Boiler upgrade scheme.
Am i eligible?
The grant is actually quite a simple, straightforward process and something most homeowners can get hold of easily. We take care of the application for you.
You’re eligible for a grant if both of the following are true. You must:
-
own the property you’re applying for (including if it’s a business, a second home, or a property you rent out to tenants)
-
be replacing fossil fuel heating systems - such as oil, gas, electric or LPG (liquefied petroleum gas)
You’re still eligible if you’ve already had funding to make your property more energy efficient, for example by insulating it.
Your property must have a valid EPC to to obtain the grant. You used to have to have an EPC of a D or above, but this is no longer the case. New technology means heat pumps are capable of heating property's with poor insulation levels, although its still best to insulate as much as possible to maximise efficiency.
