Leadership Change After Rating Downgrade
Yorkshire Water announced that chief executive Nicola Shaw will leave the post on January 1, 2027. The company scheduled an announcement for Friday, October 30 that Shaw would step down after almost five years at the helm. Nicola Medalova, a chartered environmental health officer and former National Grid executive, will join as CEO-designate on November 2 and assume the role in 2027. The shift follows the Environment Agency’s downgrade of Yorkshire Water to a one-star rating, the regulator’s lowest score.
02
Background & Context
The Environment Agency’s annual Environmental Performance Assessment grades England’s nine water and sewerage companies on river, stream and sea pollution. Yorkshire Water fell from a two-star rating last year to one star, placing it among four firms classified as “poorly performing.” Companies with a one-star rating are automatically barred from paying executive bonuses under rules introduced last year.

Data & Statistics
- Pollution incidents recorded in 2025: 260 – a rise of more than 70 % from 151 in 2024 and the highest total since 2011.

- Ofwat fined Yorkshire Water £47 million in 2024 for historic sewage leaks and £1.215 million for two 2025 prosecutions.
- The company has pledged £8.3 billion of investment between 2025 and 2030, including £1.5 billion to cut storm-overflow discharges.

04
Official Statements & Responses
A Yorkshire Water spokesperson said the firm’s environmental performance “was not good enough” and that customers would be disappointed. Chair Jon Lewis thanked Shaw for securing £500 million of new shareholder equity and committing an additional £600 million, enabling the company’s largest investment programme to date. The Environment Agency noted that Yorkshire Water failed to complete six legally required environmental schemes on time but achieved 99 % compliance for permitted discharges in 2025.
05
Criticism & Opposition
Shaw’s undisclosed payments attracted criticism from regional leaders and campaigners. Reports highlighted that her total earnings, including the £1.3 million shareholder payments, reached £1.392 million, prompting public outcry amid rising water bills and worsening environmental performance.
06
Conflicting Reports & Gaps
Sources differ on the total number of 2025 pollution incidents: most cite 260, while one outlet reports 335 incidents, including 13 serious cases. The discrepancy has not been reconciled in publicly available regulator data.
07
Why It Matters
The one-star rating triggers an automatic ban on executive bonus payments, adding financial pressure to a company already facing fines and public scrutiny. The leadership change occurs as the sector confronts heightened regulatory expectations, ongoing public pressure over sewage discharges, and the need to deliver on a multi-billion-pound investment plan. Stakeholders will watch whether the new chief executive can translate the pledged spending into measurable improvements in pollution control and service reliability.

- “There is much more to do, and we will be open about where we are making progress and where we are not. The test for us isn’t simply how much we spend. It is whether customers and the environment see better results.” — Yorkshire Water, non-executive director
