Welcome to the Biomass Suppliers List

The Biomass Suppliers List (BSL) is a list of woodfuel that has proven it meets the eligibility requirements for the Renewable Heat Incentive (RHI) scheme. It allows RHI participants to easily demonstrate to Ofgem that the fuel they are using in their biomass boilers meets the RHI sustainability criteria required to claim their RHI payments.

Fuel Quality Requirements

BSL authorisation does not guarantee the quality of the fuel as it is not a quality scheme. Early in 2021 legislation was introduced that made a number of changes to the Renewable Heat Incentive. The changes to the RHI which impact upon accredited Biomass Suppliers List (BSL) fuel suppliers came into effect on the 1st April 2022. The legislation places requirements on both self-suppliers AND commercial suppliers (Producers, Traders and Producer-Traders). Visit the ‘Fuel Quality’ section in the ‘About‘ tab to find out more about the legislative requirements and take action to ensure your fuels comply.

Please be aware that the Government has introduced a suspension of fuel quality for pellets only and came into force 23rd November 2022 for a period of up to 1 year.   This means that the fuel quality requirements for wood pellets for use in biomass boilers and plant where the owner receives Renewable Heat Incentive payments via OFGEM are not required while this suspension is in effect. 

Fuel quality remains an important consideration for purchasers of pellet fuels for biomass boilers and plant, as it can affect the operation and efficiency of your boiler and incorrect quality could lead to RHI payments being suspended, store clear outs, higher emissions or boiler breakdowns. 

Things to check: We recommend that you check the following before you order any pellets and ensure you talk to your supplier to confirm if the pellets you are ordering are right for your boiler: 

  • Your boiler warrantee which may be invalidated if the correct fuel specification is not used 
  • Your maintenance contract, if any 
  • Your boiler emissions certificate – which will mention the fuel specification for the boiler
