Hi we returned to the UK and had to book day 2&8 test before we could complete our passenger locator form costing £308 (rip off) the day 5 release is extra so we chose to isolate for the 10 days as it was an extra £79 each (disgusting) .
We both had separate calls everyday and we had to wait until the 11th day as we found out you can only finish isolation once you have the positive day 8 test back.
I know this may sound negative but it's reality and it's a joke, we are living with our daughter and grand children when back in the uk and they could carry on as normal, so to me it's just the government justing trying any way they can to get money back.
Good luck with your trip and wedding hope I haven't put a downer on it.
