The Boiler Upgrade Scheme in 2026: what the £7,500 grant actually covers

The Boiler Upgrade Scheme was extended and the grant amount increased to £7,500 for air source heat pumps — but the eligibility criteria also changed. Not every home qualifies, and the scheme's conditions mean some properties are better suited than others.

The key change for 2025 is that the property must have a valid EPC with no outstanding recommendations for loft or cavity wall insulation. This is designed to ensure heat pumps are installed in homes where they'll perform well — not just where the grant makes them look financially attractive.

If you're considering a heat pump under the BUS, the most important step is getting a proper survey. We'll tell you honestly whether your home is a good candidate before you commit to anything.
