Well, East London is heavily populated by Muslims, Mosques are around every corner (East London Mosque is about 10-15 mins walk), Halal food is easily available and there are plenty of muslims to get along with.
Brother iqram, just wanted to say may Allah make your hifz exam easy for you and inhsallah if ur already not allow you to teach the wisdom of quran and its beuatiful words to others.
