Why you need a party wall agreement, and how it works

When planning construction or renovation work that involves a shared property boundary or party wall, understanding the importance of a Party Wall Agreement becomes crucial. Whether it’s working on an existing structure, modifications to a party wall, or excavation close to a neighbour’s foundation, the Party Wall etc. Act 1996 mandates that your neighbours must be notified of such intentions. This is where a party wall surveyor comes in. Look for one with real construction experience behind them and membership of a relevant body, such as the Chartered Institute of Building or the Faculty of Party Wall Surveyors. Their job is to keep the project inside the law and moving.

Party wall notices

Before embarking on your project, serving a Party Wall Notice to your neighbours is a legal requirement. This notice informs them about the work you intend to carry out. It’s not just a formality. It’s a critical step in fostering good relationships with your neighbours. While it’s recommended to discuss your plans with them beforehand, which can sometimes lead to quicker and more favourable responses, the official agreement must be documented in writing. The notice period depends on the work: two months for a party structure notice, one month for a line of junction or excavation notice. Once it is served, your neighbour has 14 days to consent or dissent.

When a neighbour dissents, the award

A dissent leads to a party wall award. The surveyor assesses the party wall or the boundary and prepares the documentation that forms the award, setting out what can be done and how. This process involves close coordination with surveyors from the neighbouring side to ensure that all concerns are addressed.

Your rights, and what a neighbour can do

It’s important to note that neighbours cannot prevent you from conducting legal and approved construction work on your property. However, the Party Wall Agreement process gives them a voice in how and when the construction occurs. Successfully navigating this process allows you to commence construction, provided all other planning and design phase requirements are met.

Getting the right advice

An experienced party wall surveyor is not optional on a project near a shared boundary. They will take you through the legal steps and, just as importantly, keep the relationship with the neighbour civil while the work runs.

We coordinate the surveyor alongside building control and the structural design as part of the same contract, so the notices go out on time and the programme is built around the award rather than interrupted by it.
