The Supreme Court will reveal its judgment on hidden car finance commission claims on Friday 1 August at 4.35pm, it's been announced.

The Supreme Court heard the case in April 2025. It came after car finance firms Close Brothers and Motonovo appealed against a surprise Court of Appeal ruling, made in October 2024, that all car finance agreements with hidden commission were unlawful.

Here's Martin's explainer of what the Supreme Court's doing and what you need to know now.

Martin Lewis: 'This decision could have ramifications across the economy, far beyond car finance'

News. CAR FINANCE SUPREME COURT RULING TO COME 4.35PM FRI 1 AUG. This decision could have ramifications across the economy, far beyond car finance. I suspect that's why the Supreme Court has announced it's working on it till the last possible minute to get this out before its 'term closes' (that and doing it once markets close).

So I want to speedily to bash out a rough explanation of what's happening.

There are TWO types of car finance mis-selling cases and while the Supreme Court is only looking at one, both are on hold until the judgment is handed down.

1. Discretionary commission arrangements (DCAs). This applies to about 40% of car finance deals, and is where brokers and dealers could increase the amount of interest they charged customers (without telling them) on Personal Contract Purchase (PCP) and hire purchase agreements up to 2021. If they did so, they got increased commission. This was obviously problematic.

  • This is NOT the case the court is deciding.

  • If you've heard me talking about Car Finance reclaiming, this is the type I've focused on (my site has had over 3 million reclaim template emails sent).

  • For the bulk numbers this isn't primarily about court action, but the regulator – the Financial Conduct Authority (FCA) – looking at redress for mis-selling, it has even said it may potentially do it without people needing to reclaim; it may order firms to do automatic paybacks. The FCA says it will announce its next steps six weeks after the Court ruling.

  • So overall, on balance this is still likely to go ahead regardless of the Supreme Court ruling (unless it throws out an absolute wobbler – nothing is impossible!).

2. Commission disclosure complaints. This is the one the Supreme Court is deciding on.

Last year, the Court of Appeal shocked many people, the regulator, the lending industry, politicians (and me) by ruling that if car finance agreements didn't tell consumers all details of commission, including the amount (they rarely did), they were unlawful. This applies to up to 99% of car finance (so all those with DCA cases as well).

If the Supreme Court doesn't overturn the Court of Appeal decision, the knock-on effects could be substantial on other forms of lending and the economy. It could shake the foundations of consumer lending (meaning less possible available credit for many).

So much so, I have long said I worry it may do more harm than good for consumers. It's therefore unsurprising there's talk of the Chancellor overruling the decision if the Supreme Court follows the Court of Appeal [such as in this article in The Guardian].

So in summary, three things could happen...

  1. Supreme Court upholds Court of Appeal ruling. This shakes everything up in the air and there may be political intervention. If not, then most people who've had car finance may be due payouts, but we don't know how big. It could see other similar cases come forward too.

  2. Supreme Court rejects Court of Appeal ruling. In which case it's still likely DCA claims will go ahead via the regulator, but Commission Agreement claims will stop.

  3. Supreme Court comes up with something novel...

As for what to do now... wait until the result.

Beware car finance reclaiming ads

While we await the outcome of the Supreme Court case, be very careful about any car finance reclaiming adverts you see.

As Martin has warned, signing up to a claims management firm or law firm could mean you end up giving away 30% of what you're owed and getting nothing in return if automatic payouts are introduced.

The regulator itself has said: "Consumers should be aware that by signing up now with a CMC or law firm, they may end up paying for a service they do not need and having to pay up to 30% in fees out of any award they may receive."

Instead, the best thing to do at this point is just wait and see what happens.

Car finance mis-selling – a brief timeline

Discretionary commission arrangements (DCAs)

Commission disclosure complaints

January 2024: FCA launches huge investigation into DCAs, which allowed brokers and dealers to choose from a range of interest rates, and to earn more commission if they charged a higher one. Car finance firms are told to pause dealing with complaints about these arrangements.

Since then, over 3 million DCA complaints have been made via our free tool.

October 2024: Landmark Court of Appeal verdict rules that car sales firms couldn't lawfully receive commission from finance firms unless they had the customer's "fully informed consent" – in effect creating a new category of 'commission disclosure' mis-selling complaint.

The car finance firms involved – Close Brothers and Motonovo – appeal this judgment to the Supreme Court.

December 2024: FCA extends pause on firms dealing with car finance complaints to all commission complaints – not just DCAs as was previously the case.

It means car finance providers do not have to provide final responses to motor finance non-DCA commission complaints received on or after 26 October 2024 until after 4 December 2025.

March 2025: FCA confirms that it will consult on a redress scheme, and will announce the next steps for complaints six weeks after the Supreme Court makes its decision on the commission disclosure case.

April 2025: Supreme Court hears appeal against the October 2024 ruling.

The Supreme Court will deliver its judgment on Friday 1 August.
