Moody's Ratings has kept a stable outlook on the UK insurance sector, but warned that falling prices will start to eat into property and casualty (P&C) margins next year, once the benign conditions supporting 2026 earnings fade.
The rating agency said P&C earnings had remained healthy this year, helped by reserve releases, benign weather and cheaper reinsurance. But it expects recent price declines to keep compressing margins through 2027, with the erosion becoming more significant from next year.
The picture varies sharply by line. Moody's said pressure on motor prices has eased as some insurers have exited or consolidated, while motor claims inflation has fallen from its post-pandemic peak to mid single digits. Those trends should support healthy motor underwriting, it said, provided pricing stays firm.
Home insurance prices are still softening, and commercial P&C prices are falling rapidly as capacity remains abundant. That matches what brokers are seeing at renewal. Marsh recorded UK commercial rates down 8% in the second quarter, with property down 11%. Other forecasts point the same way, with the market's combined ratio projected to rise from 89% last year to 95% in 2026 and 96% in 2027, as Insurance Business reported last month in its look at rates falling faster than claims.
Moody's also noted that the Prudential Regulatory Authority (PRA) is emphasising reserving discipline as prices soften. That is a signal that the reserve releases flattering this year's results may not be repeatable indefinitely.
Behind the softer pricing, the cost drivers remain. Moody's warned that more frequent severe weather could materially increase earnings volatility, even with cheaper reinsurance providing some offset. While 2026 has been benign, insurers paid a record £6.1 billion in property claims in 2025, including £1.2 billion of weather-related losses, according to the Association of British Insurers (ABI).
Vehicle technology is the other pressure point. Moody's said electric vehicles are generally more expensive to repair than petrol and diesel cars, and are more likely to be written off if their batteries are damaged.
The agency also flagged regulatory risk. Insurers face scrutiny over customer outcomes, claims handling and pricing practices, and it warned that any limits on risk segmentation or pricing flexibility could stop insurers repricing in line with rising claims.
On the positive side, Moody's said higher bond yields were helping insurers. The Middle East conflict has pushed UK government bond yields to levels not seen since 1998, and as legacy bonds mature, insurers can reinvest in higher-yielding assets. P&C insurers will see that uplift soonest, because they hold shorter-dated assets.
Capital also remains strong across the sector. Solvency ratios have eased from recent highs but remain robust, Moody's said, with insurers choosing to reinvest or return surplus capital rather than build it further.
For life insurers, the agency expects continued strong demand for bulk purchase annuities (BPAs), as pension schemes look to offload defined benefit liabilities, but said margins are narrowing as new providers enter and competition for long-dated assets intensifies. Growth in workplace defined contribution pensions should boost fee income. The agency also flagged rising liquidity risk where insurers use derivatives and repurchase agreements in their gilt strategies.
For commercial brokers, the Moody's view adds weight to a growing consensus that 2026 is close to the low point for pricing. If margins come under real pressure from 2027, insurers are likely to start holding rate on weaker risks and tightening terms before headline prices turn.
That makes the coming renewal season a good moment to lock in coverage, not just price. As Insurance Business has reported, the soft market has already raised concerns about underinsurance and coverage adequacy. Clients who have enjoyed several years of reductions may face a sharper adjustment if their sums insured and terms haven't kept pace.
