None and i also do the job my teachers said i would end up doing. 

Nice one but they didn't think you would earn more than them

Though this question is not relating to qualifications but how do you price an office cleaning  contract job in London  ?

@Charms

Welcome. I would put up a thread in window cleaning issues and ask the same question. Provide some details as to the size/type of contract and you'll get some help I'm sure.

I have a degree in psychology and started into window cleaning. Honestly wouldnt even look back

I've found that about 0.5-1% of customers in this game are nutty as a fruit cake.
What's your take on this?

I would suggest that the true number is far in excess of 0.5%-1% lol
