Operator Data
The Gambling Commission has published data to June 2025, with the dataset collected since March 2020 showing how gambling behaviour has changed over the period.
This release compares Quarter 1 (April to June) of financial year 2025 to 2026, with Quarter 1 of 2024 to 2025, looking at how the market has changed in comparative periods over a year.
This release covers data from the largest online operators and betting premises found on Britain’s high streets.
We have updated the percentage covered of the market for online gambling and retail betting. This percentage is based on Gross Gambling Yield (GGY) from regulatory returns from the 2023 to 2024 financial year.
During the quarter a maximum stake limit for online slots games was introduced. The £5 limit for all adults went live 9 April 2025 and the £2 limit for adults aged 18 to 24 went live 21 May 2025.
Note: We encourage you to always refer to the most recent excel data document which contains updated data for the entire period. This can be found on Gambling business data on gambling to June 2025 (published August 2025).
Online gambling
The online gambling data, collected from the largest online operators, covers the months March 2020 through to June 2025.
Comparison should not be made with the industry statistics dataset, as the data set reported here may include free bets and bonuses and does not cover all operators.
Latest data, from April to June 2025, shows total online GGY increased 2 percent, compared to the same period last year, to £1.49 billion. The increase was mostly driven by slots which increased by 14 percent year-on-year.
The overall number of total bets and/or spins increased 6 percent year-on-year to 26.1 billion, a new peak for the dataset. The number of average monthly active accounts1 decreased 10 percent during the quarter, compared to the previous year, with the number of average monthly active accounts totalling 12.7 million.
Online real event betting
Online real event betting GGY decreased by 9 percent year-on-year for Quarter 1, to £570 million. The number of bets decreased 7 percent, while the average monthly active accounts decreased 16 percent compared to the same quarter last year. The decreases in this vertical are likely due to the lack of a major international football tournament this year, compared to the previous year when the men’s Euro 2024 took place between 14 June and 14 July 2024.
Online slots
Slots GGY increased 14 percent year-on-year to £745 million for this reporting period. The number of spins increased 8 percent in the quarter to 24.4 billion, representing new peaks for these 2 metrics in the dataset. The number of average monthly active accounts remained stable at 4.4 million. The number of spins per session has decreased from 139 to 129 year-on-year, whilst the GGY per session also slightly decreased from £4.01 to £3.95 in the equivalent timeframe.
A couple of operators refined their session length methodology during the quarter which impacted the number of sessions, sessions over one hour and average session length metrics.
Online safer gambling indicators
The number of online slots sessions lasting longer than an hour decreased by 9 percent year-on-year to 8.8 million. The number of total sessions increased by 16 percent in the equivalent time period to 189 million. Approximately 5 percent of all sessions lasted in excess of one hour during the quarter, compared to 6 percent the previous year. The average session length decreased by one minute to 16 minutes.
A couple of operators refined their session length methodology during the quarter which impacted the number of sessions, sessions over one hour and average session length metrics.
The total number of customer interactions in Quarter 1 increased by 53 percent year-on-year to 4.4 million, with the majority remaining automated in nature. The number of direct interactions undertaken by operators in this dataset has increased by 58 percent year-on-year. During the past year, several operators have refined their markers of harms algorithms, resulting in a higher number of interactions.

Notes
1This is the total number of times activity has taken place across all verticals; therefore, an active account may be counted more than once if they participate in more than one vertical. Additionally, a quarter-on-quarter comparison means that there is a further degree of double counting in the active accounts’ data-point. For example, if an account has been active in 2 months of the 3 months in a quarter, it will be counted twice in the total for that quarter. This is only applicable to active accounts and not any of the other data-points.
