I am with the Utility W*rehous* and after a very bad start with mad billing It is now ok £32.5 per month with 512,free calls anytime and line rental included.
but I had a job to get the billing, right signed on the doorstep job was supposed to be £29.22 but its never been that..chap with a mobile phone.hmmm. I would not recomend them now or ever. I dont think they do the same package at this moment. They also have a £200 or so get out clause, not mentioned, if you move before the year contract, no migrating. Although you can nearly always get through to speak to somone they had a big billing problem which has now been resolved also my broadband was not enabled for 3 months they blamed bt. But I still paid for it with no refund.
