BTW: minus bloody 3 degrees centigrade outside the house.
Decided to switch the fridge off and leave all the food outside. Doing my bit to reduce global flipping warming! 
I don't think it got above that all day here.
Funny though, it didn't feel that cold as I was swapping wheels.
The problem I have now is the snow is so deep that tyre tracks have made ruts...with the bit in the middle now using my front spoiled as a snowplough. It's so cold, and the snow so frozen, I'm worried about cracking the front bumper!
Maybe a lowered GTI isn't the best transport in deep snow.
