Climate also plays into this. I live in the pacific northwest, and I need to drink VERY little liquid go stay hydrated - there are plenty of days where I drink less than 1L and feel fine. But when i go anywhere dryer - e.g. southern california - I’m constantly dehydrated. England is pretty humid most of the year, a lot like the PNW.

I'm going to assume you live west of the Cascades... east of the Cascades I drink like a fish because the air is so dry.
