Which UK hosts do people recommend?

In theory, it should be easy to run a poll here and work out who's good and who's not good. Probably in three bands:

1 budget
2 mid-range
3 pro

I'm personally interested in (1), but only if they're using reliable, OK servers. My criteria are:

5gb space
10/unlimited databases
5gb bandwidth
PHP, CGI, file locking enabled, standard php permisisions
email, phpmyadmin, etc....
