The Announcement
On 21 July 2026, HM Treasury and the Prime Minister’s Office announced a tax cut: VAT on domestic electricity bills will be reduced from 5% to 0%, effective 1 October 2026, aimed at easing cost-of-living pressures ahead of winter. (gov.uk)
Who Benefits and Key Details
- All UK households buying electricity for domestic use.
- Northern Ireland households will be supported via equivalent funding through the NI Executive to ensure parity, given EU VAT rules require EU-aligned VAT rates in NI. (gov.uk)
Economic Impacts and Scale of Support
- Estimated cost to the government: approximately £850 million in 2026-27.
- Expected to reduce CPI inflation by ~0.10 percentage points and RPI (Retail Price Index) by ~0.14 points. (gov.uk)
Practical Actions for Households and Advisors
- Check electricity supplier bills from October; consumers should see a drop in the VAT component.
- Energy budgeting: use savings from VAT drop to offset other rising costs.
- Benefit claimants should see no adverse impact on eligibility for means-tested support, but check local guidance.
- Business implications: while this is for domestic supply only, businesses supplying electricity may need to adjust invoicing where domestic/residential consumption is concerned.
Limitations & Things to Confirm
- The cut applies from 1 October 2026 onward—not retroactively.
- Some fixed-tariff plans may lag in reflecting the reduction—suppliers are expected to pass on savings including for customers under fixed tariffs. (gov.uk)
- This is a short-term relief ahead of Budget where further cost-of-living or energy support could be set out.
Case Example: A household spending £800/year on domestic electricity (before VAT) was paying an extra £40 (5%). From October, that extra cost is removed—saving roughly £40 annually. Combined with supplier competition this could increase savings if base prices don’t change upwards.
