I realise that I can't enforce this with a validation rule, so was thinking along the lines of creating another field, making it unique, and updating it with the values of two fields combined, but that probably won't work either.
Any ideas on how I can prevent this happening?

Hi Glenn,
I don't know how complicated it is to accomplish this using duplicate rule/validation rule but I can suggest you to get advantage of a trigger/flow. I can help you in trigger but you will have to wait for someone who is more efficient in flows.
Thanks,
Naval
