Party Wall Act

Some types of building work are not controlled by building regulations. However, the work may still be covered by the Party Wall etc Act 1996.

A party wall is a wall or structure that sits on, or is shared by, the boundary between two properties.

The Party Wall etc Act is separate legislation and has different requirements to building regulations. It applies to work involving party walls, and to excavation and construction near neighbouring buildings or structures.

In some cases, both the Party Wall etc. Act and building regulations will apply to the same work.

Works to an existing party wall

Listed below are examples of some of the most common types of works carried out where notification is required under the Party Wall etc Act:

• cutting into a party wall to support a structural beam, for example when creating an open‑plan room or carrying out a loft conversion
• raising the height of the wall and/or increase it's thickness
• inserting a damp proof course
• underpinning the whole thickness of the party wall, or along part or all of it
• demolishing and rebuilding the party wall.

Minor works such as installing shelves or wall units, replacing recessed electrical sockets or re-plastering are generally regarded as not necessary for notification to neighbours.

You will need to give at least two months' notice before starting the work. The adjoining owner may agree to allow the works to start earlier.

Your neighbours

We would advise discussing your planned works with the adjoining owners to your property before giving any notice. After the discussion you can then inform them in writing and this must include:

• your name and address (joint owners must also be named)
• address of building to be worked on
• full description of the works you are proposing, which can be in drawing form
• when you propose to start works.

If you are doing works which are not with an adjoining neighbour there is no requirement under building regulations to consult neighbours, however it can be courteous for you to do so.

Objections may be raised under other legislation, particularly if your proposal is subject to planning permission under the Town and Country Planning Acts.
