Does the Energy Savings Opportunity Scheme apply to your organisation?

05 September 2014

Find out if your organisation qualifies as a ‘large enterprise’.

Esos (1)

There is new energy efficiency legislation in place for those organisations deemed to be ‘large enterprises’.  The repercussions on these businesses are going to be significant!  Do you work in a ‘large enterprise’?  You do if your organisation matches any of the following criteria:

  • Does your company have 250 or more employees in the UK?; OR
  • Does your company have fewer than 250 employees but an annual turnover exceeding €50m and a balance sheet exceeding €43m?; OR
  • Is your company part of a corporate group containing at least one ‘large undertaking’?

If you can answer yes to any ONE of the above criteria then, the Energy Savings Opportunity Scheme (ESOS) applies to you.  ESOS is a mandatory energy assessment and energy saving identification scheme for large undertakings and their corporate groups.  It is regulated by the EU Energy Efficiency Directive and applies across the UK.

What must you do if ESOS applies to you?

First of all, don’t panic!  Your organisation most likely has some elements required by ESOS in place.  These requirements are:

  • Measure your total energy consumption;
  • Conduct energy audits to identify cost-effective energy efficiency recommendations;
  • Report compliance to the Environment Agency.

Top tip

If you're certified to the ISO50001 Energy Management System there's no need to carry out ESOS audits. So certification is an excellent opportunity to satisfy your legal obligations whilst letting your stakeholders know that your company has a progressive approach to doing business.


It's estimated that a net value of £1.6 billion will be generated from the scheme in the UK and a majority of this money will apply directly to businesses through cost savings.


You must assess whether or not you're required to participate in ESOS by the 31st December 2014.

Bring on the energy savings!
