There are 2 options for your husband to send his passports, either via VFS to London, or via xpresspost/courier to CPC-O.
under information chart the box for name and addresses are for return labels, according to me if he is applying via VFS, no matter
whatever address he writes because eventually he will have to pick up passport from VFS office.
if he is applying via xpresspost/courier to CPC-O he should write his name, address, phones (email: same as of application)
double check from seniors please..
