Wannon Water outcomes reporting

This page summarises Wannon Water's performance against its outcomes, measures, and targets for the regulatory period 2023–28. This is the second year of reporting against its 2023 price review commitments.

More details are available on our outcomes reporting page, and on Wannon Water’s website.   

What are outcomes?

Water businesses are accountable to their customers for delivering the outcomes set out in their price submissions, under our PREMO water pricing framework. Each business is required to report at least annually to its customers on:

• its performance against the specified measures and targets for each outcome
• an overall assessment of whether it has delivered on expectations for each outcome, including the business’s explanation for any performance shortfalls and how it intends to address them.

We have requested businesses also provide us with a summary outcome report document using a standard template. The self-assessments use a simple “traffic light” rating: 

• green = achieved target
• amber = mostly achieved target
• red = failed to achieve target.

Our observations on its 2024-25 performance

Wannon Water only met 11 of its 23 targets in the second year of its regulatory period. Its self-assessment was reasonable and explained why it did not meet or did not quite meet over half of its targets. Its submission did not mention whether Wannon Water consulted with its customers to inform its self-assessment. It reported its outcomes performance prominently on its website homepage, demonstrating ownership of its performance.
