What is a DCA Commission in Car Finance Claims?
A Discretionary Commission Arrangement (DCA) is a commission structure where car dealers earn more commission the higher the interest rate they secure — creating a clear conflict of interest that the FCA banned in January 2021.

What is a Discretionary Commission Arrangement?
A Discretionary Commission Arrangement refers to the commission structure where car dealers and finance brokers earn commissions based on the interest rate they secure for a consumer's car loan. The higher the interest rate in the finance deal, the larger the commission earned by the dealer or broker.
This commission is typically a percentage of the overall car loan amount and can significantly impact the total cost of the car loan. Simply put: you pay a higher amount each month for your car, just because the dealer wanted to earn more commission.
How Does It Work?
When a consumer approaches a car dealer for a finance agreement, the dealer collaborates with a finance provider to offer a loan. In many cases, the dealer or broker is incentivised to put the consumer on a higher interest rate because they'll earn a higher commission. This commission can rise significantly — sometimes reaching as high as 20% of the total loan amount.
For example, on a £15,000 car loan, the commission could be as much as £3,000.
Why is This Problematic?
This commission structure creates a clear conflict of interest. Car dealers and brokers are motivated to sell higher interest rate car finance to maximise their earnings — often at the expense of the consumer's financial well-being. Consumers, unaware of this hidden cost, usually end up paying significantly more over the life of the loan.
Regulatory Response
Recognising the potential for consumer detriment, the Financial Conduct Authority (FCA) intervened and banned this practice in January 2021. The FCA's action aimed to protect consumers from inflated interest rates and ensure fairer, more transparent car finance deals.
Impact on Pre-2021 Motor Finance Agreements
For finance agreements made before this ban, many consumers might still be paying higher rates due to these discretionary commission arrangements. Evidence, supported by numerous successful court rulings by Sentinel Legal, indicates widespread use of such practices, leading to significant financial harm to consumers.
