AM Best has maintained its stable outlook on the UK non-life insurance segment, noting that headwinds and tailwinds affecting the segment’s operating environment remain broadly balanced despite elevated geopolitical risks.
The ratings agency said that continued minimal economic growth and rising unemployment into 2026 mean insurers are likely to face a declining demand for discretionary insurance products and increased price sensitivity, placing pressure on profit margins.
More positively, inflation continues to converge toward the Bank of England’s target rate of 2%. AM Best believes this could benefit the UK non-life insurance sector if accompanied by a corresponding decline in claims inflation.
However, ongoing geopolitical tensions, particularly in the Middle East, are fuelling uncertainty across global markets, which could lead to economic disruption.
Personal lines—mainly home and motor—remain among the most competitive segments in the UK, with demand highly price-driven. Even in strong underwriting years, many participants generate near-breakeven underwriting results, with overall profitability generally reliant on investment income and ancillary services.
Although motor pricing improved in 2024, rate decreases throughout 2025 amid competitive pressures have largely eroded these gains. According to the Association of British Insurers (ABI), motor insurance premiums fell for three consecutive quarters, albeit at a slower pace toward year-end.
At the same time, claims inflation persists, driven by expensive technologies in newer vehicles and the rising uptake of electric vehicles. As a result, AM Best expects margins to tighten further in 2026. While insurers may seek to maintain pricing discipline, any positive pricing momentum is likely to be transient in such a competitive and price-driven market.
Home insurance is the second-largest non-life class in the UK retail segment, accounting for around a quarter of business written.
Market conditions softened in 2025, with the ABI reporting a 4% year-on-year decline in average home insurance premiums in Q4, further reducing inflation-adjusted rates. At the same time, average claim costs rose 15% from 2024, marking another record year.
Despite easing general inflation, high material costs and labour shortages continue to drive up repair costs, while increasing weather-related losses are pushing up average claim costs.
With claims costs appearing structurally higher, continued premium reductions in 2026 could threaten margins, pointing to a challenging outlook for home insurers. AM Best expects disciplined underwriting and careful catastrophe exposure management to play a key role in achieving and sustaining profitability.
AM Best highlighted that UK commercial insurance margins declined in Q4’25, marking eight consecutive quarters of reductions. Casualty remained broadly stable, while property, cyber and financial lines were among the softest, impacted by competitive insurance capacity and improving reinsurance conditions.
The ratings agency also observed margin pressure from brokers seeking higher commissions, or by promoting placements via broker facilities, which can inflate acquisition costs.
As pricing pressures persist into 2026, AM Best expects underwriting margins to compress, which may prompt insurers to pursue more strategic responses. These could include portfolio optimisation and enhanced risk assessment insights to maintain underwriting discipline, but might also extend to other areas such as improving operational efficiency, likely through automation, or even mergers and acquisitions.
Dale Kirby, senior financial analyst at AM Best, said, “The overall profitability of U.K. insurers has benefited considerably from the elevated interest rate environment witnessed since 2022, as low duration fixed-income portfolios rolled over into higher reinvestment yields. AM Best expects investment income from these portfolios, which dominate the investment portfolios of the market, to remain robust through 2026, moderating the impact of softening rate conditions on the underwriting side and providing a steady stream of earnings.”
