Accreditations & Certifications

Why is Accreditation important?

Accreditation demonstrates the technical competence of laboratories offering testing, calibration, certification and inspection services against internationally recognised standards. Dealing with an accredited laboratory ensures excellent service and quality of work.

H&D Fitzgerald has been an accredited laboratory for over 30 years. Our principle accreditations are held with two external and internationally recognised organisations, UKAS and ISO.


The United Kingdom Accreditation Service (UKAS) is the sole national accreditation body recognised by the British Government for ISO 17025. It assesses, against internationally agreed standards, organisations that provide certification, testing, inspection, and calibration services.

Accreditation by UKAS demonstrates a laboratory’s competence, impartiality and performance capability, and ensures that its measurements are traceable to recognised national standards held by the National Physical Laboratory or other national laboratories.

Please visit the UKAS website to see our current schedule of accreditation.

ISO 17025

Our second principle accreditation is with the International Organisation for Standardization (ISO), with which we hold accreditation to ISO 17025 which covers our measurement capability.

ISO is the world’s largest developer and publisher of International Standards, and is formed of a network of the national standards institutes of 162 countries, one member per country, with a Central Secretariat in Geneva, Switzerland. See for more information.
