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 remove internal walls to create open-plan kitchens, living spaces and wider openings. Our free site survey and written quote checks whether the wall is load-bearing, what it supports above, where the beam ends will sit, and what services run through it. We arrange structural calculations, building control approval and, where needed, party wall notices. Wall removal suits people who want a kitchen-diner, more light or better flow through the ground floor. On site we prop the structure safely, remove the wall, install the steel and padstones, and then make good with plasterboard, plaster and flooring repairs so the room is ready for decoration.
What’s included?
- Survey to establish what the wall supports and where loads go
- Structural engineer's calculations and beam specification
- Building control application and inspections
- Temporary propping and dust protection during the work
- Wall taken down and waste removed from site
- Steel beam installed on padstones and packed tight
- Beam boarded or treated for fire protection
- Plastering, flooring repairs and making good ready for decorating
Which options can you choose from?
How much does removing a wall cost?
Most jobs fall between £3,000–£8,000 for removing a load-bearing wall of about 3–4m with a steel beam, including engineer and building control, including VAT at 20%. The table shows three typical levels of work; the figures are national guides, confirmed in writing after a free site survey.
| Type of job | What it usually involves | Guide price |
|---|---|---|
| Non-load-bearing wall | Removing a stud or block partition and making good walls, ceiling and floor. | £800–£2,000 |
| Load-bearing wall up to 4m | A typical kitchen-diner knock-through with one steel beam, calculations and building control. | £3,000–£8,000 |
| Wide or complex opening | Openings over 4m, posts, flush beams or chimney breast removal. | £8,000–£16,000 |
What affects the price?
- Opening width and the load the wall carries
- Beam size, posts, flush fixing and padstone details
- Services in the wall that need rerouting
- Floor and ceiling repairs where the wall stood
- Engineer, building control and any party wall costs

Do you need planning permission for removing a wall?
Removing a load-bearing wall needs building regulations approval anywhere in the UK, with structural calculations and inspections by building control, and in Scotland a building warrant. Work on a shared wall may need party wall notices in England and Wales.
England
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.
Wales
Removing an internal wall does not need planning permission in Wales unless the building is listed.
Load-bearing walls need Building Regulations approval and structural calculations; the Party Wall etc. Act 1996 applies to shared walls.
Scotland
Removing an internal wall does not need planning permission in Scotland unless the building is listed.
Removing a load-bearing wall needs a building warrant and a structural engineer’s design. In tenement flats, the common parts and other owners’ interests also have to be considered.
Northern Ireland
Removing an internal wall does not need planning permission in Northern Ireland unless the building is listed.
Structural alterations need building control approval and engineer’s calculations. There is no Party Wall Act in Northern Ireland.
Rules change and every property is different, so we check the planning history and constraints for your address before we quote.
How long does it take?
Typical time on site: 1–3 weeks including making good. Lead times for materials, drawings and approvals come before that and are set out in your written quote.
How does the job run?
Free site survey
We visit, measure up, look at access and the condition of what’s there, and talk through options and budget with you.
Written quote
You get a written quote with a fixed price for the agreed specification, what’s included, the payment stages and a likely start window.
Plan and prepare
We sort drawings, approvals and materials, agree dates with you and explain what to expect each week before work starts.
Build and hand over
The work is carried out, checked and cleared away. We walk round it with you and pass on certificates and product details.
Wall removal and steel beams: frequently asked questions
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 £3,000–£8,000, 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.
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 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.
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.
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.
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.
