What is UKAS?

UKAS is an abbreviation for United Kingdom Accreditation Service and is the only accredited body that is authorised to assess the competence and ability of organisations who provide certification for testing, inspection and calibration services.

UKAS approved organisations like Stevens Traceability must undergo a long and tough process to become accredited, this includes having management, policies, and processes in place, together with passing an assessment of competence. The reason for such a strict assessment process is to ensure that UKAS accredited bodies provide customers with a high level of service with the assurance of best practice.

What does UKAS cover?

UKAS accreditation covers a broad range of calibration activities including:

  • Temperature and Humidity
  • Pressure, Vacuum, and Flow
  • Optical
  • Electrical Calibration
  • Radiological Calibration
  • Accelerometry
  • Magnetics
  • Acoustics
  • Density
  • Dimensional
  • Force
  • Hardness
  • Mass
  • Volume
  • Torque

At Stevens Traceability we specialise in calibration of non-automatic weighing machines.

Why have UKAS calibration?

Achieve compliance, cost savings, and quality

Carrying out UKAS Calibration determines measurement equipment performance as part of a robust quality control system. With routine equipment UKAS calibration and adjustment, you can measure safely, ensure compliance and avoid the costs of inaccurate measurements.


The United Kingdom Accreditation Service (UKAS) is the only authorised body that can assess a company’s compliance to ISO17025:2017 and award accreditation status.  ISO17025 is the international standard that defines what is required of a laboratory to demonstrate the technical competence of its personnel.  It also requires the availability of all technical resources necessary to produce reliable data and results for a defined set of tests, measurements or calibrations.

The key benefits are:

  • Organisations can save time and money by selecting an accredited and therefore a competent supplier.
  • Accredited organisations carry out reliable measurements, tests, and inspections in accordance with best practices in or to limit product failure and reduce downtime and control manufacturing costs.
  • Accreditation to internationally-recognised standards can provide a competitive advantage and facilitate access to export markets within the EU and beyond. (see international system)
  • Using an accredited body to carry out an independent evaluation helps demonstrate due diligence in the event of legal action.

Stevens Traceability provides nationwide UKAS and BSI accredited on-site service and support including standard and UKAS calibrations. If you’d like to discuss your calibration needs, please get in touch with our service team on 01254 685200.
