Party wall beam works in Anglesey: how it works
Across Anglesey, party wall beam works usually come up when people want more light, a better layout or a way through to a new extension. Coverage takes in Menai Bridge, Amlwch and Holyhead and everywhere in between. Whatever the reason, the beam is sized from calculations and the work is inspected before anything is covered.
Things to plan for
- 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.
- Keep the notices, any written consent, the schedule of condition and the award with your building control certificate. A buyer's solicitor may ask whether party wall procedures were followed, and these documents answer that. For legal questions, a solicitor or the surveyor is the right adviser.
- 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.
- 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.
- A party wall is usually the wall dividing two attached homes, such as the wall between terraced or semi-detached houses. Garden walls straddling the boundary are party fence walls, but for beam work it is the main separating wall between the houses that usually matters.
What happens, step by step
Free visit
A short visit to Anglesey 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 Isle of Anglesey 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.
How much should I budget in Anglesey?
As a guide, budget £820–£1,820 per neighbour including VAT for party wall surveyor (agreed surveyor, per neighbour) in Anglesey, based on published UK cost guides adjusted for prices in Wales (-9%).
| Job | Typical guide range | What it usually covers |
|---|---|---|
| Party wall surveyor (agreed surveyor, per neighbour) | £820–£1,820 per neighbour | Schedule of condition and award where a neighbour dissents; serving notice alone, where the neighbour consents, costs far less (England and Wales only) |
| Structural calculations for a beam | £230–£680 | Site measure or photos, beam and padstone design and calculations for building control |
| Building control fees | £230–£590 | Application fee and inspections under the Welsh building regulations; varies by council or approver |
| Side return extension steelwork | £3,200–£7,750 | Beams and posts along the old side wall line, propping and approvals (extension build extra) |
Figures include our approximate regional adjustment for prices in Wales (-9%) and are rounded. How these figures are worked out.
Approvals in Anglesey
In Wales, structural alterations come under the Building Regulations 2010 as they apply in Wales. Isle of Anglesey County Council handles building control for Anglesey. 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.

Questions about party wall beam works in Anglesey
Can I stay at home while the work is done in Anglesey?
Usually, yes. The work area is screened and floors are protected. The rooms either side of the opening are out of action for a few days, and there is some noise and dust while the masonry comes out.
What happens at the survey visit in Anglesey?
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.
What if work starts without serving a party wall notice?
The neighbour can seek a court injunction to stop the work until the proper procedure is followed, and starting without notice weakens the building owner's position if damage is later disputed. It can also cause problems when either property is sold. We do not start notifiable party wall work until the notice process is complete.
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.
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.
