Comparing Latent Defects Insurance and Structural Warranties

Comparing Latent Defects Insurance and Structural Warranties

When navigating the realm of property insurance, you’ve likely encountered a diverse array of terms that may appear interchangeable. While some insurance policies may overlap in coverage areas, others serve to protect entirely distinct aspects.


You may be familiar with terms like ‘Latent Defects Insurance,‘ ‘Structural Defects Warranty’, ‘Building Warranty,’ and ‘Structural Warranty.’ But do they represent distinct policies, or are they simply different monikers for the same concept?

Distinguishing Latent Defects Insurance from a Structural Warranty

Fundamentally, latent defects insurance and structural warranties fall under the same category of policies. This insurance is designed to protect against defects in newly built, refurbished or converted residential developments.

There are different types of Structural Warranties including:

The standard term for a Latent Defects Insurance policy spans 10 years, though it can be extended to 12 years in certain cases. Moreover, supplementary coverage options encompass loss of rent, expenses for alternative accommodation, as well as coverage for mechanical and electrical damages.

The developer or contractor typically arranges the coverage, which will then be transferred to any subsequent beneficiaries following the sale.

Benefits of Latent Defects Insurance:

  • The policy offers first-party insurance, ensuring the policyholder does not need to establish fault, negligence, or liability of the involved parties.
  • Time-consuming & expensive litigation costs can be avoided as there is no need to prove negligence.
  • Offers an added layer of protection for your balance sheet
  • The insurance can be called upon quickly if the insured property experiences physical loss damage or is under imminent threat due to a latent defect, all within the terms and limits of coverage.
  • This policy is transferable to future owners and/or tenants of the building.
  • The technical audit process can identify defects before practical completion, enabling their rectification prior to the owner/developer assuming responsibility from the contractor. This independent audit during construction ensures not only quality but also compliance with plans and specifications, as well as the availability of insurance cover when needed.
  • In the event of contractor insolvency, this policy offers insurance protection for repairing or replacing damaged property, even if contractors and/or the professional team are no longer in operation.

Coverage of Latent Structural Defects Warranty

Latent structural defects are hidden flaws within the building’s structural components, such as its foundations and load-bearing walls, which may elude detection during initial inspections.

Structural issues may gradually manifest due to faulty design, materials, or construction work. Identifying such defects can span months or even years, underscoring why latent defects insurance policies generally span 10-15 years from the building’s completion. Broadly structural defects warranty covers:

  • The policy offers “full value” reinstatement coverage, complete with a built-in 5% per annum indexation to counteract inflation over the policy term.
  • Typically, policy periods span 10 to 12 years from the date of practical completion, aligning with the relevant statute of limitations.
  • The coverage extends to defects in design, workmanship, or materials. Additionally, policies can be extended to encompass mechanical and electrical defects, business interruption, and, if needed, new home warranties for residential owners.
  • This comprehensive coverage is accessible for a wide range of developments, including commercial, residential, and mixed-use projects.

Latent Defects Insurance vs. Building Insurance

It’s important to note that latent defects insurance differs significantly from building insurance, just as a building warranty distinguishes itself from building insurance. Building insurance is part of the broader spectrum of home insurance, primarily concerned with safeguarding against accidental damage, vandalism, or theft.

Latent defects insurance or structural warranties exclusively addresses the building’s structural integrity in the event of substandard construction. In contrast, building insurance typically encompasses a broader array of elements within the building, including fixtures and fittings, safeguarding them against events like break-ins, fires, or weather-related damages.

While both policies safeguard the policyholder against financial losses stemming from building damage, they do so in different capacities against distinct causes. Neither policy extends protection to the possessions within the building, a domain covered by contents insurance, another facet of home insurance.

Who Requires Latent Defects Insurance?

While not legally mandated for many property types, latent defects insurance proves indispensable for new builds or conversions, offering crucial protection against the potentially substantial costs of rectifying defective craftsmanship.

Developers and builders will find this instrumental in securing funding, irrespective of whether the property is residential, commercial, or a mixed-use space. Buyers or self-builders will also find it smoother to secure a mortgage loan with this coverage, assuring the bank of the security of their investment.

Hence, if you’re a developer, builder, or an individual embarking on a self-build project, it’s highly advisable to explore acquiring a latent defects insurance or structural defects warranty policy.
