About PartyWallChecker
A free tool that tells homeowners and their neighbours what the Party Wall etc. Act 1996 actually requires — in plain English, in about 90 seconds.
How the verdict is decided
The result comes from tested, deterministic code that follows the Act and the government's explanatory guidance — not from a chatbot guessing. When anything is unclear, it errs toward caution and tells you to confirm with a surveyor, rather than risk a false "no notice needed".
What's free, and what isn't
The full verdict is free, always — no signup. If you want the paperwork done for you, an optional £39 pack generates your ready-to-serve notices. And if you'd rather hand it to a professional, we can introduce one vetted local surveyor, free to you.
