What is the Non-Domestic Renewable Heat Incentive?

The Non-Domestic Renewable Heat Incentive (RHI) is a government environmental programme that provides financial incentives to increase the uptake of renewable heat by businesses, the public sector and non-profit organisations.

Eligible installations receive quarterly payments over 20 years based on the amount of heat generated. The scheme covers England, Scotland, and Wales. There is a separate scheme for Northern Ireland. The Department of Enterprise, Trade and Investment suspended the Northern Ireland RHI Scheme to new applicants from 29 February 2016.

Who’s it for?

Businesses, public sector and non-profit organisations can apply if equipment was installed in England, Scotland or Wales on or after 15 July 2009 (or later in some cases). Your installation must meet certain requirements. There is further information about the Northern Ireland scheme.

Which scheme: Non-Domestic or Domestic?

The Renewable Heat Incentive has two schemes – Non-Domestic and Domestic. They have separate tariffs, joining conditions, rules and application processes. Ofgem administers both schemes in England, Scotland and Wales.

Each application can only be to one of the schemes. To decide which to apply for, see the information below, alongside our factsheet 'The Renewable Heat Incentive – Domestic or Non-Domestic?'

The Non-Domestic RHI

Generally, if the renewable heating system is in commercial, public or industrial premises, then you would apply to the Non-Domestic RHI. This can include small and large businesses, hospitals, schools, and organisations with district heating schemes where one heating system serves multiple homes.

The Domestic RHI

If the renewable heating system heats only a single property which is capable of getting a domestic , then you’d apply for the Domestic RHI. The EPC is the proof we need that your property is assessed as a domestic dwelling. Without one, you can’t join the scheme.
