Tier 1 general spouse visa after her 5 years completion

hi,
I want help with what sort of visa do i apply. as there is so much of confusion on internet.
my wife she came to UK in oct 2013 as my dependent at that time i was on Tier 1 general (hsmp visa).
now i got naturalised and i am british citizen . my wife already had her second extension as Tier 1 general dependant .
after 5 years which is in oct 2018 it will be 5 years for her in uk and she has not been out of country more than 60 days in continuation for holidays.
she has done her life in uk and english test.

my question is ?
what application or visa should i apply for her to get settlement or ilr . is it set(o) or something .

please help thank you

On what basis did you get ILR?? 5 years Tier 1 General or 10 years long residence??

its on 5 year basis.

and please let me know about the maintenance fund as well

What date was her initial visa valid from in 2013??

oct 2013 . she is on pbs dependent leave to remain.

What is the EXACT date of her visa start date and the EXACT date that she entered the UK??

visa exact start date is :- 19.09.2013 valid till 29.04.2016
then i had her extension done in 13.04.2016 as pbs dependent which is the current one expiring on 13.04.2019

she came to uk :- 22.10.2013

She can apply for ILR within 28 days before 29 September 2018.

She must use form Set(O).

There is NO maintenance fund requirement for ILR.

I will now move this topic to the ILR sub forum.

Thank you very much for patiently responding .

appreciate your help..
