Why Construction Businesses Need ISR Insurance

Construction companies invest heavily in plant, equipment, vehicles and materials - assets that are often stored at depots, workshops and temporary site compounds. These assets are exposed to theft, fire, storm damage and accidental destruction on a daily basis. Industrial Special Risks insurance provides the broad, all-risks cover that construction businesses need to protect their permanent premises, owned equipment and revenue.

ISR is distinct from contract works or construction all risks insurance, which covers individual projects. Instead, ISR protects your business infrastructure - the depot, office, workshop, stored materials and the revenue you earn. Together with project-specific cover, ISR forms the backbone of a comprehensive construction insurance programme.

Common Risks Facing Construction Businesses

Theft of Tools & Plant

Construction sites and depots are frequent targets for theft. Power tools, generators, excavators and other plant can be worth hundreds of thousands of dollars and are difficult to recover once stolen.

Fire at Depot or Workshop

Storage of fuels, solvents, timber and other combustible materials at depots and workshops creates significant fire risk. A fire can destroy equipment, vehicles and building materials simultaneously.

Storm & Weather Damage

Severe weather can damage site offices, temporary structures, stored materials and plant - particularly in exposed or coastal locations where construction activity is common.

Accidental Damage

The physical nature of construction work means accidental damage to owned property - from crane strikes to vehicle collisions at the depot - is an everyday reality.

Business Interruption

Damage to your head office, depot or key equipment can delay project starts, disrupt project management and result in lost contract revenue for extended periods.

Vandalism

Unoccupied site offices and compounds are vulnerable to vandalism, graffiti and malicious damage, particularly on projects in urban or publicly accessible areas.

Construction ISR FAQs

Contract works insurance (also known as construction all risks) is project-specific and covers the works being constructed, including materials and labour, for the duration of a single project. ISR insurance, by contrast, is an ongoing annual policy that covers your permanent premises, equipment, stock and business interruption. Many construction businesses carry both - ISR for their depot, offices and owned plant, and contract works insurance for each active project.
ISR can cover tools, plant and equipment at your permanent premises and, with appropriate extensions, at temporary project sites. However, cover for tools at unfenced or unsecured sites may be subject to specific security requirements and sub-limits. High-value mobile plant may need to be individually specified on the policy.
Absolutely. If your main depot, workshop or office is damaged by an insured event, business interruption cover responds to lost revenue and ongoing fixed costs while you are unable to operate. For construction businesses, this can include the cost of hiring temporary premises, re-establishing project management systems and the revenue lost from delayed contract starts.
Generally, no. ISR covers property you own or are legally responsible for. Subcontractors are typically responsible for insuring their own tools and equipment. However, if you have a contractual obligation to insure subcontractors' property, this can be arranged as an extension. It is important to check contract terms and ensure there are no coverage gaps.
