West London Aero Club i believe do one. It covers the bare essentials of flying.
I dont believe it can make anyone a safety pilot as a safety pilot must have a pilots licence. I thought the safety pilot is simply someone who is able to double check what another pilot is doing (ie. if the pilots a little rusty or need advice).
Id be very careful with someone else doing your RT, as there is more chance of a mis communication. To take the weight off as such you could always invite your dad to keep the plane steady?
