PROTECTING CONSTRUCTION SITES AGAINST THEFT, WEATHER DAMAGE & SITE LOSSES

Theft, vandalism and severe weather can derail your project overnight

Construction sites are exposed: open perimeters, high-value materials, plant and equipment left on site, and part-completed works that are vulnerable to storm and flood. Site-Based Risk Insurance is designed to protect against these events so one incident doesn’t wipe out your margin or put a project at risk.

What Site-Based Risk Insurance Can Cover

Protection for contract works, materials, plant and temporary structures against site-based perils.


  • Theft of materials, fixtures, fittings and equipment from site
  • Theft or attempted theft damage to site and property
  • Malicious damage and vandalism to works and site assets
  • Storm, flood and other weather-related damage (subject to terms)
  • Damage to temporary buildings, hoardings and scaffolding
  • Cover for site-based plant and machinery (own or hired-in, if selected)
  • Contract works cover for part-completed structures and re-building costs
  • Debris removal, professional fees and making-safe costs after an incident

FREQUENTLY ASKED QUESTIONS

+-

+ -

Does my Contractors’ All Risks policy already cover theft and weather damage?

Many Contractors’ All Risks policies include cover for theft and weather-related damage to contract works and materials, but the scope, conditions and security requirements vary. Site-based risk cover can help ensure these exposures are specifically addressed and limits are adequate.

+ -

Are there special security conditions for theft cover on construction sites?

Yes. Insurers often require minimum standards such as secure fencing, locked containers, immobilisation or tracking for plant, and removal of high-theft-attraction items where practical. We will highlight any warranties or conditions that must be met.

+ -

Is flood cover always included for construction sites?

Not always. In higher-risk flood areas, cover may be restricted, subject to higher excesses or specific conditions. Insure24 can help you understand any flood limitations and explore options to improve protection where possible.

+ -

Can tools, plant and hired-in equipment be covered under the same programme?

Yes. Site-based risk cover is often combined with sections for own plant, hired-in plant and tools, giving one programme to protect works, equipment and site assets, subject to appropriate limits and conditions.

+ -

What information is needed for a site-risk insurance quotation?

Insurers will usually need details of the project type and value, site location, duration, security arrangements, flood exposure, materials and plant values, and your claims history. Insure24 will guide you through the information required.
