I am thinking of contributing a lot more than I had been to my children’s JISAs, with a view to having at least enough money to pay their university tuition (they’re 2 and 5, so a long way off yet!). I hope by the time they go to university (if they choose to) we’d be able to fund their tuition, but this is a backup if not. If they have a significant amount of savings in their JISA (£40,000+ each) would this currently affect their ability to get student loans, or cause them any other detriment?
