Does anyone charge a higher day rate than the weekly rate? A good client of mind has asked me to come in for just 2 days but the associated rail costs for single days works out as double that of buying a weekly travel pass (i.e. £30 per day versus £80 for a week). I'm hesitant to ask for more for single days, especially if this is out of the norm. But I'm also hesitant to work in a way where my profit is so very low (20% tax, 26% on travel etc so I keep just 54% of the fee). Please let me know your thoughts.
