The UK has a concept of a BritRail pass for people from outside the UK. It's currently £568 for a month long pass.
That would be £6816 for a year, although (again) "You can use a BritRail Pass if you’re not a UK citizen and have not lived in the UK for the last six months or more.". I guess you'd have to go home before the end of the 6th consecutive month of using the passes otherwise you'd disqualify yourself.

The All-Line-Rover would be the version for anyone who does live in the UK: http://www.railrover.org/pages/all-line.html and it is much more expensive.
