Once again, thanks for all the feedback/suggestions. Good call on the oven clock - didn't consider that!.
The walking over floorboards I have considered, even tried a walk-around whilst I was there to no avail! Like others, I just hate not being able to get to the bottom of this type of problem.
I'll keep you posted if I manage to resolve it.
Regards
