Dee Valley Group plc was established in 1994 as the holding company for Wrexham Water plc (formerly Wrexham and East Denbighshire Water Company), the water supplier for Wrexham and the surrounding area.
In 1997, Dee Valley Group acquired Chester Waterworks, a neighbouring water company primarily supplying the city of Chester. Over the following year, the two water companies were combined to form Dee Valley Water plc, the head office being established at Wrexham.
Following disposal of non-water operations in 2002, the Group now comprises Dee Valley Group plc and its wholly-owned subsidiary, Dee Valley Water plc.
Dee Valley Group is an independent public company and is fully listed on the London Stock Exchange.
The main holder of the ordinary shares is Axa S.A. (35%) and there are around 1,200 corporate and individual shareholders.
