Renewable Heat Incentive - Eligible heat criteria for ground source heating and cooling systems

Scheme name

Non-Domestic RHI

The following document applies to ground source heat pumps with a commissioning date between 15th July 2009 – 4th December 2013 that are using heat other than heat that naturally occurs in the ground.

Under the RHI Regulations 2011, tariff payments for ground source heat pumps (GSHPs) can be made only for extracted heat that naturally occurs in the ground. As a consequence, heat that is injected into the ground and subsequently extracted by a ground source heating and cooling system is ineligible for support payments. 

Owners of accredited installations who proposed this method as part of their application are entitled to receive payments based on an agreed percentage (as described in this letter) of eligible heat for the duration of their participation in the RHI scheme.
