Renewable Heat Incentive

Following the success of the feed-in tariff, the renewable heat incentive was developed to support renewable energy technologies which generate heat.  The technologies covered include:


  • Biomass Boilers
  • Air Source Heat Pumps
  • Ground Source Heat Pumps
  • Solar Thermal panels

There are Domestic and Non-Domestic versions of the renewable heat incentive.

Domestic RHI

  • For domestic properties
  • Pays higher tariffs but only over a period of 7 years
  • Payments for biomass boilers and heat pumps are calculated using the heat demand from the Energy Performance Certificate for the building
  • A Green Deal Assessment is required to receive the Domestic RHI

Non Domestic RHI

  • For commercial properties or where more than one domestic property is connected to a district heating system.
  • Pays lower tariffs, but for a period of 20 years
  • Payments are based on the actual heat output of the system as measured by a heat meter

The latest tariffs can be viewed on the OFGEM website.  Once on the scheme, the tariff will increase with inflation.
