Loft conversion steels in Leigh: how it works
We carry out loft conversion steels in Leigh, covering the M29, M46 and WN7 postcode districts. Leigh is around 5.8 miles from Wigan, and we cover both. The job starts with a free survey visit so the engineer's calculations are based on your actual walls, floors and loads.
The joists in most lofts were only ever meant to hold up a plaster ceiling, and the roof is often propped on struts and purlins that get in the way of a room. Steel beams solve both problems: they carry a new floor across the house and take over the roof support so the struts can come out.
Things to plan for
- 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.
- Headroom in the finished loft depends partly on where the floor steels sit. Setting them low, between the existing ceiling joists, keeps more height upstairs, and the engineer and loft designer agree the levels together.
- Ceiling joists in most houses are too shallow to carry people, furniture and a bathroom. Rather than loading them, steel beams span between the walls and new, deeper floor joists hang from them, sitting just above the old ceiling.
- 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.
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.
What do loft conversion steels cost in Leigh?
As a guide, budget £2,400–£5,750 including VAT for loft conversion steels in Leigh, based on published UK cost guides adjusted for prices in the North West (-4%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Loft conversion steels | £2,400–£5,750 | Supply and fit of floor and ridge steels on padstones, including lifting into the roof space |
| RSJ supply and fit (single beam) | £770–£2,400 per beam | Beam supplied, delivered, lifted and packed on padstones, with propping (calculations and approval priced separately) |
| Party wall surveyor (agreed surveyor, per neighbour) | £860–£1,920 per neighbour | Schedule of condition and award where a neighbour dissents; serving notice alone, where the neighbour consents, costs far less (England and Wales only) |
| Fire protection to a steel beam | £140–£580 per beam | Fire-rated board boxing or an intumescent coating system as specified |
Figures include our approximate regional adjustment for prices in the North West (-4%) and are rounded. How these figures are worked out.
Building control and neighbours in Leigh
Structural openings in English homes need building regulations approval before work starts. Wigan Council 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.

Loft conversion steels in Leigh: your questions
Can you work on older or listed homes in Leigh?
Yes. Older homes often have lime mortar, timber lintels or shallow footings, which the engineer allows for. Listed buildings need listed building consent for internal structural changes as well as building regulations approval, and that must be in place first.
Do you cover Leigh for loft conversion steels?
Yes. We carry out loft conversion steels in Leigh and the M29, M46 and WN7 postcode districts. Book a free survey visit and we will check the wall, arrange the engineer's calculations and send an itemised written quote.
Do I need building regulations for loft conversion steels?
Yes. Loft conversions are building work, and the steels form part of the structural design checked by building control in England, Wales and Northern Ireland. In Scotland a building warrant must be granted before work begins. The inspector checks the steel bearings before they are covered up.
Can my loft be converted if it has trussed rafters?
Often it can, but it is a bigger structural job. Trussed rafters have diagonal webs right through the loft, and every truss that is cut needs its load picked up by new steel and timber. The engineer designs that, and the roof is propped carefully throughout.
Do all loft conversions need steel beams?
Most do, but not all. Steels are usually needed to carry the new floor, replace purlins and struts, or support the roof around a dormer. Some smaller conversions use deeper timber joists or engineered timber instead. A structural engineer decides what the roof and walls need after a survey.
How much do loft conversion steels cost in Leigh?
As a guide, budget £2,400–£5,750 including VAT for loft conversion steels in Leigh, based on published UK cost guides adjusted for prices in the North West (-4%). 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.
