I were changing a landing light fitting t'other day & pulling the downstairs
fuse left it on.

I thought the landing light took its power from the 'downstairs' lights?

I've never come across that arrangement. It would appear to me to be a
dangerous practice to have an upstairs light on a circuit marked
'downstairs'

Is there an accepted way of wiring these up of is either acceptable?

I would expect the hall light to be on the downstairs light circuit and
the landing light to be on the upstairs cisuit. That way, if one circuit
fails, you still have light in the stairwell, which is one of the most
dangerous places in a house not to have any light. I also have an
emergency light above the stairs, in case of a total power failure.
