Heat pump grants in Wales
Two routes: the UK-wide grant, and the Welsh Government fuel poverty scheme.
Households in Wales can claim the £7,500 Boiler Upgrade Scheme grant for an air source heat pump, exactly as in England (GOV.UK, 2026). Eligible low-income households can alternatively access the Welsh Government’s Nest scheme, which provides free energy efficiency and heating improvements rather than a fixed grant amount.

Route 1 — Boiler Upgrade Scheme
Available to owner-occupiers and private landlords in Wales. The property needs a valid EPC without outstanding loft or cavity wall insulation recommendations, and the installer must be MCS-certified. The grant is applied as a discount on your invoice.
Route 2 — Nest
- Welsh Government scheme aimed at fuel poverty.
- Free advice for all Welsh households; free improvements for those who qualify.
- Eligibility is based on income, benefits and the energy efficiency of the home.
- Takes a whole-home view: insulation is usually addressed alongside heating.
Welsh housing stock considerations
Wales has a high proportion of solid-wall and rural off-gas properties. Off-gas homes on oil or LPG see the largest running cost improvement from a heat pump, and external or internal wall insulation often has a bigger effect on the final bill than the choice of heat pump model.
