How to get ISO 50001 certified

Step 01

Gap assessment

We compare your current practices against every clause of ISO 50001:2018 and give you a prioritised list of what is missing.

Step 02

Leadership, policy & energy team

Top management commits to an energy policy, sets the scope and boundaries of the system, and appoints an energy management team.

Step 03

Energy review

We analyse your energy use and consumption, and identify your Significant Energy Uses (SEUs) and the variables that drive them.

Step 04

Baselines, EnPIs & targets

We set energy baselines (EnBs) and energy performance indicators (EnPIs), then agree objectives, targets and action plans.

Step 05

Implementation & documentation

Operational controls, procurement and design criteria, competence and awareness, metering, and the documented information the standard requires.

Step 06

Internal audit & management review

We run an internal audit, close the nonconformities it finds, and support top management through its first management review.

Step 07

Certification audit

An accredited certification body audits you in two stages: Stage 1 reviews documentation and readiness, Stage 2 verifies the system works in practice. The certificate is valid for three years, with annual surveillance audits.

Frequently asked questions

What is ISO 50001?
ISO 50001 is the international standard for energy management systems (EnMS), published by ISO. The current version is ISO 50001:2018. It sets out how an organisation plans, measures and continually improves its energy performance using a Plan–Do–Check–Act cycle.
How long does ISO 50001 certification take?
It depends on the size of the organisation, the number of sites and how mature your energy data is. Many organisations reach certification readiness in roughly 6 to 12 months. A gap assessment gives you a realistic timeline for your case.
Does Envera issue the ISO 50001 certificate?
No. Certificates are issued by independent, accredited certification bodies. Envera prepares you for the certification audit: we build and implement the energy management system with you, run the internal audit and support you during the external audit.
Who needs ISO 50001?
Any organisation that wants to control energy costs systematically. It is most common in energy-intensive sectors such as oil & gas, cement, steel, petrochemicals, textiles and large commercial real estate. Some customers, lenders and regulators also ask for it.
What is the difference between ISO 50001 and ISO 14001?
ISO 14001 covers environmental management in general; ISO 50001 focuses specifically on energy performance, with measurable requirements such as energy baselines and EnPIs. The two share the same high-level structure, so they integrate easily.
Does ISO 50001 actually reduce energy costs?
Yes, that is the point of the standard: it requires you to demonstrate continual improvement in energy performance, not just keep documents. We start with no-cost and low-cost measures that pay back quickly, and verify every saving against the baseline.
