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 BSL helpdesk now operates 10am-2pm Monday to Friday, except UK national holidays.

The BSL will shortly be launching a new system, with a number of new features. As part of this new system, suppliers with multiple accounts for different supplier types will now be able to group these accounts under one master account. For instance, if a supplier has both a Producer account and a Trader account, these can now be managed under one email address, one login and one account.

To group multiple accounts together, please send an email from the primary email address of each account that you want to merge together to In each email you should state which email address you wish to have as the primary login and a reference number for an application registered to the account. Once this account has been created, you will be able to add additional email addresses that can have access to the account (i.e. if you are an organisation with multiple users). 

Suppliers will also be able to change the primary email address on their BSL account. To do this, please email from the primary email address confirming the new email address you would like to use and a reference number for an application registered to the account. Where it is not possible to send an email from the current primary email address, we ask that you provide signed confirmation from a named Director on the account to approve this change.


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.

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.
