Lenders like to see a solid record of your credit history as this will help them to determine how reliable you are to lend to. If you have no credit history, then you are considered a greater risk to lenders and as a result - you may find it more difficult to be accepted for car finance. However, if you apply for car finance with no credit history, you still have some options open to you. You may be required to pay a substantial Deposit to offset the risk the lender would take with granting you access to credit.
Alternatively, you may be able to take advantage of a parent’s good credit history and request for them to be a Guarantor. Similarly, if you have a partner with good credit, it’s possible to start a Joint Application, which could be helpful if you have no credit history yourself.
