I have never known a trade to talk more openly about what they earn than window cleaners.I have very good friends that own building and electrical companies with 10 plus staff and they never tell me what they earn,I meet window cleaners I don't know tell me how many customers they have how much they charge,what car they have at home etc.
When I started cleaning windows in 1996 I did not know any friends that cleaned windows for a living,now more and more are getting into it I know of an electrician,landscaper,bt engineer,graphic designer plus more all get into window cleaning.
Noone has been asked to announce on this thread what they earn,thats private and would be rude to imo.
If a person averages £40 per hour and works 3 hours per week he makes £120 per week
If a person averages £40 per hour and works 40 hours per week he makes £1,600... Big difference eh.
As far as hourly rates are concerned I would be a fool not to ask the plumber/spark/chippy what he was going to charge me per hour.
Same as if I booked my van in at a garage, I would enquire how much their hourly rate was.
So ask your sparky mates if any potential customers ask what they charge per hour?
