Resource hub Funding Watch Renewable Heat Incentive (RHI) The Non-Domestic Renewable Heat Incentive (RHI) is a government environmental programme that provides financial incentives to increase the uptake of renewable heat by businesses, the public sector and non-profit organisations. Once you’re accredited, a tariff level will be assigned to your installation based on its technology (eg biomass, heat pump, solar) and size. Payments will be made based on the actual heat output of the installation. Tariff rates are set by the Department for Business, Energy and Industrial Strategy (BEIS). Find out more.
