Planning party wall beam works in Caerphilly
Looking for party wall beam works in Caerphilly? We work in Gelligaer, Blackwood and Risca and the surrounding villages. Our teams handle the calculations, the building control approval, the propping and the steel itself, and leave the opening ready for plastering and decoration.
What to expect
- 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.
- A schedule of condition records the neighbour's side of the wall before work begins, usually with written notes and photographs of existing cracks and finishes. It gives both sides a fair reference point if anyone later claims the work caused damage.
- Cutting a pocket into a shared wall needs care, because the wall also supports the neighbour's floors and roof. The engineer specifies how the pocket is formed and packed, and props or needles may be needed to keep both houses supported while it is cut.
- Cutting into a party wall is noisy on both sides and can disturb loose plaster or pictures next door. Telling the neighbour the dates in advance, protecting their side where access is agreed, and keeping to agreed hours all help the work go smoothly.
- An adjoining owner can consent in writing, dissent, or serve a counter-notice asking for extra works to suit them. Silence after the response period is treated as a dissent, which simply means surveyors are appointed to agree how the work proceeds.
How the job runs in Caerphilly
Survey in Caerphilly
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 Caerphilly County Borough 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.

Building control and neighbours in Caerphilly
Welsh building regulations treat beams and new openings as controlled building work. We apply to Caerphilly County Borough 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.
Local questions answered
What happens at the survey visit in Caerphilly?
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.
Which towns in Caerphilly do you cover?
We cover towns including Risca, Gelligaer and Blackwood, plus the villages and smaller towns around them.
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.
What is a schedule of condition?
A schedule of condition is a written and photographic record of the neighbour's property, focused on the rooms next to the party wall, made before work starts. It notes existing cracks, stains and finishes. If damage is alleged later, the surveyors compare the property with the schedule to see what changed during the work.
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.
How much notice do I need to give my neighbour?
At least two months for a party structure notice, which is the notice needed for cutting into a party wall to take a beam. The neighbour can agree in writing to an earlier start, but that cannot be assumed. Building the notice period into the programme early stops it delaying the rest of the job.
