Restrictions for Biomass-Fuelled Appliances

Restrictions for biomass fuelled appliances

If you want to install a biomass fuelled appliance in your property, you do not generally need to apply for planning permission to do so. Installing biomass fuelled appliances falls under permitted development in most cases, however, building regulations do apply.

Planning permission

You do not need to apply for planning permission to install a biomass fuelled appliance within your home. However, this applies only if all work undertaken is internal. If your project requires an external flue, you may require planning permission, although this is also classed as permitted development in many cases.

The installation of a biomass appliance does not fall under permitted development where:

  1. Flues located on the rear or side elevation of a property exceed one metre higher than the highest point on the roof.
  2. A building is listed or within a conservation area with planning restrictions.


Building regulations

If you are to install a biomass appliance, building regulations apply. These building regulations cover: ventilation, noise and safety.

If the installation of a new biomass appliance requires new electrical or plumbing work, we recommend that you hire a professional installer to do the work for you. If you do not, you will have to notify Building Control of your work, who will inspect your project upon completion. You should hire an installer who belongs to the Competent Persons Scheme or the Microgeneration Certificate Scheme.

Outside fuel storage

The storage of fuels for a biomass appliance must be safe and fit for purpose. Any new outbuildings that are designed to store fuel or related equipment will need to follow the planning limitations for outbuildings and other home extensions.
