Get a full materials list for a fence run. Enter the length and height and the calculator returns panels, posts, gravel boards, postcrete, fixings and post caps, using UK standard component sizes.
One more than the number of panels. A 12m run using 1.83m panels needs 7 panels and 8 posts.
Around a quarter to a third of the total post length, so roughly 600mm for a 1.8m high fence. Go deeper on exposed sites and in loose or sandy ground.
In England, a fence up to 2m generally does not need planning permission, dropping to 1m where it fronts a highway. Listed buildings, conservation areas and boundary agreements with neighbours can all change this, so check before you build.
