If you hold a Biometric Residence Permit (BRP) because your leave has expired, or you were issued with a replacement you must now return it to the Home Office as it no longer valid. You should cut the card in half and post it in a plain, windowless envelope. If you are returning the BRP from within the UK then please send it to: BRP Returns, P.O. Box 195, Bristol, BS20 1BT. If you are returning the BRP from outside of the UK please send it to: BRP Returns, Home Office, Conference House, Conference Avenue, Portishead Office Park, Portishead, Bristol. BS20 7LZ. You may be subject to a financial penalty of up to £1,000 if you fail to return your old BRP.
