Do I need a party wall notice?

Extensions, lofts, basements and boundary walls next to a neighbour often fall under the Party Wall etc. Act 1996. Answer a few questions and we'll tell you which notices you need, when to serve them, and your earliest lawful start date.

This checker needs JavaScript. Without it, here is the short version: work to a wall, floor or ceiling you share with a neighbour needs a Party Structure Notice two months before you start; a new wall on or up to the boundary, or digging within 3 metres (sometimes 6 metres) of a neighbour's building, needs one month's notice. Read the GOV.UK explanatory booklet.

How this works

The checker follows sections 1, 2 and 6 of the Act and the GOV.UK explanatory booklet. It covers the common home-improvement cases. Unusual sites (shared access ways, flying freeholds, commercial neighbours) need a surveyor's eye. Nothing is stored on our servers until you ask us to generate a notice pack or request quotes.
