Plusnet contract

[#1]

If you have a 12 month contract with PN for home phone and broadband what happens when the contract ends ?
Are you notified or do you get transferred on to some higher standard rate.
I ask because prior to transferring to PN I was with BT on a 12 month phone contract which cost £18 a month (anytime call package) but when the contract was finished I was transferred or defaulted to the standard tariff without notice so the phone bill for that first month was quite high due to calls being charged at normal rate.

Unless your 12 month contract has some special reduction for the whole 12 months it won't make any difference to the price.
If there is a discount for the whole 12 months then you would move to the standard rate at the end and go onto a 10 day notice contract
