Why test?

Clear water isn't necessarily simple water.

Many substances in water cannot be identified by appearance, smell or taste alone. Analysis measures them directly.

Six stages, each with the potential to influence what a laboratory measures.

  1. 01

    Source

    Geology and catchment characteristics

  2. 02

    Treatment

    Processes applied before distribution

  3. 03

    Distribution

    Mains network and residence time

  4. 04

    Building

    Storage, risers and internal systems

  5. 05

    Plumbing

    Pipe material, solder and fittings

  6. 06

    Tap

    The point where measurement matters

Your water changes on its journey

Water reaches a tap through a chain of stages, and each one can influence its characteristics. Measuring at the tap describes what you actually drink, which a source-water summary cannot.

Older plumbing

Building pipework, solder and fittings are in direct contact with water, sometimes for hours at a time. In older properties this contact is one of the main reasons a result at the tap can differ from a result at the treatment works. Testing identifies whether it is happening in your building.

Emerging contaminants

Scientific and regulatory interest in PFAS and microplastics has increased, and analytical methods have improved alongside it. That combination means compounds can now be measured at concentrations that were not routinely reported a decade ago. Measurement, not speculation, is the useful response.

Water filters

Filters differ substantially in what they reduce. Understanding which parameters a product has actually been tested against — and under what conditions — is more informative than a category label on the packaging.

Evidence over assumptions

We do not use alarm to sell analysis. UK mains water is treated and regulated, and a laboratory result is simply more specific: it tells you what is present in your water, in your building, at the moment of sampling.

Measure. Then decide.

Laboratory analysis turns a question about your water into a set of numbers you can act on.
