Non Domestic RHI
This scheme support heat pump installations for non-domestic properties and multiple domestic properties. Tariffs are lower than in the domestic scheme, but they are paid over 20 years and they are un-capped.
Installations for two or more or more dwellings can be eligible for non-domestic RHI provided they are separate legal entities. In case there is more than one dwelling in the same estate, the dwellings are considered separate if they are treated as separate from a council tax banding point of view.
If two or more dwellings are connected to one heat pump system, payments are based on meter reading from a heat meter.
If two or more dwellings share the same ground loop and have separate heat pumps in each dwelling, the heat production is deemed based on the estimate heat requirement in the EPC.
Tariff payments over 20 years in many cases equates to 2-3 times the initial cost for the heat pump system.

How much these rates represent in real terms will vary between householders and heating technologies. In order to know how much you could potentially earn, you will need to know how much heat your system will generate in a year, in kWh:
To help improve the performance of renewable heating systems, there will be an extra incentive for applicants who install metering and monitoring service packages, of £230 per year for heat pumps.
