I've been with Zen now for almost three years and its been the most trouble-free three years of my fourteen years on the internet. In that time I've been with Pipex, when they were good, with Btbroadband when they were the first to go the way of the all in monthly payment (I got fed up of having extortionate phone bills) and finally came to Zen, when I decided to look for a more reliable, un-throttled service.
I really can't praise them highly enough. The transfer over to them was trouble free, despite BT 'losing' my transfer order. I can't remember when I last had any downtime on the connection (I suppose I had better touch wood here), and that downtime was only for 5 or 10 minutes.
They are more expensive than the run of the mill ISP's, but you really do get what you pay for with them.
If you have to phone the help desk for any reason then you are made to feel as if you are speaking to a human being, not some automaton who has to go through a pre-written list of things to try before actually getting down to help you sort out your specific problem.
Another good thing is that Zen don't out source for the call-centre. Its a local call and you speak to people who you can actually understand.
Sorry its a long review, but like I said at the beginning, I really can't praise them highly enough.
