Our Gas and Leccy combined is £160 pcm.
Depends, is it the size of Windsor Castle? 
My old 1970 built detached was ~£100pcm combined, the new larger 1930s built detached looks likely to be ~£120pcm and I think my electric is likely to be above average given we pound the dishwasher, tumble drier and have a bank of computers running 24x7..
Ooo, Possibly not awful then. The place is about 2900 sq ft and has its original (single glazed and draughty) sashes. I have insulated where possible though. When we bought it, it was £200/month, and still bogging freezing!
BUT we have a Raeburn and also a log burner
Great fun being able to play with fire as blokes like to do 
Solid fuel Raeburn? Bet that keeps you busy! We were going to install at least one log-burner, but seeing as we're selling up shortly, seems like a poor investment!
