Our prices and price paths for a five year period commencing 1 July 2026 were reviewed through a public process across 2025 and 2026, where the Essential Services Commission:
- completed extensive analysis of our 2026 Price Submission, which set out the proposed revenue to meet the expected costs to deliver planned capital works programs and service standards for the forecast volumes for each prescribed service
- reviewed capital and operating expenditure for prudency and efficiency
- reviewed forecast demand and proposed tariff and charge structures
- consulted with stakeholders, including a review of submissions made by interested parties.
The Essential Services Commission determined our final prices and price paths in its Melbourne Water Price Determination that covers our five-year regulatory period from 1 July 2026 to 30 June 2031.
