Chimney breast removal with gallows bracket or beam support in Slough. Trusted, professional, 30+ years' hands-on experience.
Removing a chimney breast means supporting what is left above it, or taking the stack out entirely. The support is either gallows brackets, where they are accepted, or a steel beam. We appoint the structural engineer, build to the calculations issued, and coordinate the building control side. This page covers what Slough asks for, and the two points people are caught out by.

Slough Borough Council states that changes to an existing building, such as removing a wall or a chimney, will probably need building regulations approval. A chimney breast carries load and forms part of the fire separation, so it is not a job that falls outside the regulations simply because it happens indoors.
Whether gallows brackets are accepted or a steel beam is required is a question for the structural engineer and the inspector, not for the builder. We get the calculation first and price from it, so the figure you are given matches the support that will actually be approved.
Slough Borough Council states that all of the Slough area is covered by smoke control orders, so it is an offence to burn an unauthorised fuel unless it is used in an exempt appliance. That matters if you are removing a breast downstairs and keeping a working fire elsewhere in the house.
It matters again if the plan is to take out one breast now and put an appliance back later. Decide what the flue is for before work starts, because a flue is far easier to keep than to put back.
Slough Borough Council states that applicants are required to comply with the Party Wall Act and other civil laws. It states that notice must be served on the neighbouring occupier if any encroachment beyond the curtilage of the application site is proposed. Where a chimney breast sits on or in a party wall, that duty is live before any brickwork moves.
We are a contractor and not a party wall surveyor, so we do not serve notices and we do not advise either side. We raise it at survey, and we programme the work so that any notice period sits in front of the start date rather than across it.
Slough Building Control asks for site inspection visits to be requested 24 hours in advance, so that it can plan its site visits more effectively. On a chimney breast job the stages worth seeing are the support before it is loaded, and the making good before it is covered.
We make the booking and hold the following trade until the visit has happened. That is the difference between a finished ceiling and a ceiling that has to be opened back up.
A chimney breast removal is decided by what is left above it. We appoint the structural engineer to establish whether gallows brackets are acceptable or a beam is needed, and we build to that answer rather than to a rule of thumb. The building control application goes to Slough Borough Council's own service, and we make it and book the inspections around the support going in. Because a stack may be shared, and because the whole borough sits under smoke control orders, we settle the neighbour question and the flue question before the first brick moves.

FAQ
It depends on the house, which is exactly why the survey comes first. In interwar semis and short terraces with hipped roofs and rear kitchens the reinstatement often outweighs the structural element of chimney breast removal, whereas a newer SL1 property is the other way round. GS Renovation prices the two separately so a Slough client can see the balance. Phasing the work is then possible if the budget needs it. Ring 07472 424 226 and GS Renovation will talk through phasing options for an SL1 home. As a rough guide, chimney breast removal in London costs roughly £1,500 to £2,500 for a single floor where gallows brackets are accepted, or £2,200 to £3,250 where a steel beam is needed, which is the more common route now that LABC has withdrawn its standard gallows detail; two floors run £3,000 to £5,000 (indicative London ranges, MyBuilder and Checkatrade, 2026). Your figure depends on the size, specification and condition of the property, which is why we survey before quoting.
Conservation area consent applies to demolishing a building with a volume greater than 115 cubic metres, so a stack sits below that threshold. The elevation still matters, because the council advises checking the boundary before you design anything inside one of its five conservation areas. At Upton Park the houses are built in brick of three colours, red, yellow and plum, with stucco or colourwashed render dressings. Making good has to match that.
Only with listed building consent, which is a separate application from building regulations approval and carries its own timetable. The revised statutory list of buildings of special architectural or historic interest for the former Borough of Slough was issued on 3 August 1984 by the Department of the Environment. Confirm whether your address appears on it before the room is stripped, because the answer changes the programme rather than just the paperwork.
It changes where the load has to land. Slough Borough Council's Upton Conservation Area Character Survey records the West Villas at Nos 17 to 43 odd as built from 1843 onwards, two storey with gabled attic rooms and half basements. A breast standing over a half basement needs its bearing established below ground floor level before any support is designed. We open up at survey and give the engineer what is there.
Apply for regularisation. Slough Borough Council takes building control regularisation applications for unauthorised work carried out on or after 11 November 1985. It warns that you may be required to uncover certain aspects of the work so it can establish whether it complies, which on a breast means exposing the support in the ceiling. The council also states that compliance is the responsibility of designers, builders and building owners alike.
