why would you need certificate for window cleaning waste of money if you had to pay for them as Ive got loads of commercial buildings with only the one important certificate & thats Insurance, mind you I also send in method statement & risk assessment some ask for H&S papers but my respond is that they just take your money for a certificate I feel that H&S is common sense really & they agree so I feel all this training and so on for some sort of paper is a waste of time my opinion Bobski Ive built a good family business with nooooone of that rubbish !!! All down to who you know & how you approach people ........ Thats how you get on with running a good company OOOO yes & good hones workforce if you have any !!! look after them & they will look after you !!!!!!
