About Us

In the built environment you will find us at the intersection of risks to wellbeing, and global concerns for sustainability. In that place our people find meaningful work, leading to mutual relationships with our customers.

Our customers rely on us to manage risk by combining scientific knowledge with regulatory information, to develop solutions that are innovative, compliant and pragmatic. We inspire our customers to maximise the potential for wellbeing of their property occupants, with financial and environmental sustainability.

QED’s services include inspections, sampling and performance-rating of properties for office, retail, healthcare, education and industrial. Customers increasingly engage with us via our online services.

As a market leader in the assurance of built environment, QED holds multiple national certifications, including:

  • NATA Accreditations for Indoor Air Quality
  • NATA Accreditation for Hazardous Building Materials
  • NABERS Indoor Environment Assessors

QED is the first and only organisation in Australia to hold such accreditation for Indoor Air Quality inspections and NABERS Indoor Environment Base Building ratings.

To learn more about who we are and how we work we invite you to read our Policy Handbook

We also invite you to download our Reflect Reconciliation Action Plan: October 2020 - September 2021
