Professional Indemnity Insurance for Engineers
Structural, civil, M&E and specialist engineers carry the core technical design responsibility on most construction projects. When engineering design fails, the consequences — structural collapse, system failure, remediation costs — are severe. Specialist Professional Indemnity Insurance is essential and frequently a contractual requirement.

Why Engineers Need Professional Indemnity Insurance
Engineers carry the technical design responsibility that underpins the safety, performance and durability of buildings and infrastructure. A single design error can lead to structural failure, building evacuation, or costly remediation — with claims frequently running into millions.
Professional liability for engineers extends across design calculations, specification, site supervision, certification, and coordination with other disciplines. The duty of care is owed not only to the commissioning client but, through collateral warranties, to funders, purchasers and tenants.
Most contracts and professional bodies — including ICE, IStructE and CIBSE — expect or require engineers to hold Professional Indemnity Insurance. The appropriate level of cover must reflect the scale and complexity of the work undertaken.

Illustrative Claims Scenarios
Typical Claims Scenarios
The following scenarios are illustrative examples only and are intended to demonstrate the types of claims Professional Indemnity Insurance is designed to respond to.
Structural Design Underestimation
A structural engineer underestimates loadings on a commercial floor slab. Subsequent deflection and cracking require structural strengthening and temporary support works, resulting in a Professional Indemnity claim.
Geotechnical Investigation Failure
Inadequate ground investigation fails to identify made ground and contaminated material. Foundation redesign and additional earthworks are required, and a Professional Indemnity claim is made including delay damages.
M&E Design Coordination Error
An M&E engineer's services design clashes with the structural frame due to inadequate coordination. Rerouting of services and associated finishes works is required, resulting in a Professional Indemnity claim.
