Our offices are still open, just with 10% of the staff in them. And the "£1.6m a month" view is the problem -- if you are spending £5k a month, or 40p a minute

Our offices are still open, just with 10% of the staff in them. And the "£1.6m a month" view is the problem -- if you are spending £5k a month, or 40p a minute, on the costs of keeping an employee (probably more with the cost of office space), an extra £10 a month is neither here nor there. If it costs just 1 minute extra a day, you're losing.
