What a party wall notice involves

A party wall notice is a formal written notice that you must give your neighbours under the Party Wall etc. For a two-storey extension it usually covers building a new wall on the boundary, cutting beams into a shared wall or digging foundations near a neighbour's.

Across Powys we cover Newtown (SY16), Brecon (LD3), Welshpool (SY15), Llandrindod Wells (LD1), Knighton (LD7) and Llanidloes (SY17), plus the smaller places around them.

Fees

We confirm every fee in writing before the design stage starts; typical professional fees are on our prices page.

Rules in Wales

In Wales, the Party Wall etc. Act 1996 applies in the same way as in England. Notices are needed for a new wall on the line of junction, work to a party wall and excavation near a neighbour's foundations, with the same 1 month and 2 month periods. One agreed surveyor typically costs £1,300–£1,500 plus VAT.

Approval in Wales: Householder planning application: £585. Councils normally decide householder applications within 8 weeks.

Building regulations: Building regulations approval under the Welsh Approved Documents, which differ from England's in places (notably energy efficiency).

Getting the design right

Talking to neighbours first

A conversation before the notice arrives often makes the difference between consent and dissent. We explain the work, share the drawings and answer questions, so neighbours know what to expect and are more likely to agree.

Building the timing in

Notice periods add to the programme, and a dissent can add more while surveyors agree the terms. We serve notices once the design and foundations are known, usually while planning is being decided, so they run in parallel with other approvals.

How we work in Powys

  1. Look at the house

    We start in Powys with a free visit: measurements, photos, a look at the loft and drains, and a frank chat about budget.

  2. Drawings and permission

    Our designers produce plans and elevations, then we take care of planning or permitted development checks with the council covering Powys.

  3. Detail and price

    Construction drawings, engineer's calculations and building control sign-off, then a written fixed price for the build.

  4. Build

    Foundations, walls, floor, roof, windows, then first and second fix. We break through into the house as late as we can.

Party wall notices for extensions in Powys: questions

What happens if my neighbour does not respond to a party wall notice?

For a party structure notice or an excavation notice, a neighbour who does not respond within 14 days is treated as having dissented. Surveyors are then appointed to agree a party wall award, which sets out how the work will be done and records the condition of the neighbour's property. Either one agreed surveyor or one for each side can act.

Can my neighbour stop my extension with the Party Wall Act?

No. The Party Wall etc. Act 1996 sets out how work is done and how neighbours are protected, but it does not let them block lawful work that has planning approval or is permitted development. It can delay the start if notices are served late, which is why we serve them early.
