Hi all, the electrician called yesterday he tested the main fuse trip switches with all computer equipment un plugged, then started with my kitchen equipment.
On testing my electric plug in kettle, he found something there and said that even though the kettle was not being use (as in the night time cut outs) because it was plugged in it could cause the trip.
Have bought a new kettle and hopefully problem solved. Thank you for all your help. Mick.
