Why two years nqt?
It's 2 years now for all NQTs, not sure if this has been the plan for a while, or if it's because of covid, some trainees haven't spend much time at all in an actual classroom, so it ensures more support over a longer period once things return to 'normal', which is great in my opinion.
OP I did my PGCE in primary part time, there is usually a high demand and not many spaces (as not many unis over it), so his application would arguably have to be stronger than if he was applying for FT. I hate to be negative, but salaried trainee positions have been cut to the bone, and even those that are funded through student finance now would likely go to those who have been working/volunteering in schools, so whilst he should look into them, a place is far from guaranteed.
I wish I had just done the year in honesty, my aim was to work part time alongside the course, but between placements, assignments, and uni time it wasn't feasible; I would have rather 'got it over with' quicker, financially there aren't many benefits, other than it delays you starting to earn a wage by 6 months. He should be aware that not all areas have many primary vacancies, despite hearing often about teacher shortages, it's very competitive in many areas, and walking into a job is not guaranteed at all. Being a man may give him an edge, possibly not right, but often true though.
In terms of finance, bursaries were cut a lot this year, there is nought for primary. He could apply for student finance for a maintence loan as well as the fees, but the amount depends on a few things such as household earnings etc, there are calculators to work out a rough guide.
It probably will be tight money wise, but there's a lot of info online that would be worth a look through.
