Ross,
As the sponsor of the original Fiance visa, I included my bank statements & pay slips, to show that our original financial circumstances hadn't significantly changed during the two years.
(so, various bank statements & pay slips thru-out the 2 yrs, with the last 3mnths fully documented).
.... Please note, although I'm not aware of any Filipina's having their ILR refused due to a change in financial circumstances.... it has happened with others.
In your case, your bank statements should be spread over the 2 yrs, as proof that you've resided at that address, and the account is being used and "serviced" regularly.
