Important: Additional Restrictions May Apply in Herefordshire
Herefordshire has 64 conservation areas. These include Almeley, Aylestone Hill, Aylton, Bircher, Bodenham, Bodenham Road. If your property is in a conservation area, some or all permitted development rights may be restricted. For example, you may need planning permission for changes that would normally be permitted, including alterations to the roof, cladding, or extensions visible from a public highway.

If your property is covered by an Article 4 direction, you may need planning permission for work that would normally be permitted. Contact Herefordshire planning department to check whether an Article 4 direction applies to your property.

Permitted Development Rules for a New Chimney or Flue
Generally permitted under Part 1, Class G of the GPDO. One flue is permitted on a dwelling house 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 or a side elevation fronting a highway.
Conditions
- 1Must not exceed the highest part of the roof by more than 1 metre
- 2Only one flue per dwelling under PD
- 3Must not be installed on the principal elevation or a side elevation visible from a highway (in designated areas)
- 4Must comply with clean air legislation if in a smoke control area
Size and Dimension Limits
- Must not exceed the highest part of the roof by more than 1m
- One flue only under PD rights
When Permitted Development Does Not Apply
- Smoke control areas restrict the type of fuel and appliance that can be used
- Listed buildings require listed building consent
- In conservation areas, additional restrictions may apply to the flue's position and appearance
- Additional flues beyond the first require planning permission
What About Building Regulations?
Building regulations approval is likely required
Building Regulations approval is required covering flue design and installation (Part J, combustion appliances and fuel storage), fire safety (distance from combustible materials), ventilation (adequate air supply to the appliance), and carbon monoxide detection. A HETAS-registered installer can self-certify the work.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Herefordshire building control or use an approved inspector.
How to Apply in Herefordshire
If you need planning permission for your new chimney or flue, you can apply through Herefordshire'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 Herefordshire. 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 a single flue within PD limits. Flues that are excessively tall or in prominent positions may attract enforcement. Installing a wood burner in a smoke control area without an approved appliance is an offence under the Clean Air Act.
