Almost certainly preparing you for a scam. Work permits are very hard to obtain now for non EU residents and restricted to those who possess special skills in "shortage occupations". We have had a huge influx of Eastern European migrant workers to fill the unskilled and semi skilled jobs. Unless and until you have a work permit in your possession, and you are 100% sure it is genuine, maybe by asking for verification at the British Embassy, I would recommend you don't take this seriously and definately don't part with any money. My real advice would be to forget it now. I get asked very frequently to "find me a job" in the UK and some Filipinos find it hard to accept that it is simply impossible now without the skills. Unless you are a doctor or a nurse you have little chance.
