Chimney breast removal with gallows bracket or beam support in Bishop's Stortford. Trusted, professional, 30+ years' hands-on experience.
Removing a chimney breast means supporting whatever is left above it, or taking the stack out completely, and proving that support to building control. We appoint the structural engineer for the calculations, whether the design uses gallows brackets or a steel beam. In the Bishop's Stortford Conservation Area there is a planning question first, and it is an unusual one. This page explains it.

The householder Article 4 direction qualifies every withdrawn class with the words: to elevations or areas facing or visible from a highway, open space or waterway, except Class G. Class G is the installation, alteration or replacement of a chimney, flue or soil and vent pipe on a dwellinghouse.
Because Class G is carved out of that qualification, it is the single class withdrawn without the visibility test. It applies to a rear or hidden stack as much as to a front one. A chimney at the back of a house in the conservation area is not outside the direction simply because nobody can see it from the road.
East Herts states on its conservation areas page that, with the exception of chimneys, works that would not be visible from the public realm are not affected by the Bishop's Stortford Article 4 directions. Chimneys are the stated exception, not an edge case somebody has read into the wording.
District Plan Policy HA4 supplies the test that is then applied. It states that development proposals, including minor development under an Article 4 direction, will be expected to preserve surviving architectural features identified as being significant to the character or appearance of the area.
It records that selected chimneys, windows and other architectural detailing could in some cases only be protected by removing permitted development rights through an Article 4 direction. Prominent chimneys with pots are described as a recurring character feature of the town's 19th and early 20th century houses.
The appraisal even records individual losses. At nos. 56 to 60 Warwick Road, described as three detached 20th century houses, it notes that the chimney has been removed from no. 56 while its two neighbours keep theirs. That level of detail is a fair warning about what an application here is judged against.
A chimney breast removal in Bishop's Stortford is a planning question before it is a building one, because the chimney class in the Article 4 direction applies whether or not the stack can be seen from the road. That gets settled first. The structural route is then decided by the engineer we appoint: gallows brackets where they are accepted, or a steel beam where they are not. We build to those calculations, coordinate the building control application and the inspections, and make good afterwards.

FAQ
What sits behind the walls drives it far more than the address does. We survey the CM23 property, confirm the load path, and only then price chimney breast removal for your Bishop's Stortford home. Older stock across Bishop's Stortford adds making good, and awkward access adds labour, so both are itemised rather than absorbed. GS Renovation would rather explain a Bishop's Stortford figure than defend it later on site, so ring 07472 424 226 or email info@gsrenovationltd.co.uk first. 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.
Structurally yes, with the retained breast carried on a support the engineer designs. On the planning side the question narrows to whether anything happens to the chimney or the flue itself. Leaving the stack, the pots and the flue untouched keeps the work outside the Class G control, because that class bites on installation, alteration and replacement. Where the stack comes down as well, it is a different conversation with the council. We fix which of the two you want at survey.
It has to stay supported, weathertight and working, and that is designed rather than improvised. A shared stack is a party structure, so notice under the Party Wall etc. Act 1996 comes before the work. The conservation area appraisal picks out tightly knit terraces such as Sidney Terrace, where houses share fabric of exactly this kind. The engineer we appoint designs the support for what remains, and the roof and flashing detail is agreed before anything is opened up.
It can be. The householder direction withdraws Class C, any other alteration to the roof of a dwellinghouse, on elevations or areas facing or visible from a highway, open space or waterway. A patch on a front slope therefore raises a question that a patch on a hidden rear slope may not. Matching the slate or tile matters to how it is judged. We set out which slope is affected, and what the making good will look like, with the quotation.
Assume it does until it has been checked. Class G covers the installation of a chimney or flue on a dwellinghouse, not only its removal, and the visibility limit that qualifies the other classes does not apply to it. A twin wall flue on a rear wall is caught by that wording as much as one on the front. The appliance and the flue also need building control involvement. Both are answered before the room is finished, not after.
Yes, because the support for whatever remains above has to be checked by someone independent. East Herts does not run its own building control service. It is delivered by Hertfordshire Building Control Limited, owned by East Herts with seven other Hertfordshire authorities, and staffed by 48 surveyors, 36 of them professionally qualified. We make the application and book the visit while the brackets or beam and their bearings are still visible.
