An updated look at the professional indemnity insurance market for UK fire engineers. Have premiums stabilised, and are exclusions for certain building types still prevalent?. PII for Fire Engineers: A Mid 2026 Market Analysis The professional indemnity insurance (PII) market for UK fire engineers, once a tempestuous sea of soaring premiums and restrictive clauses, appears to have found a precarious equilibrium by mid 2026. While the existential threat of uninsurability has largely receded, the landscape remains significantly altered from the pre Grenfell era. Premiums, though stabilised, remain elevated, reflecting a recalibrated risk appetite among insurers. Crucially, exclusions for certain building types, particularly those involving high rise residential or complex facades, persist as a defining feature, underscoring the enduring impact of regulatory reforms and heightened scrutiny on fire safety design. This analysis delves into the current state of the PII market, examining the factors that have shaped its trajectory and what this means for fire engineering practitioners across the UK. Background The PII crisis that gripped the fire engineering profession in the wake of the Grenfell Tower tragedy was unprecedented in its severity. Insurers, reeling from the potential for colossal claims stemming from systemic failures in building safety, drastically reassessed their exposure. This led to a dramatic contraction of available cover, significant premium hikes – often by several hundred percent – and the widespread introduction of onerous exclusions. Many fire engineering firms, particularly smaller consultancies, found themselves in an untenable position, facing the prospect of operating without adequate PII, a prerequisite for most professional engagements. The core of the problem lay in the perceived and actual risks associated with fire safety design, particularly for residential buildings over 18 metres. The systemic issues exposed by the Grenfell Inquiry, coupled with the subsequent legislative response – notably the Building Safety Act 2022 (BSA 2022) – fundamentally altered the risk profile of fire engineering work. The BSA 2022, with its extended liability periods and focus on accountability for building safety risks, amplified insurers' concerns. The Fire Safety Order 2005 (RRO 2005) also saw renewed enforcement vigour, further highlighting the responsibilities of those involved in fire safety. The market response was a classic example of risk aversion. Insurers either withdrew from the sector entirely or imposed stringent conditions, including specific exclusions for cladding, external walls, and even entire building types. This created a significant bottleneck, impeding the progress of vital building safety remediation work and placing immense pressure on the fire engineering profession. Key Developments By mid 2026, several key developments have contributed to the current state of the PII market: Stabilisation of Premiums: While not returning to pre 2017 levels, premium increases have largely plateaued. Insurers have refined their risk models, incorporating the impact of the BSA 2022 and the evolving regulatory landscape. This has allowed for more predictable pricing, albeit at a higher baseline. The initial shock of exponential increases has subsided, replaced by a more considered approach to underwriting. Persistent Exclusions for High Risk Buildings: The most significant and enduring feature of the current PII market is the continued prevalence of exclusions for work on high rise residential buildings (HRRBs), particularly those with complex or combustible external wall systems. While some insurers offer limited cover for such projects, it often comes with substantial excesses and highly specific conditions. This reflects the ongoing uncertainty surrounding legacy issues, the potential for future claims under the BSA 2022, and the sheer complexity of remediating existing buildings. New build HRRBs may find slightly more favourable terms, but exclusions related to external walls often remain. Differentiated Underwriting: Insurers are increasingly differentiating between firms based on their specialisation, experience, and internal risk management processes. Firms demonstrating robust quality assurance, adherence to standards like BS 9991/9999, and a clear understanding of the BSA 2022 requirements are finding slightly better terms. Those actively engaging with PAS 9980 for external wall assessments and remediation are also viewed more favourably, provided their methodologies are rigorous and defensible. Emergence of Specialist Brokers and Insurers: The crisis spurred the growth of specialist PII brokers and, to a lesser extent, niche insurers dedicated to the fire safety sector. These entities possess a deeper understanding of the technical intricacies of fire engineering and the evolving regulatory environment, enabling them to better articulate risk to underwriters and secure more tailore
