How do I apply for the Non-Domestic RHI?
Following installation, the system owner must make the application for the Non-Domestic RHI. If you need support, we offer assistance with RHI applications as part of our services, such as Kensa heat pump technical support.
When you are ready to apply, you must create an online account with the RHI’s provider, Ofgem. It’s important that you read Ofgem’s official guidance on how to apply for the Non-Domestic RHI to make sure you understand the process.
The documents you need before you apply
Before you apply, you will need documentation to qualify for the 20-year payments. This documentation includes:
• Proof of consent
Evidence of consent from the owner of the system, a board member or an authorised signatory to apply for the RHI.
• Bank account details
For example, both physical and online evidence of a bank statement which includes the account name, address, sort code and account number.
• Evidence of installation details
This includes the installer, date of installation, and the heat pump’s serial number. You must also provide receipts, invoices or the commissioning certificate and report, plus photographs of the installation clearly showing the serial number of the equipment.
If the heat pump is higher than 45kW and thus cannot be MCS approved, the installer must provide MCS-approved calculations of the heat pump’s SCoP and CoP.
• Evidence of non-domestic status
For instance, a commercial premise must provide council tax bills, business rates bills, or a letter of exemption from local council.
For projects featuring multiple domestic dwellings, photographic evidence can be taken of the dwelling from the outside to prove that it is a dwelling, and that it exists.
• Offer letters relating to grants paid for installation
And also any evidence of grants surrendered or repaid in full.
This is because Ofgem will not accept any application that has been doubly government funded. For instance, if biomass has been installed and claimed for at the same address under a previous government funding initiative, the ground source heat pump will not be eligible for the Non-Domestic RHI.
• Copy of meter manufacturer’s certification (if applicable)
For each model of meter, provide the manufacturer’s certification that the meter meets the class 2 standard and requirements. This must be supplied together with photographic evidence of the meters running, as well as photographic evidence of the meter reading supplied for the application.
These readings must be taken within 3 days of the application submission.
• Schematic diagram from the installer
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, which must be shown and labelled as wholly enclosed and permanent.
- The positions of any external electric meters, relevant hot water and/or steam meters and their associated components.
- A code key so that the schematic can be easily understood.
• Copy of manufacturer’s technical specifications
Evidence of the heat pump unit’s technical data to support declaration of its Coefficient of Performance (CoP). Kensa Heat Pumps will provide product technical information required to support the application.
• Proof for installations below 45kWth (solar thermal, heat pumps, solid biomass)
These installations must have proof of MCS or equivalent certificate.
• Proof for installations between 46 – 999KWth with ‘simple metering’
Provide suitable evidence to confirm the installation exists. For example, submission of scanned purchase invoices or orders, commissioning reports or similar evidence which contains relevant details regarding the application.
Remember that a heat pump higher than 45kW cannot be MCS certificated. For that reason, MCS- approved calculations must be provided to show that the SCoP and CoP of the heat pump are up to standard. Kensa can supply these.
