Australia’s residential energy efficiency sector is entering an exciting new phase, creating new career opportunities for sustainability professionals, assessors, building consultants, and those looking to enter the growing home energy rating industry.
In a significant announcement published in the NatHERS News – May Edition, Transformed has been appointed as one of only two Registered Training Organisations (RTOs) selected to deliver NatHERS for Existing Homes Assessor training from the Stage 2 release in mid-2026. This appointment represents an important milestone in the expansion of the Nationwide House Energy Rating Scheme (NatHERS) and the future of home energy ratings across Australia.
For aspiring assessors and industry professionals, this development creates a clear pathway into a profession expected to play an increasingly important role in Australia’s transition to more energy-efficient housing.
A Major Milestone for the NatHERS Expansion
The NatHERS Administrator recently announced that two organisations have been appointed to deliver training for future existing homes assessors:
- Transformed
- Northern Victoria Institute of TAFE (NVITAFE)
The selected training providers will begin accepting enrolments from individuals across Australia interested in becoming NatHERS Existing Homes Assessors. The initiative supports the expansion of the assessor workforce needed to meet growing demand for home energy ratings and future energy disclosure programs.
This announcement forms part of the broader rollout of NatHERS for Existing Homes, which is designed to provide homeowners, buyers, renters, lenders, and government programs with reliable information about the energy performance of existing residential properties.
Why Existing Home Energy Ratings Matter
For many years, NatHERS ratings have been used to assess the energy performance of new homes and major renovations. However, the majority of Australian homes already exist, creating a significant opportunity to improve energy efficiency across the housing stock.
The expansion of NatHERS into existing homes is designed to help:
- Homeowners understand the energy performance of their property
- Identify cost-effective upgrade opportunities
- Support energy efficiency improvements
- Improve home comfort and thermal performance
- Reduce household energy costs
- Enable future home energy disclosure initiatives
The growing focus on residential energy efficiency is expected to increase demand for qualified assessors capable of conducting professional home energy assessments and providing evidence-based recommendations.
What Does a NatHERS Existing Homes Assessor Do?
A NatHERS Existing Homes Assessor evaluates the thermal performance and energy efficiency of an existing residential property using approved assessment methodologies and software tools.
Their work typically involves:
- Conducting on-site inspections
- Collecting building data
- Assessing thermal performance
- Modelling energy efficiency outcomes
- Producing home energy rating reports
- Identifying upgrade opportunities
- Supporting homeowners in improving energy performance
As Australia continues to prioritise energy-efficient housing and sustainability outcomes, qualified assessors are expected to become increasingly valuable across residential construction, retrofitting, property, sustainability, and consulting sectors.
Increased Support for New Assessors
One of the most encouraging updates announced in the NatHERS News – May Edition is the extension of financial support for future assessors.
From the Stage 2 release in mid-2026, new trainees seeking accreditation as Existing Homes Assessors will be eligible for a share of 150 accreditation and membership subsidies. The initiative is designed to reduce upfront costs for those entering the profession while supporting industry growth.
The subsidy program aims to:
- Encourage new entrants into the industry
- Expand the national assessor workforce
- Improve accessibility to accreditation
- Support the long-term success of the NatHERS Existing Homes program
This could significantly reduce the cost of becoming accredited once training is completed for prospective students.
Conditions apply, and eligibility requirements determined by NatHERS and accreditation providers may apply. Contact us to learn more at [email protected].
