Six water firms in England ‘overcharged customers by up to £1.5bn’

Firms underreported true scale of sewage pollution for 10 years, which allowed them to set higher bills, tribunal told

Six water companies overcharged customers between 800m and 1.5bn by significantly or systematically" underreporting the true scale of their sewage pollution of rivers and waterways, a tribunal has heard.

In the first environmental competition class action against water companies in England, lawyers argued that the privatised firms had abused their monopoly position to mislead regulators over the amount of sewage they were discharging from their assets over the past 10 years.
