Do I Need Planning Permission to Remove a Chimney?
IT DEPENDS
Removing an internal chimney breast or stack is usually permitted development and does not need planning permission. However, in conservation areas the removal of a chimney visible from a highway may need permission, and listed buildings always require listed building consent. Building regulations notification is required for structural chimney removal.
Keep reading for the full rules.
Removing a chimney — whether an internal breast or an external stack — is a common home improvement that is usually permitted development. The key questions are: is the chimney visible from a highway (relevant in conservation areas), is the property listed, and is the chimney party (shared with a neighbour)? Building regulations must be followed to ensure structural safety.
Permitted Development Rules by Region
Permitted Development Rules — England
- ✓Removing an internal chimney breast is not a planning matter — it is an internal alteration and is permitted development (subject to building regulations for structural work).
- ✓Removing a chimney stack (the external part above the roof) is generally permitted development under Class C of the GPDO, as it falls within the householder PD rights for roof alterations.
- ✓In a conservation area, removing a chimney that is on or visible from the principal elevation (facing a highway) may require planning permission — permitted development rights are more restricted.
- ✓Article 4 Directions can remove PD rights for chimney alterations in sensitive areas — check with your LPA.
- ✓Listed buildings: any removal of a chimney — internal or external — requires listed building consent. This applies to both Grade I and Grade II listed buildings.
Size & Position Limits (England)
| Requirement | Limit / Rule |
|---|---|
| Internal chimney breast removal | No planning permission needed — building regs required |
| External chimney stack removal | Usually permitted development |
| Conservation areas (principal elevation) | May require planning permission |
| Listed buildings | Listed building consent always required |
| Party chimneys | Party Wall Act applies — serve notice on neighbours |
When Do You Need Planning Permission?
Even if your project is usually permitted development, planning permission is required in these circumstances:
- ✗Your property is in a conservation area and the chimney is on or visible from the principal elevation (front).
- ✗Your property is a listed building — listed building consent is required for any structural alteration.
- ✗Your council has an Article 4 Direction that specifically includes chimney alterations.
- ✗The chimney is shared with a neighbour (party chimney) — party wall notice required under the Party Wall etc. Act 1996.
What Happens If You Build Without Permission?
Removing a chimney without the required listed building consent is a criminal offence. In conservation areas, unauthorised removal of a chimney on the principal elevation can attract enforcement action. Structural chimney removal without building regulations notification can create dangerous voids and structural instability.
Enforcement notices: Your council can issue an enforcement notice requiring you to stop the work, remove it, or restore the land to its original condition. You have a right of appeal against an enforcement notice.
Retrospective applications: If you have already carried out work that required planning permission, you can submit a retrospective planning application. If approved, this regularises the work. If refused, you may be required to remove it.
Time limits: For dwelling houses, the council generally has 4 years to take enforcement action for most types of work. For breaches of planning conditions, the time limit is 10 years. There is no time limit for listed building enforcement.
