All universities have their accommodation costs on their website. Some places like Durham the cost is the same but with slight increase/decrease if they share a room, have an en-suite sort of thing. Some places have catered and self catered, Loughborough, Nottingham, Durham. Some vary wildly in cost. My youngest is at Warwick so first year halls were anything from £128 pwk (40 weeks) so £5120 up to £255 or £10200 which is quite frankly ridiculous. We paid just under £8k for en-suite first year room.
Ds is in private halls of residence for second/third year (now) and we are paying £8k. Then it comes down to what they pay out to live. Laundry, costs are usually on uni pages as they have a typical costs page, usually around £5.50 for a wash and dry per load. Mine does 2 loads per week, one clothes the other bedding and bathroom towels.
Then Netflix, Amazon Prime, Spotify, phone contract, any course materials, travel costs and socialising. Ds is not a drinker but does socialise on soft drinks. Supermarket shops vary, mine spends about £40 a week but eats things like salmon and steak, he loves cooking. We give him £100 per week term time only. He has savings from this.
We provide clothing basics, a toiletries stash plus a kitchen cupboard stash so pasta, pesto, tins of soup sort of thing.
There is also the initial layout cost for their room. This can come from spares in your house, we don't have spares so everything from duvet, pillow, bedding, towels, kitchen items, chopping board, pans, plates etc had to be bought. We bought for our eldest and these were passed down.
Even if you can afford to pay for the tuition fees and her living costs I wouldn't. I would instead give them money for a house deposit. Ds1 graduated, started out on £33k so take home monthly pay of £2246.30 and student loan payment of £60 if adjusted to the new payment plan 5 (he is on payment plan 2 and would only pay £27). So compare that take home pay and consider how long it would take them to save for a house deposit.
Saying all that, Ds2 will have cost us around £19k for all 3 years at uni. He got minimum maintenance loan, we topped him up to over the maximum maintenance loan to pay him the same as his brother's weekly allowance.
