GS Renovation removes load-bearing walls across Bexley, from the 1930s semis around Danson Park to the interwar houses of Welling and Bexleyheath. We take out the wall between kitchen and dining room and install an engineer-sized steel beam to carry the load above.
In Bexley, a complete single opening typically costs £2,500 to £6,500 or more, including the engineer's calculations, the steel beam, propping and making good (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Bexley.

How the job runs
- Free site survey at your Bexley address and an itemised quote.
- The engineer we appoint sizes the beam, and the work is registered with Bexley Council building control or an approved inspector. On a shared wall you serve the party wall notice as building owner; we supply the drawings.
- The floor above is propped, the wall comes out and the beam is set on padstones.
- Building control inspects the steel before it is covered. We make good, and the completion certificate follows.
Removing internal walls in Bexley semis
Bexley's 1930s and interwar houses were built with a load-bearing spine wall running front to back, and it is almost always this wall homeowners want gone to link the kitchen to the rear reception room. Because that wall carries first-floor joists and often part of the roof, every job starts with a structural engineer calculating the load and specifying an RSJ sized to suit the span.
On these generous suburban plots the ground floors are wide, so the beam frequently needs to bear onto padstones set into sound brickwork at each end. We prop the structure temporarily, take the wall down in a controlled, staged sequence, drop the steel into place and pack it tight, so the floor above never moves while we work.
Housing in Bexley
The valuation list shows roughly 101,760 homes in Bexley, of which 11% are pre-1919, 41% interwar and 48% post-1945, split 27% flats to 73% houses. 36% of homes here are semi-detached; only the beam end on the shared wall of a semi in Bexley needs a party wall notice.
What Bexley charges to approve a wall removal, and why the route matters
Bexley Council adjusted its building control fees from 20 April 2026, so a figure on an older estimate for your Bexley wall removal may be out of date. Taking out a single internal wall is likely to be charged as a domestic internal alteration, which Bexley bands by the estimated cost of the work. In the band for internal work of modest estimated cost, the full plans charge and the building notice charge are the same figure, and the regularisation charge is higher. In that band there is no fee saving in skipping the plan check. Bexley shows these prices exclusive of VAT and adds VAT at 20%, except on regularisation charges.
The route changes what happens on the day. With full plans approved, the drawings show the beam, the padstones and the fire protection before anyone lifts a tool, and the quote is fixed against them. With a building notice there is nothing approved to price against, and the inspector's view of the bearings on site settles the final specification. In a Bexley semi where the wall also carries a first floor partition, that difference matters: a larger section decided on the day means the props stay in longer and the plasterer arrives later.
Building control sign-off in DA7 and DA6
Removing an internal load-bearing wall is a Building Regulations matter, not a planning one, so no planning application is needed, even in a conservation area. The exception is a listed house, which needs listed building consent for internal work as well. Bexley Council's building control inspects the beam, its bearings and the padstones, and issues the completion certificate you will want when you come to sell.
Where the wall you are opening abuts the neighbouring property, the shared party wall in a semi means the Party Wall Act can apply, and you serve notice as building owner before starting, using the drawings we supply. We appoint the engineer for the calculations and handle the propping, the steelwork and the making good, so one accountable team sees the job through from survey to signed-off certificate.
Fire protection and finishing the new beam
Steel is strong but it loses strength quickly in a fire, so the Building Regulations require the beam to be protected. In practice that means boarding it in plasterboard, usually two layers or a single fire rated board depending on the specification, before it is skimmed. Encasement is part of the design rather than an afterthought, and it is one reason a finished flush beam sits slightly deeper than the bare steel section suggests.
The finish matters to the room as well. A downstand boarded square reads as a beam. Boxed with a shallow return and a shadow gap, or picked up as a bulkhead across the full width of the room, it reads as part of the ceiling. In a Bexley semi with a through lounge running from the bay to the rear doors, that detail decides whether the space feels like one room or two joined together, so we agree it before the boarding goes on.

FAQ
Frequently Asked Questions about Load-Bearing Wall Removal Bexley
Is a cheap load-bearing wall removal quote in Bexley worth taking?
A cheap load-bearing wall removal quote in Bexley is only worth taking if it covers the same work, and usually it does not. A low figure normally leaves out the approvals (the engineer's calculations and Bexley Council building control sign-off of the beam) or the making good, both of which still get paid for at DA6. GS Renovation itemises within £2,500 to £6,500 or more per opening (indicative) so the comparison is honest.
Do I need planning permission to remove a load-bearing wall in my Bexley semi?
No. Removing an internal load-bearing wall is controlled under the Building Regulations, not planning, so no planning application is required, even in a Bexley conservation area. If the house is listed, listed building consent is needed for the internal work. Bexley Council building control checks the engineer's beam and bearings and certifies the work. We arrange the inspections and the completion certificate as part of the job.
How can I tell whether the wall I want gone in my Bexley house is load-bearing?
Lift a floorboard upstairs and look at which way the joists run. If they cross the wall and rest on it, or another wall stands directly above it, it is carrying load. The front-to-back spine wall in a Bexley interwar semi usually does both. An engineer still confirms it, because a light-looking partition can pick up a roof strut from the loft.
In what order do the approvals go for taking out a wall in Bexley?
The engineer's calculations come first, since everything after them relies on the beam size. Where one end of the steel lands in next door's side of the structure, the neighbour is served formally, with two months minimum before the first cut. The Bexley Council building control application goes in with the calculations attached, and the props go up only once both are settled.
What needs making good in the floor and ceiling after a Bexley wall comes out?
A strip of floor where the wall stood and a scar across the ceiling. Over a suspended timber floor the gap is joisted and boarded; on a concrete slab it is filled and levelled. The ceiling is patched either side of the boxed steel. If the two rooms sat at slightly different heights, agree the new threshold before plastering.
What changes if my Bexley property is a flat rather than a house?
Consent and the load path. Flats are 27% of Bexley's dwellings on the VOA count, and a lease normally requires the freeholder's written consent before a structural wall is touched. The wall may carry the flats above, so the engineer traces the load through the block. Opening a hall into a living room also changes the fire escape route, which building control must agree.
Who has to agree before a load-bearing wall comes out of a Bexley flat?
27% of Bexley homes are flats, and in a flat the wall is rarely yours alone. The lease normally reserves the structure to the freeholder, so written consent from the freeholder comes before drawings are paid for. The floor between two flats is a party structure under the Party Wall Act, so work cutting into it can need notice to the flat above or below, served by you as building owner. Building control approval is needed as well.
What has to reach Bexley building control once the wall work is finished?
A notice of completion. In Bexley it must reach the local authority not more than five days after the building work has been completed. On a wall removal, completion means the steel is encased and the opening made good, not the day the props come out. A late notice can hold up the completion certificate, and that certificate is what a buyer or lender will ask for later. Agree at the start who sends the notice, so it goes in on time.
Is removing a wall different in a Bexley house built after 1945?
It can be. 48% of Bexley homes were built after 1945, and houses of that period can differ from interwar ones: blockwork partitions, precast concrete lintels and, in later houses, trussed rafter roofs that bear only on the outside walls. Under a trussed roof an upstairs wall may carry little from above, while the ground floor wall beneath it can still carry the first floor joists. The structural engineer we appoint checks what the wall supports from above before any beam is sized.
