Sadly not, as much as I'd love to see another free-roam game take place in my homeland... Fallout is an American series. The whole charm in fallout is how it makes fun of the whole 1960s-70s cold war propaganda and how the world was at that time. I don't think that charm would work in the U.K as we never (officially) entered the cold war and I'm doubting they'd be all that much to make fun off when it comes to nukes.
