Hi everyone,

I just attended my citizenship ceremony today and am about to apply for my British passport. I was wondering where I need to update my nationality information now that I’m officially a British citizen.

Any advice or a checklist of places to update would be greatly appreciated!

Thanks in advance!

As such there's no requirement to do anything ... as you know the UK doesn't have a register of citizens (and no ID cards!).
However from a practical point of view, first thing should be to register to vote, if you haven't already, make sure nationality is shown as British. Contact your local council or google "Register to Vote"
Tell your employer so they don't keep chasing for right of work proof.
Tell your bank you're British, you may be able to update your online banking profile.
That's about it. Otherwise, only needed if you are asked.

I've personally notified my insurance provider and mortgage provider, my bank and my employer. Government agencies such as HMRC and DVLA don't need to know.

Big thanks both of you!

If you are renting, you would need to also notify your landlord and show your British passport/naturalisation certificate.
