Handing back a car on finance in the UK: your right under section 99 and the half rule
If car finance payments have become too much, the law lets you hand the car back and end the agreement early — voluntary termination. Under section 99 of the Consumer Credit Act 1974 you can end a hire purchase or PCP agreement any time before the last payment. Under section 100 you pay no more than it takes to bring what you have paid up to half the total price. Here is who qualifies, how the half is worked out and what it does not cover.

Have the payments on your car finance become too much, while selling the car would leave you owing more than it is worth? In the UK a borrower has a legal right to hand the car back and end the agreement early — voluntary termination. It is set out in the Consumer Credit Act 1974 and does not depend on the lender agreeing. Here is who qualifies, how much you pay and where the traps are.
What voluntary termination is
It is the right to end a car purchase-by-instalments agreement before the final payment falls due. Section 99 of the Consumer Credit Act 1974 says plainly that the debtor may end a regulated hire purchase (HP) or conditional sale agreement at any time before the last payment is due, by giving notice to the person entitled to receive the payments — the finance company. The right is given by statute and cannot be removed by the terms of the agreement.
Which agreements it covers
Regulated hire purchase and conditional sale agreements — which is most HP and PCP (personal contract purchase) car finance. Both HP and PCP are structured as purchase by instalments with ownership passing, so they fall under section 99.
It does NOT cover personal contract hire (PCH) — long-term rental, a lease with no option to own. That is hire, not purchase, and section 99 does not apply. If you are unsure which you have, look in the agreement for hire purchase, conditional sale or PCP (covered) versus personal contract hire, lease or contract hire (not covered).
How much you pay: the half rule
The key figure is one half. Section 100 of the Consumer Credit Act 1974 caps your liability: you must bring what you have paid up to one-half of the total price of the agreement. If by the time you end it you have paid less than half, you top up the difference to 50%. If you have already paid half or more, you owe nothing further on the principal.
Crucially, the total price is not the value of the car but the whole amount under the agreement: the price of the car plus interest and compulsory fees. That is why on PCP the 50% point often comes late: the large final payment (the balloon) is part of the total price and raises the bar. The lender must tell you the exact half figure on request — it is also stated in the agreement.
Why it beats selling
Because the law caps your payment at half the total price, the gap between the car's market value and the outstanding balance does not matter. If you sold the car in negative equity you would have to cover that gap yourself; with voluntary termination you do not. That is the point of the right: it protects you when the car is worth less than you owe.

Section 100 requires reasonable care of the car. Fair wear and tear is fine and is not charged for. But for damage beyond fair wear and tear the finance company can bill you: your payment is increased by that amount under the Act. So before handing it back it is sensible to photograph the car and fix obvious damage if that is cheaper than the bill. The excess-mileage charge that applies when a PCP runs to its end does not arise on voluntary termination — you are not completing the agreement but ending it.
Arrears first
Ending the agreement does not wipe out what has already accrued. Section 99 states separately that termination does not affect any liability that arose before it. If you are behind on payments (arrears), they must be cleared — they do not disappear and can be added to the calculation.
How to do it
Send the finance company written notice of voluntary termination (by letter or through their form) and keep proof of sending. Refer directly to the right under section 99 of the Consumer Credit Act 1974. Arrange to return the car and have it inspected. If the company demands more than half the total price or tries to talk you out of it, the right remains yours; under section 100 a court may even order a smaller sum if the lender's actual loss was lower.
In short
Voluntary termination is a lawful way out of HP or PCP car finance: you pay no more than half the total price and are not liable for negative equity on the car. Check that you have HP, conditional sale or PCP rather than a PCH lease; ask the lender for the exact half figure; clear any arrears; return the car in reasonable condition and keep the notice.
