Wall removal is taking out an internal wall to open up rooms; where the wall is load-bearing, a steel beam sized by a structural engineer is installed on padstones to carry the weight above, with the work approved by building control.
Every house in Finchley is a little different, so we never price removing a wall from a brochure. We look at the structure, access and existing finishes first, then put in writing a fixed figure for the scope we settle on. As a rough steer, homeowners in London should budget £3,900–£10,500 including VAT, with work typically taking 1–3 weeks including making good.

Building in Finchley
London's housing is dominated by Victorian and Edwardian terraces, often in yellow London stock brick, with Georgian terraces in central districts and mansion blocks across many inner areas. Outer boroughs have large belts of interwar semis, and there are extensive post-war council estates. Many houses have been split into flats, and conservation areas are widespread.
Terraces suit side-return extensions and rear dormer loft conversions; interwar semis commonly take hip-to-gable lofts. Shared party walls, restricted parking and conservation rules often shape the plans and the programme.
So when we survey a Finchley property for removing a wall, the first step is working out how it was built and what has been changed since.
Planning and building rules in Finchley
The notes below cover England, which is where Finchley sits. Rules change and every property is different, so we speak to the council before pricing your job.
Removing an internal wall does not need planning permission in England unless the house is listed.
If the wall is load-bearing, Building Regulations approval is needed, with a structural engineer’s calculations for the steel beam and padstones. Where the beam bears on a shared wall, the Party Wall etc. Act 1996 applies.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
From survey to handover
Free site survey
A free survey comes first. It gives us what we need to price removing a wall properly, including dimensions, existing materials and access for deliveries, and gives you the chance to ask anything you like.
Written quote
Next you receive a written quote with a fixed price for the agreed specification. It lists what is included, what is not, and how payments are staged, so you can compare it properly.
Booking the work
We handle the paperwork side: checking whether planning permission or building control approval is needed, submitting applications where they are, and scheduling the trades and materials around your dates.
Finish and handover
Work goes ahead as scheduled and you deal with one contact throughout. When the last trade leaves, we clear and clean the site, talk you through what has been done and pass on any certificates and care instructions.
What you can expect from us
Frequently asked questions
Can I have a beam that does not show?
A flush or hidden beam sits within the depth of the ceiling so there is no visible downstand, giving a clean, open look. It is possible where the floor joists can be connected into the side of the beam, which takes more steel and labour. It costs more than a standard beam below the ceiling. The engineer confirms whether it suits your house.
What happens to pipes and cables in the wall?
Pipes, cables and radiators in a wall being removed must be rerouted before demolition. Electrical work is done and certified by a qualified electrician, and pipework is diverted by a plumber, usually through the ceiling void or floor. We identify services during the survey and include rerouting in the quote, so there are no surprises once work starts.
How do I know if a wall is load-bearing?
A wall is load-bearing if it carries weight from above, such as floor joists, another wall, the roof or a chimney. Clues include joists running across the wall rather than alongside it, and walls lined up with walls on the floor above. Brick or block walls are often structural but not always. We check from above and below during the survey, and an engineer confirms the design.
Do you cover Golders Green, Muswell Hill and Cricklewood?
Yes. As well as Finchley, we cover Golders Green, Muswell Hill and Cricklewood and the rest of London. Our coverage is UK-wide, so the process is the same wherever you are: a free site survey, a quote in writing that fixes the price for the agreed scope, and one point of contact while the work is planned and carried out.
Can you combine removing a wall with other work?
Yes. Because we manage several trades under one contract, we can plan removing a wall alongside other work on your Finchley home, such as new windows with rendering, or a kitchen refit with an extension. Combining jobs can reduce repeat set-up such as scaffolding, skips and access, and every element is listed and priced in the same written quote.
