bosh, no it's not a regular clean, probably 3/4 or so times a year, also clean the restaurant carpet and hallways at various times of the year, i will say that i would possibly charge less if it was very regular, ie monthly. are your prices too cheap? i think it's what you earn by the hour that matters, even if you are only charging 20p per sq mtr as long as your earning the hourly rate you want, so be it,
