Correspondence from Mark Thurston, CEO, Anglian Water, regarding Reforming the water sector inquiry, dated 3 June 2025

From: Environment, Food and Rural Affairs Committee

Inquiry: Reforming the water sector

Summary

Mark Thurston, CEO of Anglian Water, responds to the Environment, Food and Rural Affairs Committee's follow-up questions on water sector reform. The letter addresses remuneration governance, communications spending (78p per household annually), asset replacement rates (increasing water mains renewal from 0.13% to 0.5% in AMP8), water poverty support (doubling cross-subsidy to £24 and reaching 12.7% of customers on Priority Services Register), and data transparency initiatives.

Key findings

  • Anglian Water is implementing an Annual Bonus Plan post-AMP7 with 50% environment, 20% customer, and 30% infrastructure weighting, aligned with Ofwat recommendations
  • Communications spending averaged 78p per household per year over five years; no legal fees spent on actions against regulators
  • Water mains replacement rate increasing to 0.5% annually in AMP8, but company argues sustainable performance requires 0.9% (European average) and Ofwat acknowledges need for 0.6–0.8%
  • Water poverty support expanded: cross-subsidy doubled from £12 to £24 in AMP8, providing up to 50% discounts for 230,000 customers and new Medical Needs Discount funded by owners
  • Priority Services Register enrollment at 12.7% (May 2024), exceeding industry average of 5–6%; 9-month period signposted £18.3m in unclaimed benefits to customers

Notable line

We believe this is replicated across other asset classes and therefore we need to see sustained and significant increases in civil engineering asset renewal.
