How Much Does Chimney Removal Cost in the UK?
Chimney removal cost depends on how much you remove — just the stack above the roof, or the full breast through the house — and the structural support and making good needed.
A partial above-roof removal at the low end; a full chimney breast removal at the top.

Cost by scope
What affects the price
- •How much is removed — stack only, one floor, or the full breast through every floor.
- •Structural support — remaining chimney needs supporting with gallows brackets or a steel beam (RSJ), which a structural engineer must specify.
- •Making good — new roof tiles, plastering, flooring and skirting where the breast was.
- •Scaffolding and access for the roof work.
- •Building Regulations approval and a structural engineer’s calculations.
Regional price variation
Labour is the biggest regional swing. London and the South East typically run 20–30% above the national average, while the North of England, Scotland and Wales tend to sit 5–15% below it. Material prices are fairly consistent nationwide — it is day rates that move the total. The ranges on this page assume South of England pricing unless stated.

Frequently asked questions
How much does it cost to remove a chimney in the UK?
Chimney removal costs around £600–£1,500 to take down just the stack above the roof, £1,500–£4,000 for a full chimney breast removal through the house, and up to £5,000 for a complete internal and external removal including making good.
Do I need Building Regulations to remove a chimney?
Yes. Removing a chimney breast affects the structure, so it needs Building Regulations approval and usually a structural engineer to specify how the remaining chimney is supported (gallows brackets or a steel beam).
Can I remove just part of the chimney?
Yes — removing just the stack above the roofline (£600–£1,500) is common when a chimney is no longer used, and avoids the disruption of taking out the breast inside the house. The roof is then made good where the stack was.
