Hi Danny
Weather currently in the UK: High of 6 degrees and a low of -6
hehe!.. dont want to put you off but you will find it very cold in the winter but its nothing a nice hat and scarf cant fix.. and with the cold weather comes snow so its fun fun fun! especially if you do locate yourself out in the countryside, you'll be sledging to work and back
If you are after a nice city / countryside mix lifestyle may i recommend working in Edinburgh... its by the sea, surrounded by countryside and a gorgeous city centre and full of history. Also with it being a city there will be plenty of jobs and stuff to do with your time like the old scottish pasttime of drinking!!
