How Asbestos Affects Property Value, Insurance and Liability

Asbestos is often treated as a technical or compliance issue.

In practice, it is a financial and legal risk that directly affects how a property is valued, insured and managed.

For many property owners, the real impact of asbestos is not seen until:

• A sale is underway
• Insurance is reviewed
• Works are planned
• Or a problem is discovered mid-project

With tightening expectations around asbestos compliance and documentation, these impacts are becoming more visible — and more immediate.

The link between asbestos and property value

Asbestos does not automatically reduce the value of a property.

When value is impacted

Property value is typically affected when:

• The presence of asbestos is unknown or poorly documented
• The asbestos register is outdated or incomplete
• There is evidence of damaged or deteriorating materials
• Removal costs are likely but not quantified

Buyer and investor perspective

From a buyer's perspective:

• Unknown asbestos = unknown cost
• Unknown cost = risk discount

This often results in:

• Renegotiation of purchase price
• Delays in settlement
• Additional due diligence requirements

Practical reality

A well-documented property with a clear asbestos position is easier to transact than one with gaps, assumptions or outdated information.

Insurance implications

Insurance providers assess risk based on certainty, documentation and exposure. Asbestos directly influences all three.

Where issues arise

Insurance complications can occur when:

• Asbestos is present but not clearly documented
• Registers are outdated or not available when requested
• Previous works have not been properly recorded
• Exposure risk is not understood or quantified

Potential impacts

• Higher premiums
• Policy exclusions or conditions
• Additional reporting requirements
• Difficulty obtaining or renewing cover

Increasing scrutiny

As compliance expectations tighten, insurers are placing greater emphasis on:

• Current asbestos registers
• Evidence of review and active management
• Clear documentation of known risks and unknowns

Liability exposure

The most significant risk associated with asbestos is liability.

Duty of care

Property owners and managers have a duty to ensure that:

• Asbestos risks are identified
• Information is available to workers and contractors
• Appropriate controls are in place and followed

Where liability arises

Liability exposure increases when:

• Asbestos is disturbed during works
• Contractors are not informed of risks
• Registers are incomplete or inaccurate
• Known risks are not managed or monitored

Real-world trigger points

Liability issues commonly arise:

• During maintenance or minor works
• During demolition or refurbishment
• Following exposure incidents
• During regulatory investigation or claims processes

The cost of getting it wrong

When asbestos risk is not properly identified or managed, costs are rarely controlled.

Common cost impacts

• Work stoppages
• Emergency inspections and testing
• Unplanned removal works
• Project delays and contractor downtime

Secondary impacts

• Legal and compliance costs
• Insurance complications
• Reputational damage
• Increased scrutiny on future projects

Timing problem

These costs typically occur at the worst possible time — when work is already underway or a transaction is in progress.

The hidden cost: uncertainty

The most consistent issue across value, insurance and liability is uncertainty.

What creates uncertainty

• Outdated asbestos registers
• Non-intrusive inspections only
• Inaccessible areas not assessed
• Lack of documented review or intrusive follow-up

Why it matters

Uncertainty forces:

• Conservative decision-making
• Risk pricing by buyers and insurers
• Delays in approvals, settlement and works

How to protect your position

Managing asbestos effectively is not just about compliance — it's about protecting the value and usability of the asset.

1. Maintain a current asbestos register

• Ensure it reflects current site conditions
• Update following works, refurbishments or changes in use
• Address previous limitations and "no access" areas

2. Reduce unknowns

• Investigate previously inaccessible areas
• Use targeted intrusive inspections where required
• Confirm or eliminate suspected materials

3. Plan ahead for works

• Conduct pre-demolition or refurbishment surveys
• Identify risks before contractors are engaged
• Avoid reactive decision-making under time pressure

4. Ensure documentation is usable

• Make registers accessible and easy to brief from
• Ensure they can be relied on by contractors and project teams
• Keep records structured and up to date for future transactions and insurance reviews
