Assalamualaikum dan Salam Sejahtera,
At this time around, especially those who are coming to the UK might already found your accommodation through agents or the university. But for those who are still looking & want to stay in private accommodation, you can try searching in facebook groups for freshies for the new term. If you don't find any adverts you can always advertise yourself looking for rooms/house to let. I'm sure there should be plenty out there. Good luck in your search. May you find a good home. Some suggestions to look out (for Manchester) as people are coming & leaving at this time:-
Sekian, selamat berpuasa!
