Energy Management

ISO 50001

ISO 50001:2018 is the International Standard for Energy Management Systems.

What is ISO 50001?


What is ISO 50001?

ISO 50001:2018 is the newly revised international standard for Energy Management providing the most robust framework for optimising energy efficiency in public and private sector organizations.

ISO 50001 certification demonstrates an organization’s commitment to continual improvement in energy management, allowing them to lead by example within their respective industries and ensure related legislative and regulatory requirements are met.

It will also provide organizations with a standard that ensures requirements are met for compliance with the Energy Saving Opportunities Scheme (ESOS) UK legislation.

We have certified a wide range of organizations in different sectors including EPS Pumping and Treatment Systems, ETDE at the Cabinet Office and Costa Coffee.

ISO 50001 has seen a 9.7% increase in worldwide certificates in 2020, showing the growth and importance of UKAS accredited certification in recent times. Statistics straight from the most recent ISO Survey.

Benefits of ISO 50001 Certification

Improve efficiencies icon

Improve efficiencies

Is ISO 50001 certification right for me?

ISO 50001 certification is right if you and your organization want to take control of the way you use energy and manage the related costs more effectively. It is particularly beneficial for organizations with significant energy expenditure.

If you already hold certification to ISO 14001, the ‘basic framework’ is already there and the benefits of ISO 50001 are within reach. If you already have an ISO 14001 environmental management system in place, then you are already on route to ISO 50001 compliance.

Transition to ISO 50001:2018

For those organisations who have already been through the transition process on either ISO 9001 or ISO 14001 you will be familiar certificates to the ‘old’ version will expire on 20th August 2021. 
Whilst this may seem a long way off, we recommend that an early start to the process would be beneficial. We at NQA recommend therefore starting to prepare for the transition as early as possible and plan properly to incorporate needed changes into your management system.

Specifically we suggest that you:

  • Ensure that relevant staff  within  your organization are trained and understand the  requirements and key changes to the standard.

  • Identify gaps which need to be addressed to meet the new requirements and establish an  implementation plan. Implement those actions and update your management system to meet  the new requirements.

  • Evaluate the effectiveness of implementation through internal audits and the NQA transition gap analysis form which will be available soon.

This standard is changing

ISO 50001 certification demonstrates an organization's commitment to continual improvement in energy management and several changes have been made to the 2011 version of the standard to bring it in line with the needs of today’s business environments. Organizations holding ISO 50001:2011 should be aware ISO 50001:2018 has now been published (21st August 2018) and the 3 year transition clock has started ticking.

The main change is the adjustment of the standard to align it with Annex SL the ‘high level structure’ as already seen in the 2015 versions of ISO 14001, ISO 9001 and the newly released ISO 45001 Health and Safety standard.

Other changes include normalization of environmental performance indicators (EnPIs) and associated energy baselines (EnB), clarification on the requirements of the energy data collection plan, and a general focus on ensuring the key concepts related to energy performance are clear and accessible for small and medium-sized businesses (SMEs).
NQA will be working towards the transition and, following the process undertaken for ISO 9001 transition in 2015 will be releasing guides, training and further information regarding the actual transition process and how it affects our clients.

“The certification process allowed us to have a full reassurance that the system we had implemented and the actions we were taking were on the right track and would support the continual improvement of our energy performance.” Costa Coffee / Whitbread Plc

Steps to Certification

  1. Step 1

    Complete a Quote Request Form so that we can understand your company and requirements. You can do this by completing either the online quick quote or the online formal quote request form. We will use this information to accurately define your scope of assessment and provide you with a proposal for certification.

  2. Step 2

    Once you’ve agreed your proposal, we will contact you to book your assessment with an NQA Assessor. This assessment consists of two mandatory visits that form the Initial Certification Audit. Please note that you must be able to demonstrate that your management system has been fully operational for a minimum of three months and has been subject to a management review and full cycle of internal audits.

  3. Step 3

    Following a successful two stage audit, a certification decision is made and if positive, then certification to the required standard is issued by NQA. You will receive both a hard and soft copy of the certificate. Certification is valid for three years and is maintained through a programme of annual surveillance audits and a three yearly recertification audit.
