For GCSE chemistry is knowledge of how the periodic table was developed actually needed as I have yet to come across a question where it is needed and whilst I'm happy to revise it, I obviously don't want to waste time if it's unnecessary?

Yes, the knowledge of how it works is very important. You are given a copy of the table in your exam, so you don’t need to memorise the order of the elements, however you do need to know how it works, the periods and groups, reactivity of the groups as well as the development of the table (Dobereiner, Newlands and Mendeleev)
