MN1 Applicant Address Proof

[DEEPAM]

Hi
we recently (26.05.2017) made an MN1 application for my LO (10 months old) , we are moving to a different address by end of this month. I haven't received any acknowledgement from UKVI yet . Shall i inform them about the address change now ? or wait until i receive an acknowledgement letter so that i can have a reference number to quote while sending the details about address change. I haven't had any address proof to show for my little one instead of that once we receive the new tenancy agreement ( which quotes my name and my husbands) , can i use it instead for address proof ?
could any one help me to send the details where i can send a letter about address change or online submission is the only option?
Thanks
Deepam

I suggest u wait for the acknowledgement letter or email which will have a Case ID or reference number and then contact them on https://visa-address-update.service.gov.uk
