Which RHI is right for me?

The Renewable Heat Incentive (RHI) pays you for the renewable heat your ground source heat pump produces. With a ground source heat pump producing up to three times more energy than it consumes, the income you can receive through the RHI can be very rewarding. Use this section to identify the RHI stream your project qualifies for.

Domestic RHI Scenarios

1) Single domestic property on a single ground array

  • Property must be able to obtain a domestic EPC;
  • Payments based on EPC (payment made on the renewable part of the heating demand);
  • 30,000kWh heating demand limit applies;
  • Installation needs to be MCS compliant (below 45kW);
  • If the property is unoccupied for more than 183 days, then heat metering is mandatory;
  • If the system has a back up boiler, (i.e. is bivalent), then heat metering is mandatory;
  • Heat metered systems will be paid based upon their meter readings up to a maximum of the renewable part of the heating demand as detailed on the EPC;
  • Electrical metering is mandatory in all cases.

 

2) Single domestic property, plus outbuildings, on a single ground array

  • Heat pump is located in the domestic property;
  • Property must be able to obtain a domestic EPC;
  • Payments based on EPC (payment made on the renewable part of the heating demand);
  • Outbuilding not included in the EPC;
  • If the outbuilding has its own EPC, the system is classed as a centralised plant. This means that the Non Domestic RHI applies and metering is required (heating and electrical);
  • 30,000kWh heating demand limit applies;
  • Installation needs to be MCS compliant (below 45kW);
  • If the property is unoccupied for more than 183 days, then heat metering is mandatory;
  • If the system has a back up boiler, (i.e. is bivalent), then heat metering is mandatory;
  • Heat metered systems will be paid based upon their meter readings up to a maximum of the renewable part of the heating demand as detailed on the EPC;
  • Electrical metering is mandatory in all cases.

3) Single domestic property with integrated swimming pool building on a single ground array

  • Heat pump is located in the domestic property;
  • Property must be able to obtain a domestic EPC;
  • Payments to be calculated on EPC and deemed output;
  • 30,000kWh heating demand limit applies;
  • Installation needs to be MCS compliant (below 45kW);
  • If the property is unoccupied for more than 183 days, then heat metering is mandatory;
  • If the system has a back up boiler, (i.e. is bivalent), then heat metering is mandatory;
  • If integral to the building and included on the EPC, the swimming pool building will be included in the Domestic RHI. The heating of the swimming pool water will not. A separate building for the pool will not be included;
  • Electrical metering is mandatory in all cases.

Non-Domestic RHI Scenarios

4) Multiple domestic properties on a shared ground array

  • Heat pumps located within the domestic property;
  • Installation needs to be MCS compliant (below 45kW);
  • Individual heat pumps need to be metered (electricity);
  • Heat meters will not be required;
  • Payment will be to one authorised applicant representing the ‘owner’ of the system;
  • Payments to be calculated on EPC and deemed output;
  • Eligible for both retrofit and new build properties;
  • 30,000kWh limit applies to each property.

5) Single commercial property on a single ground array

 

  • Individual heat pumps will need to be metered (electrical and heat);
  • Payments calculated on heat meter readings;
  • Payment will be to one authorised applicant representing the ‘owner’ of the system;
  • Commercial premises need to be business rateable.

6) Multiple domestic and commercial properties on a shared ground array

  • Installation needs to be MCS compliant (below 45kW);
  • Individual heat pumps need to be metered (electricity);
  • Payment will be to one authorised applicant representing the ‘owner’ of the system;
  • Commercial premises need to be business rateable;
  • Commercial premises need their own entrance;
  • Commercial premises need to be heat metered and payments will be based on this for the commercial part;
  • 30,000kWh limit applies to the domestic property;
  • For domestic properties, payments calculated on EPC and deemed output.

7) Single domestic and single commercial properties with a centralised plant

  • Installation needs to be MCS compliant (below 45kW);
  • Mandatory heating and electrical metering required on centralised plant;
  • Commercial payments calculated on heat meter readings;
  • Payment will be to one authorised applicant representing the ‘owner’ of the system;
  • Any buried pipe on the heating distribution side joining buildings together must be RHI compliant (otherwise additional meters are required);
  • Commercial premises need to be business rateable;
  • Commercial premises need their own entrance;
  • This scenario will only be allowed under NDRHI if the domestic property comprises no more than 30-50% of the total heat load.

8) Domestic property with integrated swimming pool and a commercial property with centralised plant

  • Installation needs to be MCS compliant (below 45kW);
  • Mandatory heating and electrical metering required on centralised plant;
  • Payments calculated on meter readings;
  • Payment will be to one authorised applicant representing the ‘owner’ of the system;
  • Any buried pipe on the heating distribution side joining buildings together must be RHI compliant (otherwise additional meters are required);
  • Commercial premises need to be business rateable;
  • Commercial premises need their own entrance;
  • If the pool building is separate, the pool building heating is included, but not the pool water unless the pool is open to the public;
  • Proposed that this scenario will only be allowed under NDRHI if the domestic property is no more than 30-50% of the total heat load.

9) Commercial and domestic premises within the same building on a single ground array

 

Current legislation:

  • Only eligible for the Non Domestic RHI if the client owns the whole building;
  • If the domestic premises is owned separately, an EPC will have to be obtained for the dwelling only and only that part would be eligible for the Domestic RHI;
  • Installation needs to be MCS compliant (below 45kW);
  • Mandatory heating and electrical metering required on centralised plant;
  • Payments calculated on meter readings;
  • Payment will be to one authorised applicant representing the ‘owner’ of the system;
  • Commercial premises need to be business rateable;
  • Commercial premises need their own entrance;
  • 30,000kWh limit applies to the domestic property, if claiming only the Domestic RHI;
  • Proposed that this scenario will only be allowed under NDRHI if the domestic property is no more than 30-50% of the total heat load.

10) Individual flats in a tower block on a shared ground array

 

Current legislation:

  • Individual heat pumps in each property;
  • Electrical meters required on each heat pump;
  • Heat meters will not be required;
  • 30,000kWh limit applies to each domestic property;
  • For domestic properties, payments calculated on EPC and deemed output.
