Who are My Tap Water?
My Tap Water make UK water quality data accessible to everyone. They aggregate the annual compliance data published by all UK water companies into a single postcode lookup, covering more than 1,600 water supply zones and over 30 tracked parameters across England, Wales, Scotland and Northern Ireland.
Water quality is one of the few things about a home that almost nobody checks before they buy, yet it affects daily life immediately. Hard water shortens the life of boilers, showers and washing machines. Chlorine affects taste. Nitrates, lead and PFAS are the parameters buyers most often ask about, and the answers are already published, just buried in regulatory reporting nobody reads.
We have partnered with My Tap Water so you can check any postcode here for free, and order the full report when you want the detail in one clear document.
