As WKW has already said, the renowned
Tiger Club at Headcorn in Kent is the place to go.
If your friend wants to experience flying a classic British biplane then doing it at the British home of the Tiger Moth is all part of the enjoyment. The Tiger Club was founded in 1956 (originally for pilots interested in racing Tiger Moths) and is still going strong. They have a few Tiger Moths (and other interesting old aircraft) and offer trial lessons.
I've got no axe to grind. I used to be a member, but that was 20 years ago.
