I'm looking to find some books to help me out. A few topics I'd like too improve on are 'being a better design leader' how to be more organised running an agency' and other leadership / management / self improvement books for designers?

Maybe this isn't exactly what you're looking for, but MIT Press has a curated list of books on Design Thinking (https://mitpress.mit.edu/books/series/design-thinking-design-theory)
One of the books (Frame Innovation) is authored by one of my former professors, Kees Dorst, on how to approach solving complex and highly networked problems; I highly recommend it :)
