If you are budgeting for a chimney take-down on a property in Dilham, here is a clear and honest look at what the work typically costs and what drives the price up or down.

Before looking at figures, it helps to be clear on what a chimney take-down actually involves, because it is not just the demolition. A complete job covers: erecting scaffold for safe access, taking down the stack course by course to below roof level, inspecting and if necessary repairing the timber framing around the chimney opening, capping the remaining masonry, laying new felt and battens, and tiling or slating over the gap with material that matches the existing roof as closely as possible. Rubble disposal is part of it too.
If any of those elements are missing from a quote, you are not comparing like for like. A quote that does not mention scaffold, or lumps disposal in as an extra, will look cheaper than it is.
A standard chimney take-down on a typical domestic property in Norfolk - a single stack of moderate height above the roofline, with reasonable access and a straightforward roof make-good - costs broadly between £1,000 and £2,000. This is a realistic current UK range, not a best-case figure.
Where the stack is larger, taller, more awkwardly positioned, or where the make-good is more involved, the cost can rise to £2,500 or beyond. Very large stacks serving multiple flues can cost more still. Each job needs to be assessed on its own terms.
For context: the scaffold alone can account for £300 to £600 of the total on a typical job, depending on how long it needs to be in place and what access equipment is required. This is why a doorstep quote without a proper look at the stack and roof is not worth much.
Several factors make a chimney take-down more expensive than the baseline figure. Understanding them helps you anticipate where your own job might sit.
A stack that projects a long way above the roofline involves more brickwork to remove and more time on the scaffold. Taller stacks also require higher and more substantial scaffold, which costs more to erect and tie safely. A stack of six or seven courses above the roof is a much smaller job than one of fifteen or twenty courses.
A double or triple flue stack - the kind that serves several fireplaces on different floors of the house - is significantly larger in cross-section and mass than a single flue stack. More brickwork means more time, more rubble to dispose of, and a larger make-good area in the roof.
A chimney sitting on a straightforward main slope is the easiest to deal with. One positioned at the ridge, in a valley, or on a rear extension roof that is difficult to reach adds complexity and time. On some properties, the scaffold has to be configured to reach an awkward part of the roof, which increases the cost of erecting it.
If the chimney has been leaking for some time before the take-down is carried out - and a good proportion of redundant stacks have been - it is likely that the timber framing around the opening has been affected by damp. Soft or rotten timber needs to be cut back and replaced before the roof covering goes on. This is non-negotiable if the finished job is to last, but it does add cost and is not always foreseeable until the stack is down and the framing is exposed.
Closing the hole in the roof requires tiles or slates that match the existing covering as closely as possible. On a roof with common modern concrete tiles, matching is straightforward and inexpensive. On a roof with handmade clay plain tiles, old Norfolk peg tiles, or natural slates, sourcing a decent match takes more effort and reclaimed material costs more. A difficult-to-match roof covering can add £100 to £400 or more to the material cost depending on what is needed.
Where the stack sits at or near the ridge, existing ridge tiles need to be lifted, extended and re-bedded or replaced to close the gap cleanly. In a valley, valley lead or a valley liner needs to be extended and carefully dressed. Both add time and material cost over a straightforward slope position.
Scaffold hired for a day is cheaper than scaffold left on hire for a week. If poor weather delays the work, or if the job turns out to be more involved than expected once the scaffold is up, the hire cost increases. Most contractors factor a contingency into scaffold costs, but it is worth asking how they handle delays when getting your quote.
Combining the chimney take-down with other roofing work on the same scaffold can reduce the overall cost, because the scaffold is already in place and the mobilisation costs are shared. If you know the roof needs other attention - a ridge re-bed, some tile replacements, a re-dress of other flashings - it is worth discussing whether it makes sense to do it at the same time.
Acting before the stack has deteriorated too far also keeps costs down. A chimney that has been leaking for years is more likely to have caused timber damage than one where the take-down is carried out as a planned decision. The sooner a redundant stack is dealt with, the less likely it is that collateral damage has accumulated.
A useful quote for a chimney take-down should specify: what is included in the scaffold, how the make-good will be carried out (felt, battens, tiles or slates), what happens if the timber framing is found to be damaged, and whether rubble disposal is included. If it does not cover these points, ask. Any roofer confident in their work should be able to answer clearly.
Be cautious of a very low quote that does not mention scaffold or disposal separately. These are real costs that have to be met by someone - if they are not on the quote, they may appear as extras later, or they may indicate that the job will not be done properly.
