I use a surge protector into which I plug a four socket extension lead which has my machine, a switched on lamp and often my iron plugged in. When I leave my sewing room I always unplug the surge protector, and the lamp helps me remember to turn everything off on the one switch.
I am glad that here in South Gloucestershire, we rarely have storms so bad that we need to unplug everything, but hopefully the surge protector does its job on the odd occasion that they do occur.
