Yorkshire Water chief Nicola Shaw quits a day after lowest environmental rating

Yorkshire Water chief executive Nicola Shaw will step down on January 1, a day after the Environment Agency gave the company one star out of four, classing it as poorly performing. The regulator said the firm caused 260 pollution incidents in 2025, its highest since 2011. Shaw, in charge since 2022, faced criticism over £1.3m in undisclosed payments. Nicola Medalova will succeed her.
