The sudden resignation of Abby Thomas, FOS CEO (Financial Ombudsman Service), has raised serious concerns about the regulator’s ability to handle the growing car finance mis-selling scandal.
Her departure comes just days before she was due to face questioning by MPs, with critics now questioning whether the FOS is structurally capable of processing the wave of consumer complaints expected over car finance mis-selling.
At Sentinel Legal, our investigations over the past four years have uncovered widespread failures in hidden commissions, dealer payments, and regulatory oversight. With 31.7 million finance agreements potentially mis-sold and Moody’s estimating a £30 billion financial impact, consumer redress is at stake.
The FOS’s Role in Car Finance Mis-Selling: System Failure?
The Financial Ombudsman Service (FOS) was designed to handle individual consumer disputes, but the scale of the car finance crisis far exceeds its normal caseload.
🔎 Key concerns around the FOS handling of car finance claims:
Massive backlog expected
The FOS was never structured to handle a mis-selling scandal of this magnitude.
Government revenue model
Critics suggest that deliberate inefficiencies may extend claim timelines, pushing more consumers into FOS’s £250 complaint fee system.
Regulatory confusion
Reports suggest that FCA redress guidance remains vague, allowing lenders to delay or reject claims, forcing them into the overloaded FOS system.
With hundreds of thousands of claims expected, can the FOS handle the financial fallout—or is this another system built to fail?

The Financial Cost: Santander’s 38% Profit Drop & Growing Industry Liabilities.
The car finance mis-selling scandal is already hitting lenders hard, with Santander UK reporting a 38% drop in annual pre-tax profits and setting aside £295 million for potential compensation payouts.
However, the true financial damage is likely far greater. According to Moody’s, the total industry-wide liability could reach £30 billion.
Why Santander is Feeling the Pressure
£14.96 million in advanced commissions – Our investigations found Santander paid £14.96M upfront to a dealer network, tied to a £75M loan commitment—a clear conflict of interest.
£16,049 in hidden commissions – In one £81,509.05 Land Rover finance agreement, we uncovered that 61% of the total cost of credit was hidden commission payments.

Sam Ward, Sentinel Legal Director, on the FOS CEO’s Resignation
"The timing of Abby Thomas’s resignation is highly concerning. The FOS was about to face tough questions on its ability to handle the car finance crisis, and suddenly, its leader steps down. Consumers should be asking, what was she not willing to answer?"
"With Santander already setting aside £295 million and Moody’s predicting £30 billion in total liabilities, the financial impact of car finance mis-selling is only beginning to unfold. If the FOS is unprepared, and the FCA allows vague redress policies, consumers risk being left in limbo while lenders stall payouts."
"At Sentinel Legal, we are prepared to challenge every case, because we already know what the lenders and regulators don’t want you to see."
What This Means for Consumers
If you’ve taken out car finance since 2007, you could be affected. Santander, and many other lenders, have built finance agreements on hidden commissions, inflated interest rates, and undisclosed fees, leaving consumers to pay thousands more than they should have.
