Check out http://www.hostingdepartment.net or their U.K sister site http://www.ukeasily.co.uk/ .

I'd suggest you to check with support and chat, find how forthcoming a host is with respect to your queries and if they truely are, you'll enjoy hosting with them. Going through testimonials alone wouldn't help much.

I have used Hsting Department.net myself, so i can say it is pretty much reliable and fast. php5 is also available with them.
