Energy Audit Scheme

Is your business a LARGE Enterprise? Do you employ 250 employees or over (on payroll) or do you have an annual turnover in excess of €50m and an annual balance sheet total in excess of €43m. If you answered yes to either question, then this scheme may apply to your business.

In order for the EU to meet its binding energy efficiency and emissions targets, measures have been identfied that are required to be introduced by member states. The measures cover activities in the public sector, utilities, buildings and transport, financing of energy projects, and energy use in large enterprises.

Large Enterprises must carry out an energy audit of their operations every four years. The first such audit must be completed by 5th December 2015. 

The directive has been transposed into Irish Law as Statutory Instrument (SI) 426 of 2014. Part 3 of this legislation covers Energy Audits. 

How to comply

  1. Large Enterprises must either carry out an energy audit or
  2. Demonstrate that they are implementing an energy or environmental management system*.

*This must be certified by an independent body according to the relevant European or International standards. They must then be able to demonstrate to SEAI that the management system concerned includes a specific and detailed energy audit element.

In Ireland, this is referred to as the “Energy Auditing Scheme”. This audit must be completed every four years.

To demonstrate compliance, a business must use a Registered Energy Auditor to complete the audit.


Energy Audit handbook


New Energy Audit Handbook

SEAI has launched an Energy Audit Handbook. The handbook sets out the complete energy audit process guiding users each step of the way - from audit preparation and pre-analysis through to conducting the site visit and reporting findings. It gives the user a better understanding of what to expect from an energy auditor which can be particularly useful for companies preparing for their first audit. The handbook includes some key resources and a range of references offering a best practice framework for both high level and technically detailed use.
