Risk Exposure

Why M&E Contractors Need Professional Indemnity Insurance

Mechanical and electrical contractors routinely provide design services as part of their scope of work. Whether designing ductwork layouts, specifying electrical distribution systems, or coordinating fire safety installations, the professional exposure is substantial.

Building services failures can result in claims for system replacement, business interruption, consequential losses and — in the case of life safety systems — personal injury claims where the failure relates to professional negligence in design.

Standard contractors' insurance policies do not cover claims arising from negligent design or specification of building services systems.

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.

1

HVAC System Under-Design

An air conditioning system is designed with insufficient capacity for the building's actual heat loads. Complete system redesign and replacement is required, and a Professional Indemnity claim is made against the M&E contractor for the costs involved.

2

Fire Alarm Specification Error

A fire detection system is specified that does not meet the requirements of BS 5839. Retrospective upgrade of the entire system across a multi-storey building is required, resulting in a Professional Indemnity claim.

3

Electrical Distribution Failure

Incorrect specification of electrical switchgear results in repeated failures under load. The employer pursues a Professional Indemnity claim for replacement equipment costs and associated business interruption losses.
