Renewable heat incentive (RHI)

The RHI, which applies to Great Britain, is a government scheme that provides financial incentives to increase the uptake of renewable heat and biomethane. These financial incentives are provided to help remove some of the barriers to adoption, such as high up-front costs and operational expenditure.

The RHI scheme was split into two phases:

1. •

   phase 1, which was introduced in November 2011 for non-domestic installations in the industrial, business and public sectors. The non-domestic RHI closed to new applicants on 31 March 2021

2. •

   phase 2, for the domestic RHI (previously covered by the Renewable Heat Premium Payment), which was rolled out in April 2014. The domestic RHI closed to new applicants on 31 March 2022

Although each of the non-domestic and domestic RHI schemes have now closed to new applicants, those accredited prior to closure may still be in receipt of payments under the scheme.

The non-domestic RHI was originally put in place pursuant to the Renewable Heat Incentive Scheme Regulations 2011 (2011 Regulations), SI 2011/2860. However, on 22 May 2018 the 2011 Regulations were revoked
