Change of Circumstances

Hello, I am writing this for a friend they need some guidance on this. They have applied for their permanent residency under Tier -1 (Entrepreneur) visa. They applied through the new online system and all the paperwork has been submitted and their case is now under process since the last 4 months. However, this month they have changed their company address to a new one and the new address has also been updated at the company house. The question is that they have not informed Home Office of this change, do they need to? Can it cause issues for their case if they don't write an update to HO for the new change of address of the company? All their personal details (Address, email, telephone etc) remain the same.

Looking forward to some guidance on this! Thank you.
