What lenders actually want to see
A verifiable regular income of at least £1,000/month is the starting point. That can be part-time work, an apprenticeship, a contract role, or a mix. Student loan payments don't count as income for affordability purposes.
The guarantor route
A parent or older sibling with a stable credit profile can guarantee your loan, unlocking sharper rates and higher approval odds. The guarantor is legally on the hook if you don't pay — so it's a real ask.
Vehicle choice matters more for students
Insurance for under-21s is often £2,000-£4,000 a year on anything larger than a small hatchback. Pick a low-insurance-group first car (Corsa, i10, Picanto, Fiesta 1.0) or the finance itself will be affordable while the total ownership cost isn't.
Building credit while at uni
A car finance agreement paid on time is one of the best credit-building tools available to a student. By graduation, twelve on-time payments will meaningfully outperform a peer with no credit history at all.
