Bastards 
I suppose I should have noticed but tbh water is one of those things I just don't notice - I've always paid my bills on monthly DD in the past.
Yesterday I got a letter which says 'Dear Ms Mayor, I am writing about your change of address. We have opened an account for your new property from 1 November 2010. A bill is enclosed. Blah blah blah ... Our bills are due for immediate payment'
New property? Change of address? Could they really not have got their act together before now? 
Now I'm supposed to rustle up £750 just like that.
Is it worth my complaining to Ofwat or anything? I think it's really crap that they haven't been in touch with me before now (and I'm going to struggle to find that kind of cash too)
