Why do Builders Need Insurance?

Building is a complex industry with myriad risks. It involves handling costly equipment, working in varying environments, and coordinating diverse teams. Accidents happen, equipment breaks or gets stolen, and sometimes disputes with clients may arise.

As a builder, you need insurance to cover potential risks and unexpected incidents that could lead to financial loss. A robust insurance policy helps mitigate these risks and lets you operate your business with peace of mind.

Building Insurance Claims Examples

To illustrate the importance of comprehensive cover, here are five examples of incidents and the insurance that would cover them:

Door Left Unlocked

A worker accidentally leaves a client’s house unlocked, resulting in a burglary. Public liability insurance could cover the losses.

ClaimsExample 75

Painting Damaged

A painting is damaged when a worker brushes past it. Public liability insurance could cover the cost of the painting’s repair or replacement.

ClaimsExample 76

Van Break-In

Your van is broken into overnight and expensive equipment is stolen. Commercial vehicle insurance would cover the damage to the vehicle, while plant/tools insurance would cover the stolen equipment.

ClaimsExample 77

WorkSafe Investigation

After an incident on site, your business is under a WorkSafe investigation. Statutory liability insurance could cover the legal expenses.

ClaimsExample 78

Defective Work

ClaimsExample 79

What to Watch Out for with Builders Insurance

When selecting insurance, it’s essential to understand the terms and conditions and identify potential gaps in coverage. Here are some points to consider:

Property being worked on / defective workmanship cover

Ensure that your public liability policy covers property being worked on and defective workmanship. Without this, there’s no cover for anything you’re actively fixing or working on.

Public Liability Limit

Consider obtaining a high enough public liability limit. Recent claims in New Zealand suggest a limit of $2,000,000 or more, even for businesses solely in the residential space.

Keys & Locks Cover

Include keys and locks cover in your public liability policy. This covers the cost of replacing locks if you lose a key.

Theft Cover Exclusions

Check whether theft cover is included in your tool insurance. Policies vary; some cover open-air theft, while others are more restrictive.

Paying into a fraudulent bank account

Beware of scams. If you inadvertently transfer money to a fraudulent account, cyber insurance can cover the loss.

Rented/Hired Equipment

Check whether your policy covers hired equipment. If rented machinery is damaged or stolen, you could be liable for the costs.

Subcontractors Cover

Ensure that your insurance covers subcontractors. Subcontractors can often be a gray area in liability insurance, leaving you exposed to potential claims.

How Much Does Builders Insurance Cost?

The cost of builders insurance varies greatly, starting from as little as $300 a year for small businesses wanting public liability cover, up to thousands for large businesses with many vehicles and employees. Factors influencing the cost include:

Size and Turnover of the Business

Larger businesses with higher turnover typically pay more as they present a greater risk.


Rates may be higher in areas with a higher incidence of claims.

Who is Being Covered

The number and type of workers (employees, subcontractors) can affect the cost.

Claims History

Businesses with a history of many claims will typically pay more.

Level and Types of Cover Required

Comprehensive policies with high limits cost more.
