Bargain bin ISP for bargain bin people. Considering how many ISP's offer new customer discount's and when a price rise comes you can migrate away to another ISP on a new deal if you are that worried about price rises.
in terms of internet pricing there was times when 3Mbit broadband used to cost >£50 alone.
Plusnet have been ok for me most of the time, I had a couple of problems, but they was not Plusnet fault, it was a BTOR network problem and to be honest Plusnet got BTOR out to look at it a few times to solve the problem, i am still not sure if the problem is really solved, but it seems ok at the moment. plusnet even sent me a different router, a Zyxel instead of their normal router to see if that would solve the problem and it seems to have done so.
Speed wise I get more than neighbours who are on the same cabinet with different providers, next door is with BT and they are getting 24Mb/s if they are lucky, I am getting 38Mb/s and paying a lot less than they are.
Price rises are not nice and I admit I do not want to pay more, I have not had any email to say my package is rising in price. but yes, when I first started to use broadband in 2000, ADSL was 512Kb/s and cost me £39.99, plus line rental on top.
Plusnet is not perfect and I know it is still owned by BT, but it seems to be run as a separate company and certainly do not have a BT feel to it. they also leave me alone apart from the odd email about their sport app. Not like BT, sky or Talk Talk who seems to keep on pestering their customers to get more added on.
