they have the same sort of agreement in aylebury. I was told by one w/c'er over there that they all got together, agreed "patches" and set their own prices so that they all charge the same rate for the same size house, and if you try to move in on a patch, or undercut one of them, you then have ALL the window cleaners coming down hard, not just one. Whether its true or not I dont know, but I aint got the bottle to find out
