Naturalised, waiting for a passport, what admin changes do I have to do?

So yeah, the long journey is over, many thanks to everyone here, as I have spent hours reading up on this and getting ready.

I have had my ceremony and received my certificate, and I have applied for my first British passport. Once I have it, whom do I all have to update regarding this? Presumably the banks will want to know. Voter's register as well, I'm already on the electoral roll, but as an EU citizen, so I guess I have to update it now to be on it with full voting rights?

Do utilities need to know? Credit reference agencies? Anything else I might be missing?

Thanks in advance for this final question of mine!

Yes - change nationality to British

Do utilities need to know?No Credit reference agencies? NoAnything else I might be missing? In most areas of everyday life nationality doesn't really figure - unless I have missed something.

Inform your employer, if applicable, with copy of passport.

I agree. Within the UK, acquisition of nationality is not as important as acquiring settled status (whether ILR/PR/EU Settled Status). Very little if anything of day-to-day life is impacted by the acquisition of British nationality. It does impact voting rights, but only if you are a non-Commonwealth citizen. And indeed Wales has extended voting rights in Welsh Parliament elections to everybody with settled status (all three types listed above).

As @vinny has pointed out in the past, what is so special about British citizenship?
