Bumped into a window cleaner the other evening at the petrol station. He popped over to ask about the guttervac in the back of my van, as he was looking into getting some for his firm. Asked whereabouts he worked - answer was "London, mostly Chelsea, Kensington etc". Asked him what kind of houses, prices he charged etc. Basic answer was "£4 a window, plus £2 extra if they want the frames/sills doing. French doors & larger windows £6+"!! He then got back into his Porsche & drove off. So where I would charge £12 for a bog-standard 3 bed semi where I am, he gets £50+. Might have to move.
