Changes to the Non-Domestic RHI
The government regularly reviews policy, which means the rules can change for both existing and new participants. To join the scheme and keep receiving your payments, it’s important you keep up to date with the scheme rules.
We’ll publish information about policy changes in this section, the content and timing of which will be subject to parliamentary process.
Our updates are based on information provided by the Department for Business, Energy and Industrial Strategy (BEIS).
Non-Domestic RHI closure
The Non-Domestic Renewable Heat Incentive Scheme (NDRHI) in Great Britain closed to new applicants on 31 March 2021. There are some circumstances under which an application for accreditation or registration can be made post-scheme closure, including those that have been granted an extension application or have a Tariff Guarantee extended commission date. For more information on the closure please go to our Non-Domestic RHI Closure page.
