I have 14 year old twins who are fairly academic. I see both driving and university as important and I hope we can achieve both somehow.
Both my brother and me were lucky to be able to get a full grant for uni a long time ago now.
I've always known we'd have to fund uni - and plan ahead - but we didn't know we'd have twins and have to pay for two simultaneously!
We are on less than you OP, our combined earnings are in the 50s but still only qualify for the same loan you are being quoted on 70k.
Since birth I have saved bits in a child trust fund - around £50 each a month, even when I was made redundant and we lived off DH salary of £27k. Sending the children to uni was always a priority as I dropped out, DH, 47, never went and his salary will never increase beyond the early 30ks.
My brother and me were the 1st in our family to go to uni and nobody in DH's family has ever gone, so I will do what I can to send mine - downsizing our house, taking a 2nd job etc.
We now have around 10k and hope to have 15k each, maybe 18 for their 18th birthday.
We are lucky that we have several unis on our doorstep and live in a fairly cheap city. Hoping they might stay at home to cut costs further.
OP, do you work full time? Sorry if it's been mentioned upthread, but if not then can you increase your hours?
Definitely cut down on clubs. We have always been quite strict with what we'd spend on these - probably 1k per year.
Good luck.
