I have a minimum price now of £25, so that would be my price. But I do not need the work, as I have plenty of well priced jobs. But if I was starting out and desperate for the work, and I was hoping to get a lot of work on the same estate, I would probably go in at £15- £20. I did this when I first started out, on a new estate, and had almost 100 houses on this one estate. I don't clean any of them now though, as I prefer my well priced work! So don't go in too cheap, because you will soon get fed up of working so hard, for not much money!!
