Environmental guidance for your business in Northern Ireland & Scotland

Energy Saving Opportunities Scheme (ESOS)

Are you affected by the ESOS regulations?

Your will have to comply with the requirements of the ESOS regulations if:

  • Your organisation employs more than 250 people
  • You employ less than 250 people, but have a turnover greater than 50 million Euros or your balance sheet is greater than 43 million Euros.

You are affected if your organisation meets these requirements on 31 December 2014 or in the 12 months before 31 December 2014.

The ESOS regulations apply mainly to businesses, but will apply to any non-profit or other non-public sector organisation that meets the criteria.

Who administers the ESOS regulations?

The Environment Agency (EA) administers the scheme for the whole of the UK.

What do I need to do?

If you are affected by the ESOS regulations then you must:

  • Calculate total energy consumption. This includes energy used in buildings, processes and transport by your organisation or group.
  • Identify areas of significant consumption. This must account for 90% of total energy used by your organisation.
  • Appoint a lead assessor. Your lead assessor with carry out or oversee your energy audits or overall ESOS assessment.
  • Notify the Environment Agency. By 5 December 2015 you must submit your ESOS notification of compliance to the EA.
  • Keep records. You must keep records of how you have complied with the ESOS regulations.
