Chimney rebuild in the UK
Partial or full chimney rebuild — from the top courses down, or from the roofline up.
Typical UK cost range
£1,200–£5,000
National baseline. City-specific ranges are adjusted for local labour and access costs on the city pages below. See the full UK cost guide for the methodology and the factors that move a quote.
What the job involves
Chimney rebuilds range from replacing the top few courses of brickwork (where mortar has failed and the stack is leaning slightly) to a full stack rebuild from the roofline. The work involves dismantling the existing brickwork carefully, matching the replacement brick, and rebuilding in the original style.
Scaffolding is mandatory. On older Victorian stacks, matching the original brick and pointing style is the slowest part of the job — and the part that distinguishes a good rebuild from a patchy one.
What changes the price
- How much of the stack is being rebuilt — top courses vs full stack.
- Brick matching — reclaimed brick is more expensive than new.
- Scaffold hire (usually £600–£1,500 of a rebuild quote).
- Whether the pot, cowl, and flashing are being replaced at the same time.
Timeline: Top-course rebuild 1–3 days. Full stack rebuild 4–8 days plus scaffold time.

Do I need planning permission for a chimney rebuild?
Like-for-like rebuilds are usually permitted development and don’t need planning permission, except on listed buildings. Changing the stack height, adding a liner, or changing the flue arrangement may need Building Regulations approval.
Is a leaning chimney dangerous?
Yes. A visibly leaning stack has lost mortar integrity and is at risk of partial or full collapse. Get it inspected within days, not weeks. A structural engineer’s opinion is worth the £300 for peace of mind.
