Load-bearing wall removal in Conwy: how it works
Load-bearing wall removal means taking out a wall that holds up floors, roof loads or walls above it, and replacing that support with a steel beam sized by a structural engineer. The beam sits on padstones at each end, the weight above is held on temporary props while the wall comes out, and building control inspects the finished work.
Homes across Conwy range from Victorian terraces to post-war semis and newer estates, and load-bearing wall removal looks different in each. That includes Colwyn Bay, Abergele and Llandudno, plus smaller towns and villages nearby. We plan the steel, the temporary support and the approvals around the building, then fix the price in writing once the scope is agreed.
Worth knowing before you start
- Each end of the beam needs a solid bearing. Padstones spread the point load into the masonry below, and if the wall underneath is weak the engineer may call for a steel column or a new pad foundation instead.
- Homes built before 2000 may contain asbestos in textured ceilings, boxing or old boards. Where there is a risk, a survey of the area being disturbed is arranged before the wall comes out.
- Expect some dust and noise for a day or two while the wall comes out. We screen the work area, protect floors and sweep up daily, and the rest of the house usually stays usable throughout.
- Cables, pipes, radiators and sometimes gas runs pass through internal walls. These are traced at the survey so they can be rerouted by the right trade before or during the work, not discovered halfway through.
- If the wall carries a chimney breast, a wall upstairs and floor joists all at once, the engineer may specify a heavier beam or two beams side by side. The quote reflects that once calculations are back.
Four stages, one team
Survey in Conwy
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.
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.
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.
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.

| RSJ supply and fit (single beam) | £730–£2,280 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
| Temporary works and propping | £140–£460 | Props, spreaders, needles and sole plates for a typical opening, installed and struck |
| Structural calculations for a beam | £230–£680 | Site measure or photos, beam and padstone design and calculations for building control |
Figures include our approximate regional adjustment for prices in Wales (-9%) and are rounded. How these figures are worked out.
Approvals in Conwy
Welsh building regulations treat beams and new openings as controlled building work. We apply to Conwy County Borough Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Local questions answered
Can you work on older or listed homes in Conwy?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
How much does load-bearing wall removal cost in Conwy?
As a guide, budget £1,800–£4,550 including VAT for load-bearing wall removal with steel beam in Conwy, 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.
Can I stay in the house while the wall is removed?
In most cases yes. The work area is screened, floors are protected and the house stays usable, though the rooms either side of the wall will be out of action for a few days and there will be some noise and dust.
Do I need planning permission to remove an internal wall?
Usually not, because internal alterations to a house are not normally development needing planning permission. Listed buildings are different and need listed building consent, and flats normally need the freeholder's or landlord's written consent.
Will the beam show once the job is finished?
It depends on the design. Most beams sit just below the ceiling and are boxed in with plasterboard, leaving a small step. A beam can be set up into the floor void for a flat ceiling, which takes more work, or left exposed and painted where you want an industrial look.
Is a steel beam better than a concrete lintel?
For short openings in some walls a lintel can be enough, but wide openings carrying floors or walls above normally need steel. The engineer chooses whatever does the job properly. Steel is common because it carries a lot of load for its depth.
