Economic Regulation of Water Services – Information Disclosure
On 11 September 2025 we published our draft decision package to introduce information disclosure requirements in the water sector. We are now seeking feedback from stakeholders. It’s your chance to have your say before we finalise our decisions. Submissions close 5pm on 20 October 2025.
Information Disclosure
One of the key tools we will use for economic regulation for the water sector is information disclosure (or ID) – a form of economic regulation that promotes transparency by requiring regulated suppliers to publicly disclose certain information about their performance.
We take that information, analyse it, and publish it in a manner that makes it easier to compare between regulated suppliers, and look at trends over time.
By shining a light on what’s going well and identifying and monitoring areas for improvement, we can encourage your local water service provider to improve efficiency and quality and incentivise it to innovate and invest for the long-term benefit of consumers.
Earlier in 2025, we published our Information Disclosure Discussion Paper as a first step in engaging with water sector stakeholders to understand their views on how we could develop a new performance reporting regime for water service providers. We published the responses we received and a paper that summaries the key themes and issues raised.
