Wales Heat Pump Grant — £7,500 BUS + Nest

Wales uses the same £7,500 Boiler Upgrade Scheme as England — applied by your MCS installer. Plus the Welsh Government's Nest scheme can cover 100% of installation cost for eligible low-income households.

£7,500 BUS · plus Nest scheme
Same UK grant as England, plus Welsh-only Nest scheme covering 100% install for eligible low-income households.
Quick answer: Wales uses the £7,500 Boiler Upgrade Scheme (BUS) — same rules as England, applied by your MCS installer. Additionally, the Welsh Government's Nest scheme covers up to 100% of installation cost for eligible low-income households (means-tested). Most Welsh homeowners use BUS; low-income households should check Nest first as it's more generous when eligible.

The £7,500 BUS for Wales

Wales uses the same Boiler Upgrade Scheme as England — administered by Ofgem with identical rules. £7,500 for any air source or ground source heat pump installed by an MCS-certified installer.

The application process is identical to England:

  1. Get a valid EPC (no outstanding insulation recommendations)
  2. Get quotes from MCS-certified installers
  3. Installer pre-approves the BUS application with Ofgem
  4. Install and commission (2-4 days for ASHP)
  5. Ofgem pays £7,500 to installer within 4-6 weeks

The Welsh-only Nest scheme

Nest is the Welsh Government's flagship fuel poverty programme, run by Warm Wales. It's separate from BUS and offers much more generous funding for eligible households:

Nest eligibility criteria

You qualify for Nest if you own (or privately rent) a Welsh home AND meet at least one of:

If you qualify for Nest, take it — it's a better deal than BUS. If not, BUS is your route.

Can I combine BUS and Nest?

No — they're alternatives, not stackable. You apply for one or the other. Nest is more generous for eligible households (covers 100%), so if you qualify, choose Nest.

Welsh local council schemes

Some Welsh councils run additional top-up schemes for heat pumps:

Ask your local council's housing/energy team. These vary year-to-year as council budgets are set.

Common questions

Does Wales have a separate heat pump grant from England?
Wales uses the same £7,500 Boiler Upgrade Scheme (BUS) as England. The Welsh-specific addition is the Nest scheme, which covers up to 100% of install cost for low-income households (means-tested).
What's the Nest scheme?
Nest is the Welsh Government's fuel poverty programme. For eligible low-income or vulnerable households, it pays 100% of heat pump installation cost (plus insulation if needed). Apply at nest.gov.wales or call 0808 808 2244.
Can I get BUS as a Welsh tenant?
Not directly — the grant goes to property owner. Your landlord can apply if it's a private rental. Social housing tenants should ask their housing association about Warm Wales Plus or council-led schemes.
Is the BUS grant taxable in Wales?
No — the grant is deducted from your installer's invoice and never passes through your hands. There's no income tax implication.
What about EPC requirements in Wales?
Same as England: valid EPC (under 10 years old), no outstanding loft or cavity-wall insulation recommendations. Get a new EPC if yours is older or has unaddressed recommendations.
