Hey Joe, do you mean how much for the gear? You can pay anything from £250 upwards depending on quality. No training really required but lots of common sense. I did a three story victorian house two weeks ago and used a camera to see where it needed cleaning {v smart because it was nearly completely clear} but then didn't wear my hard hat when vac was up and a large peice of slate came down and missed me by inches. nearly hit me in my gormless face peering up in the gloom {not very smart}. Where abouts are you?
