UK motor insurance is having its quietest period in a decade. Prices are down, switching is at a historic low, and combined ratios are roughly back in balance.
It felt settled in late 2021 too. Then Russia invaded Ukraine.
Four eras define the modern market. The 2013-16 period was the LASPO reset, with referral fees banned, whiplash claims falling, and Insurance Premium Tax rising from 6% to 12%. Then came the 2017 Ogden shock: the discount rate was cut from 2.5% to -0.75%, PwC estimated it would add £50-£75 to the average policy and up to £1,000 for younger drivers, and our own data recorded competitive-end premiums inflating 16% between July 2016 and July 2017. That triggered roughly 500,000 additional switchers. Remember that number.

The Covid trough followed: traffic fell 21% in 2020, claims fell 19%, and young-driver premiums dropped hardest. Then the Ukraine surge. From late 2021 into late 2023, the market went through its sharpest rate cycle in modern history. The ABI's average premium peaked at £627 in Q4 2023, up 34% year on year. Supply chain disruption, soaring repair costs, and hardening reinsurance all fed through simultaneously.
Then the cycle turned. By end-2025 the ABI was reporting three consecutive quarters of falling premiums. The Confused.com/WTW index was down for the ninth consecutive quarter. Aviva completed its acquisition of Direct Line in July 2025. Market prices appeared to plateau around end-2025. And our switching data shows motor switching at around 35%, a record low.
Tensions between Israel and Iran escalated through 2024 and 2025. A twelve-day war in June 2025 ended in a ceasefire that broke down on 28 February 2026, when strikes against Iranian nuclear facilities triggered a wider response. The Strait of Hormuz, through which roughly 20% of global petroleum liquids transit, has been effectively closed to tanker traffic for much of the period since.
Three channels matter for insurance. Oil: Brent rose from around $61 at the start of 2026 to $118 by end of Q1, touching nearly $128 on 2 April. Shipping: war risk premiums for Hormuz transits rose from around 0.2% of hull value to between 1.5% and 3%, with tanker traffic reportedly falling more than 80%. Inflation: UK CPI was 3.0% in February 2026, with the Bank of England expecting a rise toward 3.5%, noticeable, but nothing like the 2021-22 trajectory.
The bull case: sustained oil above $100 feeds CPI, which feeds bodyshop labour rates. Parts distributors are already absorbing airfreight premiums. If the conflict extends into summer, the 1 July 2026 reinsurance renewal starts to reprice, and carriers begin nudging rates upward through Q4. EY's December 2025 outlook projected a 2026 combined ratio of 111% and a 3% rise in premiums, and that was before 28 February.
The bear case: this is not 2022. CPI is 3%, not 11%. Insurer capital is strong, with Aviva's Solvency II cover at 180% and Admiral's at 193%. The 1 January 2026 reinsurance renewal locked in favourable terms before the escalation. Supply chains have already been stress-tested through two years of Red Sea disruption, and UK motor premiums fell throughout. EV repair costs are falling as bodyshops gain experience.
On balance, the base case for 2026 is closer to the bear. A pause in softening, not a new cycle, unless three things arrive together: Brent sustained above $100 through Q4; a second shock disrupting Asian parts routing; and a material reset at the 1 January 2027 reinsurance renewal.
Brent's twelve-month moving average, not the daily spot. The Joint War Committee's listed areas. The ABI quarterly tracker, particularly the 50+ cohort where repair severity concentrates. The 1 July 2026 reinsurance renewal commentary. And above all, shopping and switching. In 2017, a rate shock delivered 500,000 additional switchers inside twelve months. If switching rebounds from the mid-30s to the high 40s through 2026, that will be the earliest signal the market has shifted from quiet to shocked, visible in our data before it shows in combined ratios, and well before it shows in annual results.
A quiet market is not the same as a resilient one.
