Top UK webhosting companies for wordpress

Recently I’ve been doing some research across various reviews on the net to find the best UK companies that offer suitable webhosting for wordpress.
 My client has been using 123-reg.co.uk for the past few months, and found his site to be extremely slow to load, and sometimes didn’t load at all resulting in a timeout error.

Here’s the final list:

• http://www.uk2.net/web-hosting/
• http://www.clook.co.uk/services/shared-hosting-uk/
• http://www.tsohost.co.uk/hosting.php
• http://www.evohosting.co.uk/hosting/starter
• http://www.webhosting.uk.com/cpanel-hosting.php
• http://www.uk-cheapest.co.uk/hosting.php

which would you choose?

Update: Went with tsohost.co.uk in the end, very happy so far with their hosting package…
