Party wall

When do I need a party wall agreement?

Cutting into a wall to insert a beam for a loft conversion.
Altering the height of a party wall.
Demolishing and rebuilding a party wall (often to carry an extension).
Underpinning a party wall.

How do I go about getting a party wall agreement?

Firstly consult your neighbours well in advance to avoid disputes further down the line.
Secondly, give notice in writing at least two months before the work is due to start to all owners about what you intend to do, when you intend to do it, and how it will impact on them (you could include a copy of any plans).
Thirdly the owners must give your permission in writing before you start.

What if I want to start work on a party wall before two months?

Any adjoining owners may agree to work starting earlier but are not obliged to. Agreement from adjoining owners must be gained in writing before you start.

What happens if a neighbour does not agree to a party wall agreement?

An “agreed surveyor” will need to be appointed to draw up an “award”. This award will typically set out the work to be done, how and when it will be carried out, and will include a report on the existing condition of the adjoining property (in case of a dispute arising about damage after the work has been completed).
Alternatively each party may appoint their own surveyor (although as the cost is usually incurred by the person who is proposing the work, it may be in their interest to use an agreed surveyor.)
