Was living in UK too and I promised myself - not to miss a single sunny day. So I went out every day and at least every weekend spend at beach. For acne ask your mum for advice. There is plenty of skincare products so you should exfoliate few times a week. But basics is - sun, fresh air, healty food, lots of water, and sweat. Sweat is the best cause it pushes out that dirt making cells to breathe. If you look in your armpits - theres acne too but it looks clean cause you sweating all the time. Also I noticed that supplementing with whey protein(myprotein.co.uk since you training it could benefit you even more. Whey and and glutamine is all you need{one serving after excersise} better spend your pocked money there rather then sweets which will make acne worse) helps skin look better cause skin needs protein too - it consists of it. It will take months to get rid of acne but its possible - just do whats best for you.
