- 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 each builder's insurance risk profile as assessed using actuarial guidelines. It is not a reflection of the quality of the work of the building contractor.
As announced during 2017, reforms to the Home Building Compensation insurance scheme have been implemented to ensure that it regains financial stability so it can continue to protect NSW homeowners now and into the future.
Premium rate changes occurred in April and October 2017 and October 2018. As foreshadowed, following a premium filing submission to the State Insurance Regulatory Authority (SIRA), a further premium rate change will come into effect on 1 August 2019.
Premium rates have been adjusted to reflect the latest assessment of break-even premium rates for all construction types.
Multi-dwelling construction types will move to break-even premium rates through four rate increases across Financial Year 2019-2020 and Financial Year 2020 -2021 to alleviate the impact to building activities.
Premiums for New Duplex/Triplex construction type will be aligned with the New Single Dwelling premium rate.
The risk-based rating structure used to determine builder risk factors is unchanged.
A minimum premium of $200 applies to all projects. 10 per cent GST and a 9 per cent 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.
