Why it's on ClimateTicker

Affinity Water is the UK's largest water-only company and operates in a sector intrinsically tied to climate adaptation — managing groundwater abstraction, drought resilience, leakage reduction, and catchment protection in a water-stressed region. Its core business provides genuine adaptation value, but it is not a net emissions reducer: it is an energy-intensive utility with significant Scope 2 and Scope 3 footprints and no SBTi-validated targets. Investors should weight its adaptation role positively but apply scrutiny to unvalidated net-zero claims and a recent regulator-imposed penalty for environmental underperformance.

adaptationAffinity Water earns revenue through regulated water bills set by Ofwat under a five-year Asset Management Period (AMP) framework, abstracting, treating, and distributing drinking water to approximately 3.9 million people across south-east England and the London commuter belt; it holds no wastewater or sewerage responsibilities.

lowCustomer satisfaction at sector low; C-MeX penalties
