Hi there, first trip abroad since the pandemic started and trying to get my head around the rules. Per the Gov website, I only need a day 2 lateral flow test on return to the UK. My understanding is that I can purchase and have this delivered before I fly so that I already have it when I return. I then have the booking reference for the passenger form. Then I can simply take the test at home on/before day 2. Provider websites say I then take a photo of the results together with my passport, email it back and get a verification certificate.
Have I understood this correctly? It sounds deceivingly straightforward compared to previous rules which is why I'm second-guessing myself! Thanks.
