Hi. You haven't had much luck. We only found out about the CFO through girls that my wife met at Hopkns TOEIC in Makati.
Anyhow. THE UKBA does not require a chest x ray for those from the Philippines. However it seems they sometimes still ask. (You can verify this on the UKBA website)
My wife has never been asked for and never has had a chest xray and she has been here for 5 months!
