Oh my...I'm sorry Belinda. Looks like the form doesn't cover the change of name.

On this page, https://www.gov.uk/change-circumstances-visa-brp/youre-in-the-uk-and-have-a-brp, it states below:

Report all other changes

You must immediately report any changes to your:

  • name (eg because you’ve got married)
  • gender
  • nationality
  • facial appearance
  • date of birth (eg because it was incorrect)


You must apply for a new BRP within 3 months. You may be fined up to £1,000 or have your stay shortened if you don’t.

You should use form NTL or TOC to report these changes and apply for a new BRP.
But I checked that NTL form and it's for ILR holders. TOC is for transfer of visa. I'm now confused! When I replaced my BRP, I used the BRP(RC) form but it has the section to change the name.

I think you better call UKVI for a clarification.
