Join the water  overcharging claim

Has your water company broken the law and overcharged you?

If so, Join the Claim to get the justice and compensation you deserve.

Some UK water companies are accused of overcharging households. Legal experts say these companies underreported their sewage spills and discharges and have been allowed to raise their prices as a result.

Water companies can often set higher prices if they perform well and have limited pollution incidents. If these companies had reported truthfully, they would not have been allowed to increase prices, and customers might have had lower bills.

  • The six UK water companies accused of underreporting and overcharging are Anglian Water, Northumbrian Water, Severn Trent, Thames Water, United Utilities and Yorkshire Water.
  • Professor Carolyn Roberts, an environment and water specialist, has launched a legal case against these companies.
  • Professor Roberts is accusing the water companies of providing misleading information to The Water Services Regulation Authority (Ofwat).
