UK Supreme Court ruling is set to deliver a landmark decision that could impact millions of motorists and reshape the car finance industry. At stake is whether undisclosed commissions paid by lenders to car dealers were unlawful, potentially opening the door to tens of billions of pounds in compensation.
Consumer Voice, an independent advocacy group, has urged judges to uphold the Court of Appeal’s ruling, arguing the secrecy behind these payments represents a major breach of consumer trust.
In this blog, we break down what’s at stake in the UK Supreme Court ruling, why it matters, and how it may impact your finances, especially if you’ve ever bought a car on finance in the UK.
What the Case Is About
A Legal Turning Point for Consumer Protection
At the heart of the case is a legal question: Did car dealers who received commission payments from lenders without disclosing them to customers breach their fiduciary duty? And if so, can lenders be held responsible for enabling these “secret profits”?
In 2024, the Court of Appeal ruled that the practice of dealers receiving undisclosed commissions was unlawful, especially if they acted as credit brokers rather than independent sellers. That ruling set the stage for a potentially massive consumer redress scheme. The Supreme Court’s decision, expected on 1 August 2025 at 4:35 PM, will either uphold or overturn that ruling.

| Year 1 | 1,100 | 1,900 | 3,000 |
| Year 2 | 900 | 2,100 | 3,000 |
| Year 3 | 700 | 2,300 | 3,000 |
| Year 4 | 500 | 2,500 | 3,000 |
| Year 5 | 300 | 2,700 | 3,000 |
Why This Matters: Billions in Potential Payouts
UK Drivers Could Be Owed Compensation
Over 90% of new cars in the UK are bought on finance. If the Court upholds the earlier ruling, millions of customers could be eligible for compensation some for thousands of pounds in excess interest charges.
Major lenders like Lloyds Banking Group have already set aside more than £1 billion in anticipation of the ruling.
According to Consumer Voice research:
65% of customers trusted their dealer to offer the best finance deal.
75% would have asked more questions or walked away if they knew about commissions.
Only 4% explored alternative finance options before accepting the dealer’s offer.
What Were Discretionary Commission Arrangements (DCAs)?
Before being banned by the Financial Conduct Authority (FCA) in 2021, DCAs allowed dealers to earn more money if they charged customers higher interest rates. These types of commissions gave dealers a financial incentive to push more expensive deals, not necessarily better ones for the customer.
But this case goes even further. It asks whether any form of undisclosed commission, even those not tied to interest rate manipulation, is a breach of consumer trust.
Common Commission Types at Issue:
- Volume bonuses
- Advance payments
- Rights of first refusal
All of these were rarely disclosed to customers.
Expert Insight: Consumer Voice on the Ruling
Alex Neill, co-founder of Consumer Voice, has called for full transparency and fair compensation:
Millions of people trusted their dealer to help them get a fair deal, but were sold loans without knowing the dealer stood to gain. That’s not just unfair, it’s exploitative and illegal.
Consumer Voice applied to intervene in the Supreme Court appeal to advocate for consumer rights. Their data-backed stance is rooted in legal precedent, fairness, and systemic industry failures.
Real Stories Behind the Numbers
Case Study 1: Jemma Caffrey, Blackburn
After returning from maternity leave in 2009, Jemma urgently needed a car. She accepted a high-interest deal on a Vauxhall Corsa, unaware that her dealer received a hidden commission. She only discovered this years later and is now part of a legal case awaiting the Court’s decision.
Case Study 2: Marcus Johnson, Cwmbran
In 2017, Marcus bought his first car, a Suzuki Swift. He had no idea the lender was paying his dealer. Although he signed documents, he says the commission was never explained. His case is one of the three test cases before the Supreme Court.
What Could Happen: 3 Possible Outcomes
1. Appeal Dismissed
If the Supreme Court upholds the ruling:
Lenders and dealers may owe tens of billions in compensation.
The FCA is expected to roll out a formal redress scheme under Section 404.
Both DCA and non-DCA commission arrangements would likely be included.
2. Partial Dismissal
A compromise decision may limit redress to the most harmful commission schemes (e.g., DCA or fully undisclosed deals). Non-DCA victims might still claim, but through more complex processes.
3. Appeal Allowed
If the Supreme Court overturns the ruling:
Compensation will be rare and based on individual lawsuits.
Only banned DCA arrangements would qualify for redress via the FCA.
Consumer trust in the justice system may erode.
Potential Government Interference
According to reports from The Guardian and others, the Treasury is considering retrospective legislation to limit mass compensation should the Court rule in favour of consumers.
Consumer Voice strongly opposes this:
Any attempt by ministers to interfere in the outcome of this case would result in a double injustice to consumers and undermine the independence of the judiciary.
Such a move would be controversial and could harm the UK’s reputation for consumer protection and legal integrity.
What This Means for You
If you took out a car finance agreement before 2021, especially from dealers affiliated with MotoNovo, Close Brothers, or other panel lenders, you may be eligible for compensation.
Even if you are unsure whether a commission was involved, you should:
- Request a copy of your original finance agreement.
- Ask your lender directly if your dealer was paid a commission.
- Use a claim tool or advocacy group like Consumer Voice.

What the Industry Is Saying
The Finance and Leasing Association insists the sector acted lawfully and wants permanent clarity from the Supreme Court.
But critics argue that fairness must take precedence. Stuart Masson, editor of The Car Expert UK, warns that while payouts may increase future lending costs, transparency is critical:
Good regulation builds consumer confidence. That’s the best thing we can do for the economy.
Conclusion: A Defining Moment for Fair Finance
This Supreme Court ruling will not just determine legal liability; it will send a message about transparency, fairness, and consumer protection in the UK.
Whether you’ve already received car finance or are planning to in the future, the outcome could affect your wallet, your rights, and how much trust you place in lenders and dealers.
