How to Claim Secret Commission on Car Finance in the UK

If you purchased a vehicle using credit in the United Kingdom, your dealership or broker may have pocketed an undisclosed commission from the finance company that inflated your repayments. Under the Consumer Credit Act 1974 and landmark appellate case law, hidden dealer kickbacks can create an actionable unfair relationship or an unlawful secret profit. This guide explains how to gather your loan documentation, confront your lender, and seek financial restitution.

What the Law Says in the United Kingdom

In the United Kingdom, consumer motor finance agreements are governed by the Consumer Credit Act 1974 and regulated under the Financial Conduct Authority (FCA) Consumer Credit Sourcebook (CONC). For years, lenders routinely paid motor dealers undisclosed commissions—frequently through Discretionary Commission Arrangements (DCAs)—where the dealer had financial incentive to set a higher interest rate for the customer to boost their own payout.

Under sections 140A to 140C of the Consumer Credit Act 1974, a court can declare a credit relationship unfair if the lender or intermediary fails to disclose material facts, including the existence or size of commissions. This principle was firmly established in the Supreme Court authority of Plevin v Paragon Personal Finance Ltd [2014] UKSC 61 and reinforced in Wood v Commercial First Business Ltd [2021] EWCA Civ 471, which established that paying a secret commission to a broker who owes a duty of impartiality can amount to an unlawful payment.

The Court of Appeal's landmark ruling in Johnson v FirstRand Bank Ltd [2024] EWCA Civ 1282 further clarified that car dealers acting as credit brokers owe a disinterested duty to consumers. Merely hiding a vague statement in standard terms suggesting a commission 'may' be paid is insufficient to negate secrecy or demonstrate fully informed consumer consent. Where an undisclosed or insufficiently disclosed commission was paid, consumers have direct legal grounds to challenge the lender for repayment of the commission, interest rate adjustments, and statutory interest.

How Lenders and Dealers Concealed Commission

Car dealers often present themselves as trusted advisors helping buyers secure the most affordable financing option. In reality, finance providers set up contractual arrangements that rewarded dealerships for steering customers into costlier hire-purchase (HP) or personal contract purchase (PCP) agreements.

Under a discretionary commission structure, the lender set a minimum interest rate and allowed the dealership to increase that rate at will, sharing the extra interest profits with the dealer. Even outside discretionary models, fixed-percentage or volume-based commissions were routinely withheld from borrowers. Burying brief disclosure statements in small-print dealer terms does not satisfy the legal requirement for clear, prominent, and fully informed consent prior to entering into the contract.

Challenging the Lender and Exercising Your Rights

Your legal remedy lies primarily against the finance company that underwrote the agreement, rather than the individual dealership that arranged it. You can demand full disclosure of all commissions paid, request a complete refund of the commission amount plus interest, and ask for a recalculation of your loan balance under sections 140A and 140B of the Consumer Credit Act 1974.

Lenders frequently attempt to stall claims by issuing standard acknowledgment letters or citing FCA regulatory reviews. However, consumer rights under statutory law and binding court decisions remain enforceable. If your lender refuses to provide disclosure or rejects your complaint, you retain the right to escalate the matter to the Financial Ombudsman Service (FOS) or pursue civil court proceedings under the standard limitation rules of the Limitation Act 1980.

Steps

• Locate your original vehicle finance agreements, including your Hire Purchase (HP) or Personal Contract Purchase (PCP) documentation, dealership invoices, and pre-contract credit information sheets.
• Submit a formal Subject Access Request (SAR) under the Data Protection Act 2018 to the finance company, specifically requesting all internal dealer commission schedules, broker fee agreements, calculation sheets, and correspondence related to your loan.
• Send a formal letter of complaint to the finance company's complaints department asserting an unfair relationship under section 140A of the Consumer Credit Act 1974 and breach of disinterested duty based on Johnson v FirstRand Bank Ltd.
• Demand full disclosure of the commission sum paid to the dealer, an account of profits, repayment of the undisclosed commission plus compensatory interest, and an adjustment of historical interest charges.
• If the lender issues a final response rejecting your claim or fails to provide an adequate remedy, escalate your complaint directly to the Financial Ombudsman Service (FOS) within six months of their final response letter.

Common mistakes

• Signing over 30% to 50% of your payout to an aggressive Claims Management Company (CMC) when you can manage the initial complaint and Financial Ombudsman Service process yourself.
• Assuming you cannot bring a claim simply because your car finance agreement has already ended or the vehicle was returned several years ago.
• Accepting a generic refusal letter from your finance company at face value without demanding written documentary evidence of the exact broker commission terms.
• Directing your complaint exclusively to the car dealer instead of the regulated finance company that underwrote the loan and funded the commission.

Questions people ask

What is considered a 'secret commission' in car finance?

A secret commission occurs when a lender pays a broker or car dealer a financial reward for arranging a consumer credit agreement without disclosing the existence, nature, or precise amount of that payment to the borrower, depriving the consumer of the ability to give informed consent.

Can I claim if my agreement only stated that the dealer 'may' receive a commission?

Yes. Following the Court of Appeal judgment in Johnson v FirstRand Bank Ltd [2024] EWCA Civ 1282, vague boiler-plate language buried in small-print terms stating that a commission 'may' be payable is generally inadequate to establish fully informed consent.

How far back can a car finance commission claim go in the UK?

Under section 5 of the Limitation Act 1980, the standard limitation period is six years from the date of the breach or final payment. However, under section 32 of the Act, if the commission was deliberately concealed from you, the six-year clock may only begin when you discovered, or could with reasonable diligence have discovered, the secret payment.
