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

 

Current legislation 2017:

  • 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 metering is mandatory;
  • If the system has a back up boiler, (i.e. is bivalent), then metering is mandatory;
  • 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.

 

Proposed legislation changes 2018:

  • Mandatory electrical metering is proposed.

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

 

Current legislation:

  • Property must be able to obtain a domestic EPC;
  • Heat pump is located in the domestic property;
  • 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 metering is mandatory;
  • If the system has a back up boiler, (i.e. is bivalent), then metering is mandatory;
  • 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.

Proposed legislation changes 2018:

  • Mandatory electrical metering is proposed.

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

 

Current legislation:

  • Property must be able to obtain a domestic EPC;
  • Heat pump is located in the domestic property;
  • 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 metering is mandatory;
  • If the system has a back up boiler, (i.e. is bivalent), then metering is mandatory;
  • 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.
  • 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.

Proposed legislation changes 2018:

  • Mandatory electrical metering is proposed.

Non-Domestic RHI Scenarios

4) Multiple domestic properties on a shared ground array

 

Current legislation:

  • Heat pumps located within the domestic property;
  • Installation needs to be MCS compliant (below 45kW);
  • Individual heat pumps need to be metered (heat and electricity);
  • Payments calculated on meter readings;
  • Payment will be to one authorised applicant representing the ‘owner’ of the system.

Proposed legislation changes 2018:

  • 30,000kWh limit applies to each property;
  • Heat meters will not be required;
  • Payments to be calculated on EPC and deemed output.

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

 

Current legislation:

  • Installation needs to be MCS compliant (below 45kW);
  • Individual heat pumps need to be metered (heat and electricity);
  • 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.

Proposed legislation changes 2018:

  • 30,000kWh limit applies to each domestic property;
  • For domestic properties, payments calculated on EPC and deemed output;
  • Usage for the commercial building will need to be metered.

6) Single domestic and single commercial properties on a shared ground array

 

Current legislation:

  • 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.

Proposed changes to legislation 2018:

  • 30,000kWh limit applies to the domestic property;
  • For domestic properties, payments calculated on EPC and deemed output;
  • 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.

7) Domestic property with integrated swimming pool and a commercial property on shared ground array

 

Current legislation:

  • 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.

Proposed legislation changes 2018:

  • 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;
  • For domestic properties, payments calculated on EPC and deemed output;
  • 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.

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

 

Current legislation

  • EPC will have to be obtained for the dwelling only, and only that part would be eligible for the Domestic RHI;
  • 30,000kWh limit applies to the domestic property;
  • For domestic properties, payments calculated on EPC and deemed output.

Proposed legislation changes 2018:

  • 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.
