Introduction

Headline findings

This report contains findings from the third year (2025) of the Gambling Survey for Great Britain (GSGB).

The survey aims to collect data to enable us to further understand:

  • who participates in gambling
  • what type of gambling activities they participate in
  • experiences of and reasons for gambling
  • the consequences that gambling can have on individuals and others close to them.

This survey was conducted using a push-to-web approach, with data collected from 20,775 adults aged 18 years and older living in Great Britain. Fieldwork was carried out between January 2025 and January 2026, consisting of 4 waves running quarterly. The survey is commissioned by the Gambling Commission and carried out by the National Centre for Social Research in collaboration with the University of Glasgow. Further details about the methodology and its strengths and weaknesses, can be found in the GSGB Technical Report.

Interpretation of the data

The GSGB data outlined in this 2025 report represents the third year of the new baseline. It is a new baseline because previous data on gambling behaviours was collected using a different methodology. GSGB uses a push-to-web methodology, which differs from the survey data collection methods previously used to gather data on gambling. The strengths and weaknesses of the push-to-web approach are outlined in the GSGB Technical Report. In line with general literature on survey methodology, and the findings from Sturgis (2025) (opens in new tab) we know that a gambling focused survey like GSGB can over sample people who gamble, but the presence of an interviewer (as per previous survey methodologies) has a substantial effect on reported gambling impacts. Therefore, comparisons with surveys prior to year 1 of the GSGB (2023) should not be made.

The sample size of the GSGB was smaller in year 1 (2023) than years 2 (2024) and 3 (2025), however all surveys are sufficiently powered to enable comparison of estimates. Some of these are presented separately in the accompanying Gambling Survey for Great Britain: Trends Report 2023 to 2025 and the associated data tables.

The GSGB, like most other surveys, collects information from a sample of the population. Statistics based on surveys are therefore estimates, rather than precise figures, and are subject to a margin of error (a 95 percent confidence interval1). Generally, the larger the sample the smaller the margin of error. Consequently, the 2025 survey has a sample size of over 20,000 participants to minimise the margin of error. Throughout this report, unless specified otherwise, findings that have been included and all differences noted between subgroups are significant at the 95 percent significance level.
