UKAS vs Non-UKAS Certification

Understanding the Difference Between UKAS Accredited and Non-UKAS Certification

One of the most common questions organisations ask when considering ISO certification is:

"Do I need UKAS accredited certification?"

The answer depends on your customers, industry requirements and business objectives.

This guide explains the key differences between UKAS accredited certification and non-UKAS certification to help you make an informed decision.

What Is UKAS?

UKAS stands for the United Kingdom Accreditation Service.

UKAS is the UK's national accreditation body and is responsible for assessing and accrediting certification bodies that issue ISO certificates.

When a certification body is UKAS accredited, UKAS has independently assessed that organisation's competence, impartiality and certification processes.

Examples of UKAS accredited certification bodies include:

  • BSI

  • LRQA

  • SGS

  • NQA

  • Alcumus ISOQAR

  • British Assessment Bureau

  • Auva

What Is UKAS Accredited Certification?

UKAS accredited certification means:

  • The certification body has been assessed by UKAS

  • Audit activities are conducted in accordance with accreditation requirements

  • Audit durations follow recognised industry guidance

  • Certification decisions are independently controlled

  • Certificates carry accreditation marks

UKAS accredited certification is generally regarded as the highest level of certification assurance available within the UK.

What Is Non-UKAS Certification?

Non-UKAS certification refers to certification issued by organisations that are not accredited by UKAS.

This does not automatically mean the certification is poor quality.

Some non-UKAS certification providers may operate robust certification processes, whilst others may operate with significantly lower levels of oversight.

The quality of non-UKAS certification can vary considerably between providers.

Think of it like this, UKAS certified company’s have to audit you against the requirements of ISO/IEC 17021 where none UKAS do not and can audit you any which way they desire.

When Is UKAS Certification Recommended?

UKAS accredited certification is often recommended where:

  • Customers specifically require UKAS certification

  • Public sector tenders are being pursued

  • Supply chain requirements specify UKAS certification

  • International recognition is important

  • Large corporate clients require accredited certification

Many organisations choose UKAS certification because it provides the highest level of external assurance and is widely recognised throughout the UK and internationally.

When Might Non-UKAS Certification Be Suitable?

Non-UKAS certification may be suitable where:

  • Customers do not require accredited certification

  • Internal improvement is the primary objective

  • Budgets are limited

  • Organisations want independent external assessment without full accreditation costs

  • Certification is being used as a stepping stone towards future UKAS accreditation

The suitability of non-UKAS certification depends entirely on the organisation's objectives and customer requirements.

Does UKAS Certification Cost More?

In most cases, yes.

UKAS accredited certification bodies incur additional costs associated with accreditation, oversight and compliance requirements.

This often results in higher certification fees compared with some non-UKAS certification providers.

However, many organisations consider the additional investment worthwhile due to the increased recognition and acceptance of accredited certification.

Which Option Is Right For My Business?

Before choosing a certification route, consider:

  • Customer requirements

  • Tender requirements

  • Industry expectations

  • Budget

  • Long-term business objectives

  • Supply chain expectations

For many organisations, UKAS accredited certification is the preferred route due to its recognition and acceptance.

However, every organisation is different and certification should align with business objectives and stakeholder requirements.
