The Party Wall Act 1996 is a crucial piece of legislation in England and Wales, designed to protect the structural integrity of shared walls, also known as party walls, in properties such as semi-detached houses and terraced homes. This law plays a significant role in resolving potential disputes between neighbors while ensuring safety and compliance when carrying out building work that could affect these shared structures.
It’s important to note that The Party Wall Act 1996 does not extend to Scotland or Northern Ireland, where different common law principles apply to party wall matters.

Do I Need a Party Wall Agreement
If you’re planning any type of construction or soundproofing work near or on a shared wall in West Sussex, you may need a Party Wall Agreement. This is essential to avoid potential disputes with neighbors, especially when undertaking major works that could impact shared structures.
To begin, you must inform your neighbors about your plans by serving them with a Party Wall Notice. Following this, a formal Party Wall Agreement must be created in writing, outlining the specifics of the work. Builders or architects involved in the project can provide guidance on this process, although they cannot serve the notice for you.
Works Requiring a Party Wall Agreement
For West Sussex homeowners looking to improve their soundproofing, the following works require a Party Wall Agreement:
-
Extensions on or near party walls
-
Wall or floor soundproofing between homes or flats
-
Excavation within 3–6 metres of a shared wall
-
Loft conversions involving structural changes
-
Damp proofing or wall thickening for insulation
If your project affects a shared wall, it’s best to get professional advice and neighbour consent first.


Works That Do Not Require a Party Wall Agreement
Not every soundproofing job requires a Party Wall Agreement. Some minor works may not trigger the need for an agreement, including:

Drilling into party walls to install shelves or kitchen units

Adding plaster or replacing wiring or sockets for improved soundproofing or electrical needs

Replacing or adding soundproofing materials without altering the structural aspects of the wall
