The Wiring Regulations do allow you to run cables concealed without
either the 50mm depth or steel protection either vertically or
horizontally from wiring accessories - i.e. light switches and power
sockets etc.

You only need the depth or protection if you want to run them at an
angle or in other places - e.g. if you went horizontally from a
switch and then up without there being a wiring accessory at the
point where the cable changes direction.

Not quite. You don't need an accessory at the point of direction
change provided that that point is at the intersection of
vertical/horizontal lines from accessories.

eg fixed pitch font


-----A-----+-----


-----+-----B-----


You can cable between A and B via either route through the + points.

Are you sure?

The OSG and Whitfield illustrate and seem to say that a direction
change without an accessory can only happen if the point of direction
change is within one of the corner or top of wall 150mm bands; not
even where a cable goes down vertically from an accessory to the
floor.
