Biomass Boilers and the Non-Domestic Renewable Heat Incentive – How does the UK leaving the EU affect me? Many businesses, non-profit organisations and the public sector took advantage of the Renewable Heat Incentive (NDRHI) put in place by government. The initial scheme was created by the European Council to increase the use of renewable energy across member countries. It is administered by Ofgem who work alongside BEIS. Whilst Ofgem are no longer accepting applications for new systems following the deadline of 31 March 2021, there are still many existing systems in place and many applications awaiting processing due to delays caused by COVID 19.
