Removing a chimney breast means supporting whatever stays above it. On an upper floor the brickwork left in place has to be carried, now usually on a steel beam bearing on padstones, or on gallows brackets only where the engineer and Hertfordshire Building Control accept them. 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.
For Hitchin, 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; Hertfordshire work generally runs below that. GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hitchin.

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

Altering a chimney or flue in the Hitchin Conservation Area needs planning permission
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.
Housing in Hitchin
About 16,130 homes are listed for Hitchin, and the mix is 70% houses to 30% flats, with 69% built after 1945, 16% in 1919 to 1939 and 14% earlier. The shared stack of a semi in Hitchin means a party wall notice before removal, and 28% of homes here are semi-detached.
In Hitchin the stack belongs to the street, not just to the roof
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.
The inspection is booked with Hertfordshire Building Control
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.

Why Hitchin Homeowners Choose GS Renovation
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. A steel beam on padstones is now the usual answer, since LABC withdrew its standard gallows bracket detail in 2024, and gallows brackets are used only where the engineer and building control accept them. 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. GS Renovation Ltd is fully insured and registered in England, company number 14611254.

FAQ
Frequently Asked Questions about Chimney Breast Removal Hitchin
Do you charge for a survey before quoting chimney breast removal in Hitchin?
The survey for chimney breast removal in Hitchin is free, and it is where the figure within £2,200 to £3,250 for one floor on a beam (London-derived) is actually decided. At the SG5 address GS Renovation checks what decides the job: removing one floor or two decides the support. A written quotation follows; if you decide against it, nobody chases you. Ring 07472 424 226 whenever suits.
Does the Article 4 direction reach the Hitchin Railway and Ransom's Recreation Ground Conservation Area?
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.
What happens to the neighbour's flue when a breast is taken out of a terraced house?
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.
Is taking the stack down to roof level a roof alteration for planning purposes?
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.
What happens to a flue that is left in place and no longer used?
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.
Can gallows brackets be used on the brickwork of an older Hitchin house?
Only where the masonry itself will take them, which is a decision for the engineer and building control, and a beam is now the more common route. 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.
