Domestic RHI Grant

The Domestic Renewable Heat Incentive (RHI) grant scheme was launched by the UK government in April 2014. Replacing the previous grant schemes, the RHI is designed to provide a financial incentive to homeowners for installing renewable heating technologies.

Grant eligibility

In order for renewable systems to be effective, the building must achieve a certain level of insulation and the heating system should be designed around their use as a primary source of heating.

An Energy Performance Certificate (EPC) for the building is required to assess it's suitability. This can be produced from the SAP report for a new build or by a Green Deal Assessment of an existing building.

If you live in an older property, eligibility can often be achieved by increasing insulation levels throughout to allow a renewable heating system to operate efficiently.
