A reporting route for demonstrating compliance with the sustainability criteria used by participants not able to or who choose not to source from the Biomass Suppliers List (BSL) or register as a self-supplier (or producer/trader) on the BSL. This applies to all biogas installations and biomethane producers as well as all installations over 1MW. Self-reporters will need to keep evidence to demonstrate the fuels they used in each quarter meet the land and greenhouse gas emission criteria, and must report this evidence quarterly.

Someone who supplies fuel for their installation from either their own woodland, or somewhere they have the legal right to source from, and which is within 50 miles of the boiler. They must register on the BSL as a self-supplier and provide the necessary information to the BSL. They cannot sell fuel to a third party and have the option to purchase fuel from a BSL-authorised supplier. They must also meet the emissions criteria.

An installation which uses standard metering requires a single ‘quantity’ to be measured for RHI payment purposes. This is an only applicable to applicants applying for accreditation on or after the 24th of September 13.
