Consultation Announcement: New Biomass Maintenance Standard to cover planned and preventative maintenance of Biomass Appliances

MCS have today published a 2-week consultation on a new Biomass Maintenance Standard (MCS 040). This new standard describes the ‘Requirements for Maintenance Engineers carrying out Maintenance Activities’ associated with biomass appliances.

The development of this new standard is in response to a request from the Department for Business, Energy & Industrial Strategy (BEIS), and has been developed via a working group that MCS has assembled from across industry.

Subject to planned changes to legislation, the new standard will likely apply to all participants in the Renewable Heat Incentive (RHI) scheme.

Why is a standard needed?

A requirement for a ‘Biomass Maintenance Standard’ linked to RHI, was first suggested in the 2018 BEIS Urban Biomass consultation. The primary aim of this new standard is for the maintenance of air quality in terms of the emissions from biomass appliances. Poorly maintained appliances are known to emit particulates that damage air quality. The BEIS research paper delivered by KIWA and published in 2019 into the ‘measurement of the in-situ performance of solid biomass boilers’, identified a lack of operator knowledge and boiler maintenance as the primary reasons for poor Biomass Boiler operation and associated emissions.

What is covered in the new standard?

The new standard incorporates a criteria by which maintenance businesses who provide planned and preventative maintenance (PPM) should operate. It also includes the requirements associated with routine interim maintenance and the maintenance of connected heating system and components.

This standard will apply to a broad range of biomass appliance types and output capacities. This recognises that the services provided by maintenance engineers typically sit within a specific range of competence. For example, maintenance services can be limited by model of appliance or manufacturer or be limited by installation size and its complexity. Installation size and complexity can range from domestic and smaller non-domestic installations (<200kW), to medium (200kW to 1,000kW) and large (1,000+ kW) non-domestic.

MCS is inviting comments from all stakeholders. The deadline for submitting comments for this consultation is 1.00pm on Tuesday 4th May 2021.
