Is this possible in central London?
DS really likes tennis and he has been in classes where there are loads of kids and they don't get to hit the ball much, let alone play a match.
The coaches charge about £45 for a private lesson, and the schmantzy clubs nearby are very expensive to join (monthly fees + class fees on top) and you can't book if you aren't a member.
I don't drive, so getting out to Roehampton won't be possible.
