Well I have one small fridge, one large fridge/freezer, 2 small freezers and one large freezer. And they're all almost full of food, meat, veg. and fruit from last year, baked goods etc.
I defrost the freezers when the ice starts to force the door open. The fridges get emptied and cleaned once a year.
The problem comes if we have a long power cut, as happened after a storm in 2009. A friend lent us a generator to keep the contents cold, otherwise it would have meant a big financial loss.
You can insure against this.
I've got another 'keen'... Ouch!
