The Non-Domestic RHI Register will will be unavailable on Saturday 28 April between 9am and noon due to essential maintenance work. During this time you can email and we will contact you as soon as possible during our normal office hours.

Who is the scheme for?

The Non-Domestic Renewable Heat Incentive (RHI) is open to industrial, commercial, public sector and non-profit organisations with eligible installations in Great Britain.

This includes small businesses, hospitals and schools as well as district heating schemes where one installation serves multiple homes.

Biomethane producers have different registration requirements which can be found in Guidance Volume 1, Chapter 12.

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.

Further information can be found by reading the Easy Guide to Applying, Easy Guide to Eligibility, FAQs, and correct installations illustrations.
