I have 2 daughters at uni currently. Both get just above minimum student maintenance loan. We make up the difference. We did save up a fair bit over the years towards their education... but... practically, what we have done that has helped was
Look local. Neither wanted to stay local in the end, but one Dd is an hour away by train, the other 2 and a half. Easy to get home for a long weekend.(especially with a railcard).
Gap year. Both took on a job for a year, this has provided a lot of the "I'm not giving you money for that" money ... trips with friends etc, as well as towards rent. One has social issues and worked on phone lines for virgin during covid which was a baptism of fire. The other worked in a pharmacy, out back, putting pills in doset boxes. She now does exam invitation at a local school, and for the 6th form college - quick training, rewarding, much needed job, fits after her exams, before summer break
Both made over minimum wage for a year.
One is looking to teach, bursaries are available.
Where there's a will to do it, a way can usually be found. We are at 2 years to go. It's a pinch, but there's light at the end of the tunnel.
Would also suggest apprenticeship route for programming. Look at Civil service, GCHQ, local school IT departments as well as any bigger firms with local HQs. It is an adventure, good luck.
