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.
Anyone planning removing a wall in Purley wants three things: a clear price, a realistic timetable and a tidy job. We publish a guide of £3,900–£10,500 including VAT for London up front, explain that work normally takes 1–3 weeks including making good, and confirm both in writing after a free survey of your property.

Building in Purley
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.
Whatever era your Purley home dates from, we plan removing a wall around how it is actually built rather than a one-size-fits-all specification.
Planning and building rules in Purley
For anyone in Purley, the relevant framework is England's. The summary below is general, so we always contact the council about your address before putting a price in writing.
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.
How does the job run?
We look at the job
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.
Your fixed price
You get the price in writing, itemised so you can see where the money goes. As long as the specification stays the same, that is the price you pay for removing a wall.
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.
On site to finish
The job proceeds in the order set out in the programme, with dust and debris kept under control. Finally we tidy away, inspect the work together and pass the finished project over to you with its paperwork.

Questions about removing a wall in Purley
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.
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 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.
Do I need planning permission in Purley?
It depends on the work, the size of the project, your property type and whether the building is listed or in a conservation area. Purley is in England, so England's rules apply. Many smaller jobs need no planning application, but some still need building control approval. We check what applies to your address before quoting.
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.
