Thank you for replying, I'll make sure to send of a council tax letter to them.

I hope this is the right place to ask this question because it is quite complicated. Last year I received a water bill from anglian water for a buy to let property I use to own, the bill was actually dated 2013 but the property was apparently sold by the mortgage company in 2010, I say apparently because their was no formal repossession and i was never signed anything they just gave control to an lpa receiver who managed it badly and it was then sold. I would like to know if anyone knows how anglian water go about getting information on properties and why they haven't got the new owners information. I have emailed anglian water but they take 10 working days to get back to you.
