You know the scenario well - self-employed decorator, moving between sites within a local area. If I ask about meal claims, he'll say 'I couldn't get home to eat'.
I've read BIM37670 and BIM47705 and other bits of BIM, and the issue seems to rest with itinerancy. 'Jobbing builders' can be itinerant - but is that only when they're away from home for periods of time? I don't have an issue with the travel - that is from his base (home) to various places for various jobs, it is itinerant. But meals when he's within 10 miles of home seem to me to be different.
Anyone have any direct experience on this one?
