What flat & HMO conversion steels involve in Leigh
We carry out flat & HMO conversion steels in Leigh, covering the M29, M46 and WN7 postcode districts. It sits about 5.8 miles from Wigan, which we also cover. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We supply and install steelwork for landlords, developers and their builders, working from the engineer's design and fitting in with the wider conversion. We arrange structural calculations, handle building control for the structural work or feed into your existing application, and fire protect the steel to the period the scheme requires.
What to expect
- 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.
- In a conversion, walls that carried load are often taken out to form open kitchens or wider corridors, while new partitions go in elsewhere. Each change is checked, because a new stud wall standing on old joists can add load the floor was never designed for.
- Large Victorian and Edwardian houses are popular for conversion, but they bring timber lintels, chimney breasts, lime mortar and joists notched for old services. These are uncovered early so the engineer can account for them before any steel is ordered.
- Many HMOs need a licence from the local council, with conditions covering room sizes, shared facilities and fire safety. Licensing runs alongside building regulations rather than replacing them, so the layout and steelwork should suit both from the outset.
- 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.
What happens, step by step
Survey in Leigh
We visit, look at the wall and what sits above it, measure the opening and note services, access and how the steel can be brought in.
Engineer's design
A structural engineer sizes the beam, padstones and any posts, and sets out the temporary support needed while the wall is out.
Building control
We submit a building notice or full plans application to Wigan Council, so approval is in place before the wall is touched.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building control inspects it, and we make good.

Approvals in Leigh
For Leigh, building control is provided by Wigan Council, 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.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.

Local questions answered
Who approves flat & HMO conversion steels in Leigh?
Structural work in Leigh needs a building notice or full plans application to Wigan Council or a registered building control approver. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
Do I need a party wall agreement for flat & HMO conversion steels in Leigh?
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.
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.
Does steel in a flat conversion need fire protection?
Yes, in almost all cases. Steel holding up floors that separate flats, or supporting escape routes, needs fire resistance to the period the scheme requires, which can be higher than in a single house. It is usually boxed with fire-rated board or coated with intumescent paint, and building control inspects it before handover.
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.
