Civil engineering insurance is complex – it is often the liability tail most businesses in the construction sector underestimate.
A design error may not surface for years. A drainage failure that causes flooding three years after handover. Ground settlement that emerges during a subsequent development. By the time the claim arrives, the site is closed and the team has moved on. Generic construction cover – designed for shorter-duration build risk – often isn’t built for this.
Professional indemnity: the cover that protects your expertise
PI insurance protects against claims arising from design errors, specification mistakes, miscalculations, and negligent project oversight. For civil engineers it’s the most critical cover – and the most commonly undervalued.
Policy limits typically range from £1 million to £10 million depending on contract values and tender requirements. Crucially, PI needs to be maintained for six to twelve years after project completion to cover the full window of liability exposure. Carrying insufficient limits can also disqualify you from tendering on major infrastructure contracts.
Contractors’ all risks and plant cover
Contract works insurance protects work in progress against fire, flood, theft, and accidental damage. The sum insured must reflect the full replacement value of works and materials at any point during the programme – not a figure set at the start and never revisited.
Hired-in plant deserves specific attention. If equipment you’ve hired is damaged or stolen, you’re typically liable for the cost regardless of fault. With plant and machinery theft estimated to cost the construction sector £70 million annually, this isn’t a peripheral risk.
Environmental liability
Earthworks and excavation near watercourses, brownfield sites, or sensitive land create real environmental exposure. A fuel spill during construction can require costly remediation and trigger significant regulatory fines. Environmental liability insurance is increasingly considered standard for civil engineering operations – not an optional add-on.
London market access for complex risks
Some civil engineering risks can’t be placed adequately in the standard market. Readhunt has direct Lloyd’s broker registration, giving us access to specialist syndicates with the appetite and expertise to properly underwrite complex or high-value civil engineering risks. For firms working on major infrastructure programmes, that access makes a genuine difference.
