Consultation on proposed updates to Class A unit metering standards

Stage 1 consultation is complete. Thank you to everyone who contributed feedback.  

Our teams are reviewing feedback to determine where the proposed Standard and Standard Drawings may need refinement, where additional guidance may be useful, and where issues need to be considered through other processes.  

A further opportunity for Stage 1 contributors to review and validate the consultation report is expected late 2026, ahead of finalisation early 2027.  

What is changing and why?

ACT legislation requires individual water metering in new Class A and Class B units. This enables water consumption to be measured for individual units within developments, rather than relying solely on a shared meter for the building.  

We will be implementing these requirements through updates to our Standards, Standard Drawings and supporting processes.

What Stage 1 covered

Stage 1 ran from 23 July – 13 September 2026 and focused on the proposed technical requirements for Class A unit metering, including how meters are configured, installed and accessed within developments.  

We sought feedback on:

• Section 5 of the draft standard STD-SPE-M-006 Property Service Connections and Water Meters
• The three associated draft Class A Standard Drawings
• Whether the proposed requirements are practical, clear and fit for purpose.

The consultation did not seek feedback on:

• The ACT legislative requirements mandating individual unit metering for Class A and Class B developments
• Existing Class B requirements, which are already in effect
• Content with STD-SPE-M-006 outside section 5, and other Icon Water standards and Standard Drawings not included in the consultation package
• Billing systems and processes, other Icon Water systems and processes, or broader program delivery arrangements, except where explicitly addressed in Section 5. 

Stage 1 consultation activities  

Stage 1 consultation included two public webinars introducing the consultation documents, proposed updates and participation process; a series of technical workshops exploring the updates in more detail, written submissions and other engagement activities.

Stage 1 engaged developers, builders, designers, technical specialists, certifiers, strata managers, industry associations and government stakeholders.
