My 1980s house has compressed straw dryling plaster boards for the
upstairs internal walls.

Much easier to fit things into than brick walls.

When fitting sockets to one room I unexpectedly but conveniently found
a cable channel running vertically in the panel.

They are very useful.

Now I want to find one of these in another room - I'm guessing that
the only way is to dig a horizontal channel until I find one (I've
already decided where the pattress boxes will go so I'll need to cut a
channel anyway), but how far apart are they (don't want to find I go a
long way in one direction only to find that there is one the other way
very close!

If you go up in the loft you may be able to see the top of the board
and by inspection find the separation of the channels.

Alternatively a double box is generally wide enough to find one
channel somewhere along the width.
