How Home office returns application documents?

Hi,

I am going to send my tier-1 extension application.

Do I need to provide an envelope as it was before or arrange collection by a DHL?

What is the best way? thanks

when i had applied i had sent self addressed next day delivery envelope as well along with application form. i got my passport and other supporting documentation through that envelope. ukba uses DX secure courier service for biometeric card.
