Building near your neighbour? Or received a letter about it?
Find out exactly what the Party Wall Act asks of you, in plain English.
that wall in the middle? you share it.
What the free check covers
The checker asks about six things, in plain English: the type of project (a loft conversion, extension, basement, removing a chimney breast, or a new wall on the boundary), where the work sits in relation to the wall or boundary you share with next door, and whether you will be digging within 3 or 6 metres of a neighbouring building. Multiple choice, about 90 seconds.
You get a clear answer on whether the Party Wall etc. Act 1996 applies, which notice or notices you would need to serve, how much warning the law asks you to give (one or two months, depending on the work), and who usually pays for what. It covers England and Wales only, and when your answers leave room for doubt it says so and points you to a surveyor rather than guessing.

What the free check tells you about your notice
The check reads your letter: which section of the Act it cites (1, 2 or 6), whether it arrived with everything a valid notice needs, and how the dates stack up. Four quick taps, no signup.
You get your notice explained in plain English, your three options spelled out, the 14-day clock that's already running, and the fact that the building owner — your neighbour — normally pays for your surveyor. If the notice looks defective, it flags that too.
