the thing is mick you can charge what you want to a degree!IF you look professional and do a good job!
i have lots of work ive picked up over the last few years which is much better priced than some of the windows cleaners around me BUT they dont clean doors or frames,cant clean windows above connys,velux windows,they dont do add ons like fascias,solar panels and roofs.
with the explosion of WFP that is slowly changing.most of us have undercharged at some point.usually when starting out and esp years ago when overheads were a lot lower when trad only.
and people do window cleaning for different reasons.some are older guys who top up their pension,others are trying to make a few extra quid on top of their regular job part time.others are supplementing their benefits,beer money etc.
i have 8 days of work that are very compact 3 bed semis.lots are under a tenner(i clean the backs as well as the fronts!)i would say these are underpriced but im slowly creeping them up.i earn ok off them and they are good reliable customers.
if you live down south and around the london area your going to charge a lot more as the cost of living is a lot higher(i know cos every time i go visit my brother who lives in wimbledon im shocked by how much everything costs!).
i wouldnt call people who charge less mugs.just as i dont call guys who charge a lot more greedy!
the truth is there is a vast array of different personalities,needs,attitudes,cost of living in different areas around the country etc that pricing will always we different.
and YES different prices in the same areas!
best wishes to you all
