WHAT IS ISO 50001?

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

Certification to this standard 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 allow give an organisation full compliance with the Energy Saving Opportunities Scheme (ESOS) legislation


It’s 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.

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.


If you already have an ISO 14001 environmental management system in place, then you are already on route to ISO 50001 compliance.


Certification to ISO 50001 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.



  • Reduced operating costs. Significant financial savings can be achieved through increased energy efficiency (OFGEM forecast energy prices to rise by at least 20% by 2020).

  • Improved energy efficiency. ISO 50001 is the most robust energy management system, enabling you to make continual improvements to become as efficient as possible.

  • Reduced carbon footprint. Reduce your carbon footprint and people will respond positively to your organization.

  • Legal compliance. Understand how statutory and regulatory requirements impact your organization and stay on the right side of the law.

  • Proven business credentials. Independent verification against recognised standards speaks volumes andenhances your brand.

  • Ability to win more business. Procurement specifications require certification as a condition to supply,so certification is essential

  • ESOS energy assessment compliance (UK). DECC has confirmed that accredited ISO 50001 certification will contribute to ESOS compliance.

“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


Application for registration is made by completing the ISO 50001 Quote Request Form. This provides information about your organization so we can accurately define the scope of assessment.

Assessment to ISO 50001 is undertaken by NQA - this consists of two mandatory visits that form the Initial Certification Audit (explained below). 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.

Certification to ISO 50001 is issued by NQA and maintained through a programme of annual surveillance audits and a three yearly recertification audit.

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.


ISO 50001 Training - We provide CPD accredited training options to suit your needs and budget. These give you the skills to implement, audit and manage an effective energy management system.

Gap Analysis - We can undertake a gap analysis to help you determine the likely workload and timescale for implementing an energy management system that will achieve ISO 50001 certification. You can use this to plan implementation or brief a consultant.

Consultancy - We don't provide consultancy but we can help you choose a reputable consultant from the NQA Associate Consultant Register.
