Can You Part-Exchange a Car That's Still on Finance?(2026 Guide)

Short answer: yes. You can part-exchange a car that still has outstanding finance on it - it happens every day. But whether it's a smart move, and how much it really costs you, comes down to a single number: your settlement figure compared with what your car is actually worth. Get that comparison right and a part-exchange is smooth. Get it wrong and you can quietly roll thousands of pounds of old debt into your next car.

This guide walks through exactly how it works in 2026, with plain worked examples for both positive and negative equity, so you know where you stand before you set foot in a dealership.

Why the finance has to be settled first

Until your finance is paid off, the finance company - not you - legally owns the car (this is how Hire Purchase and PCP agreements work). You can't sell or trade in something you don't legally own, so the outstanding balance has to be cleared as part of the deal.

In practice, the dealer handles this for you. They obtain a settlement figure from your current lender, pay that lender directly to close your existing agreement, and set up a new agreement (or a cash purchase) for your next car. You don't end up juggling two loans - the old one is closed as part of the transaction.

The one number that matters: your settlement figure

A settlement figure is the exact amount needed to clear your finance agreement in full on a given date. It is not simply your remaining monthly payments added up - it usually includes an interest rebate for settling early, so it is often a little lower than the sum of the payments left.

Under the Consumer Credit Act 1974 you are entitled to request a settlement figure from your lender at any time, and they must provide it. You can ask before you even start looking at a new car, just to know where you stand - most lenders now show it in your online account or app.

Positive equity vs negative equity

Once you have your settlement figure, compare it with what your car is worth as a part-exchange. That comparison decides everything:

• Positive equity - your car is worth more than the settlement figure. The surplus becomes a deposit toward your next car.
• Negative equity - your car is worth less than the settlement figure. The shortfall is a debt that still has to be dealt with; it does not disappear.

Before you go anywhere, get a realistic idea of your car's value from more than one source. Our guide on how much your car is worth covers the valuation tools worth using.

Worked example: positive equity

Say your settlement figure is £6,000 and the dealer values your car at £8,000. You are £2,000 in positive equity. The dealer clears the £6,000 with your lender, and the remaining £2,000 goes straight toward the deposit on your next car - reducing how much you need to borrow.

Worked example: negative equity

Now say your settlement figure is £8,000 but your car is only worth £6,000. You are £2,000 in negative equity. That shortfall has to go somewhere. You generally have two options:

• Pay the shortfall in cash - you cover the £2,000 gap yourself and start your next agreement with a clean slate.
• Roll it into the new finance - the £2,000 is added to your new agreement, so you borrow more than your next car is actually worth from day one.

Rolling negative equity forward is common and can be convenient, but it is worth pausing on: you start the new deal already "underwater", and if you change cars again before you have caught up, the problem compounds. If you are in this position, a sensible move is to choose a keenly-priced next car and keep the borrowing tight, rather than stacking debt on top of debt.

These figures are illustrative examples to show how the arithmetic works - your own numbers will depend on your agreement and your car's current market value.

Note too that rolling negative equity into a new agreement is never guaranteed - whether a lender will allow it depends on your personal circumstances, the lender's own criteria, the loan-to-value of the car and other factors.

Does HP or PCP change things?

The settlement-figure principle is the same on both, but there is one useful difference. On both Hire Purchase (HP) and PCP agreements, once you have paid at least 50% of the total amount payable, you have the right to voluntary termination - handing the car back and walking away with nothing more to pay, provided the car is in reasonable condition and within any agreed mileage.

If you are deep in negative equity, voluntary termination can sometimes be a cleaner exit than part-exchanging and rolling the shortfall forward, because you are not carrying old debt into a new deal. It is worth checking how much of your agreement you have paid before you decide.

Your exact rights depend on your individual agreement - always contact your lender, or refer to your credit agreement, to confirm your voluntary termination rights before acting.

How to part-exchange a financed car, step by step

1. Request your settlement figure from your current lender (it is free, and your legal right).
2. Get at least two realistic valuations of your car, so you know its true part-exchange value.
3. Compare the two and work out whether you are in positive or negative equity.
4. Agree the price of your next car before any part-exchange figure is discussed, so the numbers stay transparent.
5. Let the dealer settle the old finance directly with your lender and set up your next agreement.

One tip: always keep the price of your next car separate from your part-exchange offer. If a dealer only quotes a single "changeover" figure, it is harder to see whether you are getting a fair deal on both sides.
