What Happens if a Neighbour Signs a Party Wall Notice But Then Objects?
Consent given in writing on a valid notice generally allows the described work to go ahead. Whether it can be withdrawn afterwards is not clearly settled, so get professional advice quickly and stop to talk before either side escalates.

- Find the signed notice and check exactly what work it describes.
- Ask the neighbour, in writing, what they now object to.
- Check whether the objection concerns the described work or something different.
- Do not start, or pause, work until you have advice.
- Speak to a party wall surveyor about your position.
- Consider inviting the neighbour to appoint a surveyor to address their concerns.
What consent actually does
An adjoining owner can consent to a notice. Consent applies to the work described, on the terms of the notice. It is not possible to consent where the process needs a surveyor's involvement, such as after a counter-notice.
Consent does not remove the neighbour's right to a surveyor. They could have dissented instead, which would have led to an award.
Can consent be withdrawn?
The Act does not clearly deal with this. Whether a neighbour can change their mind after consenting, and at what point, is uncertain. Do not assume either way.
If work has not started, the practical route is often to serve a fresh notice or to treat the objection as opening a dispute and appoint surveyors. If work has started, take advice at once.
When the work changes
If the scope of work grows beyond what the notice described, the old consent does not cover it. A new notice would normally be needed.
A neighbour who objects because the plans have changed has a fair point. Check the drawings against the original notice.
Reaching a sensible outcome
Many objections are worries about damage or noise. Offering a schedule of condition and a surveyor to answer questions often settles them. An award then gives both sides a written structure.
Frequently asked questions
Is consent legally binding?
For the work described in a valid notice, it generally allows the work. Whether it can be withdrawn is uncertain.
Can the neighbour demand a surveyor after consenting?
That is not clear cut. Take advice, as the safe route is often to bring surveyors in.
What if I already started work?
Pause and get advice. Continuing may raise the risk of an injunction.
Do I need a new notice?
If the work has changed from the notice, yes, generally.
