I've lived all over the UK. I think Cardiff was the hardest to "slot into" - an English accent in Wales can prompt some interesting interactions ;) Though small-town England is also a nightmare of "if you didn't grow up here, fuck off".
Social class in the UK is all about where you were educated, it has nothing to do with your income (same for Australia, but apparently not the USA, though I think that's changing). Your accent, your manners, whether you call it "dinner" or "tea", whether you go to the toilet, the lavatory or the bathroom. If you actually care about social class, these are the things that matter. Income doesn't.
But attitude is the big one. You can fit in and make friends anywhere with an open attitude. People are people. Friendships can easily overcome class and income differences if there's mutual respect, empathy, and a desire to be friends.
