They seem to be a reseller of eukhost.com. Both their servers come from bluesquare datacenter in maidenhead. Although it could be the other way around. Any way to tell?
I used them for a month before switching to Heart - not because they were bad but because I have a lot of sites and we were going to migrate to Heart anyway, and yeah I think they're just a reseller.
One thing I can say for them is tremendous support - answered my queries almost immediately any time of the day or night.
I have some sites with Webhosting.uk.com and echo what Phil said regarding support, very good, not only by email but also they are on msn and have a forum too.
Uptime is pretty good too, currently a lot better than another of my hosts.
