Online gambling
The online gambling data, collected from the largest online operators, covers the months March 2020 through to March 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 January to March 2025, shows total online Gross Gambling Yield (GGY) increased 7 percent, compared to the same period last year, to £1.45 billion. The increase was mostly driven by slots which increased by 11 percent year-on-year.
Both the overall number of total bets and/or spins and the number of average monthly active accounts1saw increases during the quarter, with the number of average monthly active accounts totalled 13.5 million. Total bets and/or spins increased 5 percent while active accounts increased 2 percent, compared to the previous year.
Online real event betting
Online real event betting GGY increased by 5 percent year-on-year for Quarter 4, to £596 million. This increase was likely aided by bookmaker friendly results at this year’s Cheltenham festival. The number of bets decreased 1 percent, while the average monthly active accounts decreased 2 percent compared to the same quarter last year.
Online slots
Slots GGY increased 11 percent year-on-year to £689 million for this reporting period. The number of spins increased 6 percent in the quarter to 23.4 billion, while the number of average monthly active accounts increased 6 percent to 4.5 million a new peak for this dataset. The number of spins per session has decreased from 143 to 136 year-on-year, whilst the GGY per session also slightly decreased from £4.03 to £4.01 in the equivalent timeframe. It is important to note that historical data has been corrected to take account for the correct categorisation of a game, with the product moving from the casino vertical to the slots vertical.
Online safer gambling indicators
The number of online slots sessions lasting longer than an hour increased by 5 percent year-on-year to 10.1 million. The number of total sessions increased by 11 percent in the equivalent time period to 172 million, approximately 6 percent of all sessions lasted in excess of one hour during the quarter, the same as the previous year. The average session length remained consistent at 17 minutes.
The total number of customer interactions in Quarter 4 increased by 33 percent year-on-year to 3.9 million, a new peak for this dataset with the majority remaining automated in nature2. The number of direct interactions undertaken by operators in this dataset has increased by 53 percent year-on-year. Some operators refined their markers of harms algorithms in Quarter 3 2024-25, resulting in a higher number of interactions.
Offline Betting
The Commission has collected data from the largest LBOs for the months of March (pre-lockdown) and June 2020 through to March 2025.
GGY reported for Quarter 4 (January-March) decreased by 3 percent from Quarter 4 last year to £554 million, while the number of total bets and spins decreased by 5 percent to 3.1 billion.
Over the Counter (OTC)
The number of bets placed over the counter decreased 6 percent in the quarter compared to the same period last year to 129 million, while GGY remained consistent at £152 million.
Self-Service Betting Terminals (SSBT)
The number of bets placed on SSBTs increased by 2 percent year-on-year to 40.5 million. GGY decreased year-on-year by 1 percent to £125 million.
Machines sessions
Machines GGY decreased by 5 percent in Quarter 4 year-on-year to £276 million, with average spend per session slightly increasing by 3p year-on-year to £12.19. The average number of spins per machines session remained consistent year-on-year at 130 spins. This has also remained consistent for the last five quarters.
Offline safer gambling indicators
2.71 percent of machine sessions lasted more than one hour, which is a slight increase on 2.47 percent in Quarter 4 2023 to 2024.
Notes
1 This 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 two months of the three 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.
2 Some operators may have revised their algorithms.
