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.
