My neighbour is building but hasn't informed me about any work taking place. What can I do?

Your neighbour should have served notices under the statutory framework. If they haven’t, write pointing out their statutory obligations. If they don’t respond, either party may appoint a surveyor. The surveyor will contact them formally.Your surveyor can insist on a survey. This protects adjoining properties. Don’t wait until damage occurs. Early intervention helps avoid disputes.

I have just found out that I need to serve notice on an adjoining owner but my construction has already started – should I stop?

Yes. Stop immediately and serve proper notices.
Proceeding without compliance exposes you to:
Injunctions
Liability for damage
Legal costs
Builders sometimes don’t understand what work is covered by the Act. Appoint a surveyor immediately. This brings things into compliance.

When does the Party Wall Act apply?

The Party Wall Act applies when:

Building on boundary lines

Doing work that affects a party wall

Excavating within three or six metres of neighbouring foundations

Common projects covered by the Act include:

Loft conversions in terraced and semi-detached properties

Extensions

Basement excavations

Removing chimney breasts

Underpinning

Planning permission is separate from statutory obligations. You can have planning approval and still need a party wall survey.

Is there anything I can do about the construction noise coming from next door?

Party wall agreements can include working hours restrictions. But they don’t override rights to do reasonable work at reasonable times.

Normal hours are acceptable:

8am–6pm weekdays
8am–1pm Saturdays

For excessive noise, contact your local council’s environmental health department. Noise control isn’t covered by the Act.
