3. Guideline-making powers

These Guidelines are issued under section 103EC and 103ED of the Act.

Explanatory note

Under section 103BD of the Act, insurance guidelines may provide for the determination of insurance premiums.

Under section 103ED (4) of the Act, insurance guidelines may adopt the provisions of other publications, whether with or without modification or addition and whether in force at a particular time or from time to time.

Under section 103ED (7) of the Act, it is a condition of licence issued under Part 6C that licensed insurers comply with the relevant provisions of these Guidelines.

4. Scope of the Guidelines

4.1 The Guidelines apply to all insurers that are the holder of a licence that is in force under Part 6C of the Act and includes SICorp.

4.2 These Guidelines specify:

    4.2.1 the minimum requirements for contracts of insurance

    4.2.2 how insurers are to present premium filings to the Authority, and

    4.2.3 how the Authority will assess those filings.

Explanatory note

These Guidelines do not apply to alternative indemnity products (AIPs) under the Act. The determination of premiums or other charges for provision of cover by means of AIPs are governed by a separate AIP Guideline issued under section 104E of the Act.

5. Product categories

5.1 Licensed insurers may offer any one or more of the types of contracts of insurance provided for by the HBC legislation, being:

    5.1.1 construction period insurance contract

    5.1.2 warranty period insurance contract

    5.1.3 any other contract of insurance in relation to residential building work that is required by section 92 of the Act, or

    5.1.4 any other contract of insurance in relation to residential building work that is required by section 96 of the Act.

5.2 Licensed insurers may specialise and choose to offer a particular form(s) of contract of insurance.

5.3 Licensed insurers must price each contract of insurance according to the premium methodology approved by the Authority.

Additional products

5.4 Licensed insurers may offer additional products and/or product extensions that provide for matters beyond the minimum requirements set out in the HBC legislation. Additional products or product extensions may include, but are not limited to:

    5.4.1 top-up cover for additional risks. For example, first resort cover where a home owner may claim in situations where a contractor is solvent and trading, or

    5.4.2 additional warranty cover for extensions to the warranty period.

5.5 Additional products must be submitted to the Authority for approval in compliance with these Guidelines.

5.6 A licensed insurer’s premium filing must separately address:

    5.6.1 the minimum requirements set out in the Act and the Regulation, and

    5.6.2 the additional product/product extension.

6. Premium principles

6.1 Licensed insurer premium filings must demonstrate compliance with the following principles:

Principle 1: Premiums are fair and reflective of risk

6.2 Premiums should be fair and reflect each contractor’s level of risk.

6.3 In general, fairness can be assessed relative to similar cohorts of contractors. The intention is that contractors that engage in similar industries, business activities, and share similar risk metrics should have similar premium rates.

6.4 The licensed insurer must show that its proposed target average premium rate for a particular cohort fairly reflects the expected claims costs, expenses and suitable profit margin for that cohort.

Principle 2: Premiums should not be excessive or inadequate

6.5 The HBC scheme should be fair, affordable, and financially viable.

6.6 At a scheme level, premiums should not be excessive or inadequate. Affordability in this context relates to the premium burden and the subsequent impact on the NSW economy.

6.7 In accordance with section 103BG of the Act, the Authority may reject a licensed insurer’s premium filing if it is deemed to be excessive or inadequate, or does not conform to the relevant provisions of these Guidelines.

Principle 3: Premiums should not be unreasonably volatile

6.8 Premiums should not be unreasonably volatile year on year.

6.9 Licensed insurers must demonstrate that premium movements reflect changes in the actual or perceived level of industry and contractor risk.

6.10 Premiums should consider experience over the entire building cycle. In doing so, premiums should not vary according to the phase of the building cycle.

Principle 4: Premiums should provide incentives for risk management and good business practices

6.11 Premiums should provide incentives for contractors to improve business practices thereby reducing both the likelihood and severity of potential future claims.

6.12 Licensed insurers may offer contractors discounts or load premiums based on the licensed insurer’s risk management practices. Discounts and loadings must conform with principles one, two and three and should be designed, to the extent possible, to generate incentives to reduce the level of risk.

6.13 At the same time, perverse incentives or incentives that might compromise the scheme must be avoided.

Principle 5: Premiums to be consistent with licensed insurer’s capital requirements

6.14 Licensed insurers are required to have a capital management plan in place that recognises the financial and insurance risks inherent in HBC portfolios. A licensed insurer’s premium basis needs to be consistent with their approved capital management plan.

6.15 In setting premiums, SICorp must comply with NSW government competitive neutrality principles.

7. Premium requirements for licensed insurers

7.1 Licensed insurers must quote a premium for all contractors the licensed insurer has deemed eligible, in accordance with the HBC (Eligibility) Insurance Guidelines.

Factors to be used in pricing

7.2 Licensed insurers must submit pricing for each contract of insurance option to the Authority for assessment and approval before making the offering to the market.

7.3 Factors that a licensed insurer must consider in pricing are:

    7.3.1 contract value,

    7.3.2 construction type, and

    7.3.3 contractor risk factors.

7.4 Licensed insurers may also consider in pricing the factors of:

    7.4.1 location of premises, and

    7.4.2 developer risk ratings.

7.5 Licensed insurers may apply to the Authority for approval to use additional factors. If a licensed insurer would like to use additional factors in the licensed insurer’s determination of premiums, these must be submitted in writing to the Authority for for consideration by the Authority, along with clear reasons.

7.6 Licensed insurers must demonstrate that any proposed additional factors comply with the premium principles of these Guidelines.

7.7 The Authority can approve or reject these additional factors for use in premium pricing.

Contract value

7.8 Licensed insurers must price contracts of insurance in accordance with the contract price of the contract for the work to be insured (or, if there is no contract price, the reasonable market cost of the labour and materials involved), excluding the cost of the HBC insurance (being the premium and any applicable taxes and insurance intermediary fees).

Construction type

7.9 Licensed insurers must price contracts of insurance in accordance with the categories specified below. Any additional categories must be submitted to and approved by the Authority before being used to class premium pricing.

7.10 In the event that a project does not fall within any one of the defined construction type categories, the licensed insurer may assign the project to the category that the licensed insurer considers best aligns to the level of project risk.

7.11 References to a ‘Class 1a’, ‘Class 2’ or ‘Class 10’ or ‘mixed use’ building or structure in the below definitions of construction type categories have the same meanings as they do for the purposes of the National Construction Code published by or on behalf of the Australian Building Codes Board.

7.12 ‘Secondary dwelling’ has the same meaning as in the principal local environmental planning instrument prescribed by the Standard Instrument (Local Environmental Plans) Order 2006.

11. Dispute resolution process

11.1 Licensed insurers must have a process in place where a contractor may appeal aspects of their premium determination. The dispute process must include as a minimum:

Explanatory note

A contractor may request that the Authority undertake a regulator compliance review to investigate potential breaches of the Act, the Regulation or any of the insurance guidelines. A regulator compliance review is not a mechanism of appeal to review the merits of a particular premium, and does not overturn premium decisions.

The Authority may audit a licensed insurer to determine compliance with these Guidelines.
