Non-Domestic Renewable Heat Incentive (RHI)

The Non-Domestic RHI offers ongoing payments for 20 years for those installing renewable heat technology in the non-domestic sector

Cut carbon and get rewarded

The Non-Domestic Renewable Heat Incentive (RHI) was set up by the government to encourage UK businesses, public sector and non-profit organisations to make a positive change for people and the planet, by choosing renewable heat for their properties.

The Non-Domestic RHI offers quarterly payments over 20 years, with payments calculated based on the amount of renewable heat your system generates. Together, we can move away from fossil-fuel based heating systems and towards a more sustainable future.

The Non-Domestic RHI is available for businesses, public sector and non-profit organisations in England, Scotland and Wales. If the renewable heating system will be based on commercial, public or industrial premises, this is likely the scheme for you. Those eligible include large and small businesses, hospitals and schools.

If your renewable heating system only heats a single property which qualifies for a domestic Energy Performance Certificate, you’ll need to apply for the Domestic RHI.


The Non-Domestic RHI provides financial support for renewable heat technologies for 20 years, with payments made on a quarterly basis.

Once your application for the Non-Domestic RHI has been accepted, a tariff rate will be assigned to your installation based on its technology (e.g. whether it’s biomass, a heat pump, or solar heat) and its size. Payments will be made based on the actual heat output of the installation, and begin to accrue from the date of accreditation of the installation.

Tariff rates are set by the Department for Business, Energy and Industrial Strategy (BEIS). Visit the Ofgem website for more information.

There are a number of options eligible for the Non-Domestic RHI, including:

  • Solid biomass
  • Solar thermal
  • Geothermal
  • Biomethane
  • Biogas
  • Combined Heat and Power (CHP)
  • Ground source, water-source and air-source heat pumps – including a number of Daikin heat pumps



Eligibility criteria

To ensure you receive your payments as planned, you’ll need to meet certain criteria to ensure you’re eligible – and remain eligible – for Non-Domestic RHI payments.

  • Only the owner of the installation can apply for Non-Domestic RHI payments. Where there is more than one owner, you must receive written permission from any co-owners.
  • Your equipment must be used for an eligible heat use, such as space, water or process heating within a building.
  • If you choose a heat pump to serve your building, it should use a ‘liquid medium’ to heat your property – using traditional radiators, underfloor heating or heat convectors. Air-to-air heat pumps are not eligible for the Non-Domestic RHI.
  • You’ll need to follow metering guidance to ensure your payments are accurate.
  • Your heat pump must be certified under the Microgeneration Certification Scheme (MCS). All Daikin Altherma systems are MCS accredited and RHI-ready.

When you choose Daikin to supply and install your heat pump, you can rest assured that your heat pump exceeds the criteria you’ll need to meet to qualify for your Non-Domestic RHI payments.
