@MyGPgood my understanding is that the first 4 years are like normal students, so around £5k top up and years 5/6 if on 6 year degree or intercalating they get £1k + a reduced loan of around 2.5K.
So if topping to full loan that would be around £5k for years 1-4 and £6k for years 5-6. Total £32k.
Actually, many parents who afford to, do what @mumsneedwine did and pay for accommodation for the 6 years.
BUT it depends on where they are living and whether you expect them to work. I also think that parents might need to top up further as the loans have not been increased to reflect the increase in the cost of living, so I think they might need another £1,000/year on top of that, whether they earn it or parents provide it.
I think you might be able to manage in Sheffield, Leicester, Newcastle with an income of £9.5k pa, but not in Bristol, St Andrews, Manchester and others.
