Readiness check
ISO 50001 checklist for your energy management system
This checklist follows the clauses of ISO 50001:2018 and names the evidence you typically already hold for each point. If you can tick most of it, you are ready for the self-assessment. The gaps show you what to fix first.
01: Overview
What an ISO 50001 checklist has to cover
ISO 50001:2018 uses the same clause structure as ISO 9001 and ISO 14001. Clauses 1 to 3 cover scope, references and terms and contain no requirements. The requirements sit in clauses 4 to 10, so the checklist below has seven blocks.
Evidence means documents and records, not good intentions. A signed energy policy, a list of meters, a spreadsheet with monthly consumption and a maintenance schedule are all valid. Most small and medium businesses already hold the raw material in their energy invoices and meter readings. It only has to be organised.
| Clause | Question you must answer | Typical evidence |
|---|---|---|
| 4 Context | Which sites, energy types and parties are in scope? | Scope statement, site list, register of requirements |
| 5 Leadership | Has management committed and named someone responsible? | Signed energy policy, appointment of the energy lead |
| 6 Planning | Where does the energy go and what do you want to change? | Energy review, baseline, EnPIs, action plan |
| 7 Support | Do people have the means and the knowledge? | Training records, controlled documents |
| 8 Operation | Are the big consumers run and bought with efficiency in mind? | Maintenance plans, setpoint lists, purchasing criteria |
| 9 Performance evaluation | Do you measure, audit and review? | Meter readings, internal audit report, review minutes |
| 10 Improvement | What do you do when something goes wrong? | Corrective action log, updated action plan |
02: Clauses 4 and 5
Checklist for context and leadership
These points are quick to settle, but they set the boundaries for everything that follows. Do them first.
Define the scope of the energy management system
State which sites, buildings, processes and energy types are included. Evidence: a one-page scope statement with the list of sites.
List the interested parties and what they expect
Think of the energy supplier, the landlord, customers who send supplier questionnaires and the authorities. Evidence: a short register with the requirement and the owner of each entry.
Issue an energy policy
Top management signs it. It commits to improving energy performance and to buying energy-efficient products and services. Evidence: the signed policy and proof that staff have seen it, for example a notice or an intranet page.
Appoint an energy lead and a small team
Responsibilities and authority must be written down. Evidence: an organisation chart or a letter of appointment, plus the first meeting minutes.
03: Clause 6
Checklist for planning: baseline, significant uses and EnPIs
Clause 6 carries most of the substance of ISO 50001. A reviewer wants to see numbers, not statements.
Record risks and opportunities
Examples are rising energy prices, ageing equipment or a planned extension. Evidence: a short list with an action or a decision against each item.
Carry out an energy review
Analyse past consumption by energy type: electricity, gas, heating oil, fuel. Evidence: invoices and meter readings for a continuous period, summarised in a spreadsheet.
Identify significant energy uses
Rank the consumers by share of total energy: compressors, process heat, cooling, lighting, the vehicle fleet. Evidence: a ranked list that shows why each use is called significant.
Establish the energy baseline
Fix a reference period and note the variables that affect consumption, such as production volume or heating degree days. Evidence: the baseline sheet with the period and the variables.
Define energy performance indicators
Choose figures such as kWh per unit produced or kWh per square metre. Evidence: a monthly tracking table that compares each indicator with the baseline.
Set objectives and action plans
Each objective needs an owner, a deadline and the resources assigned. Evidence: a written action plan, for example replacing a compressor or adjusting heating setpoints.
04: Clauses 7 and 8
Checklist for support and operation
Here the standard asks whether the plan reaches the people who run the machines and buy the equipment.
Provide resources and check competence
Those who operate or maintain significant energy uses know what influences consumption. Evidence: training records and job descriptions.
Make staff aware
People understand the policy and how their work affects energy use. Evidence: toolbox talk notes, notices at the machines, onboarding material.
Control your documented information
Policy, baseline, action plan and records are current and easy to find. Evidence: one folder or system with version dates.
Control operation of significant uses
Set criteria for running and maintaining the big consumers. Evidence: maintenance schedule, setpoint lists, shift instructions.
Consider energy performance when you buy
Equipment, energy and services are compared on consumption as well as price. Evidence: purchasing criteria and quotes that show expected consumption.
05: Clauses 9 and 10
Checklist for evaluation and improvement
The standard closes with the loop: measure, check, correct. A company that runs this loop once has usually done the hard part.
Monitor and measure
Meters or regular readings cover the significant uses and feed the indicators. Evidence: meter list, reading log, notes on how meters are checked.
Evaluate compliance
Check the legal and other requirements you listed under clause 4 at fixed intervals. Evidence: the register with review dates.
Run an internal audit
Someone checks the system against the standard and reports findings. Evidence: audit plan, checklist and report.
Hold a management review
Management looks at the indicators, the audit result and the action plan, then decides. Evidence: minutes with decisions and owners.
Handle nonconformities and keep improving
Problems are recorded, their cause is removed and the effect is checked. Evidence: a corrective action log and an updated action plan.
06: With Zertify
From checklist to certificate with Zertify
The Zertify self-assessment for ISO 50001 has 32 yes/no questions. 13 of them are mandatory requirements of the standard and must all be answered yes. Of the other 19, at least 13 need a yes. The checklist above covers the same ground, so working through it first makes the questions easy to answer.
After you pass and pay, the certificate arrives within 4 hours. There is no on-site audit. The certificate is issued by G6 Agency AG under licence from SICE, and SICE reviews every assessment before issue. Anyone can check it by number or QR code on the public verification page, which is useful when a purchasing department or a customer audit asks for proof.
The price is CHF 749 (€749) in the first year, then CHF 499 (€499) per year including the yearly online re-audit. The certificate is valid for 3 years.
