What is an IRMA?

The Independent Report on Metering Arrangements (IRMA) is intended to verify to Ofgem that an installation seeking accreditation to the Renewable Heat Incentive (RHI) has metering arrangements in place which meet the RHI eligibility requirements, in accordance with the RHI Regulations.  The Report will cover the installation’s metering arrangements for RHI purposes, including: 

  • Whether meters and sensors are correctly positioned;

  • Whether meters and sensors are installed in accordance with the manufacturer’s instructions;

  • Whether the schematic diagram is an accurate representation of the installation and the heating system of which it forms part.

Aardvark Certification’s staff are fully trained and qualified to produce an Independent Report on Metering Arrangements (IRMA). We have prepared many such reports for our clients in the Biomass and Anaerobic Digestion (AD) sectors. We are independent, impartial and trusted and have the necessary expertise and experience to assist with your IRMA requirements. We are also well aware of the quarterly rush which ensues following RHI degression announcements and can ensure that sufficient resource is dedicated to producing your IRMA in a professional and timely manner.

When is an IRMA Required?

Where an installation can be classified as falling into one or more of the following scenarios, Ofgem will require a report for an installation which:

  • has a capacity of 1MWth or above; or

  • is classed as having a ‘multiple’ metering arrangement for RHI payment purposes; or

  • uses steam as the heat transfer medium

  • where additional RHI capacitytakes an accredited installation’s capacity over 1MWth;

  • where additional RHI capacity takes an accredited installation’s capacity over 45kWth and the installation is considered to have a ‘multiple’ metering arrangement for RHI payment purposes; or

  • where a change is made to the installation/heating system that results in an RHI-accredited installation moving from a standard to multiple metering arrangement classification for RHI payment purposes
