Party walls and boundaries

A crack in this terrace party wall continues into the render next door. Has the survey made an award?

No. A crack that appears to run into next door’s render is still only what the surveyor could see from this side and from the street. It is not an inspection of the neighbour’s house, not a party-wall award, and not a decision about who pays. The Act applies, where it applies, in England and Wales only, and the survey does not serve notice.

What is the fuller explanation?

GOV.UK’s procedure is about certain works: on or at a boundary, to a party wall or party structure, and excavation near a neighbour. A crack is not one of those works. It can be a symptom of movement, of the render, or of an old repair. The survey should describe width, direction and whether it is fresh, within the limits of one visit. It cannot monitor the crack, and it cannot walk into next door to see the other face of the same wall.

Who repairs a shared wall is a matter for the solicitor and, if work is proposed, for the right local procedure. Do not send an English award form because the render lines up. Do not ignore the crack because no award exists. Condition and procedure are different. Scotland and Northern Ireland are outside this Act. A continuation of a crack across a boundary does not import the Act into those countries.

What should you ask your surveyor?

  • What did you see of the crack on this side, and what could you see of next door’s render?
  • Did you go into the house next door?
  • Are you issuing a party-wall award?

What are the typical next steps?

  1. Describe the crack to anyone you ask about movement. Do not call it an award.
  2. Ask the solicitor who is likely to deal with a shared wall if repairs are proposed.
  3. Do not use the English and Welsh forms in Scotland or Northern Ireland.

Costs vary with the building and with who you instruct. Where this page does not cite a published figure, ask the surveyor, a relevant specialist, or your solicitor for a written quote. Do not treat a forum average as the price.

Also asked about this

Does the crack crossing the boundary prove the neighbour caused it?

No. A line in render does not allocate blame. The survey did not investigate next door.

Is planning permission the missing paper?

Not for a crack. Planning does not replace the Act, and neither document is created by describing a crack.
