Process of handing back your vehicle We want to make the process of handing back your vehicle as simple and transparent as possible. Which type of agreement do you have? To make sure we’re giving you the right information, please choose one of these two options: Purchase My agreement lets me own the vehicle, such as a PCP, Conditional Sale or Purchase Plan. My agreement number is 14 digits starting with 100. Contract Hire I have a Contract Hire agreement where owning the vehicle isn’t an option. My agreement number contains 2 letters followed by 6 numbers. You can find your agreement number on your agreement documentation. We only manage motor finance agreements.
