You sent us a letter reference number 71838222, our last address was not in our name it was in my mother in laws name and she did not move with us to the above address.  She remarried and is now living at a different address.  
We moved into the house on 2nd July 2015 but completed on the house 20th April...we have not been living there for 3 months because of decorating so the house was unoccupied for this time apart from being over there after work to paint.
We now have tenants in our previous home which is 78 Valentine Close, Fareham, Hampshire, PO15 6SL.  It is up to them to sort out their own water bills.
please call me if there is confusion.
Regards
Diane Downey
