I did my first Covid test at home yesterday and sent it off.
The rules for people returning from abroad from non-red list countries are we have to self-quarantine at home for 10 days and submit a Covid test on days 2 and 8. These go off to an NHS testing centre but are not free, I have had to pay £210 for the privilege but that is still better than having to pay for hotel quarantine.
I feel fine and won't have Covid unless I picked up something on the plane journey home, so hopefully all will negative.
