its defo on the increase but theres still a lot of trad guys out there.most dont have the money to invest in wfp though and are fearful of making the change/learning a different way of cleaning due to fear of losing customers.
Money and what the customers might think are the two things I hear most as well.
As far as money goes, it's true that many will need to take on some debt to make the switch. Initially, there probably won't be extra turnover to service that debt - indeed, some will lose a few customers. So there is an initial period of gettig used to WFP which can mean going slower at first. The good bit comes a bit later when the speed comes. At one point, some years ago, I had a six-weekly round that I was servicing in three and a half weeks. The mistake I made was in filling much of that gap with subcontracted commercial (and some residential) work rather than getting my own work.
I also hear some worrying about what the customers will think. This is only valid if the customers act upon those thoughts. I lost a few jobs over it. I also experienced a higher number of mystery cancellations than normal. It can take a while to start getting work BECAUSE OF WFP. It happens fairly regularly now though.
