What is ESOS

The energy savings opportunities scheme (ESOS) introduced by the Government in late 2014. This will require large companies to periodically (every 4 years) complete energy audits of a specific standard and content which cover most energy consumption within a company to help reduction in UK carbon emission. The overall energy assessments must be signed off by a suitably qualified and experienced Lead Assessor who is a registered by an approved professional body.

Qualified Companies

Companies need to comply with ESOS if at least one UK group member fall into one of the below categories:

  • Have more than 250 employees (including overseas companies with a UK registered establishment which are paying tax in the UK) OR
  • Have an annual turnover of more than €50m (£39m) & an annual balance sheet total of more than €43m (£33m).

To comply, companies must:

  • measure their total energy consumption;
  • conduct audits to identify cost-effective energy efficiency opportunities; and
  • report compliance to their national scheme administrator – the Environment Agency in England, SEPA in Scotland, NIEA in Northern Ireland and NRW in Wales

An alternative route to compliance with ESOS is for the company to develop and implement a formal energy management system which is accredited to the standard ISO 50001.
If your business qualifies for ESOS and the organisation is fully covered by ISO 50001, then ESOS assessment will not be needed to carry out, the organisation just need to notify the Environment Agency that you are compliant with ESOS.

Deadlines for ESOS compliance

The deadline for ESOS Phase 2 is 5th December 2019.

Qualifying organisations that do not complete and notify a compliance assessment by the above deadline are in breach of the regulation and at risk of enforcement action and penalties.

ESOS Support from Synergie Environ

Synergie Environ with their highly qualified team has expertise and extensive experience of helping companies to comply with ESOS. Our team can guide you through the compliance process from the very early stage to the final stage. Our support includes managing the data collection, analysis and report production required for ESOS compliance and we make sure your business will comply fully with all ESOS obligations.
The ESOS energy assessment will be reviewed and signed off by our highly qualified and experienced ESOS Lead Assessors or Lead ISO50001 Energy Management Systems Auditors as appropriate.
As part of our energy audits, we will identify suitable energy-saving measures and identify the potential cost and energy savings your business can achieve.
For the December 2015 deadline (Phase One) Synergie Environ audited more than 25 sites for ESOS assessment and identified opportunities to reduce energy by over 2,000 MWh per annum which is equivalent to energy cost savings of over £500k and over 2,500 tonnes in carbon dioxide emission per annum.



  • I thought Synergie Environ did an excellent job. The main point for me was turning the changes/savings into cash.

  • Babcock would like to commend Synergie Environ for thoroughness and the professional manner in which the project was carried out including the presentation of the findings and related recommended actions.

  • The report that was generated and delivered to us was not only comprehensive and accurate it also identified key areas that the site should actively pursue. This report was reviewed by the site and action plans have been developed from this.  Thank you one and all for your time, effort, inspiration, advice and encouragement over the past few months. The feedback you have given the team at times has really made a difference to their motivational levels. We will most likely be in touch again to ask for further advice or hopefully to share successes we have had.

    Alex Currie Spirits & CI Manager, Diageo plc
  •  Thank you for the time and effort you have obviously taken preparing the report and thank you for the professional and courteous manner in which you have dealt with our requirements and the way in which you conducted yourself while on site.

  •  Thanks again for your work - we are slowly working our way through it but it is going to be very valuable to us.

  • I appreciate the work that you've done, it both contributes to our work we're doing for strategy over the next two years, and also it adds some weight to the need for a dedicated energy manager...very useful!

  • Via Scottish Enterprise we were introduced to Synergie as part of their LCIP/LCITP programmes. The first piece of work we did with Synergie was to undertake a study of our current operations, the desired output being: i) a company specific energy and water master plan and strategy to reduce consumption, ii) recommendations on the design of our new manufacturing facility in terms of improving energy usage and efficiency, and iii) a benchmarking of our carbon emissions. From the outset, as demonstrated by their project scoping document, Synergie were thorough and detailed. This was consistent with the delivery of the project and the final report gave clear, justified recommendations. We particularly appreciated their ability to work within the constraints of our supply chain; being largely 3rd party, in some cases we weren’t able to provide data direct from those 3rd parties, however Synergie always had a workable workaround! Given the success of that project, and its viable recommendations, we decided to progress to the next phase which was to develop a detailed business case for the implementation of Trigeneration. We had 3 weeks to turn the project around, which required to-the-day planning and coordination, which Synergie were able to deliver whilst clearly demonstrating their ability to manage resources last minute to cope. Communication throughout was regular and reliable; Synergie delivered exactly what they said they would, exactly when they said they would.
