Quick summary

You need a party wall surveyor if you require a party wall agreement, which is necessary when building within three metres of a shared boundary or wall and your neighbour doesn’t give consent. Hiring one can cost from a few hundred to over a thousand pounds, depending on the project size, and is essential to protect both parties during construction.

If your project is affected by a party wall matter, you might have heard the term ‘party wall surveyor’ batted about. But how can this professional help your home and do you even need one?

Let’s find out…

What is a party wall?

A party wall is a wall, boundary, or outbuilding that you share with another household. These are common between terraced and semi-detached houses but can also affect detached properties if you share a garden wall or invisible boundary line.

While it can be quite easy to spot a shared party structure, such as a wall between two terrace properties, it can be difficult to spot shared boundaries. For this reason, we always recommend having an architect on board, who will be able to spot these issues ahead of time and advise you when to act.

Work you must tell your neighbour about

A party wall notice is required if you’re building anywhere within 3ms of a party wall, including shared boundaries.

The notice must be served at least two months before any construction takes place and be given to all legal owners of any building affected by your proposed build. Under the Party Wall etc. Act 1996, neighbours have 14 days to respond.
