Support Builds for Doubling Machine Games Duty on High-Street Casinos and Adult Gaming Centres

The Social Market Foundation released findings in late June 2026 that detail 43 percent public backing for an increase in machine games duty on adult gaming centres and casinos, and the numbers point to a potential revenue boost of between £275 million and £458 million each year on top of the existing £600 million collected from Category B £2 slot machines. The proposal would lift the current 20 percent rate to 40 percent, and it focuses squarely on physical venues that avoided the earlier rise applied to remote operators.

Polling conducted as part of the same report shows consistent levels of support across different regions, while the modelling breaks down expected yields under several growth scenarios; those figures sit alongside current collection data that already reaches £600 million annually from the same machine category. Because land-based sites escaped the remote gaming duty adjustment that took effect previously, the suggested change would bring physical and online taxation closer in line, and analysts have examined how that alignment might affect operator margins without altering player stakes directly.

Key Figures from the SMF Analysis

The report sets out the duty rise as a straightforward doubling, and the projected annual uplift ranges from £275 million at the lower end to £458 million if machine usage remains steady or grows modestly. Current receipts from Category B £2 machines stand at £600 million, so the combined total could reach between £875 million and £1.058 billion once the new rate applies. The modelling accounts for possible behavioural shifts among players, yet the central estimates remain anchored to observed play volumes recorded in recent years.

Adult gaming centres, sometimes referred to as slot sheds because of their concentration of machines, along with traditional casinos on high streets, form the primary targets. These venues operate under the existing 20 percent machine games duty, and the proposal leaves other tax streams such as betting duty or remote gaming duty untouched. Data within the report compares revenue collection before and after the remote duty increase, and it illustrates how physical sites maintained their prior rate while online platforms moved to the higher threshold.

Polling Details and Regional Breakdowns

The 43 percent support figure emerges from a nationally representative sample, and responses show modest variation by age group and location. Younger respondents registered slightly higher approval rates for the tax adjustment, while older cohorts expressed more neutral positions. The polling also captured views on revenue use, and many participants indicated a preference for directing any new funds toward public services or addiction support programmes, although the report itself does not prescribe specific spending allocations.

Researchers cross-checked the survey results against earlier attitude studies on gambling taxation, and the current numbers sit within the range recorded previously. Because the question focused explicitly on physical high-street venues, the responses isolate sentiment toward land-based operators rather than mixing them with online platforms. This separation allows direct comparison with the remote gaming duty change that occurred earlier, and it highlights differing public perceptions of the two sectors.

Policy Context and Potential Timing

References within the report connect the suggested duty increase to ongoing discussions around gambling regulation, and observers have noted possible alignment with future steps under Greater Manchester mayor Andy Burnham. No formal announcement has tied the SMF findings directly to government legislation, yet the timing of the release in June 2026 places the data in front of policymakers ahead of the July parliamentary session. The earlier remote gaming duty adjustment demonstrated how rate changes can be implemented through secondary legislation, and the same mechanism could apply here if ministers choose to proceed.

Industry responses to the report have centred on the distinction between physical and online taxation, and trade bodies have pointed out that high-street venues already face higher operating costs related to premises and staffing. The SMF document includes sensitivity analysis that tests revenue outcomes under different levels of player migration or reduced machine numbers, and it shows the £275 million to £458 million range holds across most scenarios. Those projections rely on data supplied by operators to the Gambling Commission, and the report cites those official returns as the foundation for its calculations.

Revenue Modelling and Sector Impact

Machine games duty applies to the gross profit from gaming machines, and the current 20 percent rate has remained unchanged for physical sites while remote equivalents moved higher. Doubling that rate would therefore double the proportion of gross profit collected as tax, and the additional yield estimates reflect this arithmetic applied to the £600 million baseline. The report separates adult gaming centres from larger casinos in its tables, and it indicates that the smaller venues account for the majority of Category B £2 machines in operation.

Because the proposal leaves stake limits and game rules untouched, any revenue shift would derive purely from the tax rate itself rather than from changes in player behaviour driven by new restrictions. The modelling does incorporate a modest elasticity factor to account for possible reductions in play, yet the headline figures of £275 million to £458 million represent the net additional collection after that adjustment. Government statisticians would likely refine these numbers further if legislation moves forward, and the SMF report presents its estimates as a starting point for that discussion.

Conclusion

The Social Market Foundation report supplies both polling evidence at 43 percent support and revenue projections between £275 million and £458 million annually from a doubled machine games duty on adult gaming centres and casinos. Those numbers sit against the existing £600 million collected from Category B £2 machines, and the focus remains on physical high-street sites that retained the 20 percent rate after the remote sector adjustment. The June 2026 release positions the data for consideration during the July 2026 parliamentary period, with references to potential policy interest from figures such as Andy Burnham. Further official modelling would be required before any rate change could take effect, and the current document serves as one contribution to that broader conversation.
