Water Company Performance Report 2022-23

Each year, Ofwat looks at the performance of the 17 largest water and wastewater companies in England and Wales across a set of key performance and expenditure metrics. The information in the report provides transparency for customers, and wider stakeholders, to see how water companies are performing on the issues that matter to them.

Information used in this report is taken from company’s annual performance reports. Alongside the report, we present the data in an interactive dashboard below, which allows users to select and view a specific company or year.

Headline findings

We set companies stretching performance commitments at the 2019 price review. Three years into the period, we see some areas where companies are responding to the challenge, but in many areas progress is not being made at the pace required to meet performance commitment levels.

  • Customer satisfaction continues to fall. Improving this should be a key priority for all companies.
  • Companies need to accelerate actions to reduce pollution incidents.
  • While many companies have made progress in reducing leakage, more improvement is needed.
  • Internal sewer flooding incidents have reduced, but the sector must continue to drive performance improvements.
  • More than half of companies have underspent their enhancement allowances in the period to date.
  • The sector has not delivered the anticipated improvements in water supply interruptions and must take action to address this. ​
  • We remain concerned about the progress from a number of companies in delivering their water resources management plans.
  • We are taking action ​to drive performance improvements, particularly for the poorest performing companies.

The dashboard below outlines companies’ progress in year three of the period and how performance in specific metrics is changing.
