Basically it can be organised between you, while you are in the UK and your gf is in the Philippines. And then you will need to set aside a few weeks vacation time over there to get married. It can be done in about 2 to 2.5 weeks but can be done more comfortably in 3 or 4 weeks. I spent 2.5 weeks over there when I got married. But you need to get all your ducks lined up in a row before you go.
