no one to inforce h+s law, who will inforce liences.
Enforcement would be helpful but I think that awareness is far more important.
If the public were made aware that there are 2 different levels which window cleaning businesses operate i.e. professional licensed window cleaners and guys who drive around holding their ladder through the sun roof, then they can make an informed decision on who they invite to have access to their property while they are at work.
I don't believe that this is a problem that is exclusive to window cleaning, any trade is open to idiots who claim to be professional and are clearly not. The difference is that most other trades have an established guild or licence scheme so the public can, check that their plumber/joiner/slater/builder is a member or choose to ignore if they so wish.
These trades have a
professional order we do not.
