The UK insurance market has entered a markedly soft phase, with conditions in the first quarter of 2025 becoming increasingly advantageous for buyers, according to new analysis published by Aon.
Rates fell by an average of 11 to 20 per cent across most classes of insurance, excluding motor cover, where premiums continue to edge upwards in response to inflationary pressures in vehicle repairs and supply chains. The consultancy noted that insurers were competing more aggressively on price and policy terms, aided by ample capacity and a general improvement in underwriting profitability.
“The market has ample capacity, greater underwriting flexibility, and broader coverage offerings,” said Josh Webb, head of London broking for Aon’s Commercial Risk division. “That puts buyers in a strong position to revisit their overall risk strategy.”
The construction market, particularly in traditional “four-walls” property risk, has seen premiums drop by as much as 20 per cent, supported by both established and new capacity. For complex engineering risks, however, pricing has remained flat, with underwriters demonstrating greater prudence.
Softening was also pronounced in professional indemnity (PI) and liability lines. PI rates fell by 5 to 15 per cent for large multinationals and up to 20 per cent for mid-sized firms, with coverage becoming notably broader. Meanwhile, liability insurance recorded rate reductions of up to 25 per cent for corporates.
“Insurers are aggressively chasing business,” said Mike Pearson, head of financial lines. “Terms are improving, exclusions are narrowing, and capacity is strong.”
Gabriel Field, head of casualty, noted that long-term agreements were being increasingly offered as insurers seek to retain clients and grow market share. “Soft market conditions continue at pace with no end in sight,” he said. “We are encouraging our clients to lock in where possible.”
Motor fleet insurance bucked the trend to a degree, with rates still rising — by 2.5 to 7.5 per cent — albeit at a slower pace. Claims inflation, driven by parts and labour costs, remains the chief concern. However, Aon indicated that well-managed fleets could achieve savings or renewal terms close to previous levels, as insurers expand appetite and face growing competitive pressure.
“Insurers are fighting harder to retain clients than they were a year ago,” said Adam Richardson, head of motor. “That’s translating into more favourable outcomes at renewal, particularly for those who haven’t been to market recently.”
Property insurance rates have also declined by 11 to 20 per cent, with cover widening and carriers offering flexible terms such as cancel-and-rewrite provisions. Helen Bailey, broking director, advised insureds to revisit policies cut during the hard market and to ensure values and risk data were up to date for renewals.
“If any of your covers were removed or reduced during the hard market, now is the time to request them back,” she said.
The recent shift is largely attributed to improved financial results among insurers. Many have reported underwriting profits, reversing a multi-year trend of adverse loss ratios driven by natural catastrophe events and Covid-era disruption. These healthier positions are fuelling growth plans and underwriting flexibility, Aon said.
“There are aggressive growth targets out there and arguably not enough business to meet them,” Bailey added. “That dynamic is unlikely to change in the short term.”
Despite the broadly favourable environment, Aon warned that macroeconomic and geopolitical volatility — including trade policy and global instability — could temper insurer optimism in the medium term.
Nevertheless, the firm expects current conditions to persist into the second half of the year and perhaps intensify further in the absence of major disruptive events.
Aon’s leaders emphasised that early renewal engagement and robust risk presentations remain critical to securing optimal outcomes. Beyond price, insureds were encouraged to focus on strategic alignment with insurers, sustainable cover, and long-term value.
“Chasing down the lowest price may not serve long-term objectives,” Webb concluded. “This is a moment to rethink the structure and breadth of your risk programme.”
