The UK Supreme Court will hand down its decision on hidden car finance commission mis‑selling on Friday 1 August 2025 at 4.35 pm. Financial expert Martin Lewis has branded the case “monumental,” warning of implications beyond car finance. Drivers who were sold finance without full disclosure of commission could be due thousands in compensation UK‑wide.
This week could change everything for consumers who were unknowingly overcharged in car finance commission mis‑selling in the UK. On Friday 1 August 2025, at 4.35 pm, the UK Supreme Court will deliver its landmark ruling on whether undisclosed broker commissions make car finance agreements unlawful.
Why It Matters
In October 2024, the Court of Appeal ruled that car dealers and brokers must obtain fully informed consent from customers before receiving commission—a ruling that applies to up to 99% of car finance deals pre‑2021 . Now the Supreme Court must confirm or overturn that judgment.
Martin Lewis, founder of MoneySavingExpert.com, wrote on X: “This decision could have ramifications across the economy, far beyond car finance”. He also warned consumers to avoid rushing into claims via firms that could take 30–36% in fees for potentially zero gain.
What’s at Stake?
- Scale: Up to £30–£44 billion in potential compensation through industry-wide redress, comparable to the PPI scandal.
- Redress path: FCA may launch an automatic compensation scheme, contacting eligible customers directly without the need to claim manually.
- Government intervention: Chancellor Rachel Reeves is reportedly considering retrospective legislation to limit payouts—raising concerns about democratic norms and consumer protection.
How Much Compensation Can You Claim?
If the Supreme Court upholds the appeal‑court ruling, compensation will likely cover:
- Overpaid interest due to undisclosed commission.
- Interest on top backdated to the date of the agreement.
- Typical payouts estimated at around £1,000, though some could be higher depending on loan size and interest margin .
Drivers might see:
- £600–£1,100 for personal contract purchase (PCP) or hire‑purchase deals.
- Larger sums for high‑value loans or long‑term agreements.
FCA’s redress scheme is expected to be simple and straightforward, avoiding mandatory use of lawyers or claims firms. That means you could claim yourself for free—and save on fees.
Martin Lewis’ Core Advice
- Don’t rush in and sign up for claims management firms now. At this stage, they may charge up to 30–36% of any compensation and could deliver nothing if automatic payouts are introduced.
- Do register a complaint yourself if you want to create a “marker in the sand.” Use free tools on MoneySavingExpert to check if you had a discretionary commission arrangement (DCA) or non‑DCA commission.
- Wait for FCA guidance—the regulator plans to confirm next steps within six weeks after the ruling.
People Also Ask
1. What is hidden car finance commission mis‑selling?
It refers to cases where the car broker or dealership increased the interest rate or fee margin for commission, without telling the consumer. If not fully disclosed, this practice could be unlawful.
2. Which car finance deals are affected?
Deals from 2007 up until January 2021 are affected—especially PCPs and hire‑purchase agreements where commission was not disclosed or consented to.
3. Am I eligible to claim compensation?
If you took out car finance before January 2021 and the commission wasn’t fully disclosed, yes—you may be eligible. That includes both discretionary commission arrangements (DCAs) and non‑DCA commission mis‑selling.
4. How long does a claim take?
It depends. If there’s an FCA redress scheme, payments could be made automatically within months. For individual complaints via Ombudsman or solicitor, it could take longer—typically weeks to months.
5. Do I need a solicitor or claims firm?
No. You can lodge a claim yourself. If an FCA scheme is introduced, firms may not even accept claims from third parties. And third‑party fees can take up to 30–36% of your refund.
The Broader Context
The FCA banned discretionary commission arrangements (DCAs) in motor finance from January 2021. However, until then, brokers often had discretion to vary interest rates and take more commission—a model the FCA found harmful to consumers in its 2020 review.
In October 2024, the Court of Appeal ruled that non‑disclosure made the commission unlawful. The Supreme Court now has to decide whether to uphold or overturn that judgment.
Banks including Lloyds, Santander, Barclays, Close Brothers, FirstRand, and MotoNovo have already provisioned hundreds of millions in anticipation of payouts—suggesting that the financial sector expects at least some degree of redress .
Meanwhile, consumer advocates, including Martin Lewis, have criticised Chancellor Reeves’ potential plan to override the decision via retrospective legislation, warning it undermines consumer rights and judicial independence.
