Outbound: Vaccination form, Spanish passenger locator form with QR code. This has to be done online but the resulting form with QR code can be printed out. I took printed copies of both.
Return: Certificate showing a negative covid test taken up to 48 hours before departure, UK passenger locator form completed and printed out with QR form up to 48 hours before departure, which requires having booked a Day 2 test on return.
Just about to take my Day 2 test and post it off, and hopefully that will be that. Until I go to Italy next week...
