The Biomass Suppliers List (BSL) was introduced by the Department for Business, Energy and Industrial Strategy (BEIS), formerly the Department of Energy and Climate Change (DECC), in April 2014.
It supports the Government's Renewable Heat Incentive (RHI) scheme by ensuring that RHI payments are only issued to biomass boilers using woodfuel that meets certain sustainability and legality requirements.
The tabs on the left hand side provide further information on the scheme and these eligibility requirements. Fuel quality is not specifically assessed as part of the BSL process, however information on dedicated fuel quality schemes can be found under the Fuel Quality tab.
The BSL is administered on behalf of BEIS by Gemserv, supported by our technical partners Woodsure and HETAS.
What is the BSL?
The Biomass Suppliers List (BSL) is a list of Renewable Heat Incentive (RHI) eligible woodfuels. Fuel types registered on the BSL include: logs; woodchip; wood pellets; and wood briquettes.
The aim of the BSL is to provide RHI participants with a simple way to demonstrate that their fuel complies with the RHI Sustainability Criteria for woodfuel.
The RHI Sustainability Criteria focuses on two elements: sustainability and legality.
To register their fuel on the BSL, biomass suppliers must demonstrate that their woodfuel is at least 60% less carbon intensive than the average EU fossil fuel equivalent and that it meets the UK Timber Standard for Heat and Electricity's definition of legal and sustainable woodfuel. More information on these requirements can be found under the Sustainability Criteria tab.
The BSL is NOT a mark of fuel quality. RHI participants wishing to source fuel that meets a certain quality should refer to dedicated fuel quality schemes such as Woodsure and ENplus. More information on these schemes can be found under the Fuel Quality tab.
To claim Renewable Heat Incentive (RHI) payments, participants must demonstrate that their fuel meets the RHI sustainability criteria of greenhouse gas emissions and land criteria.
Greenhouse gas emissions
Suppliers must demonstrate that the greenhouse gas emissions generated from the cultivation, processing and transport of their biomass fuel are at least 60% lower than the EU fossil fuel average for heat, when used in a boiler which achieves an average of 70% seasonal efficiency. The emissions limit is ≤34.8g CO2 per MJ. This figure is calculated using the life cycle assessment methodology set out in the European Commission's 2010 report.
To calculate their greenhouse gas emissions, suppliers must use either the simple calculator within the BSL application process or the more comprehensive B2C2 calculator, which can be accessed via this link. Information provided during the application process will determine which calculator must be used.
Producers, Traders and Producer-Traders of virgin or virgin/waste blend woodfuel are also required to demonstrate compliance with the land criteria requirements. This confirms that the wood has been legally felled and that the woodland has been sustainably managed. Self-Suppliers and waste fuels (as per the BSL definition of waste) are exempt from Land Criteria.
Full details on the Land Criteria requirements can be found in our guidance document under the Documents and Guidance tab.
There are two categories of land criteria compliance:
Category A evidence
If you are able to demonstrate that 100% of your fuel is FSC or PEFC certified, then you fall under Category A.
- FSC certificates must be held in your name or you must be a listed group member / site on the FSC database.
- PEFC certificates must be held in your name or you must be listed as a participant in Group Certification FM on the PEFC database.
If your FSC or PEFC certificates do not cover 100% of your fuel, are for Controlled Wood and/or are not in your name, you fall under Category B.
Category B evidence
There are three ways of demonstrating compliance under Category B:
1. Felling licence and woodland management plan - this is for suppliers who have 100% of their fuel covered by both a felling licence and a UK Forestry Standard compliant woodland management plan. 100% of the raw materials being used must have been sourced from the UK.
2. Risk Based Regional Assessment (RBRA) - this is for suppliers sourcing 100% of their fuel from within the UK but who do not have a felling licence and woodland management plan for 100% of their fuel. An RBRA is a declaration of materials purchased within the UK for the previous calendar year. A UK RBRA template can be downloaded from the Documents and Guidance tab.
3. Bespoke Risk Based Regional Assessment (RBRA) - this is for suppliers who are sourcing some or all of their fuel from outside of the UK and cannot provide Category A evidence. Further information on this option can be found in our guidance document under the Documents and Guidance tab.
The fuels listed on the Biomass Suppliers List (BSL) have been authorised because they meet the sustainability and legality requirements of the Renewable Heat Incentive (RHI) scheme. BSL fuels are NOT assessed for fuel quality as this is not a core requirement of the RHI.
However, we appreciate that RHI participants may wish to buy fuel that meets certain fuel quality standards. To support this, biomass suppliers are able to inform the BSL if their fuel is registered with two recognised fuel quality schemes, Woodsure and ENplus. RHI participants are then able to use these as search options on the BSL's Find a Fuel page.
The Woodsure Certification scheme comprehensively checks woodfuel producers to ensure that they produce and supply woodfuel that meets the EN and Önorm standards for woodfuel quality. Woodsure Certification covers woodchip, wood pellets, wood briquettes, hog fuel ("shred"), and firewood. For more information on this scheme, please click here.
is an internationally recognised quality certification scheme covering the entire wood pellet supply chain. ENplus
pellets meet, and in some cases exceed, the requirements of the ISO 17225-2 standard for pellets. There are three types of quality classes: ENplus
A2 and ENplus

All domestic RHI participants with boilers under 1,000 kW, who are sourcing woody biomass and wish to claim money under the RHI scheme must use fuel that is authorised on the BSL.
Non-domestic RHI participants with boilers under 1,000 kW, which are sourcing woody biomass can choose to use the BSL scheme to claim their RHI payments, instead of self-reporting to Ofgem.

Claiming RHI payments
For Domestic RHI participants, it is mandatory to use a BSL number to claim your RHI payments from Ofgem. Non-domestic RHI participants can either use a BSL number or self-report directly to Ofgem. For further information on the domestic RHI scheme, please click here, and for the non-domestic RHI scheme, please click here.
To make the process of claiming your RHI payments smoother, when purchasing fuel from an authorised BSL supplier, please ensure that the following information is included on your invoice:
- Name of your supplier
- BSL Authorisation number
- Quantity of fuel purchased (in tonnes/kg/m3/net heat/gross heat)
- Moisture content (% on a wet basis) of the final product (this could alternatively be included in your contract with the supplier)
- Fuel type
- Date sold
- Date delivered / collected
- Delivery address
- Your name
Please note that the BSL is a mark of fuel sustainability and legality only, it is not a mark of fuel quality.
For more information on fuel quality and dedicated fuel quality schemes, please go to the Fuel Quality tab on the left hand side.
