Rules for biomass fuel use
In October 2015 rules to support sustainable fuels for the Domestic RHI came into effect for everyone with a biomass heating system. They apply whether you're in the process of joining the scheme or you’re already a member.
It's important that you're complying with these new rules as they affect your eligibility to receive payments.
What are the requirements?
All applicants with biomass systems must use an approved sustainable fuel from a supplier listed on the Biomass Suppliers List (BSL).
If you use fuel from your own land/woodland, you may be considered a ‘self-supplier’. You must register the fuel you use on the BSL and list yourself as a ‘self-supplier’.
If you self-supply but also buy in raw materials which you process yourself, you must register on the BSL as a ‘producer-trader’. You do not need to register separately as a self-supplier.
For more on how to register and self-supply classifications, view the BSL guidance.
How to prove you’re using an approved fuel
A statement about fuel will be included in your 'annual declaration' which is how we check that you’re still complying with your ongoing obligations. We email this to you each year to confirm you're still following the scheme rules. In it you'll have to enter the BSL authorisation number for each fuel you use, which you should be able to find on your fuel receipts. If you're a self-supplier or producer-trader, you'll need to enter the BSL authorisation number you received from Gemserv (the BSL administrator), along with the numbers of any other fuel you use. BSL authorisation numbers take the format 'BSL-1234567-1234'.
Keep a record of your fuel purchases which show your fuel authorisation numbers. You'll need them not only for your annual declaration, but also if we select your biomass heating system as part of our ongoing audit checks.

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