ISO 50001

ISO 50001 provides a systematic approach to
reducing energy consumption, increasing sustainability
and complying with legislations such as the Energy Savings
Opportunity Scheme (ESOS)



ISO 50001 is the international standard for energy management and is based on the management system model of continual improvement used for other well-known standards such as ISO 9001 or ISO 14001. Whilst this is not a mandatory standard, many organisations decide to implement ISO 50001 solely because of the benefits it provides. ISO 50001 provides a systematic approach to reducing energy consumption, increasing sustainability and complying with legislations such as the Energy Savings Opportunity Scheme (ESOS).

ISO 50001 can be used by any business, large or small and helps organisations implement a flexible and robust energy management system (EnMS). The international standard outlines energy management practices that not only save your organisation money but sustains those savings over time. Organisations that make a commitment to improvement by following the principles of good management frequently report achieving significant energy savings often without investment in new technology.

There are also a number of indirect benefits that organisations receive from achieving ISO 50001 certification which vary from industry to industry and with the type of improvements made. Typical examples include reduced waste production, compliance with applicable legal requirements, improved control of operations leading to improved productivity and improved comfort levels in buildings.


Reduced cost of energy consumption
Reduced environmental impact of operations through energy savings and reductions in CO2
Improved operational performance of equipment
Improves data accuracy and control of energy consumption
Compliance with applicable legal requirements
Increased labour efficiencies and delivery of core offerings


We can support our clients throughout the journey to achieving certification - from the initial stages of energy data collection and employee engagement through to ISO 50001 certification and maintaining a compliant EnMS.

Following an initial consultation meeting, our Chartered Energy Managers will review your energy consumption and work with your organisation to design a package that is reflective of your business objectives. Drawing on the expertise and skills of our Energy Data Analysts from our Technical Energy Centre, we will assess and identify areas of high consumption, behavioural patterns and put forward recommendations for improvements.

Depending on client requirements and the type of improvements adopted, we can provide various turn-key solutions and in-house support to deliver a wide range of energy saving initiatives including building performance optimisation, behavioural change and project management.  Our ISO 50001 Lead Auditors will then guide you through the next stages to achieving certification and where required, provide support to maintaining this standard going forward.

what is ISO 50001

ISO 50001 is based on the management system model of continual improvement. The Plan, Do, Check, Act (PDCA) cycle is the operating cycle of ISO management standards used for other well-known standards such as ISO 9001 or ISO 14001. The idea behind an EnMS is to have a systematic approach that will be sustainable and nurture a culture of continuous improvement.

9 Tips to Getting Started

1. Keep it Simple
Don’t complicate things. Use simple language: Plan, Do, Check, Act (PDCA).

2. What, Where, When?
Determine what energy is being used; where and when and identify areas of significant energy use.

3. Get Everyone Involved
We all have an impact on energy management which is why it is important to get everyone in the organisation involved.

4. Engage and Motivate
An Energy Management System is only effective along as you have an engaged workforce. Engage and motivate your employees to understand how to save energy from the start. Consider engagement incentives.

5. Understand Your Energy Consumption
Understand where and why you consume energy.

6. Brainstorm
Review what you can change within the company‘s operation to reduce energy consumption.

7. Identify Indicators
Identify indicators that everyone can use to improve energy performance. (Energy Performance Indicators; EnPI’s)

8. Continually Learn
Accept that you might not get it right from the start. ISO 50001 is a continual learning process.

9. Seek an Expert if Required
Don’t hesitate to seek external consultative support on energy efficiency if you need help.
