The 5% VAT cut on domestic energy bills saves the average household £67 a year. That is less than the cost of a single boiler service in much of the South East.
Martin Lewis has described the measure as a ‘sticking plaster’, as reported by North Wales Live. He is right, but the real question is why the cut exists at all, and what it reveals about the government’s approach to energy costs.
Who qualifies, and who doesn’t
The VAT cut applies to all domestic energy supplies: electricity, gas, heating oil, and solid fuels. It reduces the rate from 5% to 0% for the period 1 April 2022 to 31 March 2027. The Treasury estimates it costs about £1.5bn a year in forgone revenue.
But the cut is universal. A household in a draughty 4-bed detached with high consumption saves more in absolute terms than a flat-dweller in a modern block. That is regressive in effect, even if the rate is flat. The Energy Saving Trust notes that low-income households spend a higher proportion of their income on energy, yet the cut gives them a smaller cash saving than wealthier counterparts.
What it costs a typical 3-bed semi
On a typical annual dual-fuel bill of £1,340 (Ofgem’s latest cap figure for direct debit), the 5% VAT amounts to £63.80. For a household on prepayment, often the most vulnerable, the saving is slightly lower because the cap is set differently. The difference is about £5 a year.
Compare that to the cost of a heat pump installation: typically £7,000 to £13,000 after the Boiler Upgrade Scheme grant of £7,500. The VAT cut saves you £67. The heat pump saves you £200–£400 a year on heating bills, depending on your old system. The arithmetic is brutal.
The ‘but’ pivot, what the cut does not fix
What this misses is the structural problem: the UK has some of the least efficient housing stock in Europe. The average EPC rating is D. Insulating a loft costs around £500 and saves £200 a year, a payback of 2.5 years. Cavity wall insulation costs £1,000 and saves £250 a year. Both are zero-VAT anyway under current rules for installation services.
Yet the government chose a universal VAT cut over targeted efficiency grants. The Social Housing Decarbonisation Fund and the Home Upgrade Grant exist, but they reach a fraction of eligible households. The cut is a political gesture, not a policy for reducing bills.
What homeowners should actually do
For anyone reading this, the message is simple: ignore the VAT cut in your planning. It is a small, temporary relief. What matters is permanent reduction in energy use.
Start with an EPC assessment (costs £60–£120). Then prioritise: loft insulation first, then cavity walls, then draught-proofing, then heating system. The Boiler Upgrade Scheme is open until 2027 and covers heat pumps and biomass boilers. The Great British Insulation Scheme offers free or subsidised insulation for low-income households.
The VAT cut will be gone by 2027. Your insulation will still be saving you money in 2040.
Frequently Asked Questions
Yes, domestic electricity, gas, heating oil, and solid fuels are all included. The rate drops from 5% to 0% until 31 March 2027. It applies automatically; you do not need to apply.
No. The cut saves about £67 a year. Loft insulation costs £500 and saves £200 annually. Efficiency upgrades pay for themselves within a few years and continue saving for decades.
