I find it SO hard to believe it can get so cold, but my husband assures me that our flat was like a fridge last winter (he sat in the bath for hours before going to bed just to warm up! lol). It's the way the properties are built i.e to keep OUT the heat!

But now I have heard so many say the same I guess I have to believe it and grab a heater or two as soon as I see any appear in the shops!
