Consulting (Ltd co) expense claims

[WTFH]

My clients are "finance types" and I meet them at their location, which is most often in the countryside.

Nice and vague there (as NLUK has pointed out)
"Finance types" tend to have corporate offices, which are rarely in the countryside.

Is the countryside location maybe their home, or a local pub/restaurant/activity location?
Are you organising these meetings during normal business hours (mon-fri 9-6)?
Are the group of "finance types" that you will be meeting the same people each time, or is it one company at a time, and different companies?
