UK Energy Bills to Rise 4% in October as Government Bets on VAT Cut Over Broad Support

UK energy regulator Ofgem confirmed a 4% increase to the energy price cap for the period covering 1 October to 31 December 2026, setting the cap at £1,723 per year for a typical dual-fuel household paying by Direct Debit (Ofgem). The price cap is a government-set ceiling on what energy suppliers can charge households on default tariffs — think of it as a regulator-imposed speed limit on prices, adjusted quarterly to reflect wholesale market costs. This latest adjustment follows a 13% rise that took effect at the start of July, which Ofgem attributed to global energy market price increases driven by the US war on Iran and the closure of the Strait of Hormuz (Ofgem). Cornwall Insight, an energy analytics firm, forecasts the October cap will mark a three-year high (Reuters.
UK government sources indicated that households are unlikely to receive further broad energy-bill support before the October cap takes effect, though targeted measures could be considered if a further price shock materialises in January (The Guardian). The stance leaves the principal relief mechanism as the removal of the 5% VAT on domestic electricity bills, announced in Prime Minister Andy Burnham's first week in office and effective from 1 October. The Treasury expects the VAT cut to reduce the annual Ofgem price cap by approximately £45, layering on top of roughly £150 already removed from average bills under Budget 2025 measures that took effect in April (GOV.UK; GOV.UK).
Burnham acknowledged that rising bills were "difficult for people" but stopped short of promising intervention beyond the VAT cut (The Guardian). Energy secretary Miatta Fahnbulleh said bills were being driven up by the Iran war and that the government would "keep looking at what more could be done to protect families from unaffordable bills." Chancellor John Healey said the government would revisit whether further support was needed towards the end of the year. Government sources suggested any additional measures would be costed in the budget, with officials waiting to see how the Gulf conflict develops over the coming months.
The broader context here is one of deliberate fiscal strategy. The government appears to be containing immediate political pressure through the VAT removal while keeping its options open for the January cap period, when forecasts from Cornwall Insight cited by the Resolution Foundation suggest bills could rise by up to 9%. That sequencing aligns with a Treasury logic of calibrating any further intervention to the trajectory of the Gulf conflict rather than committing fixed spending now against an uncertain commodity-price backdrop.
The Resolution Foundation, an independent thinktank focused on living standards, recommended that targeted support be designed, costed, and ready to activate from January if needed. Its proposal would direct assistance beyond existing benefit recipients to households earning under £24,000 a year, reaching approximately 40% of households with potential average savings of £175 for eligible families (The Guardian). The thinktank's framing effectively challenges the government's wait-and-see approach by arguing that the design work should occur now, even if disbursement is deferred.
The Trades Union Congress (TUC), Britain's largest union federation, renewed its call for a windfall tax — a one-off tax on what are deemed to be excess profits — on bank profits to fund cuts to energy bills. TUC general secretary Paul Nowak said the government should examine funding mechanisms now, including taxing banks' profits, to deliver more household support this winter (The Guardian).
The current posture also marks a departure from the preparatory work of former chancellor Rachel Reeves, who before Burnham's premiership had been developing targeted energy-bill support. Reeves told the Commons in March that she wanted a targeted approach in place by autumn. The transition to the Burnham government appears to have substituted the VAT cut for that more granular framework, at least for the immediate cap period.
For perspective, the energy price cap trajectory remains well below its crisis peak. The cap for a typical household rose from £1,277 in winter 2021-22 to over £4,000 by the start of 2023 (GOV.UK). The October 2026 figure of £1,723, before the £45 VAT reduction, sits substantially below that peak but above pre-crisis norms. Separately, households eligible for the £150 Warm Home Discount through means-tested benefits were required to be named on their energy bill by 23 August to qualify (GOV.UK).
The political stakes for the Burnham government are sharpened by the dual exposure to Gulf-driven wholesale gas prices and the compressed timeline between the October cap and the January review. If the Strait of Hormuz disruption persists or deepens, the 9% January upside scenario becomes a baseline rather than a tail risk, and the fiscal space created by waiting narrows considerably. The Resolution Foundation's argument for pre-costed contingency measures is, at its core, a bet that the government's optionality will prove more expensive than proactive design.
