Rules and grants

Landlords need band C by 1 October 2030. Check a rented home with the landlord EPC calculator.

ECO4 can fund insulation for households on qualifying benefits until 31 December 2026, and the Boiler Upgrade Scheme gives £7,500 off a heat pump.

How we worked this out

EPC bands and home features: English Housing Survey 2024, live tables DA7101, DA6201 and DA6101 (MHCLG, updated 9 July 2026), England. Gas use: NEED consumption tables 2026 (DESNZ), 2024 meter readings, England and Wales, whose age bands differ slightly from the survey's. The routes to band C are our simple EPC points model, the same as our EPC calculator, not the government's SAP software, for a home with loft insulation, double glazing and a gas boiler under 15 years old.

Frequently asked questions

What EPC rating does a late 1960s and 1970s home usually have?

Band D on average: homes built between 1965 and 1980 average 68 points in the English Housing Survey 2024, against 68 for all homes. About 62% are band C or better, and 6% are band E or worse.

Can a late 1960s and 1970s home reach EPC band C?

Yes: 62% of homes built between 1965 and 1980 are already band C or better. For a 1970s semi with unfilled cavity walls, about £275 in our model, starting from band D.

Why do older homes have lower EPC ratings?

Walls are a big part of it. The rating models what a home costs to heat per square metre, and solid walls lose far more heat than filled cavity walls; 79% of homes built before 1919 have solid walls with no insulation.
