ISO 50001 Energy Management System

This Insight article sets out the reasons why you should consider implementing the ISO 50001 Energy Management System (EnMS) within your organisation.


A management system is defined as “the way in which an organisation manages the inter-related parts of its business in order to achieve its objectives.” These objectives can relate to a number of different topics, including energy. ISO 50001 is an EnMS which is based on the Plan-Do-Check-Act (PDCA) approach, depicted in the figure above. This enables organisations to review the outcomes of their energy policy and take appropriate action leading to continuous energy efficiency improvements.

In addition to enabling continuous improvements in energy performance, ISO 50001 also provides the following additional benefits:


ESOS Compliance


The implementation of a certified ISO 50001 EnMS that covers your organisations significant energy consumption (at least 90%) across buildings, processes and transport will ensure compliance with the Energy Saving Opportunity Scheme (ESOS).


Integrate ISO 50001 Energy Management System with Existing Systems


The ISO 50001 EnMS can Integrate with other or pre-existing standards such as the ISO 14001 Environmental Management System. A lot of the activities associated with the implementation of both of these systems are very similar. Therefore, an organisation can realise the benefits by implementing both in an integrated approach with minimal additional resource requirements.


Commitment to Energy Performance


Implementing a certified EnMS requires significant internal resources and is subject to rigorous external auditing. To certify an EnMS and maintain certification requires 5 separate external audits over 3 years. As such having a certified ISO 50001 EnMs demonstrates commitment to energy performance to any interested parties (customers, shareholders etc.).
