Water and Flooding
Overview
Water policy spans two overlapping domains: the water sector (supply, sewage, environmental quality — regulated by Ofwat under PR24) and flood risk management (EA, Defra). A third thread — agricultural water quality — sits with Defra through ELM and the Target Delivery Plans. The Water White Paper (January 2026) proposes the most significant structural reform in decades.
Departmental positions
| Department | Position | Key commitment |
|---|---|---|
| Defra | Policy lead across all water domains | Water White Paper; single regulator; agricultural water quality 40% reduction by 2038 |
| EA | Operational flood management; water quality monitoring | £10.5bn flood programme; 98% asset condition target; £12m/yr farm inspection funding by 2029 |
| Ofwat | Economic regulator (proposed for merger/abolition) | PR24: £104bn investment; 44% storm overflow reduction |
| MHCLG | Intersection with planning (reservoirs; SDSs) | Non-water companies can build reservoirs (PIA 2025) |
Strategic coherence assessment
Low coherence in structure; high coherence in ambition:
- Three overlapping regulatory regimes (Ofwat/PR24, EA/FCERM, Defra/ELM) govern different aspects of water — coordination between them is not formally mapped in available documents.
- The Water White Paper proposes structural resolution (single regulator) but this is not yet in place; Transition Plan due 2026.
- The agriculture water quality target (Defra/ELM) and the storm overflow target (Ofwat/PR24) share the same catchments but are managed through entirely different systems.
- Flood asset condition is declining (92.8% vs. 98% target) despite record investment — suggesting investment is not keeping pace with demand.
Key tensions
- water-regulator-reform-pr24-uncertainty — Ofwat proposed for abolition during active PR24; regulatory uncertainty for £104bn investment
- sfi-simplification-water-quality — SFI changes may reduce ELM contribution to agricultural water quality target
Open questions
- What is the timeline for the Water White Paper Transition Plan (due 2026)?
- How does the proposed single regulator reconcile economic regulation (PR24-style price controls) with environmental regulation (EA/NE functions)?
- Is there a cross-government catchment management framework linking PR24 investments and ELM actions?
