if you already have a good amount of work investing in wfp will be a smart move esp if your a sole trader.
over 5 years my expenses work out at around £5,000 a year.when i was 100% trad it was more like £2,500 a year.
mines a DIY system though(tank/frame/pumpbox)and expensive hi modulus carbon poles.a cheap,clean second hand van signwritten.lots of work within 6 miles so hardly any money spent on fuel.
you ll work in the rain and most inclement weather,youll be faster after a few months(esp if you have a van mount and 100m microbore)and you ll be able to clean larger,more awkward properties a lot faster than ladders.
of course there is the option to offer other cleaning services as well(f/s/g,conny roofs and solar panels)which all add up to extra income.once your familiar with cleaning these jobs,if you price well you can earn more money on them than regular window cleaning.
your working day will be shorter(actually window cleaning not including "end of the day" jobs like purifying water,charging batteries etc)
you ll enjoy work more(i do anyway than i used to climbing ladders all day!)
you should earn a lot more money over the course of a few years that goes well beyond the expense of wfp once your up to speed.thats what ive found anyway.
ive picked up a lot of good jobs because i use a wfp system rather than ladders.
i should top over 20k extra a year this year than 5 years ago when i was 100% trad so for me its been astounding and a brilliant move although i didnt think so at the time back then.
so is it worth the extra £2,500 a year in expenses compared to trad only?easily!
