Notices Under The Party Wall Act – What Are They, What Should They Contain?

Updated: Mar 20

In our previous article, we briefly outlined the purpose of the Party Wall etc. Act 1996 (the Act) and the legal obligation it places on property owners wishing to carry out certain works that the Act deems to be ‘notifiable’. These notifiable works are considered to carry some risk to the premises of Adjoining Owners and the Act gives these owners the right to influence how this work is carried out.


Types of Notices & Notice Periods

For the process to be started, for the Act to be invoked, a notice has to be served by the Building Owner before the works are due to commence. In general, there are three types of notice that are routinely served in a domestic setting. These are;


  • Line of Junction Notice (Section 1) – where the Building Owner proposes to construct a new wall on, or astride, the ‘line of junction’ (boundary).

  • Party Structure Notice (Section 3) – where the Building Owner proposes to demolish, repair, expose, or otherwise alter a Party Wall or shared Party Structure.

  • Excavation Notice (Section 6) – where the Building Owner proposes to excavate within 3 or 6 metres of a structure on the Adjoining Owners land, to a depth that is lower than the bottom of those foundations.


The above notices all have a notice period associated with them. That is, the Building Owner is stating that they propose to carry out the notifiable works after a time period set by the Act. For Section 1 & 6 notices this period is one month, for a Section 3 notice it is two months. Additionally, if surveyors are appointed, bringing the process to a conclusion can take several months. Therefore, it is important to ensure that sufficient time is allocated for this process to run its course before any construction work is planned to commence.


Content Requirement for Notices

What should be included in a notice? Generally speaking, notices can be quite simple in format, but they must be in writing, either on paper or electronic format. Often we are asked if a brief chat with the Adjoining Owner is sufficient. Sadly this is not recognised by the Act as a valid means of service of notices.


For a Party Structure Notice the Act states that the notice should include;

  1. The Building Owner’s name and address,

  2. The nature and particulars of the proposed works,

  3. The date on which the proposed works will begin.

  4. Technically, a dated signature is not mentioned in the Act but it can help avoid any issues over when the notice was served.


Fortunately, there are free templates that can be downloaded from the official GOV.UK website that can help ensure the notice is presented in the correct way. However, in our experience, the vast majority of notices that are served by homeowners using the free template are incorrect, often making them invalid. Therefore, we would recommend that you consider discussing the notices with a surveyor before you serve, just to be sure. Alternatively, most surveyors offer to serve at a very reasonable rate to avoid the hassle and delay caused by invalid notices.


Validity & Timing of Notices

It’s important to remember that these types of notices are only valid for 12 months from the date of service. If the works that they relate do not commence and, are thereafter prosecuted with due diligence, the notice will cease to have effect. So whilst serving notice early is important, the timing of the works does need to be considered to ensure any agreements that are made don’t elapse and the process having to be started over.


Frequently Asked Questions (FAQ's)

Can I rely on a brief conversation with the Adjoining Owner instead of serving a written notice?

- No, the Act does not recognise verbal communication as a valid means of serving notices. Notices must be served in writing, either on paper or in electronic format (with permission from the recipient to receive electronic communication).


Are there templates available for serving notices?

- Yes, free templates can be found on the official GOV.UK website. However, it's advisable to consult a surveyor to ensure the accuracy and validity of your notices. Mistakes are often made that make notices invalid, resulting in lost time and possible additional expense.
