The Ofgem Product Eligibility List (PEL) is an administrative tool that makes it easier to identify products that could be eligible for the BUS. All products on the Ofgem PEL are extracted from the MCS certified product directory, where they also meet the MCS standards required by BUS. The MCS standards required by BUS are approved by Secretary of State as set out under the BUS regulations.
The PEL only identifies products that meet the MCS standards and, in the case of biomass boiler boilers, have an eligible emissions certificate. There are many other eligibility requirements under BUS, including technology specific technical requirements, and the PEL does not ensure compliance with these requirements. All BUS eligibility requirements are outlined in the BUS regulations and Ofgem’s guidance.
Installers are responsible for making sure installations meet these eligibility requirements and must not rely on the PEL alone. There may be cases where a product is on the PEL, due to meeting the MCS standards requirement, but ineligible for BUS for a different reason. Where this is the case, we will reject the application.
The PEL does not consider SCOP of heat pumps. Installers need to calculate this separately. The Ofgem PEL is not exhaustive – there may be some products on the MCS certified product directory that do meet the requirements for BUS but are not on the Ofgem PEL.
Where MCS standards as approved by BEIS have been updated, the relevant standards at the time of commissioning will be used to assess eligibility.
In order to be listed on the PEL, MCS certified biomass boilers also require an emissions certificate meeting the scheme air quality requirements. For MCS certified biomass boilers that are not on the PEL due to a missing emissions certificate, an eligible emissions certificate will be required to be submitted as part of a voucher redemption process. If we are satisfied it meets the MCS requirements and the emissions certificate requirements we will update the PEL.
