Understanding the Party Wall Act 1996: A Plain English Guide
If your planned building work could affect a shared wall, boundary wall, or involves digging close to a neighbourâs foundations, you must check the Party Wall Act 1996. Donât skip this step. Follow the rules and you reduce the chance of delays, damage claims, and arguments that slow the job down.
This guide tells you what the Act covers, when it kicks in, how to serve notices, what happens when neighbours object, who pays, and practical things to do to keep the project moving.
What the Act actually covers
The Party Wall Act 1996 applies in England and Wales. It sets out a legal process for certain kinds of work that affect party structures. A party structure means more than just a wall on the property line. It includes shared walls, boundary walls used by both properties, walls that sit on the boundary but belong to one owner, and even floors or ceilings between flats.
If the work affects one of those things, you need to follow the Act. If you ignore it, you do not just risk a neighbourâs complaint. You risk being stopped by a surveyorâs award, being ordered to make repairs, and paying costs. So check early.
When the Act applies â the practical tests
The Act applies to three main categories of work. First, structural work to a party wall. Examples include cutting into the wall, inserting beams, pulling out chimney breasts, raising or lowering the wall, or demolishing and rebuilding parts of it. Second, building a new wall on a boundary line. Third, excavations close to a neighbourâs building where the depth or distance could affect their foundations. There are detailed distance and depth tests in the Act, but the quick rule is this: if you are digging within a few metres of a neighbour and going deeper than their foundations, treat the Act as relevant.
If you are unsure, donât gamble. Treat the work as likely to be covered and start the notice process.
Notices: how to tell your neighbour and when
You must serve a written notice on any neighbour affected by the proposed work. This is not a casual chat over a fence. The notice must include enough detail about the work for the neighbour to understand what you plan and when you want to start. For most party wall work you should give at least two monthsâ notice. For certain excavation work the notice period is one month. The notice should say the planned start date and include drawings or clear descriptions of the work.
A neighbour has three possible responses. They can consent in writing. If they consent, you can proceed without a formal award. They can dissent, in which case the dispute resolution process starts. Or they can ignore the notice. Inaction counts as dissent. If they do not respond within the relevant time frame, you should assume you need to move to appointing surveyors.
Surveyors and the Party Wall Award
If there is dissent, the next stage is surveyors and then a Party Wall Award. You and your neighbour can agree a single surveyor, called an Agreed Surveyor, to act for both of you. More commonly, each party appoints their own surveyor. If two surveyors cannot agree, they appoint a third surveyor to resolve the dispute.
The surveyor(s) inspect the properties, record existing condition, consider the proposed work, and then issue the Party Wall Award. The Award is a legally binding document. It sets out what can be done, how it must be done, when it can be done, and who pays. It will also include condition schedules and any requirements to protect the neighbourâs property or access their land for inspections and works.
Who pays
Generally, the building owner â the person carrying out the work â pays the surveyor fees and related costs. That normally includes the building ownerâs own surveyor, the neighbourâs surveyor, and a third surveyor if one is needed. The building owner also pays for making good any damage caused by the works. There are exceptions, but the common expectation is that the person doing the work meets the costs associated with the party wall procedure.
Rights and responsibilities â what each side can expect
As the building owner you have a right to carry out the work after following the correct procedure. You also have the right to enter the neighbourâs land to carry out the works, subject to reasonable notice and any conditions in the Award. You must do the work competently, protect the neighbourâs property, and repair any damage.
Neighbours have a right to notice, to have their property protected, and to have any damage made good at the building ownerâs expense. They are also entitled to a fair Party Wall Award that reflects a reasonable balance between the need for the work and the need to protect the neighbourâs property.
Common mistakes that slow projects down
A lot of problems come from assumptions. People assume verbal consent is enough. It is not. People assume the work is small so the Act does not apply. Sometimes it does. People leave party wall matters until the last minute. That causes delays and may push the whole build back while surveyors are appointed and an Award is prepared.
Another frequent error is trying to redesign around the Act without proper advice. That can create weaker designs or still leave you exposed to claims if damage happens.
Practical steps to get it right
Start the party wall process as soon as your plans are fixed. Do it before contractors are booked or demolition starts. Give clear, complete notices. Use experienced party wall surveyors. Keep records of the property condition with dated photos or a schedule of condition. Communicate with your neighbour. Honest, clear communication does not replace the formal process, but it lowers the chance of hostility and can speed agreement.
If the neighbour objects, accept the surveyor process and avoid escalating things personally. Let the surveyors deal with technical points. This saves time and usually money.
Cost considerations
Budget for surveyor fees and delays. Surveyor costs vary by region and by complexity. For basic jobs the fees may be modest. For complex basement or structural work, fees can run into several thousands of pounds. Consider these costs part of doing the job properly. The alternative is a risk of higher costs later through damage claims or legal action.
Final practical checklist
Before you start building, confirm these items. First, identify whether your work affects a party structure. Second, prepare a clear written notice with basic drawings and a proposed start date. Third, serve the notice in good time. Fourth, agree on a surveyor or be ready for the surveyor appointment process. Fifth, document existing conditions and keep records during the work.

Conclusion
The Party Wall Act 1996 is there to manage risk. It protects neighbours and allows building work to proceed with clear rules. It looks like red tape at first. But in practice it removes ambiguity, gives a defined route to resolve disputes, and reduces the chance of costly interruptions. Do the notices properly, choose experienced professionals, and keep good records. That approach keeps the project moving and keeps neighbours from becoming problems.
