Anybody live in the UK near Feltham/Heathrow?

I am looking for a room or shared accommodation for an 18 year old young man that I have been supporting that I have helped immigrate to the UK from elsewhere in Europe. He works at Heathrow, and I would like to find a safe place for him to live. If anyone has a way to help me find a safe place for him, or has accomodation to rent, let me know. [I am in US.]
