The Non-Domestic RHI register will be unavailable from 5:00pm on Monday 16th July 2018 until Tuesday 17th July 2018 because of essential maintenance. During this time you can email RHI.enquiry@Ofgem.gov.uk and we will contact you as soon as possible.
New Regulations for the Non-Domestic RHI came into effect on 22 May 2018. See our website for further information about the new Regulations.
As a participant of the Non-Domestic RHI, we can pay you for up to 20 years as long as you continue to meet all the scheme’s requirements. This page explains what you need to do to stay compliant.
Monitoring and maintaining equipment
You need to:
- Maintain your equipment and periodically check all meters and steam measuring equipment for errors (see Meter reading and your responsibilities).
- Re-calibrate all meters and steam measuring equipment in line with manufacturer instructions (or not later than every 10 years).
- Keep a record of your maintenance schedule and retain service receipts.
- Ensure all meters and steam measuring equipment are located in accordance with any conditions of your accreditation.
Using appropriate fuel and retaining evidence of this
You need to:
- Demonstrate compliance with the sustainability requirements if you use biomass, biogas or produce biomethane for injection (see Easy Guide to Sustainability, Self-Reporting Guidance, Guidance Volume 2, Chapter 3).
- Keep fuel receipts.
- Log the quantity of fuel used (for biomass heating systems), or if harvesting from your own woodland, a log of deliveries made to the boiler house, including a record of where the harvesting has taken place (see our Guide to keeping fuel records for biomass).
- Store your fuel correctly.
Keeping us informed
You need to:
- Take meter readings and submit heat data every quarter (see Meter reading and your responsibilities). Note: If your installation is over 1 MWth, you need to record meter readings monthly, and submit them quarterly.
- Tell us about any significant changes to your installation or heat use.
- Submit an annual declaration confirming compliance with your ongoing obligations.
If you think you’re not complying with any of the above, or any other ongoing obligation, you must tell us within 28 days.
For further information, see Guidance Volume 2, Chapters 3-5.
Annual compliance declarations
Every year we’ll ask you to confirm a number of statements relating to you and your RHI installation, including that you continue to meet the eligibility criteria for the scheme and are complying with your responsibilities.
We’ll ask for this information by email (or by post if that’s how you applied). To sign an annual declaration, the Authorised Signatory will need to log into the RHI Register and select the Declarations link. You must respond within 28 days, or we may suspend your payments.
If you are self-reporting on the sustainability requirements, depending on your technology type and capacity, you may be required to submit an independent annual sustainability audit report. You can find further information in the Self-Reporting Guidance.
Keeping to the rules
It’s important you stay within the rules of the scheme. We can withhold payments if we believe you aren't complying or if your heating system was approved based on incorrect information. We'll inform you in writing of any investigation. If it confirms the non-compliance, we may impose sanctions which can include suspending payments, recovering overpayments, and/or revoking accreditation under the scheme.
