No, I bought a short set of B&Q ladders; dodgy ones, but very light and short.
They sit on the front of my estate lovely, so I can work from the boot.
I use them mostly for accessing the odd flat roof; but to be honest I do use them for the occasional house I don't use WFP for; a couple of houses that have badly oxidised windows (in amongst a load that I WFP) and four really elderly (nearly-dead-types) folks houses, who I don't want to frighten with new-fangled methods of window cleaning.
One lady is deaf, blind and really frail (I don't fancy explaining it to her), another lady is German and really hard-headed (I'm frightened to explain it to her), and the other two would be no problem; but they all live next door to each other; so I do them all with ladders.
I wouldn't use B&Q ladders more than I'd have to though. They're really wobbly!
