Chimney breast removal with gallows bracket or beam support in Hitchin. Trusted, professional, 30+ years' hands-on experience.
Removing a chimney breast means supporting whatever stays above it. On an upper floor the brickwork left in place has to be carried, on gallows brackets where the wall and the engineer allow, or on a steel beam where they do not. We appoint the structural engineer, build to the design issued and arrange the building control inspection. This page sets out what the work involves in Hitchin.

The Article 4 direction over the Hitchin Conservation Area removes permitted development rights for the installation, alteration or replacement of a chimney, flue or soil and vent pipe. Work that would need no application elsewhere therefore needs a full planning application inside that area. It is a question about the chimney itself, so it can catch a scheme that only intended to take the breast out of a room.
We establish whether your address falls inside the Hitchin Conservation Area before anything is priced, and we say plainly if an application is needed. A chimney job that assumed no consent was required, and then met the direction, is a job that stops halfway.
The council's character statement says the simple building forms of Benslow Lane and Trevor Road are enlivened by substantial brick stacks with original clay chimney pots, important in views along each street. In the Hitchin Hill Path Conservation Area the statement records red or brown brick, stucco, steeply pitched slated or tiled roofs, original sash windows with rubbed brick voussoirs, and decorative brick chimney stacks.
That has a practical consequence for your scheme. Taking the breast out of a room does not have to mean taking the stack off the roof, and where the stack reads in the street there is a case for keeping it. If it stays, it has to be carried, and that support is what the engineer designs. We set out both routes, with the price of each, before you choose.
Hertfordshire Building Control carries out the local authority building control function in North Hertfordshire, because North Herts Council does not deliver building control in house. So the notice for a chimney breast removal does not go to a council team at Gernon Road. We make the application and book the inspection for the stage when the support is in and still visible.
That sequencing is the whole job. Brickwork left standing above an opening has to be held on something the engineer has sized, and the inspector has to see it before it disappears behind plasterboard. We do not close anything up in advance of that visit.
A chimney breast removal is a support job with a heritage question in front of it. The support question is what carries the brickwork left above the opening, and that is for the structural engineer we appoint, not for us and not for you. Gallows brackets are accepted where the wall and the engineer allow, and a steel beam is the answer where they do not. The difference shows in the price. The heritage question is whether the property sits inside the Hitchin Conservation Area, because the Article 4 direction there covers chimneys and flues. We answer both before quoting.

FAQ
No. The survey is free and carries no obligation, whether the property is in Hitchin or over in Letchworth Garden City. We look at the SG4 address, explain what chimney breast removal would involve in a home of that age, and follow up with a written quotation. If you decide against it, GS Renovation does not chase you. That applies right across Hitchin and the rest of Hertfordshire, so ring 07472 424 226 whenever it happens to suit. 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.
No. North Hertfordshire has two Article 4 directions in the whole district, one over the Hitchin Conservation Area and one over Stockens Green, so the chimney and flue restriction does not extend to the town's other three conservation areas. Butts Close, Hitchin Hill Path and the railway area are separate designations with their own character statements. Conservation area status still applies there, so the effect of the work still counts. We confirm the designation for your address.
It stays, and it has to keep working. A stack on a party line carries flues from both houses, so removing brickwork on one side leaves the neighbour's flue and the shared masonry to be supported and made weathertight. The council's character statement records the substantial brick stacks of Benslow Lane and Trevor Road as important in views along each street. The engineer we appoint designs that support before anything is cut.
Inside the Hitchin Conservation Area, treat it as one. The Article 4 direction there removes permitted development rights for alterations to the roof of a dwellinghouse, as well as for the chimney itself. Both limbs are engaged once the stack comes off and the roof is closed up. Character Area 5 is recorded as having clay tiled roofs with decorative ridge tiles and prominent stacks. We put the question to North Herts Council before the quotation is issued.
It needs ventilating at both ends, or it holds moisture and the damp shows on the breast in the room above. Hertfordshire Building Control gives ventilation, damp proofing and heating as part of its remit, so this is more than good practice. A capped stack with an air path at the top, and an air brick at the base of the retained breast, is what we build. We agree it before the room is closed up.
Only where the masonry itself will take them, which is a decision for the engineer. Brick making in Hitchin, in red and white brick, continued until the early 20th century, and the Hitchin Hill Path character statement records red or brown brick with decorative brick chimney stacks. Locally made brick bedded in lime mortar is not a uniform material. We expose the wall at survey so the engineer decides on the real thing rather than on a photograph.
