Bit of a rant but to put it into context, I am currently a one man band and extremely busy! I had some guy phone me earlier asking for a price for his solar panels to be cleaned on a 2 story house. Not a regular customer and just a one off clean. I quoted £10 per panel as I didn't fancy taking the job on for any less than that. Customer point blank down the phone "Thats a bit expensive isn't it." The question is... What is expensive? Surely all price is relative. Would he be up there on a ladder scrubbing his solar panels for £10 a panel? I very much doubt it.
