Dual Citizen Inquiry

[Casserole]

I am a Canadian/British citizen (born in Canada, British by decent) and I hold valid up to date passports for BOTH countries. I am moving to Edinburgh in September 2022 to attend college fulltime. I already have a permanent place to live arranged. I am planning on remaining permanently after graduation. I have never lived in the UK before. I am hoping for advice on applying for a NINo, how to register with the NHS, how to transfer my driver license, and how my taxes will work. Anything else I should be aware of before or after arriving?

Advice or direction would be much appreciated.

Thanks!
