Question to the Department for Environment, Food and Rural Affairs:

To ask His Majesty's Government which water companies have not been convicted of a criminal offence since privatisation.

Since the privatisation of water and sewerage companies in 1989, all ten Water and Sewerage companies which discharge into English waters have been convicted of criminal offences. In addition, since 1997, two water only companies, Bristol Water Plc and Portsmouth Water Limited have been convicted of criminal offences. Details of the enforcement action taken against water companies by regulators are available on the relevant regulator’s websites.

We will not let companies get away with illegal activity and where breaches are found, the regulators will not hesitate to hold companies to account. The Water (Special Measures) Act 2025 provides the most significant increase in enforcement powers to the regulators in a decade, giving them the teeth they need to take tougher action against water companies. In addition, water company bosses could now face up to two years imprisonment where investigations by the regulators are obstructed.
