What is the HETAS Approved Biomass Maintenance Scheme?

The Scheme sets an accredited standard for the servicing and maintenance of Non-Domestic RHI eligible biomass boilers. In 2019 BEIS commissioned research led by KIWA to evaluate the performance of biomass boilers in situ. This independent research conclusively proved that biomass boiler efficiency could be increased, and harmful emissions reduced. It recommended that an annual service, at a minimum, by an accredited business could help to improve biomass boiler performance and reduce harmful emissions.

The biomass industry, with the support of Micro Certification Scheme (MCS) and HETAS, consulted and created a Standard (MCS040), which details criteria for businesses conducting Planned and Preventative Maintenance (PPM) of biomass boilers to adhere to. HETAS was appointed to administer the Scheme. Only businesses achieving this Standard gain accreditation. As well as increasing the efficiency of the boiler and reducing the levels of emissions, the Scheme also provides assurance for RHI recipients that their boilers have been serviced to the right standard by fully qualified engineers who intimately understand the workings of the biomass boiler.


When does the Scheme come into force and is compliance a legal requirement?

Implementation of the regulations became effective in April 2022. Ofgem will start mandating evidence from you in April 2023, however, Ofgem could request this evidence at any time since the introduction of the scheme. Compliance is not a legal requirement, but if you are unable to provide evidence of an annual service conducted by an accredited business then you will not qualify for RHI payments going forwards.
