What chimney breast removal involves in Formby

For homes in Formby and the L37 and L38 districts, we handle chimney breast removal from survey to sign-off. It sits about 10.9 miles from Liverpool, which we also cover. The beam is sized by a structural engineer and inspected before it is boxed in.

Chimney breasts take up a surprising amount of room, especially in the kitchens and bedrooms of older terraces and semis. Removing one is common, but it is structural work: the breast usually continues upstairs and up through the roof, and in terraces the stack is often shared with the house next door.

What to expect

  • 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.
  • Some owners remove breasts in the loft to make space for a conversion while keeping the stack on the roof. That leaves the stack carried at loft level on steel or another support, which the engineer must design and building control must approve before work starts.
  • The price depends on how many floors the breast spans, whether the stack is kept or removed, the support method the engineer specifies, roof and scaffold work, and how much rubble needs taking away. Each is listed separately in the quote.
  • 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.
  • Gallows brackets are steel angle brackets fixed into the wall to hold a breast above. They are often not accepted where the remaining masonry is heavy or sits against the neighbour's breast, so the engineer and building control decide which support method is suitable.

Four stages, one team

  1. Free visit

    A short visit to Formby to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

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

  4. Steel in, made good

    On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Approvals in Formby

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 Sefton 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.

Questions about chimney breast removal in Formby

Can I stay at home while the work is done in Formby?

Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.

How much does chimney breast removal cost in Formby?

As a guide, budget £1,450–£2,900 including VAT for chimney breast removal (ground floor) in Formby, based on published UK cost guides adjusted for prices in the North West (-4%). 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.

Should I remove the chimney stack as well?

It often makes sense if the breast is coming out on every floor, because then nothing is left to support. It needs scaffolding and roof repairs, and in terraces the stack is often shared, so your side may not be removable without affecting your neighbour's. The engineer and building control confirm what is possible.

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.

What is included in a chimney breast removal quote?

The itemised written quote covers the survey, engineer's calculations, building control, any party wall notices, temporary support, the steel or other support specified, removal and waste, venting or capping, and plastering and floor making good. Scaffolding and roof work appear as separate lines where the stack is involved, and the price is fixed in writing once the scope is agreed.
