About our load-bearing wall removal service in Barnet
We carry out load-bearing wall removal in Barnet, covering the EN4, EN5, N12, N20 and NW7 postcode districts. We also cover the surrounding towns and villages in London. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
Most homes built before the 1970s have at least one internal wall that carries the floor joists, a wall upstairs or part of the roof. Taking it out is very doable, but the weight it carries has to go somewhere. A steel beam picks that load up and passes it down through padstones into walls or columns that can take it.
Worth knowing before you start
- Most single-wall removals in a typical house take two to five working days on site for the structural part. Plastering, drying out and decorating follow on, and building control visits fit around those stages.
- The beam size depends on the span, what sits above and how the ends are supported. Two walls that look the same can need very different steel, which is why every beam is sized from calculations rather than guessed.
- Steel beams in homes usually need fire protection. That is often fire-rated plasterboard boxing, which also gives a neat finish, or intumescent paint where the steel is left on show.
- Temporary works matter as much as the beam. Props, spreaders and needles carry the house while the wall is out, and they are positioned so the floor below can take them too.
- Older homes can hide surprises such as weak lime mortar, timber lintels or a wall with no proper footing. Where the engineer needs something extra, we price it before any work starts rather than after.
How the job runs in Barnet
Survey in Barnet
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 a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
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.

Building control and neighbours in Barnet
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 the local council's building control team 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.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Load-bearing wall removal in Barnet: your questions
Can you work on older or listed homes in Barnet?
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.
Do you also work near Barnet?
Yes. We also cover nearby towns including Hadley Wood, Potters Bar, Borehamwood and Finchley.
What happens if the wall is shared with my neighbour?
In England and Wales, cutting into a party wall to take the end of a beam is covered by the Party Wall etc. Act 1996, and notice must be served on the neighbour before work starts. Scotland and Northern Ireland have no equivalent Act, so the title deeds and the general law apply instead.
What does the price include?
Our written quote is itemised, so you can see the calculations, building control fees, propping, steel, padstones, labour, fire protection and making good set out line by line. The price is fixed in writing once the layout and scope are agreed.
Who sizes the steel beam?
A structural engineer. They look at the span, the loads from floors, walls and roof above, and the bearings at each end, then specify the beam, padstones and any columns. We arrange those calculations, or work to calculations you already have.
