The number is striking: 250,000 households could cut their energy bills by £620 a year. That is nearly 10% of the average annual dual-fuel bill, currently around £1,568 under the October price cap. For a household on a low income or living in a draughty property, £620 is not pocket change, it is a week’s shopping or a month’s transport costs.
The plan was reported by the Daily Express, though the exact mechanism remains vague. As reported by the Daily Express, the proposal targets a specific subset of homes, likely those with poor energy performance, high heating demand, or eligibility for social tariffs. The £620 figure assumes a typical 3-bed semi using 12,000 kWh of gas and 2,900 kWh of electricity, a standard assumption used by Ofgem for bill comparisons.
Who qualifies, and who doesn’t
The 250,000 figure is not the entire UK. It is a fraction of the 28 million households in Britain. The plan probably focuses on those in fuel poverty or living in Energy Performance Certificate (EPC) bands D through G. The Energy Saving Trust estimates that upgrading a home from EPC band D to C can save £300–£500 a year on heating alone. Add better insulation, draught-proofing, or a heat pump, and £620 becomes plausible.
But the catch is eligibility. The Great British Insulation Scheme closed on 31 March 2026. It funded insulation measures only and never covered windows or glazing. If this new plan duplicates that, it helps only those who missed out before. If it expands eligibility, say, to all households with an EPC below C, then the 250,000 could be a starting point, not a ceiling.
What it costs a typical household
Let us translate the £620 saving into real-world action. For a home heated by gas, the biggest bill component is space heating, typically 60–70% of the total. Insulating a loft (cost: £300–£500 for a typical 3-bed semi) pays for itself in under a year if the home was uninsulated. Cavity wall insulation (£500–£700) takes two to three years. Draught-proofing (£100–£200) recovers costs in months. These are the low-hanging fruit that any plan should target first.
Yet the plan may also involve tariff restructuring, for example, a social tariff for households on prepayment meters or those with chronic illness. Ofgem has consulted on this since 2023, but no final decision has been made. The £620 could come from a combination of efficiency upgrades and a lower unit rate, but officials have not confirmed the split.
What this misses, and why you should act now
The plan is not yet policy. It has no start date, no application portal, no confirmed budget. Meanwhile, the winter heating season is months away. Homeowners should not wait for a headline to turn into a cheque.
The Great British Insulation Scheme is open now. It offers free or heavily subsidised insulation to households with an EPC below C and a Council Tax band A–D in England (or equivalent in Scotland and Wales). The scheme runs until March 2026. Similarly, the Energy Company Obligation (ECO4) provides free heating upgrades for low-income households. Check eligibility on gov.uk today.
For households not on benefits, the Boiler Upgrade Scheme (BUS) gives £7,500 off a heat pump installation, a grant that has been extended to 2028. A heat pump, combined with good insulation, can cut heating bills by 30–50% compared to an old gas boiler. That alone could exceed £620 a year for a large home.
The bottom line: the 250,000 figure is a promise, not a programme. The real savings come from action you take now. Visit the Energy Saving Trust website, book a home energy assessment, and apply for existing grants before winter bites. Do not wait for a plan that may never arrive.
Frequently Asked Questions
You can still save £620 or more by investing in low-cost measures yourself. Loft insulation, draught-proofing, and a smart thermostat typically cost under £1,000 and pay back within two years. Switching to a fixed energy tariff or a heat pump (with the £7,500 BUS grant) can also cut bills significantly.
