Ofwat

The Water Services Regulation Authority, or Ofwat, is the body responsible for economic regulation of the privatised water and sewerage industry in England and Wales.

Ofwat is primarily responsible for setting limits on the prices charged for water and sewerage services, taking into account proposed capital investment schemes (such as building new wastewater treatment works) and expected operational efficiency gains. The most recent review was carried out in 2014; reviews are carried out every five years, and thus the next will take place in 2019.

Ofwat consists of a board, plus an office of staff which carries out work delegated to them by the board.

The Environment Agency is responsible for environmental regulation, and the Drinking Water Inspectorate for regulating drinking water quality.

The water industry regulator in Scotland is the Water Industry Commission for Scotland.

History

Ofwat was set up in 1989 at the time when the 10 Water Authorities in England and Wales were privatised by flotation on the stock market. The resulting companies are known as "the water and sewerage companies"; this distinguishes them from around a dozen smaller companies which only provide water services, which were already in private hands in 1989 (having remained in private ownership since their creation in the nineteenth century). The water only companies provide water to around 25% of the population in England and Wales.
