Who delivers Biometric invitation Letter?

[mantasingh]

I want to know is it Royal Mail or DX Secure who delivers Biometric invitation letter.

Reason: I filed on 26th March and it seems that people who sent application later than me got Invitation letters last week.

I reside in an apartment which is part of building with secured entry points.

Royal Mail delivers but not sure whether DX secure has got the access.
So just checking who delivers and is there any issue with DX secure getting into secured buildings.

Royal Mail deliver the biometric invite by second class post. No signature is required, so you should receive this with any other mail you get.

DX Secure is a courier and they deliver the actual BRP card once your application is approved. This requires a signature with proof of the applicant's ID.
