Planning chimney breast removal in Ceredigion

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.

We carry out chimney breast removal throughout Ceredigion, for homeowners, landlords and builders who need the structural part done properly. We work in Aberaeron, Aberystwyth and Lampeter and the surrounding villages. You get an itemised written quote that shows the calculations, approvals, steel, labour and finishing as separate lines.

Worth knowing before you start

  • The price depends on how many floors the breast spans, whether the stack is kept or removed, the support method the engineer specifies, roof and scaffold work, and how much rubble needs taking away. Each is listed separately in the quote.
  • 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.
  • 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.
  • 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.
  • 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.

What happens, step by step

  1. Free visit

    A short visit to Ceredigion to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit the application or notice to Ceredigion County Council under the Building Regulations as they apply in Wales, before work starts.

  4. 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 control and neighbours in Ceredigion

Welsh building regulations treat beams and new openings as controlled building work. We apply to Ceredigion County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.

Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Chimney breast removal in Ceredigion: your questions

Do you cover Ceredigion for chimney breast removal?

Yes. We carry out chimney breast removal in Ceredigion. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

Can you work on older or listed homes in Ceredigion?

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.

Are gallows brackets allowed for chimney breast support?

Sometimes, but not always. Gallows brackets are used for lighter loads in certain situations, yet many building control bodies will not accept them where the remaining breast is heavy, sits on a party wall or carries the neighbour's flues. The structural engineer proposes a method and building control decides whether it is acceptable.

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.

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.

Should I remove the chimney stack as well?

It often makes sense if the breast is coming out on every floor, because then nothing is left to support. It needs scaffolding and roof repairs, and in terraces the stack is often shared, so your side may not be removable without affecting your neighbour's. The engineer and building control confirm what is possible.

How much does chimney breast removal cost in Ceredigion?

As a guide, budget £1,350–£2,750 including VAT for chimney breast removal (ground floor) in Ceredigion, based on published UK cost guides adjusted for prices in Wales (-9%). 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.
