There are several different deadlines under the Party Wall etc. Act 1996. People often confuse the period before work may begin with the period an adjoining owner has to respond. These are not the same thing.
At a glance
| Work or action | Usual statutory period |
|---|---|
| Existing party structure: section 3 | At least 2 months' notice |
| New wall at the line of junction: section 1 | At least 1 month's notice |
| Qualifying excavation: section 6 | At least 1 month's notice |
| Neighbour response to relevant notices | Generally 14 days from service |
| Validity of a notice | Generally 12 months from service, subject to statutory conditions |
Can you begin before the notice period ends?
The official explanatory booklet explains that an adjoining owner may agree in writing to an earlier start. Such agreement is not automatic. This site's builder uses ordinary minimum notice periods and does not attempt to prepare special early-start agreements.
What does the 14-day rule actually mean?
For work to an existing party structure and qualifying excavation, no written consent within 14 days generally leads to the Act's dispute process. For a wall astride the boundary, the owner needs express written consent: silence is not consent. For a wall wholly on your land, the position is different. Read our guide to neighbours who do not reply rather than assuming the same rule applies to every notice.
When does the clock start?
The key date is valid service, not simply when the document was generated. A dated PDF does not establish that it has reached the person legally entitled to receive notice. Keep evidence of delivery, and consult the official guidance if there is any doubt about service.
Will your notice last indefinitely?
No. Notices are normally subject to a 12-month validity period, with other statutory conditions. Avoid preparing a notice too early, and review it if the intended work or recipient information changes.
