Our laboratories

Our analytical services for the microbiological and chemical testing of waters, wastewaters, solids and air samples are available across the UK.

Our three UKAS & DWTS accredited labs are based in the North East and South East of England. The focus of each laboratory is outlined below:

  • Howdon (Newcastle):

    Organic chemistry, inorganic chemistry and metals analysis of potable waters, wastewaters, solids and air samples.

  • Horsley (Northumberland):

    Microbiological testing of potable waters for coliforms, E. Coli, total viable counts (TVC′s), cryptosporidium, legionella and an extensive list of accredited drinking water microbiology tests.

  • Hanningfield (Essex):

    Analysis of drinking waters for a broad range of microbiological tests, plus inorganic chemistry and biology analysis.

    We have a dedicated overnight courier service which uses refrigerated vehicles to transfer samples between each of our laboratories. This helps them function as a single integrated unit, ensuring the full range of our analytical services is available to you irrespective of your location.

    Across our three analytical laboratories:

  • We analyse over 300,000 samples per year
  • Conduct over 1.2 million tests per year
  • Have over 150 methods accredited to ISO 17025, DWTS, and MCERTS.
