Most of his friends will rely on bank of mum and dad to pay for everything.
In my experience, parents who turn down the maintenance loan are ill-advised.
The loans are the cheapest and softest money imaginable, and anyone who uses their own money, unless they have money that they would otherwise set light to Bill Drummond stylee, is making a mistake. If your child ends up in a low paid job, you've just given the government money they would never otherwise have received. If your child ends up in a high paid job, repaying the loan is easy. In the middle, you could always use the money you would have given them now to ease their position later.
It will almost always be better to give them that money as a deposit on a house; they would then by (in essence) borrowing the deposit on soft SLA terms, with you as an intermediary.
I have, however, heard of people raising second mortgages, cashing in pensions and spending life savings on avoiding student loans for their children. These are simply bad financial decisions. Any financial advisor (or a reading of MoneySavingExpert) can explain why this is crazy stuff.
For most people, having fifty grand in the bank and their child having fifty grand of SLA debt leaves the child in a better position than the opposite position, because you can later give the child the fifty grand. Being able to reduce your mortgage by fifty grand with that segment of the debt on SLA terms is fantastic value for money for anyone other than someone who's on six figures in their twenties, and those aren't the people I have financial sympathy with.
I could (just about) afford for my children not to have loans, fees or maintenance. My children have full loans, because I've studied the situation carefully.
