About APER

The AIRAH Professional Engineer Register (APER) is the professional accreditation designed for engineers operating in the HVAC&R building services industry.

Being on the APER demonstrates to the public that you are an engineer who is qualified, competent, and ethical.

The APER is open to both AIRAH members and non-members.

AIRAH members on the register may carry the post-nominal of AIRAH Registered Professional Engineer (ARPEng) – the practical mark of quality in engineering.

In Australia, states and territories are responsible for statutory registration of engineers. Statutory registration ensures engineers meet professional conduct, education, training, and competency standards. The registration requirements are different for each state and territory. Professional engineers must register in each jurisdiction where they plan to practise.

AIRAH via the APER is an accredited assessor for State and territory registration for the ACT, QLD, VIC and WA. During the process of gaining APER registration we will assess you for one chosen state and provide an endorsement letter you can provide during your state registration to confirm your qualifications, experience and competency. During our assessment you may need to provide additional information above the APER requirements to meet a specific states requirements. Please refer to the State information provided.

Once registered in one State or territory you may be able seek mutual recognition for other States or Territories registration or where not available seek further endorsement for additional States or Territories through additional APER assessment.

Currently NSW, NT, TAS and SA have independent or no State registration requirements and you should refer to their respective government sites for further information.

Engineering professionals in mechanical engineering – HVAC&R building services are those who plan, design, install, commission, operate, tune, and maintain mechanical machines and systems in the built environment. This includes air conditioning plants, ventilation systems, chillers, cooling towers, refrigeration systems for food production and preservation applications, transport cooling systems, fire and smoke systems, medical facilities, and control systems.

Mechanical engineer – HVAC&R building services disciplines

A discipline is a subgroup of the engineering profession with which practitioners align their skills and work activities. Formal and informal education and work experience will influence how an engineering practitioner identifies with a discipline.

AIRAH is focused on representing mechanical engineer – HVAC&R building services professionals. These are professional engineers whose work is associated with, but not restricted to, the heating, ventilation, air conditioning, and refrigeration (HVAC&R) and building services industry. Learn more about the industry here.

The APER accreditation is aligned with registration in state-legislated schemes as a professional engineer in the mechanical engineer discipline.

The mechanical engineer – HVAC&R building services discipline is rapidly changing and multi-faceted. The above description does not fully capture the scope and specialisations of activities, some of which can cross over with other disciplines. For example – sustainability, ESD, and resilience can be considered within environmental engineering, as well as other disciplines. Although not a mandatory requirement, when filling out the application we ask APER applicants to identify areas of specialisation related to their engineering activities.

Additional information on the mechanical engineer – HVAC&R building services discipline is available here.

Why should I apply to be listed on the APER?

Australia’s states are introducing professional registration schemes for engineers:

  • Queensland – The current Queensland Professional Engineers Act has been in operation since 2002.
  • Victoria – Has introduced the Professional Engineers Registration Act 2019, which commenced on July 1, 2021.
  • New South Wales – New South Wales has introduced the Design and Building Practitioners Act and Regulation, which commenced on July 1, 2021.
  • Australian Capital Territory – The ACT has introduced the Professional Engineers Act 2023 which commenced on March 6, 2024.
  • Western Australia - The Building services (Registration) Act 2011 was amended to include professional engineer registration commencing July 2024 and expands to include Mechanical Engineers from July 1, 2025

Please note: Currently registration in NSW is directly with the department of NSW Fair Trading. A pathway where registration may be achieved via a professional body of engineers approved by NSW Fair Trading  (such as AIRAH) is being developed. More information regarding registration of engineers in NSW may be found here.

As a result of these Acts, engineers will need to be registered if they provide “professional engineering services”.

The schemes have been founded on the principle that a minimum level of qualifications, experience, and continuing professional development are required to carry out professional engineering services. The AIRAH Professional Engineer Register accreditation scheme has been developed to meet these requirements.

A successful application to become listed on the APER will display to the industry – and to the public at large – your qualifications and commitment to the discipline. An APER listing confirms that your skills, professional development, and training are up-to-date, and that you are a qualified professional.

AIRAH members who have been granted APER accreditation will also be awarded the use of the AIRAH Registered Professional Engineer (ARPEng) post-nominal.

Where a successful applicant meets their nominated State or Territory Registration requirements they will also receive an endorsement letter confirming their qualifications, experience and competency for submission to their nominated State or Territory as part of their registration application.

How long does an APER accreditation last for?

Accreditation lasts for three years, contingent on ongoing continuing professional development activities (150 hours of CPD over a three-year period, with a minimum of 50 hours each year) and adherence to the APER Code of Ethics (available via the APER Resources page) related to the state/territory you are registered in.

You must apply to renew your APER accreditation each three years by completing the renewal application and providing your current CPD evidence for assessment.

A State or Territory Registration endorsement letter lasts for one year. If State or Territory Registration is not sought within this time an endorsement reassessment will be required before applying for State or Territory Registration.
