About our flat & HMO conversion steels service in Banstead
For homes in Banstead and the KT17, KT18, KT20 and SM7 districts, we handle flat & HMO conversion steels from survey to sign-off. We also work in nearby Crawley, roughly 14.5 miles away. The beam is sized by a structural engineer and inspected before it is boxed in.
Turning a large house into flats or an HMO rarely leaves every wall where it was. Rooms are split and joined, kitchens and bathrooms appear on upper floors, and new stairs or corridors are formed. Each time a load-bearing wall moves, steel usually takes its place, and it has to suit the fire and sound standards of a building shared by several households.
What to expect
- The reduced 5% rate of VAT may apply to some conversion work, such as changing the number of dwellings in a building. Whether it applies depends on the details of the scheme, so confirm the position with your accountant before relying on it.
- Where the building is leasehold, or an existing flat is being altered, the freeholder's written consent is normally needed for structural changes. Lenders may also want to see building control sign-off before releasing funds on a converted property.
- Keep the structural calculations, building control completion certificate and fire protection records together in one place. They are needed for signing off the conversion, and buyers, lenders and licensing officers may ask to see them later.
- The engineer looks at the whole building rather than one opening at a time. Loads from upper floors, new bathrooms and water storage are traced down to the foundations, and steel is placed so it suits the new layout without awkward downstands in habitable rooms.
- Conversions add kitchens and bathrooms upstairs, so soil pipes, water supplies and extract ducts need routes through the structure. Steel and joist positions are coordinated with these runs, and steel should never be drilled or notched on site without the engineer's approval.
How the job runs in Banstead
Free visit
A short visit to Banstead to see the job, agree what you want and check the bearings, floors and services that affect the design.
Calculations
The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.
Building control
We submit a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
Steel in, made good
On site we prop, open up, fit and pack the steel, then fire protect, box in and plaster once the inspection is done.

Building control and neighbours in Banstead
For Banstead, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
If the beam bears into a wall you share with a neighbour, the Party Wall etc. Act 1996 applies, and a party structure notice must be served at least two months before that work starts. We arrange this through a party wall surveyor.

Flat & HMO conversion steels in Banstead: your questions
Can you work on older or listed homes in Banstead?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Do I need a party wall agreement for flat & HMO conversion steels in Banstead?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
Do I need building regulations to convert a house into flats?
Yes. Converting a house into flats is a material change of use, so the building has to meet requirements for fire safety, sound insulation, structure and other matters. In England and Wales that means a building control application, in Scotland a building warrant before work starts, and in Northern Ireland an application to council building control.
Do I need planning permission to convert a house into an HMO?
You may, depending on the size of the HMO, where it is and any local restrictions. In some areas smaller HMOs can be formed without a planning application, while larger ones, and conversions into self-contained flats, usually need permission. Check with the local planning authority before committing to a layout and its steelwork.
What steel beams are needed for a flat conversion?
It depends on how much the layout changes. Typical steelwork includes beams where load-bearing walls are removed, trimmers around new stair openings, and columns or frames where loads have to come down through the building. A structural engineer designs each element from the new layout and the existing structure, and the calculations go to building control.
How much do flat & HMO conversion steels cost in Banstead?
As a guide, budget £2,800–£10,100 including VAT for steelwork for a flat or HMO conversion in Banstead, based on published UK cost guides adjusted for prices in the South East (+12%). The exact figure depends on the span, what the wall carries, access and the finish, and is fixed in writing once the scope is agreed.
