I drove to T5 on Wednesday night to have a Covid test at ExpressTest and to drop my bags off for my Thursday flight to NCE. I managed to miss the email with my test results coming in because I'd been told to expect a wait of about 45 minutes and I was chatting on the phone. In the end it was just less that 30, I left after an hour and two minutes which put me into the next charge rate for the car park - £13.90. Next time I might take the tube.
