ISO 50001 is an international standard based on the management system model of continual improvement also 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.

CIBSE Certification is a UKAS Accredited Certification Body 

In addition to the widely recognised benefits of compliance with 50001 such as cutting energy consumption and cost and reducing exposure to rising costs.  The ESOS Regulations introduced in 2014, permit organisations to use UKAS accredited ISO 50001 Certification as an alternative to producing an ESOS report. This is consistent with ESOS in all EU member states, making it an ideal compliance tool for organisations operating in more than one member state.
