Regulator, consumer body, government, court, official company document, or ASA ruling where possible.
Source discipline
Simple claims need careful evidence.
Use this page to understand how to read the handbook. Strong claims should stay tied to a source, date, body, company, issue, and outcome.
Claim rules
How to judge a claim.
A fine, complaint trend, or performance rating is not treated as proof that one household bill is wrong.
A source about a company, year, region, or regulator is not automatically evidence about a different bill, year, or issue.
Traffic light
How to read a finding.
The source directly says the company, issue, date, and outcome.
The source supports concern, but does not decide a household case.
Be careful with unsourced allegations, merged events, or claims where the source does not support the wording.
Reader checks
Check evidence before relying on it.
Use regulator, consumer body, government, court, or official ruling pages first.
Look for the publication date and the reporting year before using a statistic or rating.
Do not merge fines, investigations, complaints, and bill disputes.
Confirm whether the source is about the water company, wastewater company, regulator, or consumer body route.
Use strong language only when the source directly supports it. Let source links carry extra depth.
