Eligibility & Tariff Levels for the RHI

The Renewable Heat Incentive (RHI) tariff is available to anyone who installs a renewable heating product, as long as they meet the eligibility criteria set out by the Government. 

Am I eligible to take part in the RHI?

The Renewable Heat Incentive (RHI) is open to both domestic and commercial adopters of green heat technologies including air source heat pumps and ground source heat pumps. So that means businesses, farmers, hospitals and schools will all be eligible for the RHI tariff. The domestic RHI is open to homeowners, social and private landlords and homeowners who self-build.

What is a renewable heat system?

Installing heat pumps and other types of renewable heat technologies allows a property to generate heat and hot water from renewable sources of energy such as the sun and the air.

Technologies which are eligible for the RHI include:

  • Solar thermal systems (solar hot water)
  • Air source heat pumps (air-to-water)
  • Ground source heat pumps
  • Biomass boilers

What if I already have a renewable heating system?

Legacy installations are eligible for the RHI, as long as the renewable heat product has been installed since July 15, 2009.

Tariff Levels

RHI payments are to be made quarterly over seven years, with the tariff levels for the domestic RHI to be as follows:



Solar thermal panels (flat plate and evacuated tube)
