Awaiting ILR Application - Changing Address

[ILR-1982]

Dear Sir/Madam,

I have submitted my application of indefinite leave to remain under Tier 2 Dependant route in October 2020. This application is attached with my 2 children (5 years old and 7 years old respectively) as well. So far, I haven't received a decision from home office yet but I moved to a new address few days ago. I understand that I need to inform home office regarding the change with the address proof. My question is as below:

1. So far I only have water bill which includes me and my husband name. Would this be sufficient?

2. For my 2 children, they are still living with us but they have no formal address proof. What can I do with this?

Your advice is very much appreciated.
Thank you.

1&2) there is no proof of address needed for changing the address. Ideally maintain the good relation with the residents at old address because UKVI still sends the documents at old address despite you can update it at below:
