Deregulation of the British Water Market

Our guide to deregulating the British water market and what this means for business.

Privatisation in England and Wales (1989)

In 1989, the English and Welsh water sectors were privatised, creating the world’s first fully privatised water system. Ten for-profit regional water authorities were created to supply households and businesses. These were:

Anglian Water
Dwr Cymru Water
North West Water
Northumbrian Water
Severn Trent Water
Southern Water
South West Water
Thames Water
Wessex Water
Yorkshire Water

Privatisation is thought to have achieved higher levels of investment in the industry, contributing to the high standards of water quality enjoyed by households and businesses.

Scottish water deregulation (2008)

Scotland was the first part of the UK to adopt the deregulated market for business customers. The change gave Scotland’s 130,000 businesses the right to switch business water supplier. Scottish Water customers were transferred to a newly created subsidiary, Business Stream. Upon deregulation, new water suppliers entered the market, giving the customers of Business Stream an alternative.

The new suppliers purchase water wholesale from Scottish Water and sell this to businesses along with additional services.

The introduction of competition into the market led to better service and lower business water rates.

Deregulation in England and Wales (2017)

In 2017 England and Wales followed Scotland’s lead and deregulated the supply of water to business customers. In response to the deregulation, the regional suppliers either created business retailing arms or they sold their business contracts to other licensed suppliers.

Businesses were informed of this default switch in their supply, but most have not taken any action to take advantage of this deregulation.

The current water market

Today all businesses in England and Scotland, and those of a certain size in Wales, can choose their business water supplier with a simple business water comparison.

There are currently 21 licensed suppliers of water in England, 20 in Scotland, and 13 in Wales. These suppliers offer competing levels of pricing and service.

What is the effect of deregulation on the British Water Market?

Deregulation has introduced competition into the market, with the suppliers now competing for customers. Suppliers are incentivised to provide better customer service at a more competitive price to benefit businesses.
