Beginning the process

Ofgem offers guidance on how to apply for the Non Domestic Renewable Heat Incentive (RHI) for your commercial or district ground source heat pump system.

To apply for the Non-Domestic RHI the applicant needs to create an on-line account at https://rhi.ofgem.gov.uk.

In order to open an account the applicant will need proof that the bank account provided is held in the name of the organisation/company, for example a photocopy of a bank statement which shows the account name, address, sort code and account number with financial information blackened out.

The applicant will then be sent an email confirming that the account has been created, and a link that will need to be clicked on to change the password. After this is complete, the applicant will be able to start to complete the application.

Ofgem has created a number of helpful guides to advise on the application provess: https://www.ofgem.gov.uk/environmental-programmes/non-domestic-renewable-heat-incentive-rhi/how-apply-non-domestic-rhi

Information required

1) Evidence of consent from the organisation to apply for the Non-Domestic RHI.

2) For each plant or communal system, evidence showing installer details, date of installation, and serial number. This could be any one (or a combination) of the following:

  • Receipts and/or invoices relating to the installation of the equipment;
  • Commissioning certificate;
  • Commissioning report;
  • Photograph of the installation clearly showing the serial number of the equipment.

3) Evidence of non-single domestic status (e.g. multiple council tax bills, business rates bill, letter of exemption from local council).

4) Documents such as offer letters relating to grants paid in respect to the installation, and any documentary evidence of grants surrendered or repaid in full.

5) For each model of meter, a copy of the manufacturer’s certification or equivalent that the meter meets the Class 2 standard and requirements as set out in the Guidance

6) A schematic diagram meeting the requirements as set out in the Guidance. This must include the following:

  • All plants providing heat to the heating system, whether eligible or ineligible
  • All uses supplied with heat from the heating system, both eligible and ineligible.
  • The pipework connections between all plants and heat uses.
  • An indication of building boundaries and names/types
  • The positions of relevant hot water and steam meters and their associated components.
  • This is likely to require a key to allow the schematic to be fully and easily understood.

7) Installations below 45kWth (solar thermal, heat pumps, solid biomass):

  • MCS or equivalent certificate;

8) Installations of 46 – 999KWth with ‘simple’ metering:

  • If these conditions apply, please supply suitable evidence to confirm the installation exists. For example, submission of scanned purchase invoices/orders, commissioning reports/certificates or similar evidence which contains relevant details regarding the application.

9) Heat pumps:

Evidence e.g. a copy of the manufacturer’s technical specification for the heat pump unit to support declaration of the heat pump’s COP.

Summary of ‘further information’ required during application

Where indicated during the online review process, under question “HK120”, where the question reads: “Please provide a brief description of your installation, including the make & model of the main components. For further details of the information that should be included here, please refer to the guidance.”

All Installations

If you have had prior interactions with Ofgem regarding this installation, please provide any supplementary information as requested by Ofgem.

Heat Pumps

Please state the design conditions for the ground source heat pump installation (both source and sink temperatures in °C). Ofgem require these to verify the Coefficient of Performance (COP) figure stated stated in the application.
