Chimney Breast Removal Maidenhead

A chimney breast carries the brickwork above it, so removing one at ground floor leaves the stack overhead needing support. That is usually a steel beam on padstones, or gallows brackets bolted to sound brickwork only where the engineer and building control accept them, and the structural engineer we appoint decides which. We build to the calculations issued and never write them. This page covers the consent route, the charge and the roofline question in Maidenhead.

For Maidenhead, on London-derived ranges 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; Berkshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Maidenhead.

How the job runs

1. Free site survey at your Maidenhead address: which floors the breast runs through, a shared stack, any live flue.
2. The engineer we appoint designs the support, and the work is registered with Royal Borough of Windsor and Maidenhead building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
3. The floor above is propped and the breast comes down in courses from the top; what remains sits on the support the engineer specified.
4. Building control inspects the support before it is covered. We make good, and the completion certificate follows.

The application goes on the council's own forms, not the Planning Portal

The Royal Borough of Windsor and Maidenhead no longer accepts building regulations applications through the Planning Portal. Applications must be made using the council's own online forms. If you have used the Portal for work in another borough, that route is closed here, and a notice sent the wrong way is a delay rather than a submission. We make the application for you and keep the reference.

The published charge for a chimney breast is category C3

The council's building control charge category C3 covers structural alterations of a single beam or chimney breast removal. From 1 April 2026 the full plans charge is £300.00 with inspection included, a building notice is £345.00, and regularisation of work already done is £431.25, all inclusive of VAT at 20 per cent. Regularisation is what you pay when a breast came out without a notice.

On the build cost, indicative London ranges, MyBuilder and Checkatrade, 2026, put a chimney breast removed on one floor at £2,200 to £3,250 where a steel beam is used, and £1,500 to £2,500 where gallows brackets are accepted. Removal across two floors runs from £3,000 to £5,000. Which of those applies is the engineer's decision rather than a preference.

The design code names retained chimneys in the Boyn Hill character area

Code CA4.03 of the Maidenhead design code states that where there is a presence of Victorian dwellings in the Boyn Hill character area, building extensions and conversions should retain as much original feature and detailing as possible. It names a retention of timber window frames and a consistent roofline with retained chimneys. Removing a breast internally while leaving the stack and pots in place answers that.

The code describes the Ray Mill character area as late Victorian and early Edwardian two to three storey villas with tiled roofs and ornate chimneys, with facade materials largely red brick, stucco or a mix. Where the stack is part of the elevation, the support design has to hold it up rather than take it down. We price both options so the choice is visible.

Local chimney brickwork is what any gallows brackets have to bolt into

The council's Altwood Road conservation area appraisal records the principal building material there as the orange red brick typical of this part of Berkshire, and records the chimneys as tall brick built structures. Gallows brackets only work where the brickwork they fix into is sound and thick enough. A tall stack adds load and lengthens what is being carried above the removal.

That is why the survey comes before the price rather than after it. We expose enough of the breast and of the brickwork above to let the engineer judge whether a steel beam, now the usual route, is needed or brackets would be acceptable to the engineer and building control. Where a beam is used, the padstones and bearings are designed with it, and the inspection sequence follows from that.

• Soot and debris contained with screens and sheeting
• Building control notification and inspection sign-off
• Bedroom breast removal to reclaim usable floor space
