Use different mailing address and residential address

Hi, I just moved out of the UK and am filing my SA100 and SA109 by paper forms as required. The country I live in now has a very unreliable postal service, so I am afraid that if I use my current residential address on the form then any reply from HMRC might not reach me. Is it possible for me to use a UK mailing address (e.g., a friend's address) on my tax returns so that any replies from HMRC are sent to the address in the UK and not to the foreign country where I now live? Thank you,

Hi lkj7438,
You can, when you do this include a covering letter explaining that you wish to use the address for correspondence and the reason.
Thank you.
