Expenses on Client Visits

We have 2 workplaces in Edinburgh and Glasgow. Our Glasgow based Employees (who work from home) work in Edinburgh for 1 day a week. Due to the fact there is no end date to this arrangement therefore it does not comply with 24 month rule or the 40% rule, it is classed as a permanent workplace, however the Glasgow based employee goes to Edinburgh for a client meeting, but goes into the Edinburgh office for a couple of hours to work their normal duties afterwards, how do I treat the expenses then?

Hi,
