UK Car Insurance Prices Rise Year-on-Year for the First Time Since 2023: What Drivers Should Do

The news: UK motor insurance premiums have ended a quarter 2.7% higher than a year earlier — the first annual increase since 2023, ending two years of falling prices. The figures come from the latest Defaqto Market Pricing Motor Insurance Price Index, reported by Insurance Business on October 10, 2026.

The headline hides a sharply divided market: prices fell 1% in London but jumped 16.3% in Northern Ireland, the largest regional increase. Here's what the turning point means and how to respond before your next renewal.

The turning point, in numbers

• Annual change: competitive quoted premiums were 2.7% higher at the end of September than a year before, per Defaqto — the first positive annual comparison since 2023.
• Quarterly change: prices rose 0.5% in the third quarter, cooling from 2.1% in the second quarter. July rose 0.4%, August 0.2%, and September slipped 0.1%.
• Longer view: premiums are still 12.8% below where they stood two years ago, though 11.9% above the start of 2020.
• Provider spread: individual insurers' Q3 price movements ranged from a 3.5% cut to a 9.6% increase.

"The annual comparison has turned positive, but the latest quarterly figures suggest a market finding a more stable footing," said Stephen Kennedy, director at Defaqto. The flattening quarterly trend suggests the market is stabilising rather than swinging into a hard, across-the-board price surge.

Why prices are turning: record claims payouts

The reversal follows sustained claims inflation. The Association of British Insurers (ABI) says motor insurers paid out a record £3.2 billion in claims in the second quarter, with the average claim up 4% to £4,900 — while average premiums paid rose by just £6.

In plain terms: insurers have been paying out much more while charging only slightly more, and that gap eventually forces prices up. Rising repair costs — driven by advanced vehicle technology and more expensive replacement parts — are pushing claim values higher even as the number of claims stays broadly steady.

Winners and losers: where prices rose most

The market-wide figure is modest, but the movement underneath varies widely by provider, age band, and region, according to Defaqto:

• By region: the gap is the most striking finding. Prices fell 1% in London but rose 16.3% in Northern Ireland, the largest increase of any UK region. Northern Ireland was also the only region where average premiums did not fall in Q3, with costs for young drivers there overtaking London.
• By age: older drivers saw the largest increases over the past year, while competitive prices for drivers under 26 and those aged 26 to 30 remained below last year's levels.
• By mileage: drivers covering fewer miles saw larger increases — counterintuitive, but low-mileage policies are being repriced as insurers refine risk models.

Separate price comparison data this month showed a sting for young drivers in particular: Quotezone's Q3 2026 Car Insurance Price Index, reported by Grimsby Live, puts the median UK premium at £587.35 (down £31.66 in three months), but the median for drivers aged 17 to 24 rose £50.77 in three months to £1,150.34.

What it means for your next renewal

If your renewal is due in the next few months, expect two things. First, after two years of falling prices, the psychological shock: quotes that look higher than last year's even if you've been claim-free. Second, a widening spread between insurers — with individual providers moving anywhere from −3.5% to +9.6% in a single quarter, the gap between the cheapest and most expensive quotes for the same driver is growing.

That spread is actually good news for proactive shoppers. When every insurer moves in lockstep, shopping around yields little. When providers diverge, comparing quotes can uncover meaningful savings — particularly for older drivers, lower-mileage motorists, and anyone in Northern Ireland, the groups seeing the largest rises. Francis Luery, product manager at Defaqto, noted that motorists will experience the return to annual price growth very differently, and that brokers and comparison sites need to understand the movements within the customer groups they serve.

How to push your premium back down

1. Compare at least 5–10 quotes. With providers diverging this sharply, loyalty is expensive. Use two comparison sites plus one or two direct insurers, and never auto-renew.
2. Time your purchase. Buying around 3–4 weeks before your policy starts is typically cheaper than renewing at the last minute, when prices peak.
3. Consider telematics if you're under 30. A black-box policy rewards actual driving behaviour rather than the statistical average of your age band — one of the few levers young drivers control.
4. Raise your voluntary excess carefully. A higher excess lowers the premium, but only pick an amount you could actually pay after a claim.
5. Check your mileage estimate. Low-mileage drivers are seeing bigger increases, so make sure your declared mileage is honest and current — over-declaring miles costs money; under-declaring can void a claim.
6. Review named drivers and policy extras. An experienced named driver can help (for some profiles); strip extras you won't use, like legal cover or courtesy car, if they don't justify the price.
