You must report any changes if you’re in the UK and have either: got a biometric residence permit (BRP) applied for a BRP but haven’t had a decision yet How you do this depends on what you’re reporting.
You can change your address without having to apply for a new BRP.
Which form you fill in depends on whether you:
have a valid BRP
have applied but haven’t had a decision letter
You must report all other changes to your circumstances. How you do this depends on what’s changed.
You must apply for a new BRP straight away if any of these things change:
name, for example, if you’ve got married
date of birth, for example, if it was wrong
How you report the change and apply for a new BRP depends on whether you have:
permission to stay in the UK temporarily (‘leave to remain’)
permission to settle in the UK (‘indefinite leave to remain’)
You must report any other changes to the details you gave in your BRP application, including if:
you get a criminal conviction
you separate from your partner
any of your children stop living permanently with you
