Before you start
To complete the application form for the Domestic RHI, you’ll need:
- Your certificate number
- Your number
- Your bank details so that we can pay you. Make sure that the name and personal details you use for your application are the same as on your bank account.
- Your metering questions, if you need to be metered
Invoices or records stating both the cost of the system and labour to install (these can be approximations and will not affect your payments or eligibility).
Depending on circumstances, we may need to review your application. See the ‘Once submitted’ tab for further information.
For full information about the Domestic RHI, see all of our Essential Guides.
A few things to note
The application form will work on all devices but we recommend you use your computer (rather than a smartphone or tablet) where possible.
We ask that the applicant completes the form personally as bank and personal details are required. If it’s difficult for you to complete an online application because you have a disability or you don’t have easy access to a computer, please contact our applicant support centre for help.
Please see our full terms and conditions in the Publications and Updates below.
Green Homes Grant
The Green Homes Grant (GHG) is a government grant in England to assist homeowners with energy-efficient and low-carbon heating home improvements. This is not administered by Ofgem, but measures under this grant may interact with our existing schemes. For further information on eligibility and how to apply, please visit the guidance published by the Department for Business, Energy and Industrial Strategy. The Simple Energy Advice website also provides information on the scheme.
You can claim both the Domestic RHI and the GHG for renewable heat installations. You must claim the GHG first and then notify us the amount of the voucher that you have used when you apply for accreditation to the Domestic RHI. The GHG amount will then be deducted as appropriate from your Domestic RHI payments.
What to expect from your installer
We ask that the applicant completes the form personally. However, your installer may help you gather much of the information you need to apply and stay compliant with the scheme rules.
Your installer should give you:
- an MCS certificate (within 10 working days of the commissioning date)
- an MCS compliance certificate (and they should point out where the MCS installation number is on it)
- an itemised invoice showing parts and labour
- the completed Installer Metering Questions (for biomass or for heat pumps) document (only if your heating system needs to be metered). You will need this to complete the questions on metering in the application form. Also, there's an Alternative Metering Arrangements (for biomass or for heat pumps) document that your installer will give you if required.
- advice on the heating system’s maintenance, servicing and efficient use. This is because you must keep your heating system in good working order throughout your seven years on the scheme. They should also explain what actions might invalidate the warranty.
- advice on how to use and read your meters (if you need them).
Once you’ve submitted your application, we’ll tell you if it has been accepted, rejected or placed in review.
Our application systems are automated and conduct checks to verify your identity based on the information you submit using a third party provider. In some cases, we may need more information before we can decide if your application is eligible and we will request this on a case by case basis.
If your application is placed into review, a member of our team will contact you within five working days to inform you of this, and explain the reason(s) why. Please note that a random selection of all applications are put into review for quality assurance purposes also. For more detailed information, see our Helpsheet: What to do if your application is in review.
