Safe Zones - but do go to sockets or switches and are all vertical or
horizontal. Should be easy to detect - a decent magnet would do it!


They are in safe zones then as they extended from switches and sockets
in the vertical and horizontal directions.

Yup, like in the pictures:

But some aren't within 150mm of edges.


But you said they were vertical and horizontal not bent.

They are straight but not within 150mm of an edge.

They don't need to be...

A safe (or in this context a better word might be "expected") zone is
one of three separate and distinct areas:

1) Horizontally or vertically intersecting with the location of a
visible electrical accessory. Hence the position of the zone is not a
fixed place, but is defined by where the accessory actually is. So if
you see a socket you know not to drill directly above, below, or to
either side of it. That socket might be 2m from the nearest corner - but
it still defines a zone around it.

2) At the intersection of two vertical walls - this applies even if
there is no visible accessory. So don't go drilling in the corner beside
a chimney breast even if you can't see a switch or socket.

3) At the intersection between wall and ceiling.

Basically, if installing cables, they need to be in a least one of these
zones. They can be in more than one, but there is no benefit or
requirement for this. Hence avoid running cables at odd angles, or
changing direction of them mid run.

Thanks, this clarifies it.
There's only one cable that's diagonal and that is clipped to the surface -
and avoided a re-wire.
