Planning loft conversion steels in Bonnyrigg
We carry out loft conversion steels in Bonnyrigg, covering the EH18, EH19, EH20, EH22 and EH23 postcode districts. We also cover the surrounding towns and villages in Midlothian. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
We fit the steel package for loft conversions, either as part of the full project or alongside your loft builder. That means the engineer's design, building standards, getting long steels into a roof space safely, bedding them on padstones and packing them before the new floor and dormer go on.
Things to plan for
- A rear dormer removes part of the roof slope, so the rafters above lose their support at the lower end. A ridge beam or a beam along the dormer's front edge carries them instead, designed for the dormer width and the weight of the roof.
- Traditional cut roofs rely on purlins and struts running down to internal walls. A steel beam can take over that job so the struts come out, freeing up floor and headroom, but the change has to be designed and propped carefully.
- Getting steel into a loft is often the hardest part of the job. Beams can be brought through a roof opening, a gable window, or in shorter lengths bolted together inside, provided the engineer's design allows for the splice.
- Many later twentieth-century homes have trussed rafter roofs, with diagonal timbers running through the whole loft. Converting these involves more steel and new timber, because each truss is cut and its load has to be re-routed by design.
- Water tanks, cables, aerial leads and bathroom extract ducts often sit exactly where the steel needs to go. They are moved before the beams arrive, and old cold water tanks are frequently removed as part of the wider loft project.
How the job runs in Bonnyrigg
Survey in Bonnyrigg
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 warrant
A building warrant is applied for from Midlothian Council, and work starts only once the warrant has been granted.
Install and sign-off
Props go in, the opening is formed, the steel is set and packed, building standards inspects it, and we make good.

| Job | Typical guide range | What it usually covers |
|---|---|---|

| Steel column or post | £460–£1,360 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| RSJ supply and fit (single beam) | £730–£2,280 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
Figures include our approximate regional adjustment for prices in Scotland (-9%) and are rounded. How these figures are worked out.
Approvals in Bonnyrigg
Scottish rules are stricter on timing than in England: the building warrant must be in place before the wall is touched. We prepare the application with the engineer's calculations and submit it to Midlothian Council. The finished work is then certified and a completion certificate submitted for acceptance.
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.

Questions about loft conversion steels in Bonnyrigg
Do you also work near Bonnyrigg?
Yes. We also cover nearby towns including Musselburgh, Penicuik, Tranent and Haddington.
Do I need a party wall agreement for loft conversion steels in Bonnyrigg?
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 in my house during a loft conversion?
Usually, yes. Most of the steel work happens in the roof space, with access through the loft hatch or a roof opening, so the rest of the house stays usable. Expect noise while pockets are cut into the walls and some dust on the landing, which is screened off.
How long does it take to install loft steels?
The main steels for a typical loft conversion usually go in over two to five working days. That covers cutting pockets, bedding padstones, getting the steel in and packing it. The timing depends heavily on access and how many beams the design calls for.
What is a ridge beam in a loft conversion?
A ridge beam is a steel beam running along the top of the roof to support the rafters when their usual support is removed, such as when a large dormer is built or a hipped roof is converted to a gable. The engineer decides whether one is needed and specifies it.
Who approves loft conversion steels in Bonnyrigg?
Structural work in Bonnyrigg needs a building warrant from Midlothian Council, granted before work starts. We prepare and submit it with the structural engineer's calculations and arrange the inspections, so the completion paperwork follows the job.
