I build a relationship with a few recruiters in the US, and I specifically told them that I don't want to waste their time and to start off with a compensation package any time they have something interesting. I cannot even comprehend discussing a job without salary range.

Ive lived in the top two tech city in EU (edit: Europe as of now) London and Berlin and there were always ranges in job specs, now I'm in Amsterdam and it's the only city that doesn't seem to like that (along with coding turning on the brain, i would say)

A few days ago I was contacted by a British company for a remote job, no salary disclosed. I heard that in UK it is disclosed, but I cannot confirm.

It varies a lot in the UK. Some companies share ranges in the job description, most dont. Many don't share a range publicly but you can get it in the first call with the recruiter if you ask. Some just don't give you anything. And the worst are the ones that don't give their ranges but ask for current and/or expected salary.
