They don't send out the organ grinders until after the job, and not unless you complain.
The chap you will get is the liaison officer.
He is the one who lied to me saying the flue pipe was smashed( I knew it wasn't) instead of saying what the real (big) problem was - damaged asbestos firestop sheets.

As a ex building trade person you will know how
baaaad that is.
If your neighbours are grumbling to you about this work you can now tell them that removal is
essential - a defunct flue pipe alone wouldn't have been.
To reduce their dismay, you can add that mine were damaged and emitting fibres - theirs might be undamaged, but they need removal because they will deteriorate over time.
The lady who monitored the air near the water leak carpet damage has returned with the results - 2 fibres detected, but the 'safe' limit is 20.
People who dont get rainwater washing down the fibres into the living space should not expect to have any at all.
Whilst she was here I showed her the large gap around the pipe going up into the loft from my shower installation.
She assured me that my loft has been sealed - where all piping goes into the loft, the space around the pipe has been sealed from above. She has an honest face - I trust her.
When the liason officer calls, explain your past experience with asbestos so that he won't feel the need to lie to you.
I wouldn't have created a fuss like I did if I had known that it was much more than an intact defunct flue pipe.
