With more and more wfp systems on the streets, it will be of benefit to us all, because those customers who are unsure of wfp cleaning will see it becoming more acceptable by their neighbours and this will change their minds.
Pricewise, it won't have much affect on the domestic market, you will have the newbie who starts up and starts charging silly prices, but as soon as he realises that he can command more per job then his prices will increase.
The commercial market is very different, the price on these jobs will go down, mainly because cleaners are charging Trad prices because that is what they are used to, now they have started using wfp and they now can clean these properties faster, but their price does not reflect this.
A new cleaner who has never cleaned windows before and starts up with a wfp system, will charge cheaper because a wfp system is faster than a ladder user.
