How Much Does an Air Source Heat Pump Cost in the UK in 2026?
Air source heat pumps are now one of the UK’s leading low‑carbon heating options especially as government support evolves in 2026 under the new Warm Homes Plan.
Typically, installing an air source heat pump can cost £8,000–£18,000 for most UK homes, with the average falling around £12,000–£13,000 once materials, labour and any home upgrades (like larger radiators or hot water cylinders) are included. That initial price tag can seem high compared with a traditional gas boiler, which usually costs a few thousand pounds to replace.
However, the Warm Homes Plan includes grant funding aimed at reducing these upfront costs, especially for lower‑income households. Through Warm Homes: Local Grant schemes, eligible homeowners (generally based on income, benefits and energy performance of the property) can receive significant support in some cases covering much of the heat pump installation cost alongside other energy‑improvement work. Local delivery varies across councils and is part of government investment in energy efficiency and clean heat.
Alongside this, the Boiler Upgrade Scheme continues to offer £7,500 off the cost of an air source heat pump in England and Wales, with the installer claiming the grant on your behalf.
This combined approach makes heat pumps far more affordable than the headline price suggests, helping households cut carbon emissions and lower long‑term energy bills.
