Rising bills
Ofwat's PR24 final determinations set company investment plans and bill impacts for 2025-30. Customers may still challenge errors in individual bills.
Industry watch
See the broader pattern, then check your own facts.
Industry data can explain why customers are concerned. It does not decide an individual bill. Use it for context, then use your own evidence for your own complaint.
Current picture
Bill pressure, complaint pressure, trust pressure.
2025-30
Ofwat's PR24 period allows large investment and large bill increases across the sector.
16,000+
complaints handled by CCW during 2025, up 51% compared with 2024 according to CCW's Water Matters 2026 release.
44%
of customers in CCW Water Matters research published in 2026 said charges were fair.

Rules and reviews
The regulatory system is changing.
- The Water (Special Measures) Act 2025 gave Ofwat new powers on performance-related executive pay, governance, consumer involvement, and senior-leader fitness standards.
- Ofwat says its first-year bonus rule blocked more than GBP 4m of potential performance-related pay.
- The Independent Water Commission recommended a new integrated regulator for England and a similar approach in Wales, with stronger consumer advocacy and regional planning.
Broad spectrum
What customers are seeing across the system
These categories help the site stay fair: not every company or case is the same, but the pattern of concern is broad.
Escalating complaints
CCW complaint data shows rising household complaint escalation. Billing, charging, and service handling remain practical customer issues.
Environmental performance
Environment Agency and Ofwat reporting shows serious concern around pollution incidents and wastewater performance.
Regulatory action
Ofwat has issued or secured major enforcement outcomes for some companies. Penalties and redress are not the same as ordinary bill corrections.

Primary data sources
Use industry data as context, not as a shortcut.
A company fine, pollution report, or sector complaint trend can support public concern. Your bill complaint still needs your bill, readings, correspondence, and a clear requested outcome.
