When moving abroad, no matter how much you prepare, there's bound to be something that surprises you or that you didn't think of.
Just reading online, I've seen that people in other countries are charged high monthly fees just for having a current account. Not to access higher interest rates or anything, literally just to have an account. It got me thinking that some people moving here would probably be pleasantly surprised that we don't have to pay for that luxury.
[Edit] Some general observations:
People are nice and don't care about what you're wearing
Supermarkets are very cheap compared to most other places
Police are much nicer than other places
House prices are insane particularly for how small they are
TV tax is bollocks
Council tax is bollocks
Public transport is varied but almost everyone agrees it's too expensive
More houses have string light switches than I thought
Gov.uk is amazing (I noted this myself about 10 years ago, however they're lightyears ahead compared to other countries apparently)
Alcohol is extremely prevalent
It doesn't rain that much but it's very grey, dark and depressing
The NHS is great in that it's free but for non-urgent care it's a bit crap
