Annual GB Treatment and Support Survey

Annual GB Treatment and Support Survey

We commission the Annual GB Treatment and Support Survey, our main source of evidence for building up an understanding of gambling harms and the needs of people who gamble in Great Britain.  

This page outlines the reports and resources that have been produced using this dataset.

The Treatment and Support Survey has been conducted every year since 2019, by YouGov1. It uses a random a sample of 18,000 adults (aged 18+) in Great Britain, making it one of the largest surveys looking into gambling harms worldwide2.   

The main focus of the survey is to monitor the demand and usage of treatment and support for gambling harms over time. It is particularly useful at showing how rates of gambling harms vary across different groups of people and areas3.   

Annual GB Treatment and Support Survey reports

Every year, YouGov produces a main report, which sets out the key findings and trends in the latest data. The survey data is supplemented with interviews and focus groups among key audiences to provide depth to the findings and themes uncovered.    

2022 Report

- This report took a deep dive into relapse, cost of living, the stigma around gambling harm and early exposure to gambling and gambling harms.  

2021 Report - This report took a deep dive into the interactions between gambling and other health behaviours (e.g., alcohol, smoking, psychological distress). It also suggested a wider group of affected others that included children, and produced population estimates for the number experiencing problems with gambling.

Annual GB Treatment and Support Survey data tables

Since 2021, we have published the aggregated data tables for those who would like to further explore the Treatment and Support Survey data.

Local authority and parliamentary constituency heat maps

We have produced heat maps, which show how the level of gambling harms and demand for support vary across the country. These maps have been produced for all local authorities and all parliamentary constituencies in Great Britain.  

Within these maps you can search for a particular area in Great Britain, and it brings up the data for that area*, as well as an infographic on the gambling harms.

Bespoke research using the Survey data

Gambling and mental health

The Annual GB Treatment and Support Survey is a rich source of data that can be used for other research focused on specific topics to do with gambling. From time to time, we commission other organisations to carry out further research using this data.   

This report, carried out by Alma Economics, examined in detail the relationship between gambling harm severity and various aspects of a person’s mental health. The study found that there is a significant link between higher rates of gambling harms and declining mental health.

Annual GB Treatment and Support Survey methodology 

The methodology can be found within each annual report, however we have previously commissioned a report investigating how methodological differences between surveys affects the accuracy of estimates of gambling harm.

1 Most of the survey questions stay relatively consistent between years to ensure change can be measured over time, with the largest change between 2019 to 2020 (where the structure of survey and sample size was changed and has now been consistent since 2020)

2 It is worth noting that although the prevalence of “problem gambling” (denoted by a score of 8+ on the Problem Gambling Severity Index) is collected, our survey is not the source of official statistics, which will be produced by the Gambling Commission from 2024 onwards
