Yep, I charge £50+vat / hour, 400+vat / day. Remember that that's what's being charged, not what's being earned. As a sole trader my business overheads are circa £18k a year. That's 9 weeks worked just to earn enough to keep the business running, nothing in my pocket, and that assumes I get 9 weeks worth of full days, which in reality doesn't actually happen. Add 5 weeks of holiday into that and that's easily 3 months a year of no pay.
