Ensuring quality in every rating
Accredited Home Energy Rating assessors provide trusted energy ratings that assess a home’s comfort and energy needs. They also offer tailored recommendations to help improve energy performance.
Two different accreditation streams
It is important to understand that there are two accreditation streams. Each stream has its own requirements and is managed by a different accreditation organisation or provider.
The first step to becoming accredited is to decide which accreditation you want to pursue – do you want to rate existing homes, new homes or both? You can become accredited to rate:
- Home Energy Ratings (NatHERS) for new homes and major renovations – ensuring home designs meet or beat National Construction Code (NCC) requirements before they are built, so they deliver long-term comfort and savings for households.
- Home Energy Ratings for existing homes – assessing existing, built homes to evaluate them as they stand – considering their age, design and current condition.
- You may be eligible for free or subsidised training or accreditation. Read the latest updates on training and accreditation subsidies in our News and Updates.

Training and getting accredited
Step 1: Complete the required training
Training providers:
All the required training to become a Home Energy Rating assessor for existing homes is currently being delivered by 2 Registered Training Organisations (RTOs):
- Northern Victoria Institute of TAFE (NVITAFE)
- Transformed
Start by completing 7 units of competency, drawn from the Certificate IV in Home Energy Efficiency and Sustainability (CPP41126), listed below:
- CPPCOM4001: Manage own work, professional development and ethical behaviour
- CPPHES4001: Research and assess impact of building elements on thermal performance of residential buildings
- CPPHES4002: Advise clients on thermal performance of residential buildings
- CPPHES4005: Assess household energy use and efficiency improvements
- CPPHES4007: Assess thermal performance of existing buildings
- CPPHES4009: Promote adoption of home sustainability practices
- CPPCOM4002: Implement safe work practices in the property industry (or equivalent as listed on training.gov.au)
- Recognition of Prior Learning may be available for these units.
You must also complete:
- the Home Energy Rating-specific training unit: Conduct Home Energy Rating assessments for existing homes, and
- training in any energy rating software tool that you intend to use, such as AccuRate Enterprise (existing homes mode), or an accredited third-party User Interface tool.
Streamlined training for current assessors
A streamlined training and accreditation pathway is available to assessors who are already undertaking home energy assessments, including:
- accredited Home Energy Rating (NatHERS) assessors for new homes
- licensed ACT Energy Efficiency Rating disclosure scheme assessors
- Residential Efficiency Scorecard assessors who were accredited when the program concluded on 23 June 2026.
Students eligible for the streamlined training are only required to successfully complete:
- the Home Energy Rating-specific training unit: Conduct Home Energy Rating assessments for existing homes
- training in any energy rating software tool that you intend to use, such as AccuRate Enterprise (existing homes mode), or an accredited third-party User Interface tool
- CPPCOM4002: Implement safe work practices in the property industry (or demonstrate prior completion).
The streamlined transition training pathway may be reviewed in the future.
Step 2: Prepare to apply
To help avoid disappointment, it’s important that you understand the eligibility criteria and the commitment required before investing time or money into the process.
Before applying, review the Code of Practice and key accreditation policies found in the assessor toolkit, including for character checks, conflicts of interest, performance management and continuing professional development (CPD).
Make sure you understand the responsibilities of being an accredited assessor before you start the application process. You or your employer must be willing to set appropriate privacy and work health and safety policies and obtain the required insurance coverage.
Insurance requirements include:
- professional indemnity insurance, with at least $2,000,000 in coverage
- public liability insurance, with at least $10,000,000 in coverage
You’ll also need to apply for a Nationally Coordinated Criminal History Check in line with the Character Check Policy.
Step 3: Submit an application to the AASP
Apply to the Assessor Accreditation Service Provider (AASP). This will require providing proof of identity, evidence of your completed training and a current criminal history check.
The AASP will assess your application for suitability and may also review your performance history from other accreditation schemes before making a decision. This review can include details of other energy rating schemes with which the applicant is or has been accredited, licenced, or certified within the past 10 years (see section 5.1 of the accreditation policy for further details).
The AASP may contact you during the assessment process to request additional information or clarification. Timeframes can vary depending on application volumes and whether further information is required.
Step 4: Pass the accreditation exam
If your application is accepted, the AASP will invite you to complete the assessor accreditation exam. The exam assesses your understanding of NatHERS policies, assessment processes and your professional responsibilities. You will receive further information about the exam at this time.
Step 5: Finalise your accreditation
If you successfully pass the exam, the AASP will contact you to finalise your accreditation. You’ll be asked to provide the following:
- evidence of professional indemnity and public liability insurance
- declaration of any conflicts of interest
- signed assessor agreement; and
- passport-style photograph for your accreditation card.
You may also need to pay any applicable accreditation fees. Your accreditation will be finalised once all required documentation has been received and approved.
Step 6: Receive your accreditation outcome
If your application is approved, you’ll receive an accreditation letter, accreditation number, an assessor card, supporting documentation, and access to the certificate portal.
If your application is not approved, you’ll be provided with the reasons for the decision and information about options at that stage.
Step 7: Maintain your accreditation
To remain accredited as a Home Energy Rating for existing homes assessor, you must meet all the requirements listed in the Code of Practice. This includes:
- complete at least 12 Continuing Professional Development (CPD) points, 6 of which must be technical points
- submit a minimum of 3 Home Energy Rating for existing homes assessments in at least one of the software tools you’re accredited to use
- maintain appropriate professional indemnity and public liability insurance
- comply with the Code of Practice and complete any required performance improvement actions.

Training and getting accredited
Step 1: Complete the required training
Start by completing the Certificate IV in Home Energy Efficiency and Sustainability (CPP41126). Only the awards offered under this qualification will qualify you to become accredited as a Home Energy Rating (NatHERS) for new homes assessor. Further details are available at training.gov.au
Please note CPP41126 supersedes but is equivalent to CPP41119 and CPP41212, and these are all suitable qualifications for accreditation.
As part of your training, you’ll gain experience in the NatHERS-accredited software tool you intend to use, such as BERS Pro, FirstRate5 or Hero. Check with your training provider to find out if they offer the software tool of your choice.
Step 2: Apply to an Assessor Accreditation Organisation
Once your training is complete, contact an Assessor Accreditation Organisation (AAO) to understand their specific accreditation requirements and application process. Each AAO manages assessor accreditation independently and may have additional training or assessment steps.
You can apply through one of the following organisations:
- Australian Building Sustainability Accreditation
- Design Matters National
- House Energy Raters Association
You may have additional requirements for your jurisdiction. Contact your local regulator to find out more:
Step 3: Maintain your accreditation
