The UK water sector faces mounting pressure over environmental performance, financial transparency, and executive pay. While water quality remains high, pollution incidents and sewage spills have drawn significant public and regulatory scrutiny. Recent years have seen record fines and growing calls for reform in governance, investment, and customer outcomes.
Each water provider is scored out of 100, weighted by these eight categories. Scores combine regulatory data (Ofwat, Environment Agency), customer feedback (CCW), financial disclosures, and environmental reports. All insights are sourced and referenced for transparency.
