The recent Supreme Court judgement on car finance commissions has stirred interest and concern among millions of UK motorists. With headlines about possible compensation claims and the scale of impact, many are wondering how the decision affects their own car loans and the broader automotive sector.
The Background: Car Finance and Hidden Commissions
For years, car dealers have acted as intermediaries for car finance deals. Most motorists buying a new or used car opt for Personal Contract Purchase (PCP), hire purchase, or other forms of finance offered directly through dealerships. In the vast majority of these arrangements close to 99 percent a commission is paid by the lender to the dealer for securing the finance agreement.
The controversy stemmed from the fact that these commissions were often undisclosed or not made clear enough to customers. The more a customer paid in interest, the higher the commission the dealer received, creating a potential conflict of interest. The Financial Conduct Authority (FCA) banned such “discretionary commission” arrangements in January 2021, citing concerns over transparency and fairness.
The Legal Challenge: Why the Supreme Court Was Involved
The issue reached a head when three motorists brought separate claims against finance companies after discovering that the car dealers received commissions on their loans, something they say was never properly disclosed. A Court of Appeal ruling in 2024 found in favour of the consumers, declaring that “secret” commission payments were unlawful and ordering finance companies to compensate the drivers.
This result sent shockwaves through the industry, raising the spectre of payouts amounting to as much as £45 billion—potentially reminiscent of the Payment Protection Insurance (PPI) scandal. Lenders and dealers appealed, and the matter proceeded to the UK Supreme Court, which delivered its decision in August 2025.
The Supreme Court Judgement: What Was Decided?
The Supreme Court reversed the earlier ruling, deciding that lenders are not, in most cases, liable for hidden commission payments in car finance schemes. The court found that:
Car dealers arranging finance do not usually owe a “fiduciary duty” (a special relationship of trust) to customers arranging loans.
The mere existence of an undisclosed commission does not automatically make the contract between borrower and lender “unfair”.
Compensation may be available only in cases where particularly high commissions made the finance relationship clearly unfair under the Consumer Credit Act.
As Lord Reed, President of the Supreme Court, explained, while disclosure is important, the arrangements do not by default give rise to a legal obligation for dealers to act solely in the interest of their customers. The court also confirmed that not every customer with a commission-based car finance agreement would be due compensation, significantly reducing the number of viable claims against lenders.
What Does This Mean for Drivers?
Millions who hoped for widespread redress have been denied automatic compensation. Only a small proportion of cases where the commission was exceptionally large or the terms egregiously unfair may still qualify for repayments. One claimant in the test cases did receive a compensation payment of just over £1,650, a relatively modest sum compared to the vast claims some had predicted.
Experts now estimate the total compensation payouts will fall between £5 billion and £15 billion, well below the £45 billion worst-case scenario that lenders once feared. This outcome also avoids the economic disruption and pressure on UK banks that a higher bill might have caused.
Financial consumer campaigner Martin Lewis urged motorists not to rush into signing up with claims management firms. He suggested waiting for further guidance from the FCA, which is expected to set out details of any redress scheme within weeks. Lewis advised that some compensation—if due—could be paid automatically, without the need for lengthy claims processes.
Official Responses and Industry Impact
The government welcomed the clarity the judgement brings, and the Treasury issued a statement confirming respect for the court’s decision. Officials highlighted that reforms were already underway to the Financial Ombudsman Service and the Consumer Credit Act to ensure fairness and clarity in financial products1.
The ruling has further implications for the automotive and lending industries. While banks and finance companies have avoided an “Armageddon” scenario, the case has prompted major lenders to put aside billions in contingency funds. The FCA and car finance industry continue to review sales practices and historical agreements to identify any unfairness needing further action.
On the stock market, UK bank shares rose following the judgement, reflecting relief that the immediate financial threat has diminished. Nonetheless, car finance providers remain under scrutiny to ensure they act transparently, treating customers fairly and only recommending products that suit individual circumstances.
Consumer Watch: Could More Cases Arise?
Some consumer rights groups argue that the Supreme Court’s ruling still leaves doors open for particular cases under the Consumer Credit Act. If drivers suspect that their finance deal involved excessive commissions or unfair terms, they may still be eligible to make a claim. Legal experts advise reviewing old agreements, especially those made before the FCA’s 2021 ban on discretionary commissions.
The FCA has indicated it will consult on a redress scheme and provide detailed guidance soon. The vast majority of British drivers, however, should not expect automatic payouts or to see a repeat of the PPI redress bonanza.
Looking Ahead: Lessons for Lenders and Consumers
The Supreme Court decision draws a line under a period of uncertainty for the motoring public and financial sector. It reinforces the principle that transparency matters and that both lenders and intermediaries must treat customers with honesty and fairness. It also serves as a reminder to always ask questions and read finance agreements carefully before signing on the dotted line.
As the dust settles, the industry, regulators, and consumers will watch closely for the FCA’s next steps. For now, the message is clear: not all commission-based car finance deals were unlawful, but vigilance and transparent advice should be the standard for every motorist in the UK.
