There may be some but it may be more expensive as you may have to pay higher one off charges. The longer contract tend to recover some of the costs over the 18 month contract

I would steer clear of IDNET. Contrary to what you will hear in these forums, their support absolutely sucks. They just make it up as they go along, and crawl along at a snails pace.

If you are lucky enough to get a good provision, with no need for support - you'll be OK. But I've had three provisions from them, and each one has been screwed up. They always blame BT, but it doesn't seem to happen to anyone else quite as often.

Consider trying zen.co.uk instead. They actually know their stuff.
