Yorkshire Water is a water supply and treatment utility company servicing West Yorkshire, South Yorkshire, the East Riding of Yorkshire, part of North Lincolnshire, most of North Yorkshire and part of Derbyshire, in England. The company has its origins in the Yorkshire Water Authority, one of ten regional water authorities created by the Water Act 1973, and privatised under the terms of the Water Act 1989, when Yorkshire Water plc, the parent company of the Yorkshire Water business, was floated on the London Stock Exchange. The parent company was Kelda Group in 1999.[2] In February 2008, Kelda Group was bought by a consortium of infrastructure funds.

It is regulated under the Water Industry Act 1991.


The company's area includes West Yorkshire, South Yorkshire, the East Riding of Yorkshire, part of North Lincolnshire, most of North Yorkshire and part of Derbyshire. The area is adjoined on the north by that of Northumbrian Water, on the west by United Utilities, on the south west by Severn Trent Water and on the south by Anglian Water. It serves 2.3 million households and 130,000 business customers.

Environmental record

Yorkshire Water has received fines for breaches of environmental law. For example:


In June 1996, Yorkshire water was effectively fined £40 million by the regulator, Ofwat, by freezing their ability to raise bills for customers. This was a result of what Ofwat described as a "failure to deliver the standards required to consumers".[7] This fine was a result of being the most hated water company during the "year of the drought" (1995).[8] However, Yorkshire Water's performance had turned around so much so that the company was awarded the title by Utility Week magazine three years in succession while no other water company has won it more than once."[9]

1992 Sludge tip blocks River Colne Huddersfield

Landslip of sewage sludge engulfed a sewage works at Huddersfield in 1992. Almost 20,000 tonnes (20,000 long tons; 22,000 short tons) of sewage slipped from its Deighton waste tip on to the plant, and completely blocked 490 feet (150 m) of the River Colne. The disaster also forced the closure of a nearby ICI plant.[10]

1995 Year of Drought

For many months between September 1995 and January 1996 reservoirs in the west side of the region ran dry and water had to be taken by (up to) 700 tankers (delivering 70,000 litres (15,000 imp gal; 18,000 US gal) of water a day) from the east side of the region near Goole in a convoy of trucks with 3,500 daily deliveries along the M62 in a drastic emergency measure which cost £3 million a week. The trucks were famously shown on TV delivering water into Booth Wood Reservoir.[11][12][13] The company has now built a pipeline from the east to the west to allow balancing of water levels to take place should the need arise. Following the "year of drought" Yorkshire Water became known as "the most hated water company" during the many suspected Yorkshire Water would never be able to win back customers trust. However, though to a series of managerial changes and policy shifts, Yorkshire Water quickly turned things around, and won "Utility Company of the Year" from Utility Week Magazine for three years in a row, a record unmatched by any other water or energy company. The company have also either met or exceeded every leakage target set for the company by the Water Services Regulation Authority.

The company came under intense criticism when the Bransholme pumping station failed, worsening the flood damage of the city and flooding two thousand homes on the Kingswood and Bransholme estates. The pumping station was upgraded in 2015.

Customer service

Yorkshire Water ranked 11th of 21 water companies in Ofwat's 'Satisfaction by company' survey 2012/13.[14]

in January 2015 the UK Customer Service Index (UKCSI) announced that Yorkshire Water was the leader for service in the Utilities sector, they were also the second most improved organisation in the whole UKCSI, beating competitors such as Severn Trent, Anglian, Thames Water as well as United Utilities and EDF.

The UKCSI is the only external measure showing the state of customer satisfaction in the UK and allows individuals to benchmark across all sectors as well as utilities.

Not taking into account human composition: In the year ending 31 March 2013, 99.93% of Yorkshire Water's samples met the UK standards; in the previous year it was 99.95%.[15]

Carbon footprint

In 2012/13 the company's greenhouse gas emissions totalled 386 kilotonnes, compared to 394 kilotonnes the previous year.[15]
