ISO 50001 Accreditation


ISO 50001 specifies requirements for establishing, implementing, maintaining and improving an energy management system. The purpose of ISO 50001 is to enable an organisation to achieve continual improvement in their energy performance through a systematic approach.

ISO 50001 specifies requirements applicable to energy use and consumption, including measurement, documentation and reporting, design and procurement practices for equipment, systems, processes and personnel that contribute to energy performance.

The ISO 50001 standard is based on the Plan-Do-Check-Act methodology which encourages the organisation to put in place actions to reduce and monitor energy use. The following steps form the
basic structure of ISO 50001.

  • Plan: Conduct the energy review and establish the baseline, energy performance indicators (EnPIs), objectives, targets and action plans necessary to deliver results in accordance with opportunities to improve energy performance and the organization’s energy policy.
  • Do: Implement the processes.
  • Check: Monitor and measure processes against energy policy and objectives, and report the results or take any necessary corrective action.
  • Act: Take actions to continually improve energy performance.



  • Increase energy efficiency thus reducing cost
  • Reduce environmental impacts
  • Increase level of assurance of legal and internal compliance
  • Identify the types of variables that are affecting energy use
  • Increase profits through reducing excessive costs
  • Uphold best practices by reinforcing proper energy management processes
  • Encourage commitment within the organisation by introducing a systematic approach on sustaining of energy efficiency


ISO 50001 Accreditation

TUV was the first certification body in Western Europe to become an approved body (accredited by the European State Body INAB) to issue organisations with ISO 50001 certificates. We are an accredited certification body which provides International Organization for Standardization (ISO) management system certification and inspection services to organisations globally.

Accreditation is the process by which a certification body is recognised to offer certification services. In order to become accredited, TUV is required to implement a quality management system which meets international standards. TUV is audited annually to ensure its services meet the exact requirements of the relevant accreditation standards.

ISO 50001 Energy Certification

As an accredited certification body we certify companies to the ISO 50001 standard. Companies are certified and not accredited to standards. TUV can certify your organisation in Ireland, Europe and globally to the energy management systems standard ISO 50001.

Once you sign up for ISO 50001 EnMS certification you will begin the audit process. Upon satisfactory completion of each of the audit stages you will be awarded the ISO 50001 energy management certificate. The standard lasts for three years and is subject to mandatory audits every year to ensure that you are still compliant. At the end of the three years when you decide to retain the ISO 50001 certification you will be requested to complete a reassessment audit in order to receive the standard for an additional three years.
