The Renewable Heat Incentive has two schemes - Domestic and Non-Domestic. They have separate tariffs, joining conditions, rules and application processes. Depending on a number of factors about your project will determine which scheme you will be able to apply for.


The Domestic Renewable Heat Incentive (Domestic RHI) is a government financial incentive to promote the use of renewable heat. Switching to heating systems that use eligible energy sources can help the UK reduce its carbon emissions and meet its renewable energy targets. Payments under the Domestic RHI are paid quarterly over a 7 year period and are normally estimated or deemed based on the heat demand of the energy performance certificate EPC of the property. We have provided a link to the Ofgem Domestic RHI calculator at the top of this page should you want to find an estimate to what you may receive from the scheme.

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. Eligible installations receive quarterly payments over 20 years based on the amount of heat generated.

All Non-Domestic Heat Pump installations will require to be metered for payment based on the renewble amount of heat produced from the heat pump. In this instance it is diffucult to predict how much you will receive in payment from the non-domestic RHI. However, for all domestic RHI installations, we will issue a full estimated system performance to estimate your running cost and RHI payments you will expect to receive.
