New build and retrofit social housing properties featuring Kensa’s micro district heat network system are eligible for 20 years of guaranteed income from the Non Domestic RHI, and in addition may benefit from further support via the HCA and ECO grants.
The RHI, HCA, & ECO
The Non Domestic stream of the RHI is far more favorable and rewarding for retrofit social housing compared to the Domestic stream; the Domestic Renewable Heat Incentive (RHI) is structured in such a way that it fails to adequately support retrofit social housing, nor is it available to new builds.
A significant and unique opportunity therefore exists for new build and retrofit social housing schemes with the Non Domestic RHI; Kensa’s micro district ground source heat network solution offers the answer.
The Department for Business, Energy and Industrial Strategy (BEIS) has confirmed that Kensa’s innovative micro district ground source heat network design – where an individual ground source heat pump is installed inside each property and linked to a communal ground array – qualifies as a heat network system (district heating) and thus is eligible for the non domestic RHI.
All non domestic RHI payments are paid to the landlord or the entity deemed as the system owner; they are index-linked for twenty years. These payments are currently based upon meter readings although a recent RHI consultation proposes this changes to a deemed consumption figure; this refinement eliminates the cost of metering/communications equipment and also provides certainty about the payment levels.
In retrofit schemes, the solution also complies with the definitions of a heat network system under the Energy Company Obligation (ECO), which provides a capital subsidy towards the system investment costs, based upon the amount of CO2 savings made. Kensa has arrangements in place with several of the largest energy suppliers to provide ECO funding to social housing micro heat network housing schemes.Read more
Importantly, receiving an HCA grant for the building does not rule out also receiving RHI, providing:
- the correct accounting separation is in place and;
- the original HCA grant offer did not highlight any intent to use renewables.
Ofgem clearly states that RHI support will only be available for an eligible installation if no grant from public funds has been paid or will be paid in respect of any of the costs of purchasing or installing the eligible installation. This means it is vital to transparently separate the renewable heat installation costs from the house building costs towards which HCA grant is accounted.Download guidance

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.
