Chimney breast removal in Llandudno: how it works
Our chimney breast removal service in Llandudno covers everything from the first visit to the completion paperwork. We also cover the surrounding towns and villages in Conwy. Postcode districts we cover here include LL30 and LL31.
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.
Worth knowing before you start
- 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.
- Older fireplaces sometimes contain asbestos in flue linings, fire surrounds, hearth boards or heat-resistant panels. In buildings from before 2000, suspect materials are identified with a survey before removal so they can be handled correctly.
- 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.
- 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.
- Chimney brickwork is heavy and dirty. Even a single breast produces a lot of rubble and soot, so a skip or waste collection is planned in advance, and floors, stairs and furniture along the route out are protected.
Four stages, one team
Look and measure
We check the wall, the span you want and what the wall is carrying, and photograph anything the engineer needs to see.
Design and price
Calculations come back from the engineer and we confirm your fixed written price, line by line.
Building control
We submit the application or notice to Conwy County Borough Council under the Building Regulations as they apply in Wales, before work starts.
Fit, inspect, finish
The work is propped and the steel installed and packed tight. After inspection the opening is boxed, plastered and left clean.

Building rules for Llandudno
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Conwy County Borough Council handles building control for Llandudno. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Chimney breast removal in Llandudno: your questions
What happens at the survey visit in Llandudno?
We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.
Do you cover Llandudno for chimney breast removal?
Yes. We carry out chimney breast removal in Llandudno and the LL30 and LL31 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
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.
Are gallows brackets allowed for chimney breast support?
Sometimes, but not always. Gallows brackets are used for lighter loads in certain situations, yet many building control bodies will not accept them where the remaining breast is heavy, sits on a party wall or carries the neighbour's flues. The structural engineer proposes a method and building control decides whether it is acceptable.
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 much does chimney breast removal cost in Llandudno?
As a guide, budget £1,350–£2,750 including VAT for chimney breast removal (ground floor) in Llandudno, based on published UK cost guides adjusted for prices in Wales (-9%). 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.
