Product Eligibility List PEL
The Product Eligibility List (PEL) is effectively a spreadsheet updated by Ofgem in September 2023. It shows the makes and models of renewable heating products which we have assessed as eligible for the scheme based on information supplied by the Microgeneration Certification Scheme (MCS).
The Microgeneration Certification Scheme MCS forms a key element of the Government Boiler Upgrade Scheme (BUS), and other funding mechanisms, requiring installers to be certified by the scheme and also to use products recognised by MCS via the Product Eligibility List (PEL) issued by Ofgem.
The Product Eligibility List (PEL) is a shorter list than the MCS products lists as it lists products that meet MCS standards, but are specifically air, ground and water source heat pumps as well as biomass boilers, recognised under the BUS. There are currently just under 3,000 products covering these areas, all of which are recognised by the current Boiler Upgrade Scheme.
In September 2023 the MCS website contained just over 4,000 MCS qualified installers and just over 65,000 products. The search function of the website to find products can be found here https://mcscertified.com/product-directory/
Some of the financial incentives that were on offer by the government, (previously the Feed-In tariff and the Renewable Heat Incentive -now closed) and the Boiler Upgrade Scheme (BUS) require confirmation of accreditation to the Microgeneration Certification Scheme by product and installer, as well as requiring an up to date EPC.
To search through the products available and recognised by the boiler upgrade scheme an downloadable excel can be found here https://www.ofgem.gov.uk/publications/boiler-upgrade-scheme-product-eligibility
