Chancellor Reviews Machine Games Duty Rates on Slot Machines Ahead of October Budget

UK Chancellor John Healey is weighing an increase in Machine Games Duty on slot machines as the Treasury looks for extra revenue before the October 28 budget, and observers note this review comes at a time of constrained public finances. The move follows recommendations from the Social Market Foundation think tank, which has suggested raising the duty on Category B machines from the current 20 percent to 40 percent.

Category B machines allow a maximum stake of £2 every 2.5 seconds, and these devices remain common in betting shops and adult gaming centres across the country. Data from industry monitoring shows they generate significant portions of venue revenue, while the proposed rate change would apply directly to that turnover.

Details of the Proposed Tax Adjustment

The Social Market Foundation outlined its case earlier this year for doubling the Machine Games Duty on these machines, and the Treasury has now placed the idea under active consideration. Officials are examining how such an adjustment might fit into broader fiscal planning, although no final decision has been confirmed yet. Reports indicate the review forms part of wider efforts to identify new income streams without immediate spending cuts.

Category B machines sit at the centre of the discussion because they operate under specific stake and speed limits that distinguish them from other gaming equipment. The duty itself is levied on the net takings after prizes are paid out, which means any rate increase would scale directly with operator profits from those devices.

Industry Groups Outline Potential Consequences

The Betting and Gaming Council has responded by highlighting risks of accelerated venue closures if the duty rises sharply. Representatives point to existing pressure on high street betting shops and adult gaming centres, where operating costs have climbed in recent years. They argue that higher taxation could reduce margins enough to force some locations to shut, resulting in job losses for staff who currently manage these sites.

Additional concerns raised by the council include the possibility that players might shift activity toward unlicensed operators if legal venues become less viable. Historical patterns in other jurisdictions have shown that tax-driven price increases sometimes coincide with growth in illegal markets, although the scale of any such shift in the UK remains untested at these proposed rates.

Treasury Position and Timeline

A Treasury spokesperson stated that decisions on tax measures will be announced at fiscal events, which keeps the October 28 budget as the expected point for any formal update. This approach aligns with standard practice where major rate changes are revealed alongside other revenue measures rather than through piecemeal statements. The current review therefore forms part of the preparatory work that precedes those announcements.

John Healey has not issued personal commentary on the specific proposal, and the process continues through civil service analysis of revenue projections and sector impact assessments. Those assessments typically incorporate operator data, employment figures, and compliance records before recommendations reach ministerial level.

Context Within Current Fiscal Environment

Public finances remain under pressure from multiple spending commitments, which has prompted departments to examine existing tax bases for potential adjustments. Machine Games Duty has stayed at 20 percent for Category B machines since the last major review, and inflation plus rising operational costs have altered the real value of that rate over time. The Social Market Foundation report positions the increase as a way to align the duty more closely with rates applied to other forms of gambling.

Operators have already begun modelling scenarios that assume teh higher rate takes effect after the budget. Some have indicated they would review machine deployment numbers and opening hours at marginal locations, while others note that any reduction in machine estates could affect supplier contracts and maintenance employment further along the supply chain.

Conclusion

The review of Machine Games Duty on Category B slot machines continues through September 2026, with the Betting and Gaming Council and Treasury both preparing positions ahead of the October 28 budget announcement. The Social Market Foundation proposal to move the rate from 20 percent to 40 percent remains under evaluation, and any decision will be communicated through the formal fiscal event process. Stakeholders on both sides continue to supply data that will inform the final outcome.
