ISO 50001

Take Control of Commercial Energy Costs
Have a System

Whether it’s an internationally recognised management system such as ISO 50001 or some other standard, the importance of having a systematic approach to managing energy costs is difficult to overstate.

Targets & Objectives

Setting targets and objectives and implementing a systematic monitoring and reporting regime empowers businesses to objectively measure improvements in energy performance.


Exciting new technologies such as CHP, Intelligent LED lighting, Thermal Storage, Solar PV, Smart Metering, Solar Thermal, Biomass, Inverter Drives, Aquifer Energy Storage and others are important tools to exploit to get energy costs under control.

Everyone is Involved

50001 Energy Management System requires all people in an organisation to be actively engaged. Only by getting everyone involved will enable a culture to develop that delivers continuous improvement in energy performance.

Energy Savings Opportunity Scheme



Who has to comply with ESOS?
Large organisations with more than 250 employees or a turnover in excess of €50M will be required to review total energy use from their buildings, transport and industrial processes.
Who benefits from ESOS?
It isn’t all bad news! The principal beneficiaries will be the organisations who embrace and implement the energy saving initiatives that are recommended in the audits. Reduced energy costs translate directly into increased profits.
What is an ESOS Assessment?
If your organisation falls under the scope of ESOS, you will need to engage with an accredited ESOS Lead Assessor. The Lead Assessor will audit your total energy consumption, identify cost-effective energy efficiency recommendations and then notify compliance to the Environment Agency.
Qualifying organisations will be required by law to notify compliance to the Environment Agency by no later than 5th December 2019, and then 4-yearly intervals from that point onwards. Embracing International Standards ISO 50001 is an internationally recognised standard for energy efficiency best practice and is an accepted route towards ESOS compliance. Epsilon are accredited to help organisations implement the 50001 standard and can ensure not just compliance with ESOS, but also recommend longer-term energy efficiency strategies designed to impact positively on your bottom line profitability.
Penalties for non-compliance?
The penalties for non-conforming range from fixed penalties of £5,000 up to £50,000, plus ongoing penalties for failure to resolve non-compliance.
Why are the penalties so severe?
The UK has legally binding emission reduction targets so need to ensure that major organisations introduce a program of regular energy audits to comply with Article 8 of the EU Energy Efficiency Directive.



The Audit Procedure

Our auditors are selected to meet the requirements of your particular sector. Your company’s activity, location of premises, size and complexity are all taken into account. On receipt of your application form, we will contact you to agree dates for the following:

A Document Review
The document review aims to establish that your quality documentation meets the requirements of the standard. We compile a detailed report and a planned audit schedule. These are discussed with you and provided for your information if deemed necessary by us or requested by the company, this can take place at your premises. This enables you to establish a rapport with your auditor and may help the incidence of non-conformances at the next stage.

The Audit

A detailed, on-site audit of your company’s documented system against the company’s working practices and the ISO standard. Findings of the audit are documented. If there are any areas of concern to the auditors, the following may be raised:

  • Major non-conformance – which must be rectified before certification can be recommended by the lead auditor.
  • Minor non-conformances – which do not affect the recommendation for approval but must be addressed prior to the issue of your certificate.
At the close of the audit, the Lead Auditor will leave his or her recommendation with you.


    Certification is valid for a three-year period and monitored by a registered auditor at regular intervals. All visits to your company are by appointment, thereby ensuring availability of relevant personnel. At the end of three years your organisation will need to be re-assessed. Fees for this will be kept to a minimum and discussed with you in advance.

    Please note: All audits are performed on the basis of sampling. If discrepancies are not discovered, there is no guarantee that they do not exist.

    Extension to Scope of Certificate

    Amendments or extensions to the initial certified scope are possible, for example, to include additional offices or new areas of business. Audits for this ‘extension’ can be carried out with minimum disruption to your organisation, often by allocating extra time around the time of a routine surveillance visit. Please let us know about any changes by contacting us by telephone, email or a letter.

    Rules For Appeal

    In the event of an audit which results in a recommendation to defer registration to the relevant standard (or at a later stage if notified that a certificate is to be withdrawn), a written appeal may be sent to Epsilon Consultants (IOM) Limited.

    All appeals will be heard by an Appeals Panel selected from the Governing Board. Your company has a right to object to any member forming part of the chosen panel. The Governing Board will then select a different panel. If the appeal is upheld, the findings of the auditor will be overruled. If the auditor is found to be correct, your company will be required to pay for a partial or full re-audit and the cost of the appeal. Such appeals are exceptionally rare.
