WALES; registered letters sent to your self-isolating address

[martincymru]

So the postman comes, you sign and that is the end of that:

“ international travellers must provide contact details, including the address where they will self-isolate. Public Health Wales will write registered letters to these identified individuals. If the letters are returned, one phone call will be made. "
