British Citizenship Supporting Documents

Hello

I am a Norwegian National living in UK since 2005. My wife (Pakistani National) came to the UK on EEA family permit in 2013 and now she has settled status for more then one year. During her stay in the UK I have been continuously working exercising treaty rights.

I am going to apply for British citizenship for my wife but I don't what documents I should provide for the following (My wife is a Home maker. she has no employment record in the UK):-

Evidence that you have been in the UK lawfully for your 3 or 5 year qualifying residence period. This should be evidence that you were here as a worker, student, self-employed, self-sufficient, retired or incapacitated person

Many thanks for your help

Consider official type documents such as:
Council tax bills with wife's name included, Child Benefit notifications, Pensions P60 (if in payment), other official notifications (HMRC, DWP, other government departments?

Thanks for your reply!
