Additional ESOS guidance

Introduced in 2015, the Energy Savings Opportunity Scheme (ESOS) requires obligated UK organisations to complete an energy audit to identify potential opportunities for better energy efficiency.

In addition to explaining what you need to do to comply, we have compiled these frequently asked questions to guide you on your way.


Your ESOS compliance questions answered


Over what period does this apply?

The ESOS assessment must cover all UK operations over a 12-month period, which must take in the 31 December 2014 and end before 31 December 2015. That means your reporting period can cover any time from 31 December 2013.


Are there any exemptions?

Yes, there are. If you are already ISO50001 accredited for your full UK operation, it’s clear you’re well on the way to good energy performance management and the Environment Agency considers you to be ESOS compliant already. You will, however, need  to notify the EA regardless.

Some exemptions also apply with Green Deal Assessments (GDAs) and Display Energy Certificates (DECs) but you need to check.


What happens if I don’t comply with ESOS legislation when I’m obligated?

As you might expect, non-compliance of any organisation or group who is required to participate in ESOS carries civil penalties. This is stated to include:

  • Public disclosure of non-compliant organisations and details non-compliance otherwise known as ‘naming and shaming to the media
  • Financial penalties range between £5,000 and £50,000 plus £500 per day thereafter (up to 80 days)

In short, there are significant risks to your organisation that could easily be avoided.


How often do we need to go through this process?

Once you have demonstrated ESOS compliance, you won’t need to undertake another energy audit for four years. This is in line with the Energy Efficiency Directive, issued by the EU.

However, given the opportunity to reduce overheads and your carbon footprint, you might want to adopt a more rigorous strategy and look to gain ISO50001 accreditation. This is something we can help with so do contact the Ecosurety team for more information.


When will I need to get started?

The absolute deadline for reporting your ESOS compliance was the 29 January 2016. Even though this has passed, we would recommend getting it underway as soon as possible as we are anticipating the EA to bring enforcement action against any company that is out of ESOS compliance. You can start the process at any time, but the sooner the better.


How long will the ESOS compliance audit take?

Inevitably this will depend on the complexity of your organisation, taking in how many sites you have and your transport infrastructure. We can reduce some of the duplication in the auditing process as it’s possible to take a sample of one site if it is sufficiently similar to another. This would be determined in the process.

We would recommend allowing 8 to 12 weeks for the full process to be completed from start to finish, including planning, implementation, reporting and submission.


How much does this process normally cost?

Again, this will vary depending on the complexity of your organisation and therefore the number of person hours required to complete the process. 


We hope this has answered most of your burning questions on ESOS; if not, please don’t hesitate to drop our ESOS specialist team a line and we’ll do our best to help.
