HBCF premium guidelines

We use risk-based pricing, meaning builders will pay a premium based on their insurance risk profile.

hbcf insurance premiums for your project are calculated using:
  • the type of project
  • the total contract value for the project
  • your individual loading or discount rate
  • the location of the project.

Each builder is allocated an individual loading or discount to the base premium.

The loading, or discount, is based on your insurance risk profile as assessed using actuarial guidelines. It is not a reflection of the quality of your work as a building contractor.

There have been changes made to premium rates from 2017 onwards, and there will be additional changes later in October 2017 and 2018.

The premium calculator tool can assist you to identify the premium for your project.

Premium calculator

Minimum premiums

A minimum premium of $200 applies to all projects. 10% GST and a 9% stamp duty are applicable to hbcf premiums. Where the contract price for a residential construction project is not known, the reasonable market cost of the labour and materials involved in the project is used to calculate the applicable premium.

How risk-based pricing works

Based on hbcf insurance claims data, some characteristics have greater potential to increase the incidence of insolvency.

These characteristics are weighted for each builder to provide the premium loading or discount, which is then applied to the base premium for the type of work being undertaken.

For example, Incorporated entities (companies) have a significantly greater frequency of claims over sole traders and partnerships. This is reflected in the premium icare charges.

Other attributes taken into account as part of the risk-based approach include the period the entity has been licensed, retained (adjusted) net tangible assets and net profit.
