I just called them up and asked. I'm out of contract also so they probably wanted to keep me. I'm more than happy with my service from Plusnet, so a 18 month contract doesn't both me. There are a few that do broadband only (where you can have a phone line somebody else), but most of them seem more expensive than Plusnet.
Some smaller providers will do broadband only but as you said they are more expensive. i still have till August until my contract is out, I am not sure if I will move either. I will have a look and see if my old ISP have sorted things out and I may go back to them. i still have their equipment on my roof, so at least they will not have to charge me installation fees.
The only problem is could I go back to 10Mb/s?
