ISO 50001:2018 Energy Management Systems

ISO 50001 is an international standard that specifies requirements for an energy management system (EnMS). It is based on the management system model of continual improvement used for other well-known standards such as ISO 9001 or ISO 14001. This makes it easier for organisations to integrate energy management into their overall efforts to improve quality and environmental management and provides organisations with the requirements for energy management systems. The standard provides an internationally recognised framework to manage and improve an organisation's energy performance.

What are the benefits of ISO 50001 Certification? 

In addition to the widely recognised benefits of conformity with ISO 50001 such as cutting energy consumption and cost and reducing exposure to rising costs.  The Energy Saving Opportunities Scheme (ESOS) Regulations, introduced in 2014, permit organisations to use UKAS accredited ISO 50001 Certification as an alternative to producing an ESOS report.

Third party Certification can be used to demonstrate your commitment to reduce your organisation's carbon footprint to interested parties and stakeholders as well as to show conformity to applicable legal requirements. Other benefits include achieving your energy targets by reducing your energy bills and increasing the energy efficiency of your organisation.
