- Business Services
- Corporate and other
Changes to our structure
In 2020, we made some presentational changes to our segmental structure, moving some activities from our Business Services segment to Regulated Water and Waste Water.
In 2019, the Bioresources and Developer Services businesses were managed by, and included in, Business Services. Both businesses now form part of the appointed businesses of Severn Trent Water and Hafren Dyfrdwy, and are included in the regulatory settlement determined by Ofwat and managed by our Regulated Water and Waste Water team. We have therefore amended our segmental presentation to include Bioresources and Developer Services as part of our Regulated Water and Waste Water business.
This chart sets out the ownership structure within the Severn Trent Group, showing those companies that connect our regulated and operating companies to Severn Trent Plc.
