Permitted Development Rules for a Biomass Boiler
Generally permitted under Part 14 of the GPDO. The boiler is installed internally and does not need planning permission. The flue is permitted under the same rules as chimney/flue installation (Part 1, Class G): it must not exceed the highest part of the roof by more than 1m.
Conditions
- 1The flue must not exceed the highest part of the roof by more than 1m
- 2Only one flue per dwelling under PD
- 3Must comply with smoke control area requirements (DEFRA-approved appliance)
- 4The flue must not be on the principal elevation fronting a highway in designated areas
- 5Fuel storage (pellet/chip hopper) is an internal or outbuilding consideration
Size and Dimension Limits
- Flue: must not exceed highest part of roof by more than 1m
- One flue per dwelling under PD
When Permitted Development Does Not Apply
- Listed buildings require listed building consent for flue installation
- Smoke control areas require a DEFRA-approved appliance
- External fuel storage follows outbuilding PD rules
- Emissions must comply with clean air legislation
What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply covering Part J (combustion appliances and fuel storage), Part L (energy efficiency), ventilation (adequate air supply), carbon monoxide detection, and flue design. A HETAS-registered installer can self-certify compliance.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Newcastle-under-Lyme building control or use an approved inspector.
