Agencies & authorities I informed after gaining UK citizenship

Hello Reddit,

I saw this question has been asked a few times, so I wish to share my personal experience on which agencies and authorities to inform after I gained UK citizenship earlier this year, hope it helps you:

(1) I registered to vote and my local council processed my request and put me on the electorate;

(2) I applied for my UK passport and also sent back my ILR BRP card to HO immediately after my citizenship ceremony, even though my BRP card already expired on 31/12/2024.

(3) I called HMRC and they updated my nationality on their system and told me it would not affect my tax account/status;

(4) I called DVLA and they said my driving license does not need to be updated/renewed as it only shows place of birth, not nationality;

(5) I called Home Office about my existing ILR e-visa, and they told me I do not need to do anything and my e-visa will stay as it is. I can still view my ILR status and even generate share code of it. But HO also told me once I get my British Passport, I should not use my e-visa (e.g., for travel or prove right to work).

(6) I called my banks/mortgage lender and asked them to update my nationality information, as I opened these accounts using my foreign passport before. They updated it on their system and told me it would not affect my accounts/mortgage with them.

(7) I called my GP and they asked me to bring my UK passport to them and get my nationality updated on NHS system. They also told me it won't affect my access to NHS services.

(8) I also informed my employer and they updated my citizenship information to show proof of my right to work.

The above things are what I did so far after my naturalization. There might be other agencies that I need to inform, and I would continue to update my nationality information if/when asked.

Regarding my insurance companies, they did not ask for my nationality when I took out their policies, so I guess it is not required to inform them the change of my citizenship.

Any questions, please let me know, I am happy to discuss.
