What's the RHI scheme?

The Domestic Renewable Heat Incentive (RHI) is a UK Government scheme set up in April 2014 to encourage householders to use renewable heat technologies. The RHI’s aim is to help reduce carbon emission and meet the Government’s renewable energy targets. The Domestic RHI provides financial support to the owner of the renewable heating system for seven years. The scheme covers England, Wales and Scotland.

If you’re eligible, you’ll receive quarterly payments over seven years. The amount you receive will depend on the technology you use and the latest tariffs available.

Which renewable technologies does the scheme cover?

The RHI supports the following technologies:

  • Biomass (wood fuelled) boilers
  • Biomass pellet stoves
  • Ground source heat pumps
  • Air source heat pumps
  • Solar thermal panels

Water source heat pumps, certain cooker stoves and some high temperature heat pumps may also be eligible. Air to air heat pumps, all log stoves, pellet stoves without back boilers and hybrid PVT aren't supported by the RHI.

How can I apply for the Renewable Heat Incentive?

You can apply for the scheme online. You’ll most likely receive an immediate decision on whether you're eligible once you have completed your application.

You may need to provide more information. If this happens, your application will be put into review. Ofgem will let you know what information they need from you within five days. You’ll have 28 days to then provide the information. Your payment will still be calculated from the date you applied.

If you’re unable to apply online then you can contact Ofgem’s Domestic RHI Applicant Support Centre on 0300 003 0744 Monday to Friday from 9am to 5pm.

To apply you’ll need:

Government and public fund grants

If you’ve already received a grant from Government or public funds (such as the Renewable Heat Premium Payment), you’ll also need to provide details of:

  • Your received payment amount
  • Your payment date
  • The installation cost
  • The Seasonal Performance Factor (only heat pumps applications)
  • The Installing Meter Questions form (only metering systems applications)
