Permitted Development Rules for a Flue or Extraction System
Generally permitted under Part 1, Class G of the GPDO. One flue, chimney, or soil and vent pipe is permitted on a dwelling provided it does not exceed the highest part of the roof by more than 1 metre. The flue must not be on the principal elevation in designated areas.
Conditions
- 1Must not exceed the highest part of the roof by more than 1m
- 2Only one flue per dwelling under PD
- 3Must not be on the principal elevation or side elevation fronting a highway in designated areas
- 4Kitchen extraction: external vent or ducting follows the same rules
- 5Must comply with clean air legislation if for a combustion appliance
Size and Dimension Limits
- Must not exceed the highest part of the roof by more than 1m
- One flue only under PD
When Permitted Development Does Not Apply
- Listed buildings require listed building consent
- In conservation areas, position and appearance restrictions apply
- Odour and noise from extraction systems can be a statutory nuisance
- Additional flues beyond the first require planning permission
What About Building Regulations?
Building regulations approval is likely required
Building Regulations apply if the flue or extraction system serves a combustion appliance (Part J). Kitchen and bathroom extraction must comply with Part F (ventilation). Gas flues must be installed by a Gas Safe registered engineer. A HETAS-registered installer can self-certify solid fuel installations.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Fareham building control or use an approved inspector.
How to Apply in Fareham
If you need planning permission for your flue or extraction system, you can apply through Fareham's planning department or via the national Planning Portal.
If your project is permitted development and you want written confirmation, you can apply for a Lawful Development Certificate (LDC) from Fareham. This provides proof that your project does not need planning permission, which can be helpful when selling your property.
What Happens If I Build Without Permission?
Low risk for standard domestic flues within PD limits. Extraction systems that cause odour or noise nuisance to neighbours are more likely to be addressed under environmental health legislation than planning enforcement.
