Biomass Suppliers List

Welcome to the Biomass Suppliers List (BSL) website. The BSL is administered by Gemserv on behalf of the Department for Business, Energy and Industrial Strategy (BEIS; formerly DECC). The BSL is a list of Renewable Heat Incentive (RHI) eligible woodfuels and biomass suppliers may register their woodfuels on the BSL.

The Department of Business, Energy and Industrial Strategy (BEIS), formerly DECC, is pleased to announce that, following a competitive tender process, the ongoing administration of the Biomass Suppliers List (BSL) will continue to be undertaken by Gemserv, in partnership with HETAS and Woodsure. This new phase of the BSL will see some changes to how the scheme operates, including:

  • Introduction of supplier fees for the BSL – From January 2017, all suppliers on the BSL will need to pay fees to cover the costs of running the scheme. More details on this are available here. Suppliers are invited to respond to a consultation on the proposed charging model available here, after reading the Consultation supporting document. Two workshops on this are being held on 19th and 24th August in London, please contact to book a place (note places are limited).
  • Set up of a BSL Advisory Panel – An Advisory Panel is being introduced comprised of various industry and self-supplier representatives, to ensure that the users of the BSL are able to input to the running of the scheme. Suppliers are invited to nominate themselves to be part of the Panel by submitting a Nomination Form to after reading through the BSL Advisory Panel Overview document and the Panel Terms of Reference.  


  • Due to a high level of demand to attend the workshops, an additional webinar session will be held on 31st August between 11am and 1pm. To register your interest please click here and register your interest by clicking on “Register” next to “Event Status” and filling in your details. You will receive a confirmation email upon registration which will include a link to the webinar event and an event password which you will need to use to sign into the webinar. Please ensure that you join the session around 10 minutes before the start, as some attendees may be required to download some software in order to access the webinar. Please note that due to an anticipated high number of attendees, all attendees will be muted during the session. However attendees will be able to either submit questions ahead of the session by emailing or by typing questions during the webinar itself. We will attempt to answer as many questions as possible during the session and any that we don’t manage to answer, we will follow up afterwards.


RHI participants using biomass fuel need to ensure that their fuel meets the RHI sustainability criteria and demonstrate this to Ofgem in order to claim RHI payments. Fuel must meet a lifecycle greenhouse gas (GHG) emissions criteria of 60 per cent GHG savings against the EU fossil fuel average, and the land criteria – which for woodfuel are set out in the 
UK Timber Standard for Heat and Electricity.  

Local suppliers with BSL authorised fuels can be searched by postcode through the  Find a Fuel site. On this site, those producing and trading woody biomass, as well as Self-Suppliers, can apply to register their fuels as meeting those requirements. Traders can also request that we list their fuels on our public-facing Find a Fuel site.

Please note that the BSL does not cover RHI payments - refer to Ofgem for any queries on domestic and non-domestic RHI payments and eligibility.

The BSL is a fuel sustainability scheme but encourages the use of high quality fuel. The BSL supports the use of fuel with quality assurance certification through Woodsure and ENplus. 

The helpdesk operates 10am-2pm Monday, Wednesday and Friday, except UK national holidays.

Important information regarding Land Criteria

Land Criteria sustainability requirements for the RHI came in effect on the 5th July 2015. In order for woodfuel(s) to become or to remain BSL authorised, it is essential that you read the Land Criteria information on the land criteria webpage and take steps to demonstrate your compliance. Any
authorised fuel that has not demonstrated compliance with the land criteria will now have its authorisation revoked.
