Complete lack of clarity as usual from the government. It doesn't state what type of test is required either. Is it the more expensive, more accurate, slower PCR test or the cheaper, less accurate, much faster lateral flow test? It's taking shutting the stable door after the horse has bolted to a new level too. If one in fifty have the virus in the UK already, it is pointless. It should have been brought in during the early summer when cases were much lower here.
I flew to the UK the week before Christmas. No checks were made by the airline or at the border. I can't imagine many others on my flight did it. You'd expect to see people carrying it around with their passport (like a printed e-ticket or e-visa), but I only saw one or two with it. I completed the form, but I wasn't contacted by phone or email about the quarantine period. I can see why the compliance is so low.
