How can he think of needing something he is already out of control of ? He is not thinking straight.
He needs to explan the situation, and in the meanwhile in his shoes I'd get advice, probably from Citizen's Advice as a first port of call. He needs to budget, he needs his lenders to realise they won't be able to get blood from a stone, and so offer an arrangement. Or perhaps he can declare himself bankrupt ? Seems extreme for £600 but may be worth bearing in mind if he can't turn it around.
