Fibre Unlimited upgrade question - possibly moving house within 18 months??

[#1]

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.

The way it normally works with ISPs is that moving home triggers a new contract. You may also be a charged a connection fee for installation at your new house.

I think the Home and Office Move Guide covers most of your questions. In a nutshell, assuming your new home has FTTC available you would continue on the same product but a new contract would be started.

If you cancel then you'd be charged £5.75 a month for the remaining contract term plus any cancellation fees etc. as stated here

I wouldn't neccessessarily cancel, I would either carry on using Fibre FTTC or standard ADSL2 package from plus.net.
Cheers
