Heating grants by country

1 England

The Boiler Upgrade Scheme funds heat pumps and some biomass, not gas boilers¹. Warm Homes: Local Grant is England-only: the home must be privately owned with an EPC of D to G, and household income must usually be £36,000 a year or less, with routes by postcode or benefit⁴. The page lists insulation, heat pumps, smart controls and solar panels as examples and does not mention gas boilers⁴.

2 Wales

The Boiler Upgrade Scheme applies here too¹. The Welsh Government's Nest page says eligible households get free home energy improvements, which "could include a boiler repair or replacement, heat pump, insulation and solar panels"⁵. You must own or privately rent, receive a means-tested benefit or live on a low income, and have an EPC of 54 (E) or less, or 68 (D) or less with an eligible health condition⁸. Neither page shows a date.

3 Scotland

Home Energy Scotland offers a grant up to £7,500 for heat pumps and heat network connections, plus an optional interest-free loan up to £7,500². Efficiency measures can get up to 75% of combined cost, to a £7,500 maximum, and a £1,500 uplift applies in rural and island areas². Gas boilers are not in that funding table². Heat pumps must supply all heating and hot water, so hybrids are out².

Warmer Homes Scotland is separate, and its page lists "new gas boiler" as a possible central heating measure, depending on an assessment and eligibility based on age, medical certificates or benefits⁶.

4 Northern Ireland

GOV.UK says the NI Boiler Replacement Scheme is closed, and points readers to Affordable Warmth for energy help³. The Affordable Warmth page itself could not be reached, so its terms are not given here. Check nidirect directly. The Warm Home Discount below does not cover Northern Ireland⁹.

5 Across Great Britain

The Warm Home Discount is a one-off £150 off the electricity bill, running to 31 March 2031 in England, Wales and Scotland; the England and Wales qualifying date this winter was 23 August 2026⁹¹⁰.

ECO4 closes on 31 December 2026⁷. Ofgem says it is not a grant scheme and a supplier need not act, so do not plan around it for any date after that¹¹. The Great British Insulation Scheme has closed to new installations, having ended on 31 March 2026¹².

The Warm Homes Plan describes low and zero interest loans and a new Warm Homes Agency, but no live application route for these was read¹³. VAT is covered under replacing a boiler.
