He isn't equipped to move out. As far as I can see;
He hasn't got the money for deposit, first or any subsequent month's rent
Hasn't got basic impulse control with his loan and overdraft.
Can't cook won't cook
Has no real idea of how much things cost and how he's going to pay for them.
I think him moving out is a great idea. The commute isn't too long, he just wants to be able to go out drinking with his mates more and pull a few girls
- but living independently is what he needs to do to grow as a young man, he just needs to learn what TO do to achieve that.
I'd start with a home truths conversation with him. You can't afford to finance him, but will help him work out how he can afford to. Help him work out a basic income and expenditure budget. For weekly and monthly things like phone, rent, food, beer, transport, and the bigger one offs like the trip and buying pots and pans and a laptop and printer etc to equip his digs. Put in the remaining student loan he has in his bank, and work out together the shortfall. Reiterate that you can't help him financially, and help him to work out how much he would need to get extra in hardship grant, loans or work income.he will need to get himself a job and save up for his deposit, trip etc if he wants to move out. He will need to pull his finger out regarding the hardship fund - I'm angry with him myself that he's too lazy to even ask how he finds out more about that, yet expects you to take out a loan you can't afford instead - no chance!!
He will need to learn how to do a basic meal plan and shop and cook accordingly. Or not - plenty get by on 12p noodles (and yes yes to the pp who said frozen veg and stuff in theirs - mine was peas and grated cheese!).
