‘ISO 50001 is for large factories.’ And other myths that cost companies money.

Preconceptions can be more expensive than electricity bills. We’ve compiled the 6 most common myths about ISO 50001 – and we’re setting them against the facts.

Myth 1: “It’s a standard for large industrial plants; it doesn’t apply to us.”

This is the most common reason why companies don’t even start discussing ISO 50001.

Where does this myth come from? Probably from the fact that the standard is often associated with heavy industry – steelworks, cement plants, refineries. Indeed, in those sectors, savings are counted in millions and every percentage point of efficiency matters enormously. But the standard does not specify a minimum energy consumption or a minimum company size.

What is the reality? ISO 50001 can be implemented in a company employing 30 people, in an office building, a logistics centre, a food processing plant or a printing works. The key question is not “are we big enough?”, but “is energy a significant cost for us?” – and for most manufacturing, service or retail companies, the answer is yes.

Myth 2: “We’ve already had an energy audit; that’s enough.”

An energy audit and ISO 50001 are two completely different things – although many companies treat them as interchangeable.

An audit is like a snapshot: it shows energy consumption at a given moment, identifies areas of waste and suggests actions. A good audit has real value. But once the audit is complete, the report ends up on a desk and… that’s often where it ends. The regulations do not require the implementation of recommendations or the monitoring of results.

What is the reality? ISO 50001 is a film, not a snapshot. The system operates all year round, requiring regular monitoring, setting targets and checking whether they have been achieved. What is more, the Energy Efficiency Act allows companies holding ISO 50001 to use it to replace the mandatory audit – this is no coincidence. The legislator has recognised that an energy management system offers more guarantees of continuous operation than a one-off audit.

Myth 3: “Implementation is very expensive and complicated.”

This myth has two aspects: the belief that it is costly and the belief that it involves bureaucratic complexity.

What is the reality? The cost of implementation depends on the size of the organisation and its starting point. Companies that have already implemented other management systems (e.g. ISO 9001 or ISO 14001) benefit from a common structure – the so-called High Level Structure. Documentation, management reviews, internal audits, policies – a large proportion of these elements already exist or require only minor expansion. Implementation ‘from scratch’ in a medium-sized manufacturing company usually takes between a few and a dozen or so months and, with professional support, does not require the creation of a dedicated energy department.

As for bureaucracy – the standard does not impose specific document formats or a set number of procedures. It requires effectiveness, not paperwork.

Myth 4: “We get the certificate once and we’re set for years to come.”

The mindset: we implement, we get certified, and that’s the end of it.

What’s the reality? ISO 50001 certification requires annual surveillance audits and recertification every three years. This isn’t a drawback – it’s a mechanism that keeps the system alive. Organisations that treat ISO 50001 as a living system achieve sustainable, growing savings. Those that merely “pass the audit” lose momentum just a few months after certification.

The true value of the standard lies not in the certificate, but in what the company does between audits.

Myth 5: “It’s just a technical matter – all you need to do is hire an electrician or an energy engineer.”

Energy management is often confused with facilities management. These are two different areas of expertise.

What is the reality? ISO 50001 is a management system – and that means it involves senior management (who set the policy and objectives), the procurement department (which considers energy consumption when selecting equipment), the production department (which manages schedules and processes), and those responsible for monitoring data. An energy manager or facility manager is an important participant, but cannot be the only one.

Companies that attempt to implement ISO 50001 ‘through a single person’ usually end up with a system that exists on paper but does not change the day-to-day running of the organisation.

Myth 6: “If there are no penalties for not having a certificate, why bother getting one?”

It is true that there are no direct penalties for not having a certificate. But the question “what for?” is being answered more and more often.

What is the reality? Market pressure is growing faster than regulatory pressure. Large companies in the automotive, FMCG, retail and energy sectors are increasingly requiring suppliers to document their efforts towards energy efficiency and carbon footprint reduction. ISO 50001 is becoming part of supplier assessment – not a “nice-to-have” certificate, but a prerequisite for participation in the supply chain.

Added to this are ESG reporting requirements, which are covering an ever-wider range of companies. Organisations that start managing their energy today will have the data and documented results ready when regulations require them. Those that wait will be left scrambling to catch up.

Summary: Myth versus reality

Beliefs about ISO 50001 often stem from a lack of practical experience with its implementation. The standard is not intended solely for large facilities; it is not a one-off project; it does not require an army of specialists; and it is not purely a technical matter.

It is a business decision: do we want to know what is really happening with our energy costs – and do we want to have a say in it?
