No. But how much are you claiming as mileage expenses?
Might be better to - and there are also good reasons not to (ie tax) - take a salary and lend the net back to the company. Otherwise;
- company accounts won't show an accurate picture of the time/effort/costs to get those results
- you'll have suffered the classic double-hit when you do go to withdraw a salary (as you'll have paid corporate tax on the profits; and then paying your gross salary from those after-corporation-tax profits)
