About our flat & HMO conversion steels service in Maesteg

We carry out flat & HMO conversion steels in Maesteg, covering the CF34 postcode district. Our coverage runs across Bridgend, so nearby villages are included too. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.

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.

Worth knowing before you start

  • Costs reflect how many walls move, the number of beams and columns, access for lifting steel to upper floors, the fire period required, phasing around other trades and whether existing foundations can take the new concentrated loads.
  • 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.
  • 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.
  • Separating floors and walls also have to meet sound insulation standards. Steel connections and boxing are detailed so they do not leave gaps or rigid paths for noise, and sound testing near completion checks that the separating construction performs.

From survey to sign-off in Maesteg

  1. Free visit

    A short visit to Maesteg to see the job, agree what you want and check the bearings, floors and services that affect the design.

  2. Calculations

    The engineer's calculations and a simple drawing are prepared for your opening and shared with you before anything is ordered.

  3. Building control

    We submit the application or notice to Bridgend County Borough Council under the Building Regulations as they apply in Wales, before work starts.

  4. 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 rules for Maesteg

Welsh building regulations treat beams and new openings as controlled building work. We apply to Bridgend County Borough Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.

Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Flat & HMO conversion steels in Maesteg: your questions

How much do flat & HMO conversion steels cost in Maesteg?

As a guide, budget £2,300–£8,200 including VAT for steelwork for a flat or HMO conversion in Maesteg, based on published UK cost guides adjusted for prices in Wales (-9%). 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.

How soon can flat & HMO conversion steels start in Maesteg?

Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.

Can you install the steel while my main contractor runs the conversion?

Yes. On many conversions the steelwork is installed as a package within a wider build, working to the main contractor's programme and the engineer's design. We coordinate propping, deliveries and building control inspections for the steel so the other trades can follow on smoothly once it is in.

Does 5% VAT apply to a flat conversion?

It may. A reduced rate of VAT can apply to some conversion work, such as changing the number of dwellings in a building or converting a house into an HMO, provided the conditions are met. The rules have detail and exceptions, so confirm the position with your accountant before pricing the project on that basis.

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.
