Planning chimney breast removal in Kent
Chimney breast removal is taking out the projecting brickwork that houses the flues from fireplaces, usually to gain floor space or straighten a wall. If any of the breast or stack above stays in place, it must be carried on steel or another support the engineer designs and building control accepts, so it is never left unsupported.
If you are planning chimney breast removal in Kent, the order of work matters as much as the steel: survey, calculations, approval, propping, installation, inspection and making good. Coverage takes in Chatham, Margate and St Peters and everywhere in between. We run that sequence for you as one job with one point of contact.
What to expect
- Gallows brackets are steel angle brackets fixed into the wall to hold a breast above. They are often not accepted where the remaining masonry is heavy or sits against the neighbour's breast, so the engineer and building control decide which support method is suitable.
- A chimney closed off at both ends can trap moisture and cause damp patches on the walls. Where part of a flue remains, a vent at room level and a ventilated cap on the pot keep air moving through it.
- A chimney breast removed without proper support or approval is a frequent issue raised in surveys when a house is sold. Keeping the calculations, completion certificate and any party wall documents shows a buyer that what remains was properly supported.
- Removing only the ground-floor breast leaves the upper breast and stack in place, so they must be supported. Taking the breast out on every floor and removing the stack above the roof avoids that load entirely, but involves roofing work and more disruption.
- Removing a ground-floor breast with steel support typically takes two to four working days. Full-height removal including the stack and roof repair takes longer and depends on scaffolding, roofing access and the weather.
How the job runs in Kent
Free visit
A short visit to Kent to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building rules for Kent
Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Chimney breast removal in Kent: your questions
How much does chimney breast removal cost in Kent?
As a guide, budget £1,700–£3,350 including VAT for chimney breast removal (ground floor) in Kent, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
Do you cover Kent for chimney breast removal?
Yes. We carry out chimney breast removal in Kent. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
How long does chimney breast removal take?
A ground-floor breast with a steel beam supporting the masonry above usually takes two to four working days, including propping, fitting the steel, removing the brickwork and basic making good. Full removal from ground floor to roof takes longer because of scaffolding, roofing work and weather, and plaster needs time to dry afterwards.
Do I need building regulations to remove a chimney breast?
Yes. Removing all or part of a chimney breast is structural work. In England it needs building regulations approval through a full plans application or building notice, and in Wales an application under the Welsh regulations; in Scotland a building warrant is needed before starting; in Northern Ireland an application goes to council building control. We prepare and submit this with the engineer's calculations.
Will removing a chimney breast cause damp?
It can if the remaining flue is sealed with no airflow, because moisture and condensation get trapped inside. Fitting a vent in the remaining breast or wall and a ventilated cap on the chimney pot keeps air moving. If the stack is removed and the roof made good, the risk from the flue goes away.
Do I need my neighbour's permission to remove a chimney breast?
Not permission as such, but in England and Wales you must serve notice under the Party Wall etc. Act 1996 if the breast is attached to a party wall, and your neighbour can consent or dissent. You cannot remove their half of a shared stack. Scotland and Northern Ireland have no equivalent Act, so the title deeds and general law apply.
