Typically, you can terminate a hire purchase agreement in writing and return the car at any time. You will have to pay monthly instalments up to the point you end the agreement and if you have paid less than half of the total price of the vehicle you may still have to make payments. If however, you have paid more than half of the price when you end the agreement you cannot get a refund and usually won’t have to pay any more. It is important that you make sure you understand the terms and conditions of your agreement.
