Nearly a Third of Car Finance Trade-Ins Are Now Underwater, Data Shows

Nearly One in Three Trade-Ins Are Underwater

Settlement figures compared against trade-in values by Cap HPI and the Finance and Leasing Association point to roughly 30 percent of new-vehicle HP and PCP trade-ins carrying negative equity in early 2026, the worst reading in five years, dating back to the supply shortages of 2021 that pushed used values in the opposite direction. Negative equity means the amount still owed on the finance agreement is higher than what the car is actually worth on the day it goes back to a dealer, and for three in ten drivers changing cars this year, that gap is now standard rather than exceptional.

The trap catches drivers precisely where a PCP agreement is built to make monthly payments look affordable, not to track the car’s real value. Payments cover expected depreciation and interest, weighted toward interest in the early months, while the balance owed falls slowly. Depreciation moves faster in the opposite direction in the first 12 to 18 months of ownership, which is exactly when many drivers are tempted back into a dealership by a new model or a manufacturer incentive on the next car up the range.

How the Shortfall Gets Hidden Inside a New Deal

A driver who owes more than their car is worth has three options at renewal: pay the shortfall in cash, keep the current car and carry on paying, or roll the negative equity into a new finance agreement. Dealers routinely offer the third option. It keeps a customer in a showroom and moving to a newer car, and it turns an uncomfortable conversation about a shortfall into a single, larger number folded quietly into a new loan.

Rolling negative equity into a new PCP increases both the total amount borrowed and, in many cases, the interest rate applied, as a lender pricing risk on a higher loan-to-value deal treats the customer differently from one starting fresh. A driver who was £1,500 underwater on their last car can find that debt quietly added to the balance of their next agreement, then compounding again if they repeat the cycle at the next renewal. Dealership finance teams are not required to flag how much of a new monthly payment is covering old debt rather than the car actually being driven off the forecourt that day, and few volunteer the breakdown unless a customer asks directly.

The Consumer Right Most Drivers Have Never Used

Buried inside the Consumer Credit Act is a protection that could stop the rolling debt cycle before it starts: voluntary termination. Once a driver has paid 50 percent of the total amount payable under a regulated PCP or HP agreement, including any deposit, they can hand the car back and owe nothing further, regardless of how much negative equity exists on paper. On a PCP specifically, the 50 percent threshold is calculated against the total amount payable including the balloon payment, which pushes the qualifying point later into the agreement than most drivers expect, but the right applies all the same once that threshold is reached.

Few drivers use it. Few are ever told about it in the first place. A driver sitting in a dealership being offered a plain trade-in and a new agreement is rarely handed a comparison showing what walking away under voluntary termination would cost instead, even when they have already crossed the 50 percent mark and termination would leave them with nothing more to pay. The right exists in law regardless of what a dealership finance team chooses to mention.

What This Costs a Driver Who Gets It Wrong

A driver who rolls £2,000 of negative equity into a new four-year PCP at a typical APR is not just paying back £2,000. They are paying interest on that £2,000 for the full new term, on top of interest on the new car’s own finance, while their monthly payment rises to reflect the larger balance. Repeat the pattern at the next renewal and the debt carried forward compounds again, even as the driver believes they are simply moving to a newer model every few years rather than building a growing balance that never quite clears.

Younger and lower-income buyers carry more of this risk than most. They are more likely to put down a smaller deposit and borrow a higher proportion of a car’s value from the outset, which leaves less room to absorb a depreciation shock in the first 18 months of the agreement.

Why Dealers Have No Incentive to Warn You

A dealer’s finance income does not come primarily from the price of the car. It comes from commission on the loan itself, paid by the lender, plus any add-on products sold alongside it. A deal that rolls negative equity into a bigger loan generates a bigger commission than a deal that sends a customer away to settle a shortfall in cash and think it over. None of this is illegal or even unusual in the industry, but it means the person explaining your options at the point of sale is paid more when you choose the option that leaves you carrying more debt.

Financial Conduct Authority rules require lenders to assess affordability before approving an agreement, but affordability is judged against the new monthly payment a driver can meet, not against how much of that payment is servicing debt from a car already handed back. A driver can pass an affordability check while still being worse off than if they had simply paid down the shortfall directly.

How to Fight Back

• Before visiting a dealership to change your car, get your current settlement figure directly from your finance provider and compare it against an independent trade-in valuation, not the dealer’s own offer, to see the real size of any shortfall.
• Check how much of the total amount payable on your current agreement you have already paid, including your deposit. If you have passed 50 percent, ask your finance provider directly about voluntary termination rather than accepting a trade-in offer that rolls debt forward.
• If a shortfall exists and you cannot avoid it, ask whether paying it off in cash is possible before signing a new agreement, as even a partial cash payment reduces the interest charged over the new term.
• Ask the dealer’s finance team, in writing, to state clearly how much of any new monthly payment is covering negative equity carried from the previous car versus the new vehicle. You are entitled to a clear breakdown before signing anything.
• Avoid extending a PCP term, for example moving from 36 to 48 months, purely to make a payment including rolled-over debt look smaller, as a longer term increases the total interest paid over the life of the agreement.

Why the Problem Is Bigger Than One Bad Deal

A single driver rolling one shortfall into one new agreement is a personal finance problem. Thirty percent of the market doing the same thing at every renewal cycle is a structural feature of how new cars are now sold in Britain, where list prices have risen faster than take-home pay and PCP became the default way to make a new car look affordable on a monthly basis rather than an occasional financing choice among several. Every renewal that rolls a shortfall forward also props up new car sales volumes that might otherwise fall if buyers were forced to reckon with the full cost of their current agreement before signing another one.

What Happens Next

Negative equity on this scale is a symptom of a used car market still adjusting after the 2021 to 2023 price spike unwound, combined with new car prices that have kept monthly PCP payments high enough that drivers borrow close to the maximum against a depreciating asset. Unless a driver actively checks their settlement figure against real trade-in value before every renewal, and understands the voluntary termination right sitting inside their own contract, the current 30 percent negative equity rate has little reason to fall on its own, and each renewal cycle risks leaving another wave of drivers carrying debt from a car they no longer own into the payments on the one they drive next.
