I've been with Plusenet for about 18 months and have had an excellent service throughout. Initially a very fast new connection was setup (within 5 days of signup) and consistent speeds of around 5 to 5.5mbps and I'm in a small village and so no one can get much more than than unless they live next door to the phone exchange and then they get 6mbps!
The service is reliable and I can only remember one evening in the last 18 months where there was an outage of a couple of hours due to BT infrastucture fault.
Customer service on the 2 occasions I've called have answered quickly and helpfully and in the UK so you can hear them as they clearly use half decent phones unlike all other call centres outside the UK.
The have referrals too and I recently got 3 months free internet for signing up a family member which was a welcome surprise!
I hope nothing changes as I hate having to change ISP's.
