Renewables: Biomass

Heating your property using biomass such as wood can be a good, cost effective and environmentally friendly way to heat your home.

Biomass heating can come in various forms, from small woodburning stoves, to automated wood pellet boilers, and so can be suitable for a range of budgets. Biomass heating can burn logs or pellets to heat a single room or they can be used to heat hot water, as well as work with a property's existing radiators.

Biomass pellet boilers can cost between £8,000 and £15,000 and the savings on bills depend on the current heating system in place.

Carbon savings

Using wood as a fuel source is classed as renewable and low carbon because it only releases the same amount of CO2 that it absorbed by the tree/crop whilst growing. However, it is important to source wood locally as possible to reduce transportation emissions and ensure that the wood is harvested sustainably.

Is your home suitable?

  • Your property is not listed building or in a conservation area. To check contact your local council's planning department 
  • Your property does not sit within a smoke control zones
  • Check that you have a large enough space to store fuel, which is also easy for deliveries and feeding the boiler
  • Check you have a local fuel supplier, to keep costs down
  • Make sure the biomass heating system is sized correctly to the room that it will be placed
  • Check that you have enough room for a flue, which meets the regulations for a wood-burning appliance. 

Financial incentives

Biomass boilers can be eligible for the government’s Renewable Heat Incentive (RHI) scheme. This will pay property owners annually over a period of 7 years for the heat that their heat pump generates. Visit our Grants page for more information on the Renewable Heat Incentive.
