When you apply for ILR, you will need to enrol biometrics as part of the application. This will be the case even if you might have enrolled biometrics for a previous visa and even if you have previously been issued with a Biometric Residence Permit (BRP).
When your ILR application is approved, you will be issued with a new BRP.
Your BRP showing ILR status will normally be issued for 10 years.
When your BRP expires (unless you have subsequently left the UK for more than 2 years or been granted British Citizenship) you will be required to renew the card.
You will need to check your BRP card carefully on receipt. If the card bears any errors expiry date you should follow up on this with the Home Office.
Due to changes in Encryption Technology your new BRP may be issued automatically with an expiry of 31 December 2024. This will not affect your status and the Home Office will keep BRP holders up to date as to how to update their early-expiring cards.
