I may be wrong but I think someone like TCTCS is hired by big companies.
Then they go to the sites of the company and carry out inspections.

Looks like some interesting vids on their YT channel. One thing confused me about that particular vid, they way he talked sounded as if he was doing unannounced visits to companies, which made it sound like TCTS were an official organization, but as far as I can see they’re a private company.
Reckon youre right, here is their site [tctsgroup.com/about-us/](http://www.tctsgroup.com/about-us/) The blue/silver badge and bold black/white chequered band on the hi-vis makes an impression though doesnt it?
