Chimneys and parapets
A cowl oversails the boundary. Has a Party Wall Act notice already been served by this inspection?
No. This inspection has not served a Party Wall Act notice. A cowl that oversails the boundary was recorded as a physical fact: part of this building projects past the apparent line. Noticing that projection is not a notice under the Act, and the surveyor was not appointed to serve one. Whether the Act applies, whether the cowl is a trespass, and whether an older notice exists are legal points. The report can describe the cowl and the apparent oversail. It has not started any statutory process and has not decided the boundary.

What is the fuller explanation?
The Party Wall etc. Act sets a notice procedure for defined work and some projections. Neighbours and people appointed under that Act then follow it. A home survey is a different instruction. The surveyor looked at the building for you. Serving notices and deciding jurisdiction were not part of the visit. A cowl or flue terminal that sticks out is easy to see and easy to over-read. Seeing it does not mean a notice was served on the day, or at some earlier time. The observation stops at the projection.
Tell your solicitor about the oversail and ask whether any Party Wall notice, award or neighbour's consent is already in the papers. Do not tell the neighbour that this survey was a statutory notice. If the cowl needs to be moved or regularised, that is a legal and building matter, not a step the inspection has already taken. The survey has not decided the fitting must come down. It has recorded an apparent projection and left the legal consequences alone.
What should you ask your surveyor?
- What does the report say oversails, and on which side of the house?
- Is there any Party Wall award already in the legal pack?
- Has the survey left the line of the boundary undecided, as it should?
What are the typical next steps?
- Treat the oversail as an observation, not as a notice that has been served.
- Ask your solicitor to look for any existing Party Wall papers.
- Do not contact a neighbour as if this inspection had started the Act.
Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.
Also asked about this
Does an oversailing cowl always bring in the Party Wall Act?
Not automatically, and this survey has not decided that it does. The Act covers defined work and rights. A cowl across a line might be another kind of boundary issue, or it might fall under the Act. Your solicitor, not the home survey, sorts which regime applies. Do not assume a notice was required merely because the fitting projects.
Can the surveyor serve the notice next week under this same report?
Only if someone is separately appointed to do that, which this home inspection was not. The visit did not serve a notice and cannot be relabelled as one afterwards. If a notice is needed, your solicitor should say so and the right person should serve it. The PDF is not that document.
