Scottish Water

Scottish Water is a public corporation established by the Water Industry (Scotland) Act 2002. It is accountable to the Scottish Government for the provision of all public water and sewerage services to more than 2.56 million households and around 153,000 businesses in Scotland. It is the fourth largest provider of water and sewerage services in the UK, with a workforce of more than 4000 and an annual turnover of roughly £1.4 billion. Its retail subsidiary Business Stream operates in the competitive retail market for non-household customers in Scotland and England.

The Water Industry Commission for Scotland, the independent economic regulator of Scottish Water, recently published its Final Determination for the next regulatory period 2021-27 setting the demanding financial limits within which Scottish Water must deliver the objectives set by Ministers. Those objectives include that it should make progress towards the achievement of net zero emissions by 2040. As part of its determination the Commission has also set out a radical new approach to regulation through ethical business practices which create new expectations for how Scottish Water works with its stakeholders and customers. The Commission will monitor and report on Scottish Water’s performance.
