Anglian Water: water quality and hardness
Anglian Water is a regional drinking-water and wastewater supplier. Its drinking-water checker is the appropriate route for identifying the local report rather than assuming that every address in a county shares the same water.
An independent WaterGrade guide. Local readings vary by source area and date.

How Anglian Water reports on your water
The supplier’s report tool includes hardness and a more detailed drinking-water report. That fuller report is useful when you need a specific substance, sampling context or an original document to compare.
Search your postcode, then choose “I want a full Drinking Water Quality Report for this area”. Keep the zone name, report year and units. Until a validated import is available here, use that original result with our report-reading and conversion guides.
Company information and source context ↗What WaterGrade currently holds
Local measurements from Anglian Water have not yet been imported and approved. This page explains its report tools and helps you interpret the original data; no hardness number or quality score is inferred.
Is the water hard or soft?
Check the figure for your supply zone. A company can deliver water from different sources, so a single average can give the wrong appliance setting for your home. Hardness describes dissolved minerals; it is not a safety rating.
Our local cards use mg/l as calcium carbonate (CaCO₃). Keep the original unit and reporting period when comparing results. Supplier labels can use different hardness bands.
What do the quality results tell you?
Read each parameter with its units, sample count, range and reporting period. A mean below a reference limit does not establish that every sample complied. A “less than” result is not an exact concentration.
Company-wide performance, local zone results and water at an individual tap are different levels of information. Historical exceedances need the supplier’s investigation context; they are not automatically a current incident.
Understand the measurements in a water reportFind your local source-area report
Use the exact area name from the supplier’s checker. Older areas can have been renamed or replaced. Each card keeps the hardness period separate from other quality data.
Start with the supplier’s original report
- Open the official quality route and find your postcode or supply zone.
- Note the reporting period, hardness unit and any explanation of changes.
- Use our converter and report guide to interpret it. Report an unclear or missing source to WaterGrade.
Has the water changed over time?
Compare the same named area, metric, units and kind of reporting period. A new download date is not a new sample. Renamed zones or overlapping rolling windows need extra care before drawing a trend.
We do not yet hold a comparable annual hardness series for this supplier. We do not draw a trend from a single edition or overlapping rolling reports.
