Player numbers have plateaued while spending climbs, suggesting the market is maturing rather than expanding.

For anyone using these numbers, check the definition behind every statistic before comparing it to another. Participation, accounts, and revenue tell three different stories, and only together do they give an accurate view of the British online gambling market in 2026.
