Use for high bills, readings, leaks, rebates, payment support, and poor customer service.
Regulators and contacts
Use the body that can actually act.
Water complaints split across different organisations. This page separates bill and service complaints from pollution, drinking-water quality, information rights, advertising claims, and regulatory issues.
Do not send everything to every body.
For most personal household bill disputes, the company first and CCW second is the practical route. Ofwat says it does not deal with individual consumer complaints about water companies or individual bills except for a small number of disputes within its remit.

Match the issue before sending it.
Use for drinking-water taste, odour, colour, quality, or safety concerns.
Use for sewage, pollution, dead fish, illegal abstraction, or environmental harm.
Use for issues Ofwat can determine or investigate, not routine personal bill casework.
Use when an official information or environmental information request has gone wrong.
Use for misleading environmental marketing claims with screenshots and dates.
