Booking a court is very straightforward, you just need to sign in using your LTA profile, your Google or Facebook profile, or you can create your own profile. The system will then send you a confirmation email which you can forward to the member you are playing. You can book a court in half hour slots with up to four slots available for each booking, ie 2 hours.
Please note courts are unavailable for booking during social tennis times, when home League matches are being played and when there are official coaching sesions at the club. These times are indicated on the booking sheet. Social tennis has priority over any bookings which follow the social session, so if play is continuing you would have to wait until the court is free. In practice this is unlikely to be a big issue.
