A higher premium shouldn’t come without an explanation.

Renewal notices arrive with a new price and very little else. The figure changes; the reasoning doesn’t come with it. So it stays hard to tell whether you’re looking at a market-wide shift, something specific to your policy, or simply the cost of staying put.

  • Why did my premium increase?

  • Is everyone paying more, or just me?

  • Could I get similar cover for less?

Three steps, start to answer.

No long forms and no jargon. Your renewal already holds everything the platform needs to answer the question.

Your premium context

Select a row for detail

  • The market average peaked at £995 a year in late 2023 and has fallen back to around £719, though ONS has it climbing again over the past twelve months. What sits underneath is the cost of settling a claim: the average payout rose from £3,842 to £5,464 between 2020 and 2025, a 42% increase, even as the number of claims fell by 59%. Damage claims more than doubled, up 105%. Fire rose 99% and theft 64%. Newer cars carry technology that needs recalibrating after a repair, so each incident costs more to settle than it used to. A share of your increase reflects that movement rather than anything about your policy.

    ONS series L7JE. Confused.com and WTW car insurance price index, Q2 2026.

  • Your vehicle details are the same as last year. Repair and parts costs for this vehicle group have risen, and insurers commonly reflect that in pricing even when nothing about your car has changed.

  • Your address has not changed. Claim frequency in a postcode area still moves year to year, and insurers reprice areas independently, so a stable address can carry a different rate.

  • You reported 3,000 additional miles a year. More time on the road generally means more exposure, though how much weight an insurer gives it varies considerably.

  • No change here, and your no-claims discount still applies. This is one of the factors working in your favour, worth protecting when you compare alternatives.

  • A lower voluntary excess moves more of the risk to the insurer, which typically raises the premium. This is one of the few levers you control directly at renewal.

Market figures: Office for National Statistics, CPI motor vehicle insurance (series L7JE), and the Confused.com and WTW car insurance price index, Q2 2026. The premium breakdown above is an example of what the analysis produces, not a real customer.

Some of it is the market.

Car insurance rose 53% in the twelve months to July 2023, peaked that December, then fell back for two years. Over the past year it has been climbing again. So part of what you pay tracks a market that has done something dramatic, and part of it doesn’t. Only one of those is worth your attention.

Car insurance prices held near their 2015 level until 2022, then rose sharply to a peak of 203.3 in December 2023, roughly double the 2015 base. They have since fallen back to 188.3 in August 2026, though the past twelve months show prices rising again.

Cheapest doesn’t always mean best.

Three alternatives, set against what you would actually pay and what you would actually get. Ranking on price alone hides the parts that matter at the point you claim.

Built around transparency.

An explanation is only worth having if you can tell how much weight it carries. Every statement the platform makes is labelled with where it came from.
Confirmed information
Information you provide directly, or details verified through data we can actually see. Stated as fact, because it is one.
Market evidence
Broader insurance pricing and market information, kept separate from your own circumstances so you can tell the two apart.
Potential drivers
Factors that may be influencing your premium, based on the information available. Presented as reasoning, never as certainty.

Underwriting models are proprietary, and insurewhy does not claim to know how any individual insurer prices a policy. Where something is an inference drawn from available information, it is shown as one.
