Dear Sir/Madam,

I have already contacted you about this change but have received no acknowledgement.  Please will you note that Mrs Janet Hudson is responsible for this account as from 6th July 2015 (the date of the last bill reading).  All future bills should be addressed to her at 2 Repton Close, Gosport, PO12 2RY 
Southern Water have also been informed of this change and they have acknowledged the change in their records.
With thanks.
