Transferring to another Biomed course at another uni

So I’m a first year biomed student at Anglia Ruskin uni, I’ve been getting decent grades but hoping to improve them during the second semester as I was hoping to transfer to another university in london as my family lives here. I moved from London to Cambridge at the start of the academic year but I moved back because Cambridge was too small and other than the education there was nothing to do. Jobs were also very limited and horrible pay. I am not going into my second semester, but I’m commuting from London and I don’t drive which will be too expensive for me. And even if I drive, my uni doesn’t have any parking. I wish I could start my second trimester (which is next week) at a london university as my situation is an emergency, but if not, was hoping to continue to the second year of my course here in london.
I was unable to do anything as the were closed for weeks due to Christmas and new year which slowed the process down for me. Does anyone know much about these kind of things, I’m struggling on where to start and how the process will be. Really stuck rn , I know KCL and imperial college london and other universities allow students into their Second year of biomed but the grades but the college and GCSE grades would have had to be high and mine weren’t (I got ppp (pass) in everything). This of course puts me down a little bit but I’m doing the best I can and would really appreciate some help.
