This section provides regular updates on changes to the BSL.


Following the recent communication regarding the concern about the usage of waste wood in biomass boilers and after listening to feedback from the industry, BSL will be releasing a new waste wood guidance document.

This guidance document has been created to provide clarification on:

  • What waste wood is
  • Waste wood classifications
  • Waste wood quality standards
  • Legislation around the legal usage of waste wood

The BSL advisory panel has discussed the issue and after careful consideration, they recommended that guidance is tightened to restrict waste wood of unknown provenance.

We aim to release this guidance document as soon as possible. The Department for Business, Energy & Industrial Strategy (BEIS) will make a final decision based on this recommendation and the actual release date will be announced soon.


A useful waste wood guidance document produced by the Environment Agency can be read here.


A BSL Advisory Panel has been set up to discuss and input into how the BSL is run and make recommendations to BEIS (formerly DECC). The first Panel meeting was held on 16 December 2016. 

A Decisions and Actions report on the meeting can be found here.


The final list of members of the BSL Advisory Panel has been finalised following the election, and the first meeting was held on 16 December 2016. The list of members can be found here.


From 1 January 2017, all BSL suppliers will have to pay fees to have authorised fuels on the Biomass Suppliers List. Further information on the charges, including how much and when the fees need to be paid is available to read here. You can also read the BSL Charges - Questions and answers document, which answers frequently asked questions about the fees and how much, and when, to pay. 


The BSL Advisory Panel election has opened. An email was issued to Master Admin Users for all suppliers on the BSL today with a voting form and details on how to vote attached. Voting closes on 22 November 2016.
