Get the right party wall notices prepared and served on your neighbours

Three party wall notices fanned out beside a sealed envelope, with a pair of attached houses and a surveyor with a clipboard

For homeowners in England and Wales about to build next to a neighbour. Explain your project and compare quotes from party wall surveyors who can prepare the notices, serve them and track the replies.

Before work starts on or near a shared wall, the Party Wall etc. Act 1996 usually asks you to give your neighbours written notice. There is more than one kind of notice, and each has its own minimum notice period, so choosing the wrong one, or leaving an owner off the list, can hold up your build. A party wall surveyor reads your drawings and works out which notices apply. They prepare each one with the plans and start date it needs, serve it on every affected owner and keep a record of when it was delivered and when replies are due. The Act covers England and Wales, while Scotland and Northern Ireland work differently.

How a professional can help

Choosing the right notice: A surveyor checks your drawings against the three main kinds. A party structure notice covers work to a shared wall. A notice of adjacent excavation covers digging near next door. A line of junction notice covers a new wall on the boundary. One project can need more than one.
Preparing a valid notice: They draft each notice with the details the Act expects: your name and address, the property, a clear description of the work, the plans and the date you plan to start. A notice with gaps can be open to challenge.
Finding every owner who needs one: Notices go to every owner of the neighbouring property, which can include a freeholder and long leaseholders as well as the person who lives there. A surveyor helps you work out who they are, using the Land Registry where necessary.
Serving it and keeping proof: Notices are delivered by hand or sent by post, and the date matters because every deadline runs from it. Your surveyor keeps a dated record of how and when each notice was served, in case anything is questioned later.
Tracking replies and the next step: A neighbour can consent in writing, dissent (say they do not agree) or say nothing. For most notices, if there is no reply within 14 days a dispute is treated as having arisen. Your surveyor tracks the dates and moves on to the right next step.
Keeping notices valid and in date: Serving a notice far too early, or changing the design after it goes out, can mean serving again. Your surveyor ties each notice to a realistic start date and tells you when a change to the plans needs a fresh or amended notice.

Is this right for you?

You’re planning a loft conversion, extension or basement in England or Wales and your home shares a wall or boundary with a neighbour.
You’re not sure which notice, or how many notices, your project needs.
Your builder or designer has told you to serve notice before work starts.
You want your notices prepared and served correctly, so they don’t hold up your build.
You’re a landlord or developer with several neighbouring owners to notify.

How the project usually runs

Review the drawings: The surveyor studies your plans and structural design to see whether the work touches a shared wall, sits on the boundary or digs near a neighbour’s foundations, and which owners will be affected.
Draft the notices: Each notice is written for its type of work, with a description of what you plan, the relevant plans and sections, and a proposed start date that respects the minimum notice period.
Serve and record: Notices are delivered to every owner and each delivery is dated and logged. The minimum is two months for work to a party wall and one month for excavation or a new boundary wall.
Neighbours respond: Each neighbour can consent in writing or dissent, and for work to a party structure can also serve a counter notice. With consent, work can go ahead. If they dissent, or stay silent for 14 days, surveyors are appointed. A line of junction notice differs: without consent, the wall goes wholly on your land.
Consent, or a party wall award: With consent, a schedule of condition is still sensible. Where there is a dispute, one agreed surveyor or two surveyors prepare a party wall award that sets out how and when the work is done.

What affects the cost

How many notices the project needs, since a loft, an extension and a basement can each call for a different combination.
How many neighbouring owners there are, including freeholders and long leaseholders in blocks of flats.
Whether your neighbours consent or a dispute arises, because surveyors are then appointed and there is more work to do.
The quality of your drawings and structural design, as clear plans make notices quicker to prepare.
How tight your timetable is, and whether notices need to be reissued after a design change.
Where surveyors are appointed, the building owner normally pays the reasonable fees on both sides, so ask each quote what it covers.

Notices, the Act and where it applies

Party wall notices come from the Party Wall etc. Act 1996, which covers England and Wales. Scotland and Northern Ireland have different rules, and party wall surveyors across the UK can tell you what applies where your property is.
A notice doesn’t replace planning permission or Building Regulations approval. Each is a separate process, and having one doesn’t remove the need for the others.
The minimum notice is two months for work to a party structure and one month for adjacent excavation or a new wall on the line of junction.

Questions people ask

Which party wall notice do I need?

It depends on the work. A party structure notice covers things like cutting beams into a shared wall or removing a chimney breast. A notice of adjacent excavation covers digging near a neighbour’s foundations, and a line of junction notice covers a new wall at the boundary. Some projects need more than one, and a party wall surveyor can confirm which apply to yours.

How far ahead must I serve notice?

At least two months before work starts for a party structure notice, and at least one month for a notice of adjacent excavation or a line of junction notice. Those are minimums, so serve earlier if your builder is waiting. Notices also have a limited life, so don’t serve them far too early either.

Can I serve a notice myself?

Yes. The Act doesn’t require a surveyor to serve a notice, and guidance with example wording is published online. The risk is a notice that is missing information or isn’t served on every owner, which can cost you time later. A surveyor can prepare and serve the notices for you.

Does a notice mean my neighbour can stop my building work?

The Act is about how the work is done rather than whether it can go ahead. A neighbour can consent, or dissent and have surveyors set the terms, but they can’t simply refuse work the Act gives you the right to carry out. They can ask for protections such as a record of their home’s condition and agreed working hours. A surveyor can explain how this applies to your project.

What happens if I forget to serve notice?

Starting work covered by the Act without notice can lead to an injunction, which is a court order to stop, or to a claim for damage. If you have already started, have your builder make safe anything already opened up, hold off further work covered by the Act and speak to a party wall surveyor promptly. They can tell you what can be done next.
