Fortunately, there are still some good ISPs left in the UK. I'm with Andrews & Arnold and they're staunch supporters of an uncensored net (http://www.aa.net.uk/kb-broadband-realinternet.html). They're also just generally awesome - dual homed static IPv4 and IPv6 addressing, a geek answers the phone if you ever have reason to call, you can choose your backhaul transit provider and lots of other nice things. You can even opt for billing that follows the lunar cycle :)

Regardless of ISP though, I think even Joe User should figure out how to install & use a managed VPN service for when they're out and about using random wifi networks (e.g. from privateinternetaccess.com or similar). Of course, that assumes these VPN services are trustworthy which I'm sure a lot aren't...
