Hi Karlie. I'm in Southampton so probably one of the warmer parts of the UK. I intend to fill their hutch now with as much hay as I possibly can and maybe invest in a snugglesafe. I also have another hutch box that I might put it, but I think they'll be ok. Shed is all insulated and if it gets really cold I might consider some sort of low power safe heater to take the chill off but I think they should be fine once they've grown their winter coats.
