Chimney Breast Removal Kew
Chimney breast removal with steel beam support in Kew, the beam sized by the engineer we appoint and the work signed off by building control.
- Rated 4.9 from 31 reviews on MyBuilder
- London guide: £2,200 to £3,250
- Free site survey, itemised quote
After the breast comes out, the flue is capped at the head and vented at the base so the void stays dry, and the wall is rebuilt flush and plastered. Done properly, nobody can tell there was ever a chimney there. Support above comes from steel that a structural engineer has sized for the load.
In Kew, removing a breast on one floor typically costs £2,200 to £3,250 on a steel beam, and £3,000 to £5,000 across two floors (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Kew.

How the job runs
- Free site survey at your Kew address: which floors the breast runs through, a shared stack, any live flue.
- The engineer we appoint designs the support, and the work is registered with Richmond Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- The floor above is propped and the breast comes down in courses from the top; what remains sits on the support the engineer specified.
- Building control inspects the support before it is covered. We make good, and the completion certificate follows.
Removing a chimney breast in Kew terraces
Most of Kew's bay-fronted terraces still have their original chimney breasts, and because the flues are built into the party wall, the stack is shared with the house next door. As the breast helps carry the masonry above, we never simply knock it out. A structural engineer first assesses exactly what the breast is supporting on each floor before any support is designed.
On the lower floors, the retained stack is carried on a steel beam bearing on padstones, or on gallows brackets only where the engineer and building control accept them. Where the stack runs the full height of the house and is genuinely redundant, it can be removed entirely and the roof made good, provided the house is not listed and the stack is not one a Kew conservation area expects to keep.
Housing in Kew
Kew counts roughly 4,470 homes for Council Tax; 62% are older than 1919, 6% interwar and 31% post-war, with 43% flats and 57% houses. The breasts of a terrace in Kew usually sit on the party wall back to back with next door's, so removing one needs a party wall notice, and 31% of homes here are terraced.
Kew chimney stacks under the Gloucester Road direction
Richmond lists an Article 4 Direction in conservation area CA2 covering Gloucester Road, Kew, and its guidance names removing chimneys among the changes that can need planning permission where a home is subject to one. On that road, taking a breast out inside an unlisted house remains building control work, but read the direction before the stack is scheduled. If it covers the stack, a full removal runs on two separate clocks: the inside work goes ahead with the stack carried on steel, while the stack waits for its decision.
Before the stack question is settled, decide what the remaining flues are for. In the 62% of Kew homes built before 1919, a breast can serve a fireplace on each floor, and taking out the ground floor breast removes the base of flues that may still serve rooms above. If an upstairs fireplace is to stay usable, its flue needs a route to the stack that survives the removal. The structural engineer we appoint and a flue specialist settle that together before the support is designed.
Party wall and building control in TW9
Because Kew's terraces are tightly packed and the chimney stack sits within the shared party wall, removing a breast or fixing gallows brackets affects that shared structure. That makes the work notifiable under the Party Wall Act, so you serve notice on your neighbour before anything begins, keeping the relationship on the street straightforward.
The structural support is notifiable under building regulations, and Richmond Council building control inspects and signs it off. We manage the whole job: the engineer's assessment, safe removal and propping, capping any redundant flue with ventilation to prevent damp, and replastering so there is no sign the breast was ever there.
Serving notice when next door is let
Party wall notices go to owners, and in a Kew terrace the owner is not always the person living there. Where the adjoining house is let, the notice has to be served on the freeholder, and also on any leaseholder with an unexpired term of more than a year. Both are adjoining owners under the Act, and missing one of them leaves the notice defective, which is the kind of thing that surfaces later at exactly the wrong moment.
So we establish who to serve before anything is drafted. A quick title check at the Land Registry usually settles it, and where a managing agent acts for an absent owner you serve them as well and keep the correspondence. Notices are delivered in a way that can be evidenced rather than posted through a door and forgotten. If nobody responds within fourteen days, the Act treats that as dissent and surveyors are appointed.
Birds, nests and the right season
A disused flue in a Kew terrace is a desirable address if you are a jackdaw. Nesting material builds up over years, sometimes filling several metres of the shaft, and owners tend to discover it only when the breast is opened and the lot comes down at once. It is worth knowing what is up there before work is planned. An active nest with eggs or young in it is protected while it is in use, so timing a job around the breeding season is occasionally the sensible answer rather than an inconvenience.
It is also a straightforward thing to check. A camera survey up the flue, or simply a look at the pot from the garden with binoculars during the spring, usually settles it. With Kew Gardens and the river so close, it is worth checking for in any TW9 flue. Old nesting material is bagged and removed with the rest of the debris, and where a stack is being retained we make sure the finished cap keeps birds out for good.

FAQ
Frequently Asked Questions about Chimney Breast Removal Kew
Is the price of chimney breast removal higher in Kew than elsewhere in South West London?
Work on chimney breast removal in Kew is priced from scope, so it costs no more than the same house in Brentford, typically £2,200 to £3,250 for one floor on a beam (indicative). Costs rise in period stock and with awkward access, both checked at TW9. What neither changes is the order of work: the stack above is supported before the breast below comes out. GS Renovation shows each as its own line.
Does the chimney pot need capping after breast removal in a Kew house?
Yes, if the stack and flue stay above. An open pot on a TW9 roof lets rain straight down a shaft that no longer has a fire to dry it, and a sealed pot traps damp instead. The answer is a capping cowl that keeps water out while letting air move, paired with a vent low down inside. Where the whole stack comes off, the pot goes with it.
Will removing my Kew ground floor chimney breast mean lifting the bedroom floor?
Often, yes. The beam carrying the retained breast upstairs usually sits within the ceiling zone, bearing into the walls either side, so some bedroom floorboards come up to fit it and pack it tight to the masonry above. Building control needs to see the bearings before the ceiling is closed. Clear the room above before work starts, since carpets and furniture have to be moved.
What if my Kew neighbour still uses their flue in our shared stack?
Then their flue must stay intact and working throughout. In a TW9 terrace both houses' flues often run through the same masonry, so the engineer's design keeps their flue in place while removing your breast. Party wall notice is served at least two months ahead. A smoke test on their flue before and after gives both sides proof it still draws properly.
Can I remove a chimney breast in my Kew flat when there is a flat above?
Only if the breast above gets its own designed support. Kew has 43% flats on the VOA count, and in a converted TW9 house the breasts stack up through every flat. Yours can go only once a beam carries the neighbour's section overhead. Expect to need the freeholder's licence, two months' party structure notice to the owner upstairs, and Richmond building control signing off the engineer's drawing.
Can the old chimney breast in my Kew closet wing kitchen be removed?
Usually, though closet wings need extra care. Many Victorian kitchens had a range with its own breast, and the closet wing wall it sits in is often thinner than the main house walls. The engineer checks whether that masonry can take a beam or brackets supporting what remains above. Where the stack is redundant, removing it entirely from the roof down is often simpler.
Does removing a chimney breast in Kew Green Conservation Area need planning permission?
The breast inside an unlisted house does not, since internal work is not what the designation controls. The stack can be different. Richmond's guidance names removing chimneys among the changes needing permission where a home is subject to an Article 4 Direction, and it lists one in CA2 for Gloucester Road. Kew Green Conservation Area number 2 was designated on 14.01.1969. Read the direction for your address before booking the scaffold for the roof.
Can a Kew chimney breast removal go ahead on a Building Notice?
A single breast on one floor, carried on a beam designed by the structural engineer we appoint, can fit what Richmond calls very simple work, which includes simple structural alterations. Breasts on two floors, or a stack left on the roof above a double removal, put real weight on the steel. For those a Full Plans application, with plans, specifications and calculations, lets Richmond check the support before the first course comes down.
Can the stack come down if our Kew house is a Building of Townscape Merit?
Being on Richmond's local list does not by itself bring in listed building consent, because a Building of Townscape Merit is one that is not statutorily listed. The planning question for the stack turns on whether an Article 4 Direction covering the house reaches chimneys. Where one does, removing the stack needs permission. Where none does, the stack is handled like the breast below it: building control for the support, and a party wall notice from you, as building owner, if it sits on the party wall.
