How the heat pump grant works
You agree a quote with a certified installer. They deduct the grant and apply. Ofgem decides. You do not send the application yourself.
Key takeaways
- One grant per property.
- The discount should show on the quote and the invoice.
- You must end up owning the heat pump. Some finance arrangements fail that test.
- A checker result is not an approval.
The steps
Choose an installer who can fit the system and apply for the grant. They survey the home, say which grant category they think applies, and show that amount as a deduction. You agree the quote. They apply. If Ofgem agrees, the installer is paid the grant and your bill is the price after that deduction.
GOV.UK’s what you can get page is the public summary. The longer rules sit in Ofgem’s property owner guidance. Where those two read differently, the values notice decides the pound amount and the guidance decides the property rules.
Limits worth knowing
You can get one grant for the property. The system has a maximum capacity: 45kWth for a single system, higher where extra heat pumps or a shared ground loop are used. Hybrids are excluded. Most new builds are excluded, with a narrow self-build exception that your installer has to evidence.
If a finance deal leaves the heat pump owned by the lender or the installer, Ofgem’s guidance says that arrangement is not eligible. Read that before you sign. This site does not offer credit.
Where the checker fits
The eligibility checker answers the public categories: country, owner or tenant, current heating, property type, heat pump type, and new build. It cannot see your title deeds, your flue, or whether the installer will be paid.
Use checker vs the scheme page if you want to know what this site leaves to Ofgem.
