Hi there,
It's always a case of 10 days' notice for our accounts, unless you're on Fibre though I take your point about the other deferred contracts on there (hardware and setup etc).
Having checked your account you'd have to pay the deferred setup fee of £25. There'd also be the £25 cessation fee if you were moving to cable or actually cancelling the service rather than migrating it. There's no deferred hardware charge though.
Hope that helps.
