Exclusive: UKGC may have misled policymakers over problem gambling survey data, report claims

Summary

A report by consultancy Regulus Partners accuses the UK Gambling Commission (UKGC) of misrepresenting the findings of a major study into the Gambling Survey for Great Britain (GSGB), potentially to justify loosening guidance on how GSGB statistics are used.

Regulus reviewed three experiments from a London School of Economics (LSE) and NatCen study funded by the Commission. The consultancy says the experiments produced mixed or damaging results for the GSGB but were instead used as the basis to remove a key warning advising against extrapolating PGSI scores to population-level estimates.

The report highlights internal emails and reviewer comments indicating experts did not think the research supported the guidance change. It also flags possible conflicts of interest — notably NatCen’s £4.5m contract renewal and LSE researchers’ subsequent outreach — and calls for an independent review and consideration by the Office for Statistics Regulation.

Key Points

Regulus Partners alleges the UKGC knowingly misrepresented LSE/NatCen experiment results to justify relaxing GSGB guidance.
Experiment 1 suggested topic salience may over-recruit gamblers, implying GSGB could overstate gambling prevalence.
Experiment 2 found telephone surveys produced lower estimates than online surveys, but Regulus says this has limited relevance to NHS in-person self-completion methods.
Experiment 3 did not support the idea that a longer activity list caused higher reported gambling rates.
Internal UKGC communications show at least one LSE researcher and internal reviewers thought the evidence did not warrant removing the warning about population-level extrapolation.
Regulus flags potential conflicts of interest (NatCen contract and LSE researcher engagement) and suggests possible breaches of the Civil Service Code and statistical practice standards.
The UKGC disputes Regulus’s critique, defending the GSGB and its guidance as developed with experts and stakeholders.

Context and relevance

This matters to policymakers, public-health researchers and the gambling industry. The GSGB has produced higher estimates of participation and problem gambling than other surveys; how those figures are interpreted affects policy, regulation and sector taxation. Regulus’s findings could influence ongoing reviews and regulatory scrutiny of GSGB methodology and the Commission’s transparency.

Why should I read this?

Because if the regulator has been spinning the evidence, the numbers used to shape policy — and the tax and compliance burden on industry — could be built on shaky ground. Quick version: this could reshape debates on problem gambling prevalence and who gets asked to foot the bill. Worth five minutes to get the gist.

Author style

Punchy — the piece flags serious governance and statistical concerns at the heart of gambling regulation. If you follow regulation, public statistics or industry tax policy, the detail matters: this isn’t just academic nitpicking, it could change how ministers and civil servants use survey data.
