Yeah, this is such a relevant question for me as I am not British and I am constantly learning about all kinds of British companies that I have not heard of before such as GAIL’s Bakery. I think one tip is to just focus on one industry at a time and slowly build your awareness based on that like retail. I also think just observing shops on the street while commuting to the office or school (which is what I do) and then googling about them is also helpful.
