This is general guidance based on standard permitted development rights in England. Rules differ for listed buildings, conservation areas, and properties with Article 4 directions. Always confirm with your local planning authority before starting work.
Do I Need Planning Permission for a Chimney Removal?
Removing a chimney breast internally, reducing the chimney stack externally, or removing the chimney entirely. Internal removal is generally PD, but external changes to the roofline may need planning permission.
The General Position
This project is usually allowed under permitted development rights without needing to apply for planning permission, provided certain conditions and limits are met.
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 and Requirements
- 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 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. You may need both, one, or neither depending on your project. Building regulations cover the safety and quality of building work, including structural integrity, fire safety, insulation, ventilation, and drainage.
How to Apply for Planning Permission
Check if you need permission
Review the permitted development rules above. If in doubt, contact your council or apply for a Lawful Development Certificate.
Prepare your application
You will need scaled drawings, a site plan, and a completed application form. An architect or planning consultant can help with this.

Applications can be submitted online via the Planning Portal or directly to your council. Select your council below for a direct link.
Wait for a decision
8 weeks for householder planning applications if PP is needed..
Application cost: £258.
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.
