  • BUS

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 taken from the MCS certified product directory, where they also meet the standards required by BUS. 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 standards have been updated, the relevant standards at the time of commissioning will be used to assess eligibility.

Installing a product listed on the PEL does not guarantee that all requirements are met. Installers are responsible for making sure installations meet the BUS eligibility requirements.

The PEL does not consider SCOP of heat pumps. Installers need to calculate this separately.

In order to be listed on the PEL, MCS certified biomass boilers also require an emissions certificate meeting the scheme requirements.

For MCS certified biomass boilers that are not on the PEL, an eligible emissions certificate will be required to be submitted as part of a voucher redemption process. If we are satisfied it meets the requirements we will update the PEL.
