About our party wall beam works service in Carmarthenshire
Across Carmarthenshire, party wall beam works usually come up when people want more light, a better layout or a way through to a new extension. That includes Ammanford, Llanelli and Carmarthen, plus smaller towns and villages nearby. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
What to expect
- A party structure notice must be served at least two months before the work starts. That lead time is easy to overlook, so we build it into the programme from the first visit rather than discovering it when the steel is ready.
- If there is a dissent, the owners can appoint one agreed surveyor to act impartially for both, or a surveyor each. Either way, the surveyors' role under the Act is to resolve the dispute fairly, not to act as advocates for one side.
- Party walls in older terraces are often solid brick with lime mortar, and may carry both houses' chimney flues. The engineer checks the wall's condition and thickness where the beam will bear, and the bearing position may be adjusted to avoid flues still in use.
- Cutting into a party wall to take the bearing of a beam is notifiable work under the Party Wall etc. Act 1996. So is cutting away projections attached to the wall, such as chimney breasts, which often comes up during knock-throughs.
- The party wall award is the document the surveyors produce to settle the dispute. It sets out the work allowed, working hours and methods, access arrangements and how any damage will be dealt with, and both owners are bound by it unless it is appealed.
From survey to sign-off in Carmarthenshire
Survey in Carmarthenshire
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 the application or notice to Carmarthenshire County Council under the Building Regulations as they apply in Wales, before work starts.
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.

Figures include our approximate regional adjustment for prices in Wales (-9%) and are rounded. How these figures are worked out.
Approvals 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.
Where the steel bears into a wall shared with next door, notice must be served under the Party Wall etc. Act 1996. If your neighbour dissents, surveyors agree how the work is done before it starts.

Local questions answered
Can my neighbour stop me putting a beam in the party wall?
Generally no. The Party Wall etc. Act 1996 gives the building owner the right to carry out notifiable work, such as cutting in a beam bearing, provided the proper procedure is followed. A neighbour can dissent, which leads to surveyors setting conditions in an award, but this regulates the work rather than preventing it. Take legal advice on specific disputes.
Can you serve party wall notices for me?
Yes, we arrange notices through a party wall surveyor as part of the job where they are needed. The surveyor prepares and serves the correct notice with the drawings, handles the neighbour's response and, if needed, takes part in the process that leads to an award. We coordinate the timing with the build but do not give legal advice ourselves.
What happens if my neighbour dissents?
A dissent means surveyors are appointed to settle how the work goes ahead; it does not mean the work is refused. The owners either agree on one surveyor or appoint one each. The surveyors usually prepare a schedule of condition of the neighbour's property and publish an award setting out how and when the beam can be fitted.
Who pays for the party wall surveyor?
Normally the building owner, meaning the person having the work done, pays the reasonable fees of the surveyors for both sides, because the work is for their benefit. Fees vary with the number of neighbours affected and the complexity of the work, which is why they sit as a separate item in our quote.
