About the company

United Utilities Group PLC has a primary listing on the London Stock Exchange and owns, through two holding companies, United Utilities Water Limited, the licensed water and wastewater company for North West England. The company delivers drinking water to around 8 million people and businesses each day and runs a wastewater network of more than 79,000 kilometres of pipes.

The group board reviews performance on a single segment basis, so the report gives no regulated and non-regulated split of the kind other water groups publish. The water company's own report says its regulated activities are 98 percent of group assets, and that only a small amount of non-regulated activity sits outside it.

A water company two holding companies below the listing

The solid lines are ownership, as drawn in the group's own structure chart at 31 March 2026. United Utilities PLC and United Utilities North West Limited are intermediate holding companies, and neither is an operational entity. The water company also owns a financing company that raises debt for it and 74 percent of the estates company for the Lingley Mere business park.

The five boxes under the water company are its core activities as it lists them. Bioresources, the treatment of sewage sludge into energy, is part of the regulated business, not a side venture. The dotted line marks the 50 percent Water Plus joint venture with Severn Trent, which serves business customers and is held by United Utilities PLC.

How this structure supports the business

A list of group companies would hide that most of this group is one regulated company and that the listed parent sits two holding companies above it. The chart shows that the other entities have narrow roles: a financing vehicle, an estates company and a half-owned retailer. It also explains why the report needs only one financial segment.

Interesting facts

The water company's report says the regulated business's resources and interests are robustly ring-fenced from the group's non-regulated activities.
United Utilities PLC was the listed parent until July 2008 and has since been used to raise debt financing.
Water Plus is jointly controlled with Severn Trent, and United Utilities Water Limited is described as a key wholesaler supplying it.
