Heh heh this thread is rather amusing I must say Mr Caustic Soda.
The training that I think we need is a specific window cleaning abseiling qualification. At present, window cleaners have litle choice but to go for IRATA as its pretty much the only one that's widely recognized. And, though it is very good and well respected, it is primarily designed for those involved in the off-shore industry, and many window cleaners say its too in-depth for what they need.
Rope-access is becomming more important in window cleaning, especially as buildings in our towns and cities become taller. I think a specific rope-access window cleaning course would be great, but it would have to have the proper recognition (and of course conform to the new British Standard for rope access) if it were to be of any use.

I must clear up one thing though, since you mentioned me by name, I don't run this forum or have anything to do with it other than being a humble member like your good self. I used to be a moderator here, but ah... well thats all in the past. Tosh and Ian have taken up that mantle now, and they're doin fine.
