Why Are Warranty / Defects Liability Bonds Required?

Even well-managed construction projects can develop defects after completion. Common issues include:

  • Faulty installations
  • Structural movement
  • Water ingress
  • Mechanical or electrical failures
  • Material defects

If the contractor is unable or unwilling to fix these problems, the project owner may face significant repair costs.

Warranty / Defects Liability Bonds ensure that funds are available to correct these defects, protecting the owner from financial exposure.

They are often required at the end of the construction phase, as a replacement for retention, under large commercial or infrastructure contracts, or on public-sector projects.

How Does a Warranty / Defects Liability Bond Work?

A Warranty / Defects Liability Bond is usually issued at or near project completion. The typical process works as follows:

  1. The contractor completes the main construction works.
  2. A warranty or defects liability period begins, often lasting 12–24 months.
  3. The contractor provides a Warranty Bond in favour of the project owner.
  4. If defects arise, the contractor is required to return and rectify them.
  5. If the contractor fails to do so, the owner may claim under the bond.
  6. The bond provides financial protection throughout the warranty period.

When Are Warranty Bonds Commonly Used?

Warranty or Defects Liability Bonds are typically required in:

  • Commercial construction projects
  • Infrastructure and civil engineering works
  • Public-sector contracts
  • Mechanical and electrical installations
  • Design-and-build projects

They are often used where retention is being released early, or the employer wants additional financial security during the defects period.

How Much Does a Warranty / Defects Liability Bond Cost?

The cost of a Warranty Bond depends on several factors, including:

  • Financial strength of the contractor
  • Bond value
  • Duration of the warranty period
  • Project type and risk profile
  • Bond wording and contract requirements
  • Any additional security provided

Because these bonds cover post-completion risk, underwriting focuses heavily on the contractor’s financial stability and track record.

CG Bonds Surety works with an exclusive underwriting panel to secure competitive pricing, supported by our Best Price Guarantee.

Warranty Bond FAQs

How long does a Warranty / Defects Liability Bond last?

Most warranty periods last between 12 and 24 months, but this can vary depending on the contract.

Is a Warranty Bond the same as a Performance Bond?

No. A Performance Bond usually covers the construction phase, while a Warranty Bond covers the defects liability period after completion.

What value is a typical Warranty Bond?

Warranty Bonds are often issued for a percentage of the contract value, commonly replacing the retention amount.

Can a Warranty Bond replace retention?

Yes. Many contracts allow a Warranty Bond to be used instead of holding cash retention, improving the contractor’s cash flow.

What happens if the contractor becomes insolvent during the defects period?

If defects arise and the contractor cannot rectify them, the project owner can claim under the Bond to cover the cost of repairs.

How quickly can a Warranty Bond be arranged?

Timescales vary depending on the project and financial assessment, but CG Bonds Surety can often provide fast indicative pricing and efficient turnaround.

Do all projects require a Warranty Bond?

Not all projects require one, but they are common on larger commercial, infrastructure and public-sector contracts.
