Building rules in Carmarthenshire
Welsh building regulations treat beams and new openings as controlled building work. We apply to Carmarthenshire 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.

Steel beams in Carmarthenshire: questions
Who approves steel beam installation in Carmarthenshire?
Structural work in Carmarthenshire needs a building control application to Carmarthenshire County Council under the Welsh regulations, with a commencement notice 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.
How soon can steel beam installation start in Carmarthenshire?
Start dates depend on the engineer's calculations, the building control approval and, where needed, party wall notice periods. We give you a realistic timetable after the survey and keep you updated as each approval comes through.
Can you work on older or listed homes in Carmarthenshire?
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 Carmarthenshire for steel beam installation?
