April 24, 2026 | Analyst: Robert C. Brears
CMA Redetermination: Financial Impact
| Regulatory Lever | Outcome / Impact | Strategic Signal |
|---|---|---|
| Average Bill (CMA Final) | £602 (2022-23 prices) | 2% uplift over Ofwat FD to bridge investment gap |
| Revenue Recovery | £463M (Sector-wide) | Reversal of Ofwat's "downside skew" in PR24 models |
| Allowed Rate of Return | 4.20% (Wholesale) | Increased from 3.97% to stabilize investor confidence |
| Blind Year Adjustment | Dec 2025 Recalibration | Real-time adjustment for 2024-25 actuals |
The 88 Recommendations: Governance Transformation
The July 2025 Independent Water Commission report fundamentally alters Anglian’s operating environment. The proposed merger of Ofwat, the DWI, and the Environment Agency into a single integrated regulator moves the sector toward a banking-style "Supervisory Approach."

Reform Recommendations
For Anglian Water, the recommendation for Mandatory Smart Metering and the creation of **Regional Water System Planning Authorities** shifts decision-making power from national regulators to regional ecosystems. This validates Anglian's drier-region strategy but imposes a continuous "supervisory loop" that limits the traditional five-year information lag.
