What is an ISO audit?

An ISO audit is a critical review process designed to ensure an organisation's compliance with international quality, security, and safety standards. This process assesses whether management systems are not only in place but are also effective and adhere consistently to global ISO standards. By conducting an ISO audit, organisations can confirm that their processes are accurately documented, properly implemented, and maintained effectively.

Key Objectives of an ISO Audit:

Assessment of Compliance: Ensures the organisation's processes align with ISO standards, regulations, and statutory requirements, promoting a culture of continuous improvement.

Verification of Process Implementation: Confirms that procedures are applied uniformly across the organisation, enhancing operational efficiency.

Identification of Improvement Opportunities: Highlights areas where processes can be optimised and helps refine operational strategies to better meet customer and market demands.

Enhancement of Organisational Efficiency: Focuses on fine-tuning procedures and working conditions to boost overall productivity and quality of output.

  • How much does ISO certification cost?

    ISO certification costs depend on various factors including the ISO standards you’re applying for. The cost typically depends on your organisation's size and the amount of work you've already done towards certification. Seeking certification for multiple standards simultaneously might increase costs, but TÜV SÜD may offer discounts in these cases. Various factors which contribute to your total ISO certification costs could be: 

    • Organisation size
    • Business sector/industry
    • Annual revenue 
    • Number of employees 
    • Internal audit costs 
    • Surveillance audits 
    • Maintenance and recertification costs

  • How long does it take to get ISO certified?

    ISO certification typically takes between 3 and 6 months from implementation to registration. For large, complex organisations, it could take up to 12 months. Different standards require more time for certification than others. It also depends on how closely your existing systems align with ISO requirements and the thoroughness of your documentation. 


  • The ISO Audit Process Explained

    1. Pre-sales & Order Confirmation

    TÜV SÜD prepares individual offer/s based on the questionnaire/s submitted. The organisation must give us order confirmation.

    2. Audit Planning

    TÜV SÜD reviews your questionnaire to develop the audit plan and coordinates the audit process.

    3. Audit Action

    TÜV SÜD conducts Stage 1 audit on-site, updates original audit plan, and completes certification audit Stage 2.

    4. Any Deviations?

    Your organisation implements corrective measures to address non-conformances identified by TÜV SÜD.

    5. Certification Issuance

    A positive decision by TÜV SÜD allows your organisation to use the certificate and the certification mark.

    6. Surveillance Audits

    Annual audits and recertification audits required to maintain certification validity.




Management systems help organisations large and small improve business operations, reduce risk and achieve a competitive edge. Management systems such as ISO 9001 and ISO 45001 provide a framework for companies to assess their processes.

Management system auditing and certification involves independent experts assessing your processes to discover areas of improvement. A certification confirms the compliance of your processes to relevant standards.

The International Organization for Standardization (ISO) recently amended its Management System Standards (MSS) to emphasise climate change. Organisations implementing these standards must now acknowledge climate change's impact on their operations and actively engage stakeholders, such as customers and communities, to address this critical external issue.

ISO 9001 - Quality Management Systems
ISO 9001 provides a quality management system (QMS) that companies use to ensure the quality of their products and services. The QMS is based on seven quality management principles (QMPs) to assess performance and quality policy: customer focus, leadership, engagement of people, process approach, relationship management, evidence-based decision-making, and improvement. In an ISO 9001 audit, TÜV SÜD will conduct a documentation review audit before carrying out an on-site audit to see if your actual activities comply with ISO 9001 requirements and company records.

ISO 14001 - Environmental Management Systems 
ISO 14001 is the foremost international standard for environmental management systems (EMS) and is suitable for organisations of any size. It provides a systematic framework for integrating environmental management practices by supporting environmental protection, pollution prevention, waste minimisation, as well as energy and materials consumption reduction. An ISO 14001 audit is conducted to ensure that your organisation’s environmental management system complies with the requirements of ISO 14001 and the applicable environmental regulations. It also reviews whether the EMS has been effectively implemented and maintained. 

ISO 27001 -  Information Security Management

ISO/IEC 27001 is the leading international standard for information security management systems (ISMS). By implementing and maintaining an ISMS to protect data that is crucial to the business, you can mitigate risk and ensure stable operations, and provide confidence to stakeholders and customers. 

TÜV SÜD will audit your organisation’s ISMS to see if it complies with ISO 27001 and other regulatory requirements. Auditors will rigorously evaluate your ISMS, focusing on confidentiality, integrity, and availability of data. By identifying weaknesses and recommending improvements, ISO 27001 audits help improve data protection and safeguard against potential cyber threats. 

ISO 45001 - Occupational Health and Safety

ISO 45001 is an international standard that specifies requirements for an occupational health and safety (OH&S) management system, which is intended to improve the H&S of employees and other personnel. The ISO 45001 audit process will review your organisation’s OH&S management systems to assess compliance with the requirements of ISO 45001 and applicable OH&S regulations.  Auditors will also review whether the systems have helped to create safer working environments and prevent workplace accidents.
