Planning flat & HMO conversion steels in the Scottish Borders
Flat and HMO conversion steels are the beams, columns and frames needed when a house or building is reworked into self-contained flats or a house in multiple occupation. New layouts move walls, stairs and bathrooms, so steel picks up the loads that old walls used to carry, designed to work alongside the fire separation and sound insulation the conversion also needs.
Looking for flat & HMO conversion steels in the Scottish Borders? We work in Galashiels, Kelso and Selkirk and the surrounding villages. Our teams handle the calculations, the building warrant, the propping and the steel itself, and leave the opening ready for plastering and decoration.
Worth knowing before you start
- Keep the structural calculations, building standards 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.
- 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.
- 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.
- 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.
- 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.
From survey to sign-off in the Scottish Borders
Free visit
A short visit to the Scottish Borders 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 warrant
A building warrant is applied for from Scottish Borders Council, and work starts only once the warrant has been granted.
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 the Scottish Borders
In Scotland, structural alterations need a building warrant under the Building (Scotland) Act 2003, and work must not start until the warrant is granted. For the Scottish Borders, warrants are handled by Scottish Borders Council's building standards service. When the work is finished, a completion certificate is submitted and has to be accepted by the council.
There is no party wall notice system in Scotland. Instead, check your title deeds and, for flats, the tenement management scheme, and talk to neighbours early if the beam bears into a shared wall.
Local questions answered
Do I need a party wall agreement for flat & HMO conversion steels in the Scottish Borders?
There is no Party Wall Act in Scotland. Your title deeds and the general law apply instead, and the Tenements (Scotland) Act 2004 for flats, so agree the work with your neighbour in writing before it starts.
Can I stay at home while the work is done in the Scottish Borders?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
How long does the steelwork take on a house-to-flats conversion?
Typically one to three weeks on site, depending on how many walls move and how the work is phased. The steel is usually among the first structural stages, so it is programmed early to let partitions, services and fire separation follow. The full conversion takes considerably longer than the steelwork alone.
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 standards inspections for the steel so the other trades can follow on smoothly once it is in.
Do I need an HMO licence before converting a house?
Possibly. Many HMOs need a licence from the local council, and some areas license smaller HMOs too. Licensing covers room sizes, amenities and fire safety, and it is separate from planning and building regulations. Check the council's requirements early, as they can affect the layout and therefore the steelwork needed.
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 standards inspects it before handover.
Which towns in the Scottish Borders do you cover?
We cover towns including Hawick, Galashiels, Peebles and Kelso, plus the villages and smaller towns around them.
