Spouse visa extension coming up - proof of address

Hi all, my wife have a spouse visa extension coming up shortly. We need documents that date 2 years back from when we apply to extend right?

We have joint proof of address on 1 council tax bill that is from March and water bills that we have together from 2023 onwards.

Do I understand correctly that we will need 4 other documents each from at least 2 sources that are dated in the same months? Does V5 count for this?

Other than that we will have bank statements available for any dates, and for me something like broadband bill and wife probably has some hmrc reminders.

Just wanted to check that I understand it correctly and have whats needed. Thanks!
