Permitted Development Rules for a Chimney Removal
Generally permitted. Internal chimney breast removal is an internal alteration that does not need planning permission. Removing the external chimney stack above the roofline may be PD provided it does not significantly change the roof's appearance. In conservation areas or for listed buildings, additional consents apply.
Conditions
- 1Internal removal of a chimney breast does not require planning permission
- 2Reducing or removing the external stack may be PD if the roof is made good
- 3Must ensure structural integrity of the remaining building (party wall, load-bearing considerations)
- 4In terraced or semi-detached houses, chimney stacks shared with neighbours may have party wall implications
Size and Dimension Limits
- No specific dimensions; the work is removal rather than addition
When Permitted Development Does Not Apply
- Listed building consent is required for chimney removal on listed buildings
- In conservation areas, removal of a chimney that contributes to the character of the area may need PP
- Party Wall Act 1996 applies if the chimney is shared with an adjoining property
- Must retain any fire-stopping and structural support needed by the remaining building
What About Building Regulations?
Building regulations approval is likely required
Building Regulations approval is required covering structural support for remaining floors and walls (gallows brackets or steel supports), fire stopping where the chimney passes through floors and the roof, and ensuring the remaining structure meets fire safety standards.
Building regulations are separate from planning permission. Even if your project is permitted development, you may still need building regulations approval. Contact Spelthorne building control or use an approved inspector.
How to Apply in Spelthorne
If you need planning permission for your chimney removal, you can apply through Spelthorne'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 Spelthorne. 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 enforcement risk for internal removal with proper structural support. Removing an external chimney in a conservation area without consent may attract enforcement. Structural failure from inadequate support is a building safety issue that can lead to prosecution.
