Kelda Group is a British utility company.
It is based in Bradford, England.
It was formerly listed on the London Stock Exchange and a constituent of the FTSE 100 Index, but was taken private in a £3.04 billion deal in February 2008 by Saltaire Water, a consortium of investment companies including Citigroup and HSBC.
Kelda Group, originally known as Yorkshire Water plc, was one of the regional water companies privatised in 1989.
It changed to its current name in 1999.
In 2000 Kelda purchased the United States water supply business Aquarion and subsequently announced the conditional sale of this asset in February 2006.
