How Much Could You Earn?

How much you could earn depends on the technology you choose, and the tariffs set out by the government (measured in pence per kilowatt-hour for the renewable heat produced). Payment calculations are based on an estimate of how much heat your home will require from a renewable heating system and how it will perform once installed. As well as the technology itself, performance will also depend on other factors, such as insulation levels and the heat emitters your system uses (for example, low-temperature underfloor heating is likely to be more efficient than traditional radiators). Before applying for RHI payments you will need an up-to-date Energy Performance Certificate (EPC), which shows how efficient your property is. If your EPC recommends loft and cavity wall insulation it must be installed, and the EPC replaced prior to applying. There are some circumstances under which you may be exempt from this requirement for which you must submit evidence.

Who Is Eligible?

Anyone who retrofits an air source or ground source heat pump in a single domestic property is eligible for RHI payments (whether they are an owner-occupier or private/social landlord). Self-build properties are the only new-build installations that are eligible. To qualify for RHI payments, your system needs to have been fitted by an installer who has the right training and accreditation under the Microgeneration Certification Scheme (MCS).

Example figures:

A GSHP fitted in a typical three-bedroom house could generate annual payments of around £2,287 per year. *

10.71P/KWH Air Source heat pump

An ASHP fitted in a typical three-bedroom house could generate annual payments of around £1,012 per year. *

20.89P/KWH Ground Source heat pump

A GSHP fitted in a typical three-bedroom house could generate annual payments of around £2,287 per year. *
