Cost of kids at university

Try this out. I remember looking into it, but my oldest is only 8 😅

It's a real 'how long is a piece of string?' question, depending on all sorts of things.
Mostly accommodation costs.
But also, how much paid work you expect them to do.
Accommodation choices.
If you are including travel.
If you are including getting there and back at the start / end of term,
What their expectations of living are - from what you say about spending now, they are used to having a lot spent on them / lots of new clothes / activities. So their 'expectations of what is normal' will be different from those who don't have hundreds of ££ spent on them.
Can they cook ?
Do they understand about freezing things / using up leftovers ?
Do they think buying a coffee out is a normal, regular thing or a treat ? (as an example.... meals out / takeaways / nails done / having the latest gadget or phone / buying this season's football shirt / etc/etc)

I think most parents make up the difference between the loan their child gets and the maximum loan. We don't give our son any money but we take him to do a food shop at the beginning and middle of each term and take him out for lunch.

I topped ours up from the minimum to the maximum loan most of the time they were there, so that's a good starting place.

We did pay hall fees for the first year for our eldest, and then they lived on their loan. Our youngest had much cheaper accommodation available at their uni, so we just topped up to the maximum.

If they can get a part time/summer job then that covers luxuries/holidays.

It’s so variable, some Uni’s are far more expensive than others, are they going to be expecting to work in holidays or the summer before they go? I would budget £10,000 a year per child and you won’t be too far away
