And how does that sit with HMRC?
Genuine expenses for carrying out their vocation. Plenty of previous genuine claims to support that argument.
Also promotes efficient and greener practices.
What's not to like?
I appreciate the efficiency, but it sits counter to the general principle of transparency in their dealings.
If transparency is more important than efficiency, so be it.
But the same applies to plenty of other types of expenses, e.g. some organisation will pay an overnight subsistence allowance if the employee is, say more than 100 miles from office (not home) at the end of the day. otherwise it is travelling expenses. Usually that allowance is a fixed sum, if the employees chooses to stay at the Ritz, or in some hovel they still receive the same amount. In some cases, if a stay in a cosmopolitan city is required, either a properly audited expense claim is required or the organisation makes (and pays direct) the booking.
There are so many examples of fixed rate expenses.
Another example, for entertaining, say clients, if the client is not really important at all the venue might be Smokey Joe's cafe. Otherwise the venue might reflect the importance of the client. If the same fixed expense applies regardless, it is swings and roundabouts.
Another example, Car hire expense, if one wants to arrive in style to impress, one hires a classic car, or a helicopter, otherwise it is a budget rental.
I don't know who introduced the issue as a point of order, but from my experience it is common practice and a preferred, more efficient approach.
If employees/politicians choose not to utilise that expense allowance and pocket the cash, they should not be employees/politicians in the first place!
Unless, of course, they have driven the model of efficiency to the limit.
