Fuel costs per kWh

Typical prices for bulk purchase of fuels at domestic scale, January 2010

N.B. These prices are intended for guidance only and represent the typical cost per unit of fuel energy for comparison. This is not the same as cost per unit of delivered heat which will depend on the efficiency of the boiler or stove, and may also include other charges such as service and maintenance for heat supply contracts.

All prices are prone to significant variation with geographical region, order quantities, overall contract size and duration, time of year, delivery distance and time, etc. Woodfuels in particular are available at prices both significantly above and below those quoted, and bulk prices will be subject to a minimum delivery size of perhaps 3-5 tonnes. Wood pellets bought in bags may be significantly more expensive than those bought in bulk.

The market for woodfuels is currently relatively immature which, combined with its unsuitability for long distance transport, supports considerable variation in prices from place to place. Figures have been chosen to represent the mean price achievable across the UK for a single bulk order of 5 tonnes of wood pellets or 10 tonnes of woodfuel quality chips. In the case of the latter however, the prices we see around the country and from different suppliers can vary by a factor of two or more, with £60 - £90 a typical range, but figures both above and below this are not uncommon. For some producers, prices may be subsidized by other activities,

Fuel Price per unit kWh per unit pence per kWh
Wood chips (30% MC) £80 per tonne 3,500 kWh/t 2.3p/kWh
Wood pellets £185 per tonne 4,800 kWh/t 3.9p/kWh
