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.
We offer removing a wall across London, and Streatham is one of the places we cover, along with nearby Mitcham, Brixton and Wimbledon. Before anything is agreed we visit, check the existing structure and talk through your options. You then receive a written quote setting out the full scope; for most homes in London it sits within £3,900–£10,500 including VAT.

Homes in London
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.
For removing a wall in Streatham, this means checking things like wall construction, roof structure and existing services before we put a figure on paper.
Permissions for removing a wall in Streatham
England, Wales, Scotland and Northern Ireland each handle planning a little differently. Streatham comes under England, covered below, and we raise any questions with the council before your quote is finalised.
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
We arrange a free site survey on a date convenient to you. We measure up, look at the existing structure and access, and discuss your plans for removing a wall so the price reflects your home.
Written quote
We turn the survey notes into a written quote. The price is fixed for the specification we agree, and the document sets out materials, scope and payment stages in plain language.
Getting ready
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.
On site to finish
During the work we protect the areas around it and tidy up at the end of each day. Once complete, we check the finish, remove our materials and hand over paperwork such as building control sign-off where it applies.
Why homeowners choose us
Common questions
How long will removing a wall take?
On a typical home, allow 1–3 weeks including making good. Larger projects, older buildings and extra work found once things are opened up can extend that, while simpler jobs may be shorter. Your quote includes an estimate of time on site, and your point of contact keeps you updated on the programme as the work progresses.
How much does it cost to remove a load-bearing wall?
Removing a load-bearing wall of about 3–4m with a steel beam typically costs £3,900–£10,500, including structural calculations, building control and making good. A non-load-bearing partition costs much less. As a rough guide, allow around £600–£1,600 per metre of opening plus fixed costs for the engineer, approvals and propping. Wider openings, posts and flush beams cost more. We confirm a fixed price after the survey.
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 Streatham 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.
What is a steel beam and why is it needed?
A steel beam, often called an RSJ, is a strong steel section installed where a load-bearing wall used to be, so the weight above is carried across the opening to the walls at each end. It sits on padstones that spread the load. The size depends on the span and the load, which a structural engineer calculates. The beam is then boxed in or plastered.
Does the Party Wall Act apply to wall removal?
The Party Wall etc. Act 1996 applies in England and Wales only. Removing an internal wall usually does not involve it, but if the beam bears into a wall shared with a neighbour, as is common in terraced and semi-detached houses, you must serve notice first. Scotland and Northern Ireland have no equivalent Act. We tell you during the survey whether notices are needed.
