The government’s announcement, made in July by new Prime Minister Andy Burnham as one of his first acts in office, frames the electricity VAT cut as immediate relief ahead of winter. For households and the businesses that supply or advise them, the detail matters more than the headline figure.
The zero rate runs from 1 October 2026 to 31 March 2027, covering the remainder of the current financial year. It is expected to strip around £45 a year off the typical bill under the Ofgem price cap, and the Treasury puts the cost to the public purse at roughly £850 million for 2026-27, funded by cancelling the planned Digital ID programme rather than fresh borrowing. Whether the relief continues past March 2027 will be decided at the Autumn Budget.
Suppliers must apply the reduction automatically, including to customers on fixed-rate tariffs — the change affects the tax component of a bill, not the unit price, so a fixed deal offers no shelter from it.
The relief is electricity-only. Domestic and qualifying gas supplies stay on the 5% reduced rate; standard-rated business gas remains at 20%. HMRC’s existing guidance on fuel and power is unchanged in that respect, and there’s no indication the zero rate will extend to heating oil, LPG or other qualifying fuels.
The rules on electricity VAT for UK businesses extend beyond ordinary domestic bills, but only for organisations that meet the qualifying conditions:
Organisations relying on a supplier declaration to secure the reduced rate should expect the same mechanism to carry over to the zero rate — worth revisiting where usage is mixed between qualifying and non-qualifying purposes.
Northern Ireland keeps the 5% rate. Windsor Framework rules tie electricity VAT there to EU law, which the UK cannot amend unilaterally — the executive instead receives equivalent funding. Because the electricity VAT cut 2026 does not extend to Northern Ireland, multi-site operators with premises on both sides of the Irish Sea should budget for bills that diverge from October.
A second gap sits with electric vehicles. Under Revenue and Customs Brief 4 (2026), HMRC treats electricity at public charge points as standard-rated because the supply isn’t made to a dwelling. From October, home charging carries no VAT, while public charging still carries 20% — a gap fleets reimbursing mileage should model before winter.
Ofgem’s Energy Price Cap is updated every three months, and the next cap period begins on 1 October, the same day the electricity VAT cut takes effect. MoneySavingExpert has warned that the expected £45 saving could be largely offset by a forecast rise in the October Price Cap. Martin Lewis noted that rising wholesale energy costs could mean many households see little of the headline saving in practice. The £45 figure should therefore be treated as an estimated saving rather than a guaranteed reduction in overall energy bills.
The new VAT rate may affect more than just your electricity bill. Finance teams, care providers, landlords and energy-intensive small businesses may need to update billing systems, review supplier certificates and check how the change is reflected in VAT returns from 1 October.

From 1 October 2026 to 31 March 2027, covering the rest of the current financial year.
No. Gas stays at the existing rates—5% for qualifying domestic use and 20% standard-rated for business supplies.
Only where they already qualify for domestic-use energy VAT relief, typically small users below the de minimis threshold, alongside charities and care homes.
No. Northern Ireland remains on the 5% rate due to Windsor Framework rules; the Executive receives separate compensating funding instead.
Yes. Suppliers are expected to apply the reduction regardless of tariff type, since it removes tax rather than changing the unit price.
Partially. The Ofgem price cap is reviewed on the same date the cut begins, and a forecast increase may reduce the net benefit below the headline £45 figure.
