The Domestic Renewable Heat Incentive is the scheme for domestic customers.

What should I do if I want to apply?

Use this section to understand the joining requirements for the Non-Domestic RHI and the rules you need to stick to during your time on the scheme.

There are some key things to consider before you apply. You need to:

  • Be the owner of the installation (or have permission to act for the others if there are several owners).
  • Understand the eligibility requirements and your ongoing obligations.
  • Get documentation from manufacturers and installers as you’ll need to supply this evidence for your application. Keep this information safe as you may need it if you’re audited.

Read the relevant guidance documents on this website so your application goes smoothly.
