Thanks for all the help guys...and please dont take this is as a rebuttal, i just thought it might help anyone in the same position. I lodged the query with the embassy and they replied:

"Your UK-issued CNI is valid for 12 months from the time it was issued. Yes, you we will accept it. No need for apostilled.

Yes, we would also require you to submit a CENOMAR, reason is we would also like to know if you have never been married here in the Philippines. Maybe your fiancée can help you request from the NSO (National Statistics Office) here in the Philippines."

So looks like they've eased the 3-month rule...wait, something made easier? hehe, that cant be right!

regards...
