kitchen trip switch goes at night?

It could be a faulty appliance, fridge or freezers start and stop 24 hrs a day so plug them in somewhere else and see what happens, turn off outside lighting etc then see what happens,
If you need to call a sparks this will helpmhim as you have done some problem solving already which in turn could make it cheaper for you ;-)

is there any chance it could be mice as they like the taste of cable plastic or is there an outside PIR which could be triggered by wildlife.Only an electrician has any chance of narrowing it down
