I sort of doubt your freshers experience. It has already been confirmed in my uni that first semester will be online based, so I’m thinking that anything involving large gatherings (lectures, freshers fair, societies) will be cancelled, at least in the beginning.
That being said, considering everything miraculously clears up by then, you won’t have an issue. I can’t speak for all Uni’s, but my university (which is a London Russel group uni) has LOTS of Muslims, just from my observations more than people of any other religion. If you’re worried about not fitting in, that should be the least of your concerns.
I didn’t commute, but I didn’t live with with other students either so it was pretty much the equivalent. I didn’t have any trouble making friends in the first few weeks. Yes, people will likely make friends with their flatmates but at that stage, they’re open to making friends with absolutely anyone else too. I literally sat next to complete strangers in lectures and asked what course they were doing etc and it went from there. The people who I arranged to go clubbing with were all people from my course. You’d also be surprised just how many people commute, especially in a London uni where accommodation is very limited. I would say that in the first few weeks, the number of people who I met by chance who commuted far outweighed the number of people who lived on campus. In fact, I think I only met like 3 people initially who lived in accommodation.
Not sure about kings but there are always going to be plenty of places to chill around any uni. If not, don’t forget you’re in the capital city, you have endless options. Hit up a cafe, or something?
