Flat & HMO conversion steels in Uxbridge: how it works

For homes in Uxbridge and the UB7, UB8, UB10 and UB11 districts, we handle flat & HMO conversion steels from survey to sign-off. The wider London area is covered as well. The beam is sized by a structural engineer and inspected before it is boxed in.

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

  • 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.
  • 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.
  • A conversion to flats or an HMO may need planning permission for the change of use, depending on the scheme, its size and any local restrictions. Checking the planning position before design work begins avoids redesigning the layout and its steel later.
  • 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.

Four stages, one team

  1. Free visit

    A short visit to Uxbridge 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 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.

  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.

Approvals in Uxbridge

Structural openings in English homes need building regulations approval before work starts. The local council's building control team can deal with it, or you can use a registered building control approver. Either way the steel is inspected before it is covered, and a completion certificate is issued at the end. Keep it safe for when you sell.

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 Uxbridge: your questions

Do you cover Uxbridge for flat & HMO conversion steels?

Yes. We carry out flat & HMO conversion steels in Uxbridge and the UB7, UB8, UB10 and UB11 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.

What happens at the survey visit in Uxbridge?

We look at the wall, the floor and ceiling either side and what sits above, measure the opening you want, and note cables, pipes and access for the steel. It usually takes under an hour and there is no charge.

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.

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.

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

As a guide, budget £3,200–£11,500 including VAT for steelwork for a flat or HMO conversion in Uxbridge, based on published UK cost guides adjusted for London prices (+28%). 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.
