Always thought that would be a fairer way of doing it. Trouble is, when I costed this for myself some years ago - it made small jobs quite a lot more expensive, and big jobs quite a lot cheaper.
I was worried that I'd end up losing out on smaller jobs, and getting paid less for the bigger ones. e.g. A small living room might be £65 if you work it out by the area, but £80 if you charge, say at £40 an hour.
How do you get round this - because charging for time is, I think, is a much fairer way of doing it.
