Hello, I am looking to be moving house in just over 12 months and was thinking about changing my product from the Fibre Extra 250gb package to the new fibre unlimited package. I am aware that when the product changes, the contract starts again and is for 18 months. Could you let me know what would happen if I were to move house inside of my 18 month contract? As above its likely to be early 2014 when I do move. Thank you.
