The news: UK drivers who spread their car insurance over monthly payments are being charged a median APR of 26.2%, with some quotes carrying rates above 50%, according to new mystery-shopping results published by consumer group Which? on Tuesday, October 13, 2026. Which? is urging regulators to ban what it calls "two-tier" pricing — charging drivers extra simply for paying monthly — as reported by Particle News on October 13, 2026.
Around 15 million UK motorists use premium finance to spread their car insurance cost instead of paying a lump sum once a year. For them, the investigation suggests, the true cost of their policy can be hundreds of pounds more than the headline price.

What Which? found, in numbers
- Median APR of 26.2% across 36 premium-finance quotes tested in Which?'s mystery shopping — meaning a typical monthly payer is effectively borrowing at a rate far above most credit cards.
- Some quotes carried APRs above 50%, pushing the cost of paying monthly into genuinely expensive borrowing territory.
- Around 15 million UK motorists use pay-monthly premium finance to spread the cost of car insurance rather than pay an annual lump sum.
- Hundreds of pounds in extra cost: Which? says the gap in monthly finance costs can add hundreds of pounds to policies, hitting drivers who can least afford a lump sum hardest.
- Two demands: Which? is urging regulators to ban "two-tier" pricing that charges extra for monthly payments, and to require firms to offer a pay-monthly option — so cheaper payers can't simply be shut out of monthly plans.
- No regulatory change yet: at the time of writing, no regulatory change has been announced in response to Which?'s call.
The findings landed in the same month that overall UK motor premiums turned upward year-on-year for the first time since 2023 — we covered that shift in our UK car insurance price rise guide. For the 15 million monthly payers, the finance cost sits on top of those rising base premiums.
How pay-monthly premium finance works
When you choose to pay car insurance monthly in the UK, you're not usually just paying in instalments — you're taking out a credit agreement with a premium finance company (often a partner of your insurer). Here's the mechanics:
- You pay a deposit — typically around 10–20% of the annual premium — and the finance company pays the full annual premium to your insurer up front.
- You repay over the year — usually 10–11 monthly payments covering the rest, plus interest.
- The interest is the APR you see quoted — that's the annual rate you're charged on the credit. The gap between the "annual price" and the total of your monthly payments is the premium finance charge.
"Two-tier" pricing is the second layer: even before interest, some insurers simply price monthly payers differently. Which?'s argument is that this creates two classes of customer — those who can afford a lump sum and pay the advertised price, and those who can't and pay more twice over.
Why Which? says two-tier pricing is unfair
The core of Which?'s case is the poverty premium: the people most likely to pay monthly are the people least able to afford the annual lump sum — younger drivers, lower earners, and those with tighter cash flow. Charging them the highest effective borrowing rates concentrates the cost on the drivers who can least bear it.
Which?'s two demands follow directly:
- Ban two-tier pricing — stop charging drivers extra simply for the act of paying monthly, so the monthly option isn't systematically the expensive option.
- Require firms to offer a pay-monthly option — prevent insurers from sidestepping the ban by dropping monthly payments altogether, which would lock out the 15 million motorists who depend on them.
Consumer groups have raised premium-finance costs before, but Which?'s mystery-shopping numbers — a 26.2% median and some quotes over 50% — put hard figures on a practice many drivers barely notice, since the APR is typically buried in renewal paperwork.
What the insurance industry says
Industry groups pushed back. The Association of British Insurers (ABI) and Biba (the British Insurance Brokers' Association) defended monthly payment options as preserving access to insurance for drivers who can't pay a lump sum, arguing the extra costs reflect administration and risk and that APRs should be fair and transparent.
Insurers also pointed to the pressure behind rising premiums generally: surging claims costs, including about £108 million from e-bike and e-scooter claims to May 2026, are helping to drive base premiums higher for everyone — the context behind the wider market turnaround covered in our October premiums article.
No regulatory change has been announced since Which?'s call. The Financial Conduct Authority has previously looked at premium finance costs, so this may be the start of a longer process rather than an overnight rule change.
What it means for you
If you pay your car insurance monthly, three things follow from Which?'s findings:
- Check your actual APR. Your finance company's rate is on your credit agreement or renewal documents — many drivers never look. Compare it with the 26.2% median: you could be paying much more.
- Do the pound-difference maths. Add up your deposit plus all monthly payments, subtract the annual price, and that's your true premium-finance cost. On a policy in the £500–£1,000 range, a 26%+ APR can easily mean £80–£150+ extra per year.
- Don't assume the headline price is what you're paying. Comparison sites usually show the annual price; the monthly total can differ by insurer, and some providers that look cheap annually may be expensive monthly.
Younger drivers are disproportionately affected — they pay the highest premiums, making the lump sum hardest to find, and the highest median rates. If that's you, our guide to cheap car insurance for young drivers in the UK covers the strategies that actually bring premiums down.
What to do before your next renewal
- Get the annual AND monthly price from every insurer you compare. Rankings can change once the finance cost is included — an insurer that's cheapest annually isn't always cheapest monthly.
- Ask the insurer for the exact APR and total credit cost before you commit to a monthly plan. It's a regulated credit product: they must tell you.
- Consider a 0% money-transfer or purchase credit card to pay the annual premium in one go, then pay the card off monthly. If you can clear the balance within the 0% period, you get the annual price without the premium-finance markup — but be disciplined: missed payments bring their own high interest.
- Time your purchase. Buying around 3–4 weeks before your start date is typically cheaper than last-minute renewal, and the finance charge is calculated on the premium — a lower base price means a lower monthly total too.
- Build toward annual payment. If you can overpay or save a small amount each month into a separate pot, you may be able to pay annually next year — the single cheapest way to avoid the two-tier penalty while it still exists.
- Never auto-renew. With Which?'s findings in the news, some insurers may quietly sharpen their monthly offers — but only if you make them compete.

Frequently asked questions
Is paying car insurance monthly really a loan?
Usually, yes. Most UK "pay monthly" insurance plans are premium-finance credit agreements: a finance company pays your insurer the annual premium up front, and you repay it with interest over the year. That's why there's an APR, a deposit, and regulated credit terms.
What APR should I consider too high?
There's no official cutoff, but Which?'s 26.2% median is far above typical personal-loan and many credit-card rates. Any APR in the 25%+ range deserves a hard look at alternatives like a 0% credit card; anything above 50% — which Which? found in some quotes — is exceptionally expensive borrowing.
Will regulators actually ban two-tier pricing?
Not yet — no regulatory change has been announced since Which?'s call. The FCA has examined premium finance costs in the past, so scrutiny is likely to continue, but a ban would require a formal regulatory process. Don't wait for the rules to change: act on your next renewal.
Where can I verify these figures?
The investigation is Which?'s mystery-shopping research published October 13, 2026, as reported by Particle News on October 13, 2026 — median APR 26.2% across 36 quotes, some above 50%, with industry response from the ABI and Biba.
