About our party wall beam works service in Hanworth
Our party wall beam works service in Hanworth covers everything from the first visit to the completion paperwork. Our coverage runs across London, so nearby villages are included too. Postcode districts we cover here include TW1, TW2, TW3, TW4 and TW11.
In terraced and semi-detached homes, the most obvious place for a new beam to bear is often the wall you share with next door. That wall belongs partly to your neighbour, so in England and Wales the law sets out a process for telling them, recording the condition of their side and settling any disagreement before the steel goes in.
Worth knowing before you start
- 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.
- 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.
- 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.
- 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.
What happens, step by step
Survey in Hanworth
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 a building notice or full plans application to the local council's building control team, so approval is in place before the wall is touched.
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.

Approvals in Hanworth
For Hanworth, building control is provided by the local council's building control team, or by a registered building control approver if preferred. We send them the engineer's calculations with a building notice or full plans application and book the inspections. Work done without approval can cause problems at sale and is far dearer to put right later.
Terraced and semi-detached homes often need party wall notices, because cutting into a shared wall to take a beam end is notifiable under the Party Wall etc. Act 1996. Allow at least two months for the notice period unless your neighbour agrees sooner.
Party wall beam works in Hanworth: your questions
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.
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.
Do I need a party wall agreement to put a steel beam in?
Yes, in England and Wales, if the beam will bear into a wall you share with a neighbour. Notice is required under the Party Wall etc. Act 1996, and the neighbour may consent in writing or dissent, in which case surveyors produce a party wall award. Scotland and Northern Ireland have no equivalent Act.
