It is actually easier to get her here on a Fiancee visa from Dubai, than it is from the Philippine, although with UKVACS it is much better, but you never know how long it will last.
You just need to download the Fiancee Visa PDF forms from the IND site, and go through it next time you see her. Take all the info you can get, and then apply when you are there.
My wife was in Singapore at the time I wanted to bring her here, and it took 10 days from application to visa.
