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.

In London, we price removing a wall against our guide for London, £3,900–£10,500 including VAT, then adjust it once we have surveyed your home. We work across Brent, Islington, Westminster and Bexley and the rest of the county or region. Planning and building control requirements follow the rules for England, and we look into your property's position before a written quote is sent.

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.

London Clay shrinks and swells with the seasons, and street trees close to houses can contribute to movement, which affects foundation design.

Planning and building rules in London

Each UK nation sets its own consent rules, and London is in England. What follows is a plain summary; we check the specifics for your property with the council before pricing anything.

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.

The four stages

  1. A visit to your home

    It starts with a survey at the property, free of charge. We check condition, access and services, ask how you want the finished result to look, and answer any questions you have about removing a wall.

  2. Your fixed price

    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.

  3. Getting ready

    Once you accept, we agree start dates, order materials and deal with any planning, building control or neighbour notices the job needs. You'll know who is coming and when before work begins.

  4. Finish and handover

    On site, the agreed plan is followed and any change is put in writing first. At completion we do a final clean, go through the snagging list with you and leave you with the relevant documents.

Frequently asked questions

Do I need building regulations approval to remove a wall?

Removing a load-bearing wall needs building regulations approval anywhere in the UK, and in Scotland a building warrant. A structural engineer calculates the beam and supports, and building control inspects the work. Removing a non-structural wall may still need approval if it affects fire escape routes, such as opening a hallway into a living room. We handle the applications and inspections.

How disruptive is removing a wall?

Removing a wall is dusty and noisy, but the most disruptive part is short, usually one to three days for propping, demolition and installing the steel. We seal doorways with dust screens, protect floors and keep a safe route through the house. Making good, plastering and floor repairs follow over the next week or two. Most people stay at home throughout.

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.

Who do I deal with during the job?

One point of contact manages your project from survey to handover. They schedule the trades working under our contract, keep you updated on progress, and are the person to call with any question. You don't need to coordinate builders, electricians or decorators separately, because that is part of what we do.

What happens at the survey?

We visit your home at a time that suits you, look at the area involved, take measurements and check access, condition and any services that might be affected. We talk through what you want from removing a wall, explain the options and answer questions. There is no charge and no obligation; afterwards we send a written quote.
