Options in event of loss of ILR approval letter

[nwojibs]

I have lost the approval letter given to me at the PEO.

Form AN requires applicants to send either of the following as supporting documents for Evidence of freedom from immigration time restrictions;

Passport showing permission to remain permanently in the UK.

The Home Office letter by which you were given permission to remain permanently in the UK.

There are two letters, with wording, that convey notification of permission to remain permanently in the UK.

The letter issued at the PEO on the day of the application for Indefinite Leave to Remain.
The Biometric Notification letter that accompanied the Biometric Residence Permit.

In event of the loss of the letter issued at the PEO, can the Biometric Notification letter with which the Biometric Residence Permit was delivered as well as the Biometric Residence Permit itself be acceptable as evidence of freedom from time restrictions?

I would appreciate if you can advise what options are available to me.

Correct! the BRP card alone should do the trick, the letter is optional, don't worry about not having the letter.
