In February 2026 the Financial Conduct Authority published the final report of its premium finance market study, and one figure in it should stop you paying your car insurance monthly without checking the small print: almost one in five people who spread their premium are being charged an interest rate above 30 per cent. That is the number I keep coming back to, because paying monthly feels like the responsible thing to do, and for a fifth of drivers it is quietly the most expensive way to insure a car. Here is what the regulator found, and the letter I would send before my own renewal lands.
The rate you are probably paying to pay monthly
According to the FCA’s February 2026 findings, around 60 per cent of consumers pay a headline APR of between 20 and 30 per cent to spread an insurance premium, and almost one in five pay more than 30 per cent. On an illustrative motor policy of about £400, that 20 to 30 per cent band adds roughly £35 to £51 over the year. None of these figures is a quote for your policy; your own rate will depend on your insurer and circumstances, and the only number that counts is the APR printed on your renewal.
The good news the insurers will not lead with
It is not all bad, and I will give credit where it is due. The FCA’s review of premium finance found that more than half the firms it looked at had lowered the cost, that rates have fallen by an average of 4.1 percentage points since 2022, and that consumers are saving around £157 million a year as a result. The full market study report, MS24/2, lays out the detail. The regulator stopped short of capping APRs, which means the responsibility to check still sits with you.
Why monthly is sold as convenience and priced as credit
Here is the practice I want named: paying monthly is presented at checkout as a simple lifestyle choice, a tickbox next to paying annually, when it is in fact a credit agreement with an APR like any other. The convenience is real and for some households spreading the cost is a genuine necessity, not a mistake. What is not acceptable is burying a 30-per-cent-plus rate behind soft language about “easy monthly payments”. If your renewal does not show the APR plainly, that is your cue to ask.
The letter I’d send before renewal
- Ask for the annual price in writing. “Please confirm the total annual premium if paid in one payment, and the total payable if paid monthly, including the APR.” The gap between those two numbers is the cost of the credit.
- Check a 0 per cent card against the finance APR. If your insurer’s APR is north of 20 per cent, a fee-free purchase card cleared within the interest-free window can be cheaper, provided you can clear it.
- Shop the annual price, not the monthly one. Comparison sites default to monthly; switch to annual to see the true cost.
- Keep the renewal letter. It is your evidence if the APR was never made clear.
What I’d do, and the right it rests on
If I could afford the annual premium, I would pay it annually and keep the 20-to-30-per-cent credit cost in my pocket. If I could not, I would treat the monthly option as the loan it is, demand the APR up front, and compare it against a 0 per cent card before signing. The driver this protects is anyone who has clicked “pay monthly” out of habit. Under the Consumer Duty the FCA has put on firms, you are entitled to information that lets you understand the deal and decide with confidence, so a renewal that hides the APR is not just annoying, it falls short of what your insurer owes you.
