Nicola Shaw had been criticised over Yorkshire Water's pay and performance
Yorkshire Water's chief executive has announced she is to step down, just 24 hours after the company was given the lowest possible environmental rating by the Environment Agency
Nicola Shaw, who has led the firm since 2022, will leave the role on 1 January to be replaced by Nicola Medalova, a chartered environmental health officer who previously worked for the National Grid.
In a statement on Friday, Shaw said it had been a "privilege" to lead the company but that it was "the right time" to leave her post.
Shaw has faced criticism in recent years, including for taking £1.3m in undisclosed payments between 2023 and 2025, while the company has come under scrutiny for its performance.
