Industry Awards

Office buildings may have a simpler tenancy profile than retail or industrial strata, but they still benefit from access to multiple underwriting markets. Building age, lift systems, and HVAC complexity all affect underwriting.

Building Plant Complexity

Office buildings rely on complex building systems: lifts, HVAC, fire suppression, and backup power. Machinery breakdown cover is essential and often overlooked in standard strata policies.

Sum Insured Accuracy

Underinsurance is one of the biggest risks in office strata. We help ensure your building valuation reflects true replacement cost, not market value. This protects the owners corporation at claim time.

WHY TANK INSURANCE

How we help office building strata schemes

Office buildings have underwriting considerations around building systems, tenant obligations, and sum insured accuracy. We have access to multiple strata underwriting markets and place office strata cover across Australia.

Building Systems Considerations

Lift age, HVAC type, and electrical infrastructure all affect underwriting. We present these details clearly to underwriters to support competitive terms.

02

Competitive Re-Marketing

We re-market office strata policies annually across multiple underwriters. Office buildings are generally well-regarded by insurers so competitive pricing is achievable.

03

Valuation Guidance

We work with building valuers and can advise when a revaluation is needed to ensure the sum insured is accurate and the scheme isn't exposed to underinsurance.

04

Lease Compliance Support

We can provide certificates of currency and advise on insurance clauses in commercial leases to protect the owners corporation.

RISK ASSESSMENT

Key Risks for Office Building Strata

Office strata buildings face specific risks driven by building complexity and commercial occupancy.

Fire from electrical faults in aging switchboards and server rooms
Water damage from burst pipes, air conditioning condensation, and roof leaks
Lift and escalator breakdown affecting building accessibility and tenant operations
Public liability claims from visitors, delivery drivers, and contractors in common areas
HVAC system failures causing business disruption for tenants and common area discomfort
Building defects in newer office towers including cladding and waterproofing failures
Security breaches and malicious damage in car parks and after-hours access areas
Storm damage to roofing, glazing, and external facades on high-rise buildings

Even a 'straightforward' office building can present underwriting challenges if the building systems are dated or the claims history is poor. Access to the right underwriters makes a measurable difference.

QUESTIONS

Office Building Strata Insurance FAQs

Office building strata insurance covers the building structure, common property (lobbies, lifts, car parks, bathrooms), public liability in common areas, office bearers liability, and optionally machinery breakdown for lifts, HVAC, and other building plant.
Generally, yes. Office buildings typically have lower fire risk and less hazardous tenancies than retail or industrial strata. However, higher sums insured, older building systems, and claims history can still make placement challenging. We market across multiple underwriters to ensure competitive pricing.
Yes. The strata policy covers the building and common property, not individual tenant fitouts, equipment, or business interruption. Tenants should hold their own business insurance covering their contents, liability, and loss of revenue.
Office buildings with ground-floor retail, a gym, or a cafe become mixed-use buildings from an underwriting perspective. The non-office tenancies affect pricing and insurer appetite. We handle mixed-use placements regularly.
The sum insured should reflect the full replacement cost of the building, including demolition, removal of debris, professional fees, and council compliance costs. A qualified building valuer should assess this. Underinsurance is a common issue in office strata and can result in claims being reduced proportionally.
