About the company

Severn Trent Plc is listed on the London Stock Exchange and is the parent of two regulated water and wastewater companies: Severn Trent Water in England and Hafren Dyfrdwy in Wales. Together they serve 4.7 million households and businesses across a region from the Bristol Channel to the Humber. Its annual report for the year to 31 March 2026 sets out the structure shown here.

The group reports two segments. Regulated Water and Wastewater covers the two licensed companies. Infrastructure Services, called Business Services until this year, covers Operating Services, Green Power, Property Development and the new Network Services business. Water Plus, the business water retailer, is a 50 percent joint venture reported outside both segments.

Two licensed companies and a renamed non-regulated segment

Solid lines follow the group's segmental note. Severn Trent Water and Hafren Dyfrdwy sit under Regulated Water and Wastewater, and the four named businesses sit under Infrastructure Services. The dotted line to Water Plus marks shared control: the group accounts for its half on an equity basis and its results are left out of the segment reports.

The segments do not match legal entities exactly. The regulated segment leaves out Severn Trent Water's affinity products, hydro-electric generation and property sales, which are reported in Infrastructure Services. Each regulated company also publishes its own annual report and an annual performance report for Ofwat. The Government's January 2026 White Paper confirmed plans to replace Ofwat, but legislation is still needed.

How this structure supports the business

A flat list of businesses would put Hafren Dyfrdwy, Green Power and Water Plus on the same level. The chart shows that two are separately licensed companies, four are non-regulated businesses sharing one segment, and one is a half-owned retailer outside both. It also shows where the 2025/26 relabeling happened.
