Biomass Wood Chip Fuel & Kiln Dried Premium Firewood

About Us

Chip Chip Ltd was set up specifically to provide consistent, virgin high quality, dry and contaminant free wood fuel for biomass boilers in the UK

Chip Chip is a consistent quality, high calorific wood chip fuel specifically produced to get the highest possible performance from biomass boilers.

From our own depots across the UK, the company sells only sustainable, traceable, high quality dried wood fuel that conforms to the stringent rules set out by the Biomass Suppliers List and The Green Dragon Environmental Management Standard – Level 4.

Chip Chip wood fuel is tested monthly at a UKAS Accreditation Centre for particulate size, fines content and moisture content. Additionally, daily checks are undertaken in-house via the company’s own Quality Assurance Scheme.

By chipping its own wood, Chip Chip ensures product consistency. Experience has proven that particulate size cannot be guaranteed by a third party chipper. The wood is chipped when wet to BS EN 14961, then dried to the moisture content as required.

High performance biomass boilers are only as good as the fuel they burn. Anything other than virgin wood with no more than 25% moisture content will have a negative impact on the kWh output and RHI payments. Chip Chip produces 25% moisture content (+/- 2%) to ensure the fuel burns cleanly and efficiently and results in higher kWh output and higher calorific value per tonne. Wood chip with little or no moisture content burn too rapidly. Wood chip with more than the recommended moisture content reduces the power output and causes excessive tarring, ash production and emissions.

Chip Chip currently have 10 locations around the UK, and growing.  So whatever the location or volume demand they are able to meet client needs quickly and efficiently.


Chip Chip force dried wood chip is a great value sustainable form of heating fuel for buildings of all sizes. There is a common misconception that cutting down a tree is not good for the environment. Here at Chip Chip we have an ethical planting policy in place. We ensure that all the wood purchased from our supply chain comes from properly managed woodlands that comply with the Forestry Commission Standard for managing woodlands. That means for every tree that gets cut down for our wood chip production many more get replanted. These new growing trees absorb more carbon than mature trees. Only 2% of these managed forests are harvested in any one year, leaving 98% to absorb the carbon released.
