How it works
Test your water at home in about a minute. Here is how the strips work, what each one tests and how we explain your results.
Fill a glass
Fill a clean glass with the water you want to test.
Dip a strip
Dip one strip for 2 seconds, then shake off the excess.
Match the colours
Wait about 30 seconds, then compare against the colour chart.
Check online
Scan the QR code for an explanation of each reading.
Bacteria test (if your pack has one): add 2 ml of your sample to the sachet, seal it and lay it flat. Read the colour after 48 hours at room temperature, or 24 hours at 37°C. Purple means no coliform bacteria grew. Yellow means they did.
What it tests
20 readings, one strip
Twenty readings from a single strip, plus bacteria with the optional rapid test. Every one explained in the results portal.
Strips give a banded reading, not a laboratory number. For PFAS, a certified lead figure or a formal bacteria count you need a UKAS lab test, and the portal tells you when that applies.

The online results portal
Every reading explained, not just a colour
Other strips leave you holding a bottle and squinting at a chart. WaterKit comes with an online results portal: photograph your strip on its chart or tap the colours you matched, and it turns 20 readings into a plain-English report you can save, share and compare next time.
-
Photo mode or chart mode
Photograph the strip on its chart and the portal reads the pads for you, or tap the colours you matched.
-
Compared with the UK limit
Each reading is set against the limit in the UK drinking water regulations where one exists, and marked normal, watch or action.
-
What to do next, in plain English
Run the tap, re-test, call your water supplier or confirm with a lab: the report says which, and in what order.
-
Save, share and compare
Keep your reports on your phone, send a link to a plumber or landlord, and see what changed since last time.
