UKAS Certification Guidance

Do you need UKAS-accredited ISO certification?

Understand when accredited certification is required, when another route may be appropriate, and what to check before you commit.

Choose the right pathway

Not every organisation needs UKAS-accredited certification.

The right certification pathway depends on why you need certification, who is asking for it, the sector you operate in and the level of independent assurance required.

For organisations operating in regulated, safety-critical or complex supply chains — or where certification is required by a customer, tender or framework — UKAS-accredited certification may be the appropriate or specified route.

Our role is to help you understand the requirement before you commit to certification.

Decision guide

When should you choose UKAS-accredited certification?

A customer or major client requires it

Large organisations may specify UKAS-accredited ISO certification as part of their supplier approval process, contractual requirements or procurement criteria. If your customer states that suppliers must hold UKAS-accredited ISO 9001, ISO 14001, ISO 45001, ISO 27001 or another recognised certification, a non-accredited certificate may not satisfy that requirement.

You are tendering for contracts or frameworks

Public-sector bodies, principal contractors and major organisations may require evidence of independently accredited certification during pre-qualification or tendering. UK Government procurement guidance recognises accredited conformity assessment as a means of demonstrating supplier performance in areas such as quality, health and safety and environmental management. If certification is being obtained to support a tender, always check the procurement specification before selecting your certification route.

You operate in a safety-critical sector

Accredited certification can provide an additional level of confidence where failures could have significant consequences. In these environments, customers and supply-chain partners may require greater assurance that the organisation's management system has been independently assessed by a certification body operating within a recognised accreditation framework.

Your supply chain requires recognised certification

If you supply major contractors, government organisations, multinational companies or regulated industries, your certification may form part of their supplier assurance and risk-management process. UKAS-accredited certification provides an independently recognised route for demonstrating that your management system has been audited by an accredited certification body. This can be particularly important when entering new supply chains or demonstrating compliance during supplier pre-qualification.

Certification is specified within a contract

If your contract states that certification must be provided by a UKAS-accredited certification body, you need to select a certification body accredited by UKAS for the relevant certification activity and scope. Always check the wording carefully. A requirement for “ISO 9001 certification” is not necessarily the same as a requirement for “UKAS-accredited ISO 9001 certification”.

You need greater external recognition and assurance

UKAS is the UK's National Accreditation Body. UKAS assesses certification bodies against internationally recognised requirements covering areas including competence, impartiality and consistency. Using a UKAS-accredited certification body therefore provides an additional level of independent assurance over the certification process. For organisations where certification forms an important part of corporate governance, supply-chain assurance or commercial credibility, UKAS-accredited certification may be the preferred pathway.

Safety-critical sectors

Where additional assurance may matter.

Accredited certification can be particularly relevant in these environments.

  • Construction and infrastructure
  • Engineering and manufacturing
  • Aerospace and defence
  • Energy and utilities
  • Nuclear supply chains
  • Rail and transportation
  • Healthcare
  • Information and cyber security
  • Critical infrastructure
  • High-risk industrial environments
Certification and accreditation

What does UKAS accreditation actually mean?

There is an important distinction between certification and accreditation. Your organisation is normally certified to an ISO management-system standard, such as ISO 9001, ISO 14001, ISO 45001, ISO/IEC 27001 or ISO 22301.

UKAS does not normally certify your organisation directly to these standards. Instead, UKAS accredits certification bodies that carry out certification audits. Think of UKAS as providing independent oversight of the organisations conducting certification.

Legal and commercial requirements

Is UKAS certification a legal requirement?

Not necessarily. For many management-system standards, there is no general legal requirement for an organisation to hold UKAS-accredited certification.

However, accredited certification can become effectively necessary where it is required by a customer, written into a contract, specified within a tender or procurement framework, required by a particular scheme or regulatory arrangement, expected within a safety-critical supply chain, required for supplier approval or necessary to demonstrate an appropriate level of independent assurance.

This is why organisations should establish the purpose of certification before selecting their certification pathway.

UKAS or non-UKAS

Start with what the certificate must achieve.

The question is not simply which certificate is cheaper. The more important question is what your organisation needs the certificate to achieve.

If certification is required to satisfy a major customer, access a framework, qualify for tenders, enter a safety-critical supply chain or meet a specific contractual requirement, UKAS-accredited certification may be the correct pathway.

For other organisations, particularly those beginning their ISO journey or primarily looking to improve their management systems and demonstrate conformity, another certification pathway may be appropriate.

We help you choose

Establish exactly what you need before spending money.

The objective is simple: choose the right certification pathway for your organisation.

  • Who is asking for certification?
  • Does your customer specifically require UKAS-accredited certification?
  • Is certification part of a tender or framework?
  • Do you operate within a regulated or safety-critical sector?
  • Does your supply chain specify accredited certification?
  • Which ISO standard is appropriate?
  • What level of independent assurance does your organisation actually need?
