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. Please note that BSL authorisation does not guarantee the quality of the fuel.

Introduction of fees

Fees are being introduced to the BSL from 1 January 2017.  This will affect all new applications submitted after 1 January 2017 and all existing authorised suppliers on the BSL. You can find the final charges in the final BSL charges and consultation feedback report and further information in the BSL Charges - Questions and Answers document.

For more information on the RHI sustainability criteria and dedicated fuel quality schemes, please click the About tab.

When you are ready to apply to the scheme, please register for a supplier account by clicking the Supplier registration tab. Please note that from January 2017, all new applications will be subject to an application fee. More information on the exact charges will be announced in the coming weeks.

RHI participants

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, who are sourcing woody biomass can choose to use the BSL scheme to claim their RHI payments, instead of self-reporting to Ofgem.

To find a local supplier of BSL authorised fuels, please type your postcode into the Find a fuel box above.
