After 3 years it’s not unreasonable to have accumulated some 30,000 miles. If they’ve no means to assess and collect outside the MOT, that could be a rather instant and sizeable £900 bill on the car. Given many Scheme customers aren’t working, a sudden unexpected bill of that scale could cause problems.
There really should be some kind of payment process that allows those on a limited income to pay an affordable amount each month and then an adjustment to that based on each opportunity to get the real miles.
