The price cap will hit £1,923 from October, a £63 rise in three months. Yet buried in the announcement is a six-month VAT holiday on electricity: 5% scrapped from 1 October until 31 March 2025. For a typical 3-bed semi using 12,000 kWh of electricity a year, that shaves about £30–£35 off the bill over the period. Not nothing. But not a solution.
As reported by Money Saving Expert, the cut applies automatically, no application needed. But the catch is that it is temporary. And it only applies to electricity, not gas. Households on dual-fuel tariffs will see the electricity portion fall slightly while the gas portion stays taxed at 5%.
Who qualifies, and who doesn’t
Every domestic electricity customer in Great Britain qualifies. Those on standard variable tariffs, fixed deals, or prepayment meters all get the reduction. Businesses and public sector buildings do not. The cut is applied at source by suppliers, so nobody needs to claim anything. But note: if you are on a fixed tariff that already includes VAT, your supplier should adjust the rate automatically, check your next bill to confirm.
The saving is modest because VAT on energy is already at the reduced rate of 5%. The government chose not to cut VAT on gas, which makes up roughly 60% of the typical dual-fuel bill for a gas-heated home. So a household using 12,000 kWh of gas and 3,000 kWh of electricity might see only £8–£10 saved on the gas portion, if the cut applied. It doesn’t.
What it costs a typical 3-bed semi
Ofgem’s typical domestic consumption values (TDCVs) for a 3-bed semi with gas heating: 2,900 kWh electricity, 12,000 kWh gas. At the October cap of 24.5p/kWh for electricity, the annual electricity bill is roughly £710. VAT at 5% is £35.50. For six months, the saving is about £17.75. If you use more, say an all-electric home with a heat pump using 6,000 kWh, the saving doubles to about £35 over the period.
Energy Saving Trust figures suggest the average household spends £1,800 a year on energy. A £30 saving is 1.7% of that. Compare that to the £500+ added to bills since 2021. The VAT cut is a sticking plaster on a wound that needs stitches.
The bigger picture: VAT vs efficiency
What this misses is the structural problem: the UK has the least energy-efficient housing stock in western Europe. The average EPC rating is D. Loft insulation, cavity wall fill, double glazing, and heat pumps all deliver savings of £200–£600 a year per measure, permanent savings, not six-month fixes. The government’s Boiler Upgrade Scheme offers £7,500 off a heat pump. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing.
Yet the VAT cut does nothing to encourage those upgrades. It is a blunt instrument that helps everyone a little but changes nobody’s behaviour. A smarter move would have been to make the VAT cut conditional on taking an energy efficiency measure, as the French do with their MaPrimeRénov’ scheme. But that would require administration, and this is a quick political fix.
What to do now
Check your October bill to confirm the 0% VAT rate is applied. If it isn’t, call your supplier. Then use the £30–£35 saved to pay for a home energy audit, or put it toward loft insulation. The real savings come from cutting consumption, not taxing it less. The VAT holiday ends on 31 March 2025. By then, you want to be using less energy, not just paying less tax on it.
Frequently Asked Questions
No. The reduction from 5% to 0% is applied automatically by your supplier. You do not need to contact anyone or submit a form. Check your October bill to confirm the change has been made.
No. The six-month VAT holiday applies only to domestic electricity. Gas remains at 5% VAT. Households with gas heating will see a smaller overall saving than all-electric homes.
