On 1 January 2019, the Department for Business, Energy and Industrial Strategy (BEIS) announced that it would reduce the tariff price level (through a process called degression) for large biogas and biomethane installations on its non-domestic Renewable Heat Incentive (RHI) scheme.
The Non-domestic RHI opened on 28 November 2011 as a UK Government financial incentive scheme to promote the generation and use of renewable heat by non-domestic users. Unlike most low-carbon incentives, it is funded directly by Treasury, not energy suppliers.
