About our loft conversion steels service in Haverfordwest
Haverfordwest has a mix of housing, and loft conversion steels need a slightly different approach in each. We also cover the surrounding towns and villages in Pembrokeshire. Whatever the age of the property, the steel goes in on proper bearings with temporary support in place throughout.
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 control, getting long steels into a roof space safely, bedding them on padstones and packing them before the new floor and dormer go on.
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.
- 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.
- 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.
- Loft steels usually bear on the gable wall in a semi-detached house or on the party wall in a terrace. The engineer checks that the wall below can take the point load and specifies padstones to spread it, sometimes with a steel post down to lower floors.
- 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.
From survey to sign-off in Haverfordwest
Free visit
A short visit to Haverfordwest 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 Pembrokeshire 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.

Approvals in Haverfordwest
Welsh building regulations treat beams and new openings as controlled building work. We apply to Pembrokeshire 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.

Loft conversion steels in Haverfordwest: your questions
Can you work on older or listed homes in Haverfordwest?
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 I need a party wall agreement for loft conversion steels in Haverfordwest?
Yes, if the beam bears into a shared wall: the Party Wall etc. Act 1996 applies in England and Wales, and a party structure notice must be served at least two months before that work starts. We arrange it through a party wall surveyor.
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.
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.
