Planning chimney breast removal in Derby

We carry out chimney breast removal in Derby, covering the DE1, DE3, DE21, DE22 and DE23 postcode districts. We also cover the surrounding towns and villages in Derbyshire. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

We cover the survey visit, structural calculations from a qualified engineer, building control, party wall notices through a party wall surveyor where needed, temporary support, removal, the steelwork and making good. Whether you are taking out the ground-floor breast only or the full height, the itemised written quote shows each stage.

Things to plan for

  • A chimney closed off at both ends can trap moisture and cause damp patches on the walls. Where part of a flue remains, a vent at room level and a ventilated cap on the pot keep air moving through it.
  • Once the breast is gone, the wall behind it is often rough, sooty or uneven. It is cleaned back, dubbed out where needed and plastered flat, and the floor where the hearth sat is filled level to meet the surrounding boards or screed.
  • A flue still serving a gas fire, boiler or wood burner cannot be removed until that appliance is disconnected and an alternative arranged. Work on any gas appliance or pipe must, by law, be done by a Gas Safe registered engineer.
  • Removing a ground-floor breast with steel support typically takes two to four working days. Full-height removal including the stack and roof repair takes longer and depends on scaffolding, roofing access and the weather.
  • In England and Wales, cutting away a chimney breast attached to a party wall is notifiable work under the Party Wall etc. Act 1996. Notice must be served on the neighbour before work begins, and their response decides whether party wall surveyors need to be appointed.

From survey to sign-off in Derby

  1. Survey in Derby

    We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.

  2. Engineer's design

    A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.

  3. Building control

    We submit a building notice or full plans application to Derby City Council, so approval is in place before the wall is touched.

  4. Install and sign-off

    Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Derby

In England, taking out a load-bearing wall or putting in a beam is building work under the Building Regulations 2010. It needs approval from building control, either Derby City Council or a registered building control approver, through a full plans application or a building notice. Part A covers the structure and Part B covers fire safety, which is why steel in homes is usually fire protected.

Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Chimney breast removal in Derby: your questions

Do I need a party wall agreement for chimney breast removal in Derby?

Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.

How much does chimney breast removal cost in Derby?

As a guide, budget £1,450–£2,950 including VAT for chimney breast removal (ground floor) in Derby, based on published UK cost guides adjusted for prices in the East Midlands (-2%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.

Can I remove a chimney breast downstairs and keep the fireplace upstairs?

Usually, as long as the upstairs breast and its flue stay intact and are carried on a support the engineer designs for that load. Building control must approve the arrangement. If the upstairs fireplace has a gas fire, any work on it or its supply must be carried out by a Gas Safe registered engineer.

Do I need building regulations to remove a chimney breast?

Yes. Removing all or part of a chimney breast is structural work. In England it needs building regulations approval through a full plans application or building notice, and in Wales an application under the Welsh regulations; in Scotland a building warrant is needed before starting; in Northern Ireland an application goes to council building control. We prepare and submit this with the engineer's calculations.

How long does chimney breast removal take?

A ground-floor breast with a steel beam supporting the masonry above usually takes two to four working days, including propping, fitting the steel, removing the brickwork and basic making good. Full removal from ground floor to roof takes longer because of scaffolding, roofing work and weather, and plaster needs time to dry afterwards.
