ECO4 Scheme
The Energy Company Obligation (ECO4) is the largest free heat pump scheme in the UK. Large energy suppliers are legally required to fund energy efficiency improvements in low-income homes. ECO4 can cover the full cost of a heat pump plus insulation.
Nest Scheme (Wales)
The Nest scheme provides free heat pump installations to low-income and vulnerable Welsh households. Call 0808 808 2244 to check eligibility.
Warmer Homes Scotland
Delivered through Home Energy Scotland, this scheme provides free energy improvements including heat pumps for low-income Scottish households. Call 0808 808 2282.
Social Housing Programmes
The Social Housing Decarbonisation Fund (SHDF) funds heat pump installations in council and housing association properties. If you are a social housing tenant, your landlord manages this process.
Local Authority Schemes
Some local councils run their own fully funded heat pump programmes, targeting specific areas or household types. Contact your council's energy or housing team to check.

What If You Do Not Qualify for Free?
If you do not meet the criteria for free schemes, the BUS grant provides £7,500 off, and alternative finance options can spread the remaining cost. In Scotland, the HES interest-free loan can eliminate upfront costs entirely.
Even without free installation, a grant-funded heat pump paired with solar panels can generate significant long-term savings on energy bills.

About Free Heat Pump Schemes in the UK
Free heat pump programmes form a critical part of the UK's strategy to tackle fuel poverty while decarbonising home heating. ECO4, Nest, and Warmer Homes Scotland collectively ensure that low-income households are not left behind in the transition to renewable heating. Air source heat pumps deliver efficient, low-cost heating that can transform household energy bills. For households that combine a heat pump with solar panels, the reduction in energy costs can be even more dramatic.
