ISO 17025

The standard details the requirements testing/calibration laboratories and other testing organisations have to meet to prove that

- they operate a quality system,

- are technically competent and

- can generate technically valid results.

How do I get ISO 17025?

Don’t be put off by thinking it is too complex a thing to do. We aren’t saying it’s simple, but with us doing the bulk of the work for you, including managing the whole process, it is relatively straightforward.

There are the following stages to becoming and staying certified to ISO 17025:

  1. Comply with the relevant codes of practices and testing methods in your sector and ensure you follow them
  2. Establish a system that complies with the standard
  3. Make everyone aware of the system and any changes in ways of working that have come about
  4. Operate the system to
    a. Make sure it works efficiently
    b. Build evidence of compliance with the requirements of the standard
    c. Get staff familiar with it
  5. Engage UKAS to accredit the system
  6. Keep using the system once it has been accredited (to keep the certificate)

There is more detailed information below about the various stages you need to go through.

Your ISO 17025 certification journey

Group 161

Getting Started

  1. Provide a comprehensive briefing of what the standard asks you to do in simple to understand terms
  2. Approach UKAS to begin the process on your behalf as soon as we can. It is a drawn out process and they are typically booked out many months in advance.
  3. Begin to understand in detail how you operate
  4. Set a timetable and stick to it
  5. Decide what you want covered by the certificate – which sites, products and services. You can exclude some if you prefer.
  6. Put the right resources in place
  7. Identify specific roles and their associated authorities (an important aspect of the standard)
  8. Collect all existing documentation
  9. Establish a dedicated client portal on our collaboration and document sharing platform
  10. Begin establishing a system written from scratch for you
  11. Identify any equipment that needs to be maintained, controlled &/or calibrated by a UKAS accredited lab
  12. Consider software used & how correct outputs are assured
Group 162


  1. Establish a detailed project plan in our online project management platform (and stick to it)
  2. Complete UKAS’ application forms (there are 2 – a general application and a body-type specific form depending on what you do) & submit
  3. Decide what you need operationally
  4. Understand what the standard and any relevant codes of practice requires you to do
  5. Help you get your paperwork in order (accurate and complete records are vital).
  6. Do a gap analysis
  7. Implement the system, ensuring all requirements are met:
    a. System management
    b. Technical requirements
    b1. Human resources
    b2. Testing & calibration methods and methods validation
    b3. Equipment
    b4. Measurement traceability
    b5. Assuring the quality of results
  8. Brief staff on what they need to know & do
  9. Conduct an all clause internal audit (to same detail as UKAS will)
  10. Address any issues found during audit
  11. Carry out a management review
Group 163


ISO 17020 is an accredited standard, which means that in the UK only UKAS can audit you and issue a certificate. Beware, they operate on long lead times, so

  1. We approach them right at the start of the project
  2. When ready, submit the completed system for desktop review by UKAS
  3. Decide with you if you would like a pre-assessment visit by UKAS. We recommend not doing so.
  4. Undergo initial assessment.This is a comprehensive audit of documentation (especially records), compliance to the standard, and compliance to operational procedures and codes of practice where applicable (such as HSG 264 for asbestos management).
  5. Address the findings (there always are, that’s just how UKAS is) and submit evidence proving closure of the issues.
  6. Close out initial assessment
  7. Brief you on post-certification activity
  8. Support you during the 6 month surveillance audit (if required) (1)

(1) The certificate is valid for 4 years. 6 months after being initially accredited, UKAS returns to complete the first surveillance audit.

Just how hard is it?

There is no escaping the fact that as they are accredited standards, UKAS is very thorough in their auditing of your system, and are usually very knowledgeable in your sector. You do have to be precise in everything you do and say. You must make sure documentation is complete and accurate, and that staff absolutely follow operational processes.

However, it can be done and Episode will make the journey as smooth as possible, based on our previous experience of helping clients through the process.

Will it create red tape and take too much time?

Done wrong, absolutely. Too many systems we see have a form or document to cover every aspect of the standard. That’s the easy way to build a system, and an equally easy way to cripple you operationally. You know when this is the case when you spend a  month “updating” (i.e. creating false) records, etc. before the auditor next comes.

Done right, as we will make sure it is, the system should be at the core of how you work. Remember, we make ISO work for you, not the other way around.

How long will it take?

It is difficult to give precise timescales, as it depends on a number of things such as how complex the business is, how close you are to complying with the standard already, and so on. We recommend planning for it taking at least 3 months.

Why should I choose Episode?

For a fixed cost we will do as much of the work as possible, and guarantee certification. We do as much work as we can onsite with you, and we have several clients that have been through the UKAS accreditation process with us.

Episode has worked with over 40 clients, many of whom have more than one standard they comply with (one has 5). All have been successfully certified and many subsequently ask us to help them maintain certification, and get more out of the system.

How much will it cost?

There are the following costs that will arise

  1. External consultants

Episode always gives a fixed fee proposal for a project, and we include guaranteed certification. A typical ISO 17025 project is about £9,500, but this does depend on the size and complexity of your business.

  1. Accreditation costs

UKAS costs are typically £10,000 plus. You can save money by not doing the (optional) pre-assessment visit (See comments in accreditation above).

  1. Internal business costs.

This very much depends on what you do, and what needs to be done to comply (such as have equipment calibrated by a UKAS accredited lab, train staff to professional qualifications, etc.

What is quality management and ISO 17025?

ISO 17025:2017, General requirements for the competence of testing and calibration laboratories,  is based on, and is intended to compliment, ISO 9001, the ISO standard for quality management systems for any organisation. ISO 17025 in simple terms says there are specific expectations and requirement for testing & calibration environments that are therefore mandatory in a lab’s quality management system. As ISO 9001 is the general standard, laboratories which meet the requirements of ISO 17025 also operate in accordance with the requirements of ISO 9001 that are relevant to calibration and testing activities.

It enables laboratories to demonstrate that they operate competently and generate valid results, thereby promoting confidence in their work both nationally and around the world. It also helps facilitate cooperation between laboratories and other bodies by generating wider acceptance of results between countries. Test reports and certificates can be accepted from one country to another without the need for further testing.

The standard lays out the elements of your business management system that must be in place, such as impartiality and independence, structural and staff qualifications requirements, facilities and equipment, selection, verification and validation of methods, sampling procedures, metrological traceability, and so on. There is special emphasis on the reporting of results.

When done correctly, gaining and maintaining ISO certification is not as complicated as most think. Trust Episode to make ISO work for you, not the other way around.
