In 2022 we called on water companies to trial new approaches to charging structures for household customers that could help support affordability, as well as potentially contribute to other goals such as greater water efficiency. In this document we summarise companies' proposals for household charging trials as set out in their 2024 price review (PR24) business plans. This allows customers, companies and other stakeholders to review and compare companies' plans to use charging trials to support households, in terms of both affordability and sustainability. This document is for information only. We do not offer observations or critiques of any company's plans because we are assessing plans separately as part of PR24 – our quality and ambition assessments (QAA): we will publish the results of the QAA as part of our draft determinations in May / June 2024.
