I am reading this thread eagerly, as I came visitng with the exact same question. I have been with UK2.net for several years now and really need to change badly, they are ........... ! I wish I had changed earlier. I now need to transfer 25 domains because I am so sick and tired of their bad customer service and 'attitude'.
I have currently been trying to find out why 'Webdiversion' has stopped working on one of my domains, a simple task you might think, but I have been trying since the 15th of this month. It is not possible to contact them by anything other than e-mail, they never sign their names, their answers to client enquiries are blunt and often plain rude. Most of my mailed queries about the current loss of my webdiversion have been ignored.
When I first sent the query I had a one line reply which told me that my domain was not with them and so they could not help...... This was despite my domain being on my list of domains, on their nameserver, and if you did a search on it, it came up as "A UK2 domain", I transferred it in to them in 2003 and had the documentation.
Being rather puzzled by this response, I pointed out all of this to them; I was then informed that they had 'lost' my domain....... or it had been 'stolen', for the second time in two years, simply because they had not locked it despite it being a .com domain. I could go on and on, but it's too tedious.
They are utterly dreadful and I would not recommend them to anyone, they are cheap, but I guess this is a good example of the old adage that you get what you pay for.
Avoid UK2.net !
