Planning loft conversion steels in Holyhead
If you live in Holyhead, loft conversion steels can usually be planned and priced after a single survey visit. We also cover the surrounding towns and villages in Anglesey. We cover LL65, and we fix the price in writing once the layout and scope are agreed.
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.
Key points for your project
- 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.
- 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.
- 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.
- 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.
- The steel stage of a loft conversion usually takes a few working days and comes early, before floor joists, dormer framing and insulation. Keep the steel calculations with the completion certificate, as both are asked for when the house is sold.
Four stages, one team
Free visit
A short visit to Holyhead 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 control
We submit the application or notice to Isle of Anglesey County Council under the Building Regulations as they apply in Wales, before work starts.
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.

| Steel column or post | £460–£1,360 per column | Column supplied and fitted with base and cap plates on a pad foundation |
| Fire protection to a steel beam | £140–£550 per beam | Fire-rated board boxing or an intumescent coating system as specified |
| 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 Wales (-9%) and are rounded. How these figures are worked out.
Building rules for Holyhead
Welsh building regulations treat beams and new openings as controlled building work. We apply to Isle of Anglesey County Council on your behalf before anything is removed, give the commencement notice the 2026 Welsh rules require, and the steel is checked before it is boxed in.
The Party Wall etc. Act 1996 applies in Wales as well as England, so a beam bearing into a shared wall needs a party structure notice at least two months before work starts. We arrange notices through a party wall surveyor.

Questions about loft conversion steels in Holyhead
What happens at the survey visit in Holyhead?
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.
How much do loft conversion steels cost in Holyhead?
As a guide, budget £2,300–£5,450 including VAT for loft conversion steels in Holyhead, based on published UK cost guides adjusted for prices in Wales (-9%). 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.
How do you get steel beams into a loft?
It depends on access. Beams are often passed in through an opening made in the roof or a gable window, or brought up in shorter sections and bolted together in the loft where the engineer's design allows. For long or heavy steels a hoist or crane may be used, planned in advance.
Where do loft conversion steels sit?
Usually between the gable walls or party walls, bearing on padstones bedded into pockets cut in the brickwork. Floor beams sit low, close to the existing ceiling, while ridge or dormer beams sit higher up to support the roof. The engineer sets the exact positions and levels.
Do loft conversion steels need fire protection?
Usually, yes. Steel loses strength in a fire, and the beams carrying the new floor are elements of structure. In a typical house they commonly need 30-minute fire resistance, often provided by fire-rated plasterboard around and below the steel, as agreed with building control.
Do you also work near Holyhead?
Yes. We also cover nearby towns including Llangefni, Amlwch, Caernarfon and Menai Bridge.
