There are some misunderstandings in this thread that I think need to be cleared up.
Firstly, a number (possibly including me) have mentioned about migrations and the rules that migrations cannot be blocked. However, you aren't doing a migration - a migration is from one ISP to another not moving house and therefore the rules around migrations aren't relevant.
The second thing is Vivaciti don't actually do a home move service/product. What they are actually doing is cancelling your contract at the old address and starting a brand new contract at the new address. Any terms of the old contract become irrelevant and they have put you on their current product at the new address. The current product includes 12 month contract term.
So, with all of that clear and the new information since I last posted I think you have a strong case for them misleading you. They didn't tell you about charges (except for a very wobbly £8 figure). They didn't explain you were cancelling the old contract. They didn't explain you were entering into a new 12 month term contract with all new Ts&Cs.
Unless there are other communications we haven't seen Vivaciti have very poorly communicated with you and have given you incorrect expectations (especially around the charges). It is possible they were answering the question that was asked but when starting a new contract with someone they should be very clear on the terms of that contract - in this case it seems they haven't been.
EDIT : Just to add, based on this thread you look to have a strong case to take them to ADR/court. Unless Vivaciti can show where they gave you the above info then I don't believe they have a leg to stand on - very poor communication.
