What is the Party Wall Act 1996?

The Party Wall Act 1996 is legislation that provides a framework for preventing and resolving disputes in relation to party walls, boundary walls, and excavations near neighboring buildings. If you're planning building works in Brentwood, Chelmsford, Romford, or anywhere in Essex that affect a shared structure, you must comply with this Act.

A party wall is any wall or structure that separates two properties and is shared by both owners. This is most common in semi-detached and terraced properties throughout Brentwood, but can also apply to boundary walls and structures in gardens.

Key Point

The Party Wall Act applies across England and Wales. It's designed to protect the interests of both the building owner (who wants to carry out works) and the adjoining owner (whose property may be affected).

Types of Party Structures

  • Party Wall: A wall standing on the boundary between two properties, forming part of a building
  • Party Structure: A wall or floor partition between buildings belonging to different owners
  • Party Fence Wall: A wall (not part of a building) standing on the boundary between two properties
  • Boundary Structures: Walls or fences directly on the property line

When Do You Need a Party Wall Surveyor?

You must serve a party wall notice to your neighbor (adjoining owner) if you're planning to carry out certain types of building works in Brentwood or Essex. Our party wall surveyors regularly handle these situations for properties throughout the region.

Works Requiring Party Wall Notice:

Building on or Altering a Party Wall

Including inserting damp proof courses, raising walls, or cutting into walls

Rear Ground Floor Extensions

Single-story extensions built close to or on the boundary line

Loft Conversions

Work affecting the party wall in semi-detached or terraced properties

Underpinning

Common in Brentwood

Mid-terrace and semi-detached properties are particularly common in Brentwood, Shenfield, and throughout Essex. If you own one of these property types, you'll almost certainly need to comply with the Party Wall Act for any significant building works.

The Party Wall Survey Process

Understanding the party wall process helps you plan your building project timeline effectively. Our chartered surveyors in Brentwood can guide you through each step.

1

Serve Party Wall Notice

You (the building owner) must serve written notice to your neighbor (adjoining owner) at least 2 months before starting work on a party wall, or 1 month for excavations. The notice must include details of the proposed works.

2

Neighbor's Response

Your neighbor has 14 days to respond with either consent or dissent. If they don't respond within 14 days, it's deemed a dispute and you'll need to appoint surveyors.

3

Appoint Surveyors

If there's a dispute, three options exist: both parties appoint a single agreed surveyor, each party appoints their own surveyor, or (if your neighbor doesn't appoint) you can appoint on their behalf after 10 days.

4

Schedule of Condition

The party wall surveyor(s) will inspect the adjoining property and prepare a detailed schedule of condition, documenting the property's current state with photos and descriptions. This protects both parties.

5

Party Wall Award

The surveyor(s) prepare a party wall award - a legal document setting out what work can be done, how it will be done, and when. This is binding on both parties.

6

Works Proceed

Once the award is agreed, building works can commence. The surveyor may carry out interim inspections during the works.

7

Post-Completion Inspection

After works complete, a final inspection confirms whether any damage occurred. If damage is found, the award specifies how it should be remedied.
