Gave up trying to book online and found out on Royal Borough of Ken & Chelsea’s website that they have a mobile unit behind Co Op at World’s End end of King’s Road. Rocked up with my DC and got tested. It was brill - no queues and you can register online or on the phone (119) after the test. I don’t k ow if they will be there tomorrow as they are moving wherever there are spikes. Keep checking the website.
