The November 2025 Budget set out measures that the government said would reduce energy bills by around £150 a year, with the reduction taking effect from 1 April 20261. The change came mainly from how government schemes are funded: the Renewables Obligation is now part-funded by the government for three years to March 2029, and the Energy Company Obligation ended on 31 March 20261. Both had previously been paid for through energy bills1.
The confirmed figure is lower than the one announced. The latest price cap update confirms an average reduction of around £117 a year for a typical household, because other network and system costs rose; without the government's intervention the price cap would have gone up1. The typical household is defined by Ofgem as a dual fuel customer paying by Direct Debit who uses 2,700 kWh of electricity and 11,500 kWh of gas a year1. Most of the reduction applies to electricity prices, with a smaller reduction on some gas tariffs, and electricity standing charges have increased slightly1. Suppliers' reductions can vary, because suppliers have different costs and took part in government schemes in different ways1.
Nesta, an independent research body, states that the war in Iran has already caused wholesale gas prices to rise by around 50% since the invasion, and that this surge is likely to eliminate the £150 reduction announced in November 20252. It puts the wholesale gas price allowance in the Ofgem price cap at 2.71 p/kWh for April to June 2026, and says prices would need to reach around 10p/kWh to return to the £2,500 level at which the government capped them in 20222.
"This surge is likely to eliminate the £150 energy bill reduction announced in November 2025, and prices could get much worse."
Nesta's note proposes a response centred on accelerating energy efficiency measures and speeding up the adoption of electric heating technologies in the home2. It says the government has uplifted the Boiler Upgrade Scheme grant to £9,000 for heating oil and LPG users, and that it abandoned its Energy Efficiency Taskforce soon after launching it2. It also records that the electricity-to-gas price ratio fell to 3.2 in April 2023 under the Energy Price Guarantee, and would have bottomed out at 3.5 in October 2022 under the default tariff cap2.
| Item | Figure |
|---|---|
| Reduction announced at the November 2025 Budget | Around £150 a year1 |
| Reduction confirmed in the latest price cap update | Around £117 a year for a typical household1 |
| Wholesale gas price allowance in the price cap, April to June 2026 | 2.71 p/kWh2 |
| Wholesale gas price rise since the invasion of Iran | Around 50%2 |
Why it matters for households
The £150 was delivered through lower unit rates rather than a payment, so it shows up in the cost per unit of electricity and gas used1. That means the size of any saving depends on how much energy a home uses and which tariff it is on, and a household using relatively little electricity and more gas may not see as large a reduction as the typical household used in the price cap calculation1. The reduction applies to almost all customers of at least one supplier even on a fixed tariff, though some gas tariffs are unchanged where the supplier was not part of the ECO scheme1.
For a home's energy independence, the two developments pull in opposite directions. The Budget change reduced the policy costs carried on bills, but it did not change how much gas a home burns, and gas remains the fuel that sets the marginal price of electricity most of the time2. Nesta's figures show how far wholesale gas would have to rise to undo the saving entirely2. The price cap history sets out how levels have moved since 2019, and the policy costs and levies page explains which scheme costs sit inside a bill. Standing charges, which rose slightly on electricity, are covered in standing charges on energy bills.
What happens next
The reduction takes effect from 1 April 20261. The government has committed to part-funding the Renewables Obligation until March 20291. Nesta's note is dated 27 April 2026 and sets out recommendations rather than confirmed policy2. No further dated decisions on the level of support have been reported.
