Non Domestic RHI Closure
The Non Domestic Renewable Heat Incentive (RHI) will close to new applicants on 31 March 2021. This means that projects which use an eligible renewable heat source must be commissioned and a full application made to Ofgem before this date.
However, there was a tranche of Tariff Guarantees that were released by Ofgem on 13 October 2020 which allows certain technologies to be fully commissioned until 31 March 2022.
|Tariff Guarantees||Energy Source/Technology|
|12||Solid Biomass Boiler|
|1||Solid Biomass CHP|
|70||Ground Source Heat Pump|
|14||Water Source Heat Pump|
|0||Shared Ground Loop*|
*There are no longer any Tariff Guarantees for these technologies
For an energy source that has a Tariff Guarantee available, a Stage 1 application must be made to Ofgem before 31 March 2021. Once a project has a Tariff Guarantee, it will have until 31 March 2022 to be commissioned and a full application to Ofgem submitted.
