When you’re planning construction or renovation work in London that affects a shared wall, boundary, or structure between properties, you’ll likely need the help of a Party Wall Surveyor. These professionals ensure that you comply with the Party Wall etc. Act 1996, a piece of legislation designed to protect the interests of both building owners and adjoining neighbors during structural works.
In this article, we’ll explore who party wall surveyors are, when you need one, what they do, and how to find a qualified expert in London.
What Is a Party Wall?
A party wall is a wall that is shared between two separate properties. Common examples include:
The wall between two terraced or semi-detached houses
A garden wall built along a boundary
Floors or walls in flats that separate different units
The Party Wall etc. Act 1996 applies not only to actual walls but also to boundary lines and certain types of excavation work near neighboring buildings.
When Do You Need a Party Wall Surveyor?
If you’re a homeowner or property developer planning work that affects a shared wall or boundary, you must serve a Party Wall Notice to your neighbor. You will need a Party Wall Surveyor if:
Your neighbor dissents (disagrees) to the notice
You’re carrying out excavation within 3 to 6 meters of your neighbor’s foundation
You are building a new wall on the boundary
You’re cutting into or modifying a party wall
The surveyor’s job is to act independently to resolve disputes and ensure that the building work does not damage the adjoining property.
