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.
West Sussex is part of our UK-wide coverage for removing a wall. Places we cover include Crawley, Worthing, Bognor Regis and Littlehampton, and we travel to smaller communities across the area as well. Since your property is in England, the relevant planning and building rules are the ones set there. In the South East, budget around £3,400–£9,000 with VAT; the figure is confirmed after a survey that costs you nothing.

How much does removing a wall cost in West Sussex?
Below is a breakdown of typical costs for removing a wall in West Sussex. Because rates in the South East are about 12% above the national guide, the overall guide comes to £3,400–£9,000, including VAT. Size, materials and access move the figure, and a free-of-charge survey settles it.
| Type of job | What it usually involves | Guide in West Sussex |
|---|---|---|
| Non-load-bearing wall | Removing a stud or block partition and making good walls, ceiling and floor. | £900–£2,200 |
| Load-bearing wall up to 4m | A typical kitchen-diner knock-through with one steel beam, calculations and building control. | £3,400–£9,000 |
| Wide or complex opening | Openings over 4m, posts, flush beams or chimney breast removal. | £9,000–£18,000 |
The main things that change the figure:
- Opening width and the load the wall carries
- Beam size, posts, flush fixing and padstone details
- Floor and ceiling repairs where the wall stood
- Engineer, building control and any party wall costs
What do you get?
- 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
Housing across West Sussex
Chichester has Georgian brick streets, Downland villages use flint and brick, and Horsham stone slabs cover some older roofs. Worthing and Bognor Regis have interwar and post-war bungalows and semis, Crawley was planned as a post-war new town, and Wealden villages to the north feature tile-hanging and timber framing.
Bungalows commonly suit loft conversions and extensions; new-town homes often take window, roofline and cladding renewal. Flint and stone properties need lime repointing, and coastal homes may need external decorating more often.
Coastal towns face salt-laden south-westerly winds, while Wealden clay inland can shrink and swell with the seasons.
Planning and building rules in West Sussex
Because West Sussex falls under England's rules, the guidance below is the version relevant to you. Before sending a price, we check your property's position with the council.
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
We look at the job
First, someone visits your home in West Sussex to see the space, take measurements and note anything that could affect the work, such as access or the condition of what is there. There is no charge for this visit.
Quote in writing
After the survey we send a quote for removing a wall that fixes the price for the scope we've agreed. If you want to change materials or scope, we revise it in writing before anything is booked.
Booking the work
Next comes planning the work itself. We set a start date that suits you, line up the right trades, and make sure any approvals for removing a wall are in place before the first day on site.
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.
What you can expect from us
Frequently asked questions
Is the price fixed?
Yes, for the specification we agree. Your written quote sets out exactly what is included at a fixed price. It only changes if you ask for something different, or if a problem the survey could not reasonably reveal later needs extra work. In either case we explain the change and confirm it in writing before going ahead.
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.
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 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.
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.
