Steel beam work in Holyhead

We install steel beams and RSJs in Holyhead, covering LL65. Our coverage runs across Anglesey, so nearby villages are included too. Common jobs here are knock-throughs, load-bearing wall removal, chimney breasts and openings into new extensions.

In Holyhead, beam work is approved under the Building Regulations as they apply in Wales, and the Party Wall etc. Act 1996 applies to shared walls.

Four stages, one team

  1. Survey in Holyhead

    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.

  2. 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.

  3. 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.

  4. 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.

Building rules in Holyhead

In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Isle of Anglesey County Council handles building control for Holyhead. For work started or approved from 1 July 2026, the Welsh system uses an application to building control, dutyholders appointed in writing, a commencement notice before work starts and a compliance statement at the end.

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.
