Thames Water has been hit by a huge £122.7million fine for breaking rules on its wastewaster operations and dividend payments.

The fine, which is the largest Ofwat has ever issued, follows two 'big and complex' investigations by the regulator.

Ofwat said Thames Water would pay £104.5 million for the wastewater breaches and a further £18.2 million for breaking rules on dividend payments.

It said the fines would be paid 'by the company and its investors and not by customers'.

The regulator's probe into how the company was managing its treatment works and wider wastewater network uncovered a number of failings.
