Heat Pump Grant Wales: Nest Scheme and BUS Grant Guide 2026

By Home Heat Pump Guide

Welsh homeowners have two routes to funded heat pumps — the Nest scheme for free installations, and the BUS grant for £7,500 off.

Welsh homeowners have a unique advantage: two separate funding routes for heat pumps. The Nest scheme can cover the entire cost for low-income households, while the Boiler Upgrade Scheme provides £7,500 off for everyone else who qualifies. Either way, you could save thousands.

This guide explains both schemes, who qualifies for each, and how to make the most of the funding available to you in Wales.

If you qualify for Nest, that is usually the better option. If you do not, the BUS grant provides substantial help.

The Nest Scheme: Free Heat Pumps for Eligible Households

The Nest scheme provides free heat pump installations to low-income Welsh households — covering the full cost.

Nest is the Welsh Government's fuel poverty programme. It provides free or heavily subsidised home energy improvements, including heat pump installations, to eligible Welsh households.

What Nest Covers

  • Free heat pump installation for qualifying households
  • Free insulation (loft, cavity wall, external wall)
  • Free energy advice for all Welsh households

Nest Eligibility

You are more likely to qualify if you:

  • Receive means-tested benefits (Universal Credit, Pension Credit, income-based ESA, etc.)
  • Live in a home with an EPC rating of E, F, or G
  • Have a household income below a certain threshold

How to Apply for Nest

Call the Nest helpline on 0808 808 2244 or apply through their website. An advisor will check your eligibility and guide you through the process.

The BUS Grant in Wales

Welsh homeowners who do not qualify for Nest can access the Boiler Upgrade Scheme. The eligibility criteria are the same as for English homeowners — own the property, have a valid EPC, be replacing fossil fuel heating, and use an MCS-certified installer.

Your installer handles the application through Ofgem. The £7,500 is deducted directly from your installation quote.

Which Scheme Is Right for You?

Check Nest eligibility first — if you qualify, you pay nothing. If not, the BUS grant still saves you £7,500.
  • On benefits or low income? Check Nest first — call 0808 808 2244
  • Not on benefits but own your home? The BUS grant gives you £7,500 off
  • Renting? Ask your landlord to apply for BUS, or check if your landlord can access Nest
  • Social housing? Your housing provider may access the Social Housing Decarbonisation Fund

Welsh homeowners adding solar panels alongside a heat pump can access separate solar funding — the two technologies complement each other brilliantly and reduce ongoing electricity costs.

About Welsh Heat Pump Grants

Wales benefits from both the Welsh Government's Nest fuel poverty programme and the UK-wide Boiler Upgrade Scheme. Together, they ensure that virtually every Welsh homeowner has access to some form of heat pump funding. Air source heat pumps are the most common choice, though ground source systems are also funded. The broader UK grants landscape includes ECO4 and local authority schemes. Welsh homeowners exploring whole-home energy efficiency can also consider solar panels to reduce electricity costs further.
