Wood fuel suppliers

Wood fuel can be produced from sustainable biomass resources and sold in a number of types and grades (chip, hog, pellets, firewood) which need to be matched to heat plant design for efficient operation.

  • The types of fuel are set out in the Technical Guide 1 (Solid Biofuel Classification Guidelines).

Commercial/industrial biomass fuel

Bioenergy Association has developed Technical Guide 6 (Contracting to Deliver Quality Wood Fuel to Customers) which outlines best practice for buying and selling wood fuel.  It includes a Model Contract for the Sale and Purchase of Wood Fuel and is linked to a Technical Guide 5 - (Standard Methods for Verifying the Quality of Solid Biofuels) outlining how to verify fuel quality when delivered.

Residential biomass fuel

Residential underfloor or space heating can be provided from combustion of solid biomass firewood or wood pellets. Accredited suppliers of firewood provide fit for purpose fuel according to customer requirements eg dry firewood for immediate use, or high moisture fuel which requires drying before use. Wood pellet fuel is produced to the required fuel specification set out in Technical Guide 1.. 

Accredited Wood Fuel Suppliers

Bioenergy Association operates a Wood Fuel Supplier Accreditation Scheme .  Accreditation ensures suppliers have the ability to supply quality fuel and that they have quality assurance processes and procedures in place for its reliable and consistent production, storage and delivery. Bioenergy Association-accredited wood fuel suppliers have demonstrated to an independent party that they reliably supply consistently-graded fuels.

Note that those who are Accredited Wood Fuel Suppliers are backed by the Association's Professional Standards and Complaints Scheme.
