About Consultation

This document consults on our proposals for how we will carry out the 2024 price review (PR24). The methodology will be used to set the revenues for water companies as well as the outcomes that they will need to deliver during the period from 2025 to 2030. We are seeking views from stakeholders on our expectations and requirements. This will help us finalise our methodology, which is a key milestone in our preparations for PR24.
