Non-Domestic RHI scheme closure – 2 months to go!

The Non-Domestic RHI scheme (NDRHI) will be officially closed for applications in 2 months’ time. With the final deadline just around the corner, Ofgem reminds all prospective applicants to submit their application to the scheme by midnight on 31 March 2023.

Ofgem recently held a webinar where the NDRHI team explained the application process, how to submit a properly made application and how to avoid common application pitfalls. If you were not able to attend the event and like a copy of the slides, please get in touch with the Ofgem team at: Delivery&

Common application pitfalls and how to avoid them

According to Ofgem, below summarised are the 3 common application pitfalls and ways to avoid them:

  • Not providing planning evidence

Ofgem requires applicants to provide evidence from the relevant planning authority (usually your local council) that any necessary planning permission has been granted or is not required for your plant. If planning permission is required, this must be granted before your accreditation application is made.

Where planning permission is not required, you must provide a Lawful Development Certificate (“LDC”) or written correspondence from the planning authority which confirms that planning permission is not required for the plant. Evidence must clearly reference the location, capacity, and technology of the plant.

  • Not having meters calibrated correctly

If your heating system contains any inhibitor or antifreeze-containing glycol passing through the heat meter, then you must provide evidence to show that the meter has been suitably calibrated. This evidence should include the meter serial number, the name of the specific glycol product used, the correct percentage concentration of the glycol product and the date on which the calibration took place.

  • Not having suitable environmental permits

This criterion includes any water abstraction licenses, particularly for open-loop ground/water source heat pumps. Any necessary environmental permits should be in place prior to the submission of your application for accreditation and a copy of the permit must be included with your application.

If you have an open loop heat pump and are working within any abstraction limits, the Ofgem will require evidence that illustrates how your abstracted volume is maintained within these limits, including how your system is prevented from going beyond the relevant volumes. It is recommended to specify on an environmental agency application that you’re seeking accreditation to the Non-Domestic RHI scheme.
