Chimney breasts take up a surprising amount of room, especially in the kitchens and bedrooms of older terraces and semis. Removing one is common, but it is structural work: the breast usually continues upstairs and up through the roof, and in terraces the stack is often shared with the house next door.
What to expect
- Older fireplaces sometimes contain asbestos in flue linings, fire surrounds, hearth boards or heat-resistant panels. In buildings from before 2000, suspect materials are identified with a survey before removal so they can be handled correctly.
- In England and Wales, cutting away a chimney breast attached to a party wall is notifiable work under the Party Wall etc. Act 1996. Notice must be served on the neighbour before work begins, and their response decides whether party wall surveyors need to be appointed.
- In terraces and semis the chimney stack usually serves both houses, with flues from each side rising together. You can generally only alter your own side, and the work must not weaken your neighbour's breast or flues, which is why party wall procedures often apply.
- 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.
- Once the breast is gone, the wall behind it is often rough, sooty or uneven. It is cleaned back, dubbed out where needed and plastered flat, and the floor where the hearth sat is filled level to meet the surrounding boards or screed.
How the job runs in Portslade
Survey in Portslade
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to Brighton & Hove City Council, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.
How much should I budget in Portslade?

| Through-lounge knock-through | £2,800–£6,150 | Wall between front and back reception rooms, steel beam, approvals, plastering and floor infill |
| Party wall surveyor (agreed surveyor, per neighbour) | £1,000–£2,250 per neighbour | Schedule of condition and award where a neighbour dissents; serving notice alone, where the neighbour consents, costs far less (England and Wales only) |
| Structural calculations for a beam | £280–£840 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for prices in the South East (+12%) and are rounded. How these figures are worked out.
Approvals in Portslade
For Portslade, building control is provided by Brighton & Hove City Council, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
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 Portslade: your questions
How much does chimney breast removal cost in Portslade?
As a guide, budget £1,700–£3,350 including VAT for chimney breast removal (ground floor) in Portslade, 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.
Can you work on older or listed homes in Portslade?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
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.
Can I remove a chimney breast downstairs and keep the fireplace upstairs?
Usually, as long as the upstairs breast and its flue stay intact and are carried on a support the engineer designs for that load. Building control must approve the arrangement. If the upstairs fireplace has a gas fire, any work on it or its supply must be carried out by a Gas Safe registered engineer.
What if my chimney breast was removed without support?
Get it checked by a structural engineer as soon as possible. If the upper breast or stack has no adequate support, it may need propping straight away. A support can usually be fitted retrospectively, and in England and Wales a regularisation application to the local authority can be used to get the unauthorised work approved.
Do you also work near Portslade?
Yes. We also cover nearby towns including Hove, Brighton, Worthing and Rottingdean.
