Non-Domestic Renewable Heat Incentive

Non-Domestic RHI: Up Close

The Non-Domestic RHI pays a quarterly income for 20 years for installations of ground source heat pumps in commercial buildings or new build or retrofit homes which feature Kensa’s micro ground source heat network.

What is the Non-Domestic RHI?

The purpose of the Non-Domestic Renewable Heat Incentive (RHI) is to compensate for the cost of installing ground source heat pumps in commercial applications, providing a long term rate of return and fast payback for business owners, developers and social housing providers.

Also referred to as the Commercial RHI, the Non-Domestic Renewable Heat Incentive (RHI) is a UK Government financial support scheme for renewable heat, targeted at, but not limited to, off gas grid commercial properties. Providing a unique opportunity for new build and retrofit installations, in addition to commercial applications the Non-Domestic Renewable Heat Incentive (RHI) can be used in domestic cases where district heating is utilised.

The Non-Domestic Renewable Heat Incentive (RHI) is the responsibility of the Department for Business, Energy & Industrial Strategy (BEIS) and is administered by Ofgem.

Who gets the Non-Domestic RHI?

  • The Non-Domestic RHI scheme covers England, Wales and Scotland;
  • Sectors eligible for the non-Domestic RHI include: commercial; social housing; house building; industrial; public; and not-for-profit;
  • Domestic micro heat network schemes, also known as district heating schemes, qualify for the Non-Domestic RHI;
  • A Non-Domestic installation might be a large-scale industrial heating system or a smaller community heating project;
  • The Non-Domestic RHI may be used to support both new build and retro-fit applications.

How much can I get through the Non-Domestic RHI?


The financial support will be paid every quarter at a set rate per unit of renewable heat produced (kilowatt hour or kWh), for twenty years, to the owner of the heating system.

Current tariff levels: 8.8p/kWh on the first 1314 hours of eligible energy produced followed by 2.6p/kWh on any additional heat produced
Calculating the non-Domestic RHI


Ofgem is responsible for publishing quarterly tariff tables showing the tariffs that will be applicable for each tariff period following BEIS’s quarterly degression announcement;

Once in the scheme, the level of support an installation will receive is fixed and adjusted annually with inflation. However, as with feed in tariffs, we expect the levels of support available for new entrants to the RHI scheme to decrease over time as the costs of the equipment and installation reduce through economies of scale.


You are paid a certain amount per kilowatt hour (kWhth) and calculations are made according to whether your system is designated “simple” or “complex”, or for applications submitted from 24 September 2013, ‘standard’ or ‘multiple’.

Am I Non Domestic RHI or Domestic RHI?

Where a ground source heat pump provides heat to a property which is used for business uses and pays business rates you should be able to receive the Non Domestic Renewable Heat Incentive (RHI), accessing 20 years of quarterly payments based on the metered heat usage.

However, if you do not pay business rates, or if your property holds a Domestic EPC, you will not be eligible for the Non Domestic RHI as your property fits the criteria for the Domestic RHI, which instead provides quarterly payments over 7 years.
