I was also with BeThere and was very reluctant to leave. Their service has always been excellent. Unfortunately, although we had FTTC in our road, when I approached Be I was told that they would not be selling FTTC until at least 2013.
At the time I was working on contract with a company who had been using Claranet successfully for many years and were having to move to another supplier as they could not provide the additional security they required.
I was most impressed with my initial contact. I was not called back by a sales person, but one of the support guys, who answered all my questions readily. On the basis of that conversation, I signed up for a 80/20 Business SOHO package.
We've been with them now for a little over 2 months. Initially the service was not as fast as the old ADSL2 line we'd had before, that gave us 15Mbps. However, after that things have improved to the point of getting to 40Mbps. I phoned them on Thursday to point this out and today I hit 60Mbps. There does, however, seem to be a slowdown when the Olympics get exciting. (Is anyone else getting this problem). Just done another speed test whilst writing this and it's down to 43Mbps. However, Claranet are doing further tests and are due to report back with results on Tuesday.
All in all, Claranet's support is first class. No Bulgarian accents, just Manchester and Liverpool ones.
One thing I have noticed is not only the speed increase, but also a big jump in reliability. Even when hard hit by the Olympics and noticing speed drops, the service is not unusable, which at times ADSL2 was.
I might add that I am, what most suppliers would consider, a heavy user. My blog tells you how heavy

. No limits on this service and no apparent traffic shaping.
