The 40% Remote Gaming Duty: Will UK Slot RTPs Drop?

On 1 April 2026, the UK Remote Gaming Duty rose from 21% to 40% of Gross Gaming Revenue, including bonus stakes. The tax nearly doubled overnight. The question every UK slot player should be asking: will casinos respond by lowering your RTP?

What the OBR Actually Modelled

The Office for Budget Responsibility thinks so. The OBR explicitly modelled that operators will seek to pass through around 90% of the duty increase by raising prices or reducing payouts. The Treasury's own forecasting body assumes RTP compression is part of how the policy works. This is not speculation from gambling forums. It is the government's published expectation.

The Operator Cost Picture

The financial impact on operators is severe and well-documented. Flutter — owner of Sky Betting, Paddy Power, and Betfair — flagged a $320 million EBITDA hit in 2026, rising to $540 million in 2027. Entain — owner of Ladbrokes, Coral, and bwin — guided to approximately £200 million in annualised costs and a £100 million EBITDA hit in FY26. Evoke — owner of William Hill and 888casino — expects £125 to £135 million in annualised costs, withdrew its guidance, announced around 200 William Hill shop closures and approximately 1,500 job losses, and entered takeover talks with Bally's Intralot at 50p per share on 20 April 2026. Rank Group — Grosvenor and Mecca — described the £46 million annualised impact as enough to wipe out the profitability of its UK business.

What Operators Say Publicly

Every operator's public mitigation plan includes marketing cuts, bonus rationalisation, supplier renegotiation, and headcount reduction. None explicitly name RTP reduction in their disclosures. But that does not mean it is not happening.

What Suppliers Are Saying

Supplier analytics firm Future Anthem named RTP adjustment as one of three mitigation levers operators are considering, alongside bonus restructuring and cloud-cost efficiency. This was published in December 2025 — before the new rate took effect. It is the strongest primary reference linking RGD to RTP action.

The Affiliate Claims to Treat With Caution

Several affiliate and media sources have claimed RTP cuts are already underway. Oddschecker reported in February 2026 that many online casinos have already started reducing RTP payout rates, citing Book of Dead variants dropping to 91.25% on UK sites. But the 91.25% Book of Dead tier has existed for years within Play'n GO's five-tier system and predates the RGD change entirely. Other claims of a universal drop from 96.0% to 94.2% average come from offshore promotional content targeting non-GamStop players and should not be treated as evidence.

The Honest Three-Week Assessment

Three weeks into the 40% regime, the honest assessment is this: RTP reductions are structurally expected, financially incentivised, technically trivial for operators to execute, and invisible to the UKGC's published statistics. But no UK-licensed operator has publicly disclosed a post-1 April RTP cut, and no provider has confirmed increased demand for lower-tier UK configurations.

What to Watch Next

The tracking opportunity is clear. The first fiscal period reflecting actual post-RGD deployment decisions is April to June 2026. Operator trading updates from Flutter, Entain, Evoke, and Rank are due in August 2026. UKGC operator data for that quarter will not publish until late 2026. In the meantime, independent RTP tracking — comparing deployed RTPs at UK casinos before and after 1 April — is the only way to detect whether the shift the OBR predicts is actually happening. That is what RTPTrack is building.
