Planning permission is not normally needed when installing a biomass system in a house if the work is all internal. If the installation requires a flue outside, however, it will normally be permitted development if the conditions outlined below are met.
- Flues on the rear or side elevation of the building are allowed to a maximum of one metre above the highest part of the roof.
- If the building is listed or in a designated area even if you enjoy permitted development rights it is advisable to check with your local planning authority before a flue is fitted. Consent is also likely to be needed for internal alterations.
- In a conservation area or in a World Heritage site the flue should not be fitted on the principal or side elevation if it would be visible from a highway.
If the project also requires an outside building to store fuel or related equipment the same rules apply to that building as for other extensions and garden outbuildings.
If you wish to install a biomass appliance, building regulations apply. You should take into account factors such as ventilation, noise and general safety. Installation should be carried out by a suitably qualified installer.
Building regulations also apply to other aspects of the work such as electrical installation and plumbing work. It is advisable to contact an installer who can provide the necessary advice, preferably one who belongs to either theMicrogeneration Certification Scheme or the relevant Competent Person Schemes.
