For a standard single chimney stack on a domestic property, a chimney take-down typically costs in the range of £800 to £1,500 fully completed. That figure covers taking the stack down to below roof level, fitting a lead slate over the opening, re-tiling the disturbed courses with matched tiles, and removing all the demolition waste from site.
A double stack - two flues within a single chimney structure - usually sits in the range of £1,200 to £2,000, depending on the height of the stack and the complexity of the tile matching involved.
These are realistic current market figures for a competent job done properly. A quote that is significantly lower may not include all of these elements - it is worth checking exactly what is and is not included before comparing figures.
The height of the chimney stack above roof level, and how accessible it is, has the largest effect on price of any single variable.
Scaffold is usually needed for chimney work, both for safety and to allow bricks to be lowered properly rather than dropped. The cost of erecting, hiring and striking scaffold varies with the height and position of the stack. A chimney on a standard two-storey house with straightforward roof access costs less to scaffold than one on a three-storey end-of-terrace, or one positioned over a bay window or extension where the scaffold platform needs to be larger or more complex.
For very accessible stacks on bungalows or single-storey extensions, a scaffold tower or purpose-built platform may be sufficient, which reduces the access cost noticeably. This is worth raising when you get quotes - it is not always the case that full scaffold is needed.
A taller stack means more brickwork to dismantle and lower, and more rubble to clear and remove. A chimney that stands a metre above the ridge takes longer to take down than one that only just clears it. Multiple pots - some stacks have three or four on a single structure - add handling time because each pot needs to be lowered safely.
Unusually large or decorative terracotta pots are heavier than standard ones and take more care to move. If the pots are in good condition and the homeowner wants to keep them, this needs to be factored into the handling rather than simply setting them aside. If they are going for disposal, they go with the rest of the rubble.
Once the stack is down, the disturbed tile courses around the old chimney base need to be relaid. If the tiles in that area are brittle, broken or no longer available as a matched product, the tile reinstatement becomes more complicated and more expensive.
Old clay plain tiles, handmade tiles or very early concrete tiles can be difficult to match from current stock. Sourcing reclaimed tiles takes time and the cost of the tiles themselves varies considerably - reclaimed clay plain tiles can cost two to three times as much per tile as equivalent new concrete tiles. On a roof where matching matters, this is a genuine cost factor.
If the roofing felt underneath the disturbed area is in poor condition and needs replacing in that section, that adds modest material and labour cost but is worth doing while the tiles are already lifted.
If water has been getting in around the chimney stack for some time - whether through failed flashing, cracked flaunching or open mortar joints - there is a chance that the rafters or roof timbers immediately around the old flue penetration have been affected by damp. Early-stage softening of timber, or in worse cases active rot, needs to be dealt with before the roof is closed up.
Minor timber repairs - sistering a damaged rafter section or replacing a short length of batten - add a relatively small amount to the job cost. More extensive repairs to the roof structure are less common but do occur on properties where a leak has been running undetected for several years. A roofer who spots a problem at the assessment stage and tells you about it before work starts is doing their job properly. One who closes the roof without mentioning it is not.
Lead is a traded commodity and its price moves with the metal markets. The cost of lead for a lead slate is not large in the context of the overall job, but it is worth knowing that quotes obtained several months apart may differ partly for this reason rather than purely contractor variation. Quotes are generally valid for a defined period - usually 30 days - and it is reasonable to ask how long a quote remains fixed if you are not ready to proceed immediately.
The two elements where cutting costs tends to create future problems are the access set-up and the lead slate.
Working without proper scaffold on a tall stack creates safety risks and makes it harder to lower bricks carefully, which increases the risk of tile damage. And a chimney take-down finished with mortar-only tile patching rather than a proper lead slate will very likely admit water within a few years, because mortar joints crack as the roof moves. That leak will need finding and fixing, and accessing it properly often costs more than the original lead slate would have.
A useful quote for a chimney take-down should specify: the stack height, the method of access, what the opening will be finished with (lead slate or otherwise), whether tile matching has been factored in, and whether waste removal is included. If any of these are absent from a quote, ask specifically.
