We’ve paid accommodation and let the three live on the min loan. Frankly I’d suggest that £4.4K which is about the min outside London should be more than adequate if accommodation already covered.
However accommodation costs can vary widely.
DS1 went to Cambridge, very old, central and wealthy college. Everything heavily subsidised or free. Accommodation around 4K excl. food. He only had en-suite in y1, but other years same massive room, fireplace, separate sleeping area shared bathroom with two other rooms. He had a 10x6 rug which tbh looked lost.
DS2 and 3 in y3 and y1 at different regional unis. Both had the full en-suite yr 1 halls, just over 6k for DS2, although that same hall this academic year would be over 7k. DS3’s accom probably higher spec again, certainly bigger room but costs 5.5k. Both were / are self catered.
DS2 second year house just under £400 per month plus bills. Same but with bills for the flat DS3 is due into in y2. Although he’ll be in a seafront apartment with the beach across the road. DS2’s house this year much less around £200 per month plus bills , seriously nice but a bit further out of the city.
So this year for two of them not too much over £8k accommodation wise.
We do pay for phone contracts, although not huge figs, and they have access to Spotify, Netflix etc. DS3 is a 6hr+ drive away so any visit will be for a few days with hotel costs to factor in.
