I never charge over the odds for 1 offs that way i get them again.

Quote of the year that !!  I've loads of one offs that i do cheap but they're not one offs, oh hang on.........

Lol what i meant by 1 offs is
People who are iregular ie every 4 months up to a year who phone you up as and when they like.
At the end of the day if you dont overcharge them you are likely to get work from them again.
If you charge them double the going rate you probably wont see them again.

I always ask if they want monthly,some say "depends on the price"
I then reply the price depends on the frequency.
Usually the good uns ask how much for every month,the proper one offs will still ask how much for 1 time,then you know to charge accordingly.
That said i sometimes price a daft amount if i dont want to do it for access or other reasons that annoy me,overgrown garden/gear all over the place etc,even if they want regular cleans.
