My flat was the first on this road. They are working their way downhill.
The air monitor is buzzing in my lounge now.

I had a chat with the young woman who brought it.(independant monitoring company)
She says that the position of decontamination chambers on the exit route to the door has been changed on the flats done after mine. It will no longer be possible to get access to bathroom and bedroom with the sheeted tunnel in place. She personally inspected the exit tunnel before work began on my flat.
