Any advice would be very appreciated

If you already have more or less of a grasp on spoken German, I'd say it's time for the grammar book/website and some easier pieces of reading...such as graded readers (Easy Readers) or parallel texts. These you can find in the UK very easily. German word order is complex and it's best learned by reading up a little on the rules...and then lots and lots and lots of examples.
If you have problems reading, then there is only 1 solution: read more! It's the learning by doing principal. The more you expose yourself to the written language, the easier it will become.
