    • Energy-intensive operations: manufacturing, data centres, logistics
    • Public sector and ESOS-affected UK organisations
    • Anyone with serious net-zero or cost-reduction targets

    What you'll gain

    • Lower energy bills through systematic improvement
    • Support ESOS and net-zero reporting obligations

    Deep dive

    A closer look at ISO 50001

    ISO 50001 is the international standard for energy management systems. It helps organisations understand how they use energy, identify opportunities to improve energy performance, reduce waste, control energy-related risks and support carbon and cost reduction goals.

    Our AI-supported remote audit for ISO 50001 helps you review your energy management system in a clear and practical way. The platform guides you through the requirements, explains what evidence is needed, and helps you demonstrate how energy performance is planned, measured, reviewed and improved.

    Latest standard position

    ISO 50001:2018 remains current and was confirmed by ISO in 2024. It also has ISO 50001:2018/Amd 1:2024, the climate action amendment, which ISO lists as published and applicable to ISO 50001:2018. (ISO)

    Our platform supports ISO 50001:2018 and includes the 2024 climate action amendment considerations as part of context and planning.

    What ISO 50001 helps you prove

    ISO 50001 helps you show that energy is being managed systematically. It expects you to understand how energy is used, identify significant energy uses, establish energy baselines and performance indicators, set objectives and action plans, monitor performance and continually improve.

    In simple terms, it helps you answer these questions. Where do we use the most energy? What affects our energy use? How do we measure improvement? What actions are we taking? Are savings being achieved? Are energy decisions built into purchasing, design, maintenance and operations?

    How the AI-supported remote audit works

    The platform asks clear, clause-based questions and guides you to upload relevant evidence. This may include energy data, metering records, bills, energy reviews, objectives, action plans, operational controls, maintenance records and management review minutes.

    The AI review checks whether the evidence appears to demonstrate conformance and identifies where information may be missing or unclear.

    Key areas reviewed

    Organisational context

    We review whether your organisation understands the internal and external issues that affect energy performance. This may include energy prices, operational demands, site conditions, equipment age, production patterns, carbon targets, customer expectations and legal requirements.

    Typical evidence may include a context review, interested parties register, energy strategy, utility information, compliance register, business plan and management review minutes.

    Energy management system scope

    We check whether the scope of the energy management system is clear. This should define the sites, activities, facilities, equipment and energy types included.

    Typical evidence may include the EnMS scope statement, site list, process map, energy flow diagram, utility meters, organisational chart and operational descriptions.

    Leadership and energy policy

    We review whether top management supports energy management and whether the energy policy is appropriate to the organisation's activities and energy use.

    Typical evidence may include the energy policy, leadership meeting minutes, energy responsibilities, objectives, budget approvals, communication records and management review outputs.

    Energy review

    The energy review is one of the most important parts of ISO 50001. We check whether the organisation has analysed energy use and consumption, identified significant energy uses and considered variables that affect energy performance.

    Typical evidence may include energy bills, meter readings, half-hourly data, equipment lists, energy use breakdowns, production data, occupancy data, weather data, operating hours and significant energy use analysis.

    Energy baseline and energy performance indicators

    We review whether energy baselines and energy performance indicators have been established and are appropriate for measuring improvement.

    Typical evidence may include baseline calculations, EnPIs, energy consumption trends, normalisation methods, relevant variables, calculation methods, review records and performance dashboards.

    Legal and other requirements

    We check whether applicable energy-related legal and other requirements have been identified and evaluated.

    Typical evidence may include a legal register, ESOS information where relevant, SECR information where relevant, customer requirements, landlord requirements, compliance evaluations and management review records.

    Objectives, targets and action plans

    We review whether energy objectives are measurable, realistic and linked to opportunities for improving energy performance.

    Typical evidence may include energy objectives, action plans, project plans, responsible persons, target dates, budgets, expected savings, actual savings and progress reviews.

    Operational control

    We check how energy use is controlled in day-to-day operations. This may include plant operation, heating, cooling, lighting, compressed air, vehicle fuel, maintenance, shutdown routines and employee behaviour.

    Typical evidence may include operating procedures, maintenance schedules, building management system records, equipment settings, shutdown checklists, inspection records, training records and energy awareness communications.

    Design and procurement

    ISO 50001 expects energy performance to be considered when designing new or modified facilities, equipment, systems and processes, and when procuring energy-using products or services.

    Typical evidence may include procurement specifications, tender criteria, equipment selection records, lifecycle costing, design reviews, supplier information, energy efficiency assessments and commissioning records.

    Monitoring, measurement and analysis

    We review whether energy performance is measured, analysed and reviewed.

    Typical evidence may include meter readings, energy dashboards, utility invoices, sub-metering records, exception reports, variance analysis, calibration records where relevant and performance reports.

    Internal audit and management review

    We check whether the energy management system is audited and reviewed by management.

    Typical evidence may include internal audit programme, internal audit reports, nonconformity records, management review minutes, energy performance updates, compliance evaluations and improvement actions.

    Improvement

    We review whether the organisation takes action when energy performance does not meet expectations and whether improvement opportunities are acted upon.

    Typical evidence may include corrective actions, energy project reviews, lessons learned, improvement logs, maintenance actions and updated objectives.

    What you receive from the platform

    The platform provides a clear audit output showing where your energy management system appears to meet ISO 50001, where further evidence may be needed, and where improvement opportunities or potential nonconformities may exist.

    This can support certification preparation, energy performance improvement, internal audit, carbon reduction planning and management review.

    Plain-English summary

    ISO 50001 helps you prove that energy is being actively managed, not simply paid for. Our AI-supported remote audit helps you understand your energy evidence, identify gaps and support measurable improvement.
