To think re-marking GCSE shouldn't be a 'no win, no fee' style gamble?

[MarvellousMonsters]

Eldest has just got GCSE results, all 7, 8, 9 so we are very happy with them. However today we got emails saying some are within 2 marks of the next grade, and we can have them re-marked. The catch is, if the grade stays the same we will have to pay £50 per paper, (if the grade goes up there's no charge) and each GCSE has 2 or 3 papers, meaning asking for re-marking is effectively gambling £200-£300 per GCSE.

A friend is a teacher at a different school and they don't charge anything for re-marking.

Is our school BU?

No. If they paid, everyone would want their papers remarking and the money has to come from somewhere.
Some schools will pay for the papers that they select to be re-marked, as it is only a few and they genuinely believe the mark will go up.
