The company was founded in 1989 as South West Water plc at the time of the privatisation of the Water Industry in England.[3] In 1993 it acquired Haul Waste and in 1995 it bought Blue Circle Waste Management.[3] It changed its name to Pennon Group plc in 1998.[3] By 2016, the company employed approximately 4,500 people, and provided water and sewerage to 1.7 million customers in South West England.[4]

The company successfully saw off a takeover bid from Terra Firma in 2004.[5] It acquired Thames Waste Management in 2004,[6] Wyvern Waste in 2006,[7] Grosvenor Waste Management[8] and Skipaway Holdings in 2007[9] and Shore Recycling in 2008.[10] In 2016, the group acquired Bournemouth Water in a deal worth £100 million,[4] integrating the company with South West Water, but keeping the Bournemouth Water name.[11]

On 8 July 2020 global investment firm KKR completed its £4.2 billion acquisition of waste firm Viridor from Pennon Group.[12]


The company's main asset is South West Water, which supplies water and sewerage services in Devon, Cornwall, and parts of Dorset and Somerset.[13] South West Water covers 83% of the group's profits.[14]
