Energy Saving Opportunity Scheme (ESOS)

The Energy Savings Opportunity Scheme Regulations 2014 (ESOS Regulations) came into force in 2014 and Phase One of the scheme required all qualifying organisations to notify compliance by 5th December 2015. Phase Two of the scheme is now live and requires all qualifying organisations to notify compliance by 5th December 2019.

All organisations meeting the qualification threshold are legally required to participate. The threshold is 250 or more employees or if you have fewer employees then the threshold is turnover in excess of £44,845,000 and balance sheet total assets in excess of £38,566,700. This is for the organisation's financial year that includes the qualification date of 31st December 2018.

We have extensive experience of collecting the data and preparing ESOS Audit Reports on behalf of clients. Our Lead Assessor, Martyn Green, is Elmhurst Energy Systems qualified and is on their register with the Environment Agency. We also have experience of successfully supporting and guiding clients through Environment Agency Audits.

Xcarbon specialises in ESOS. If you would like to discuss ESOS compliance and reporting or how your organisation can best reduce its compliance costs, then please call us on +44 (0) 845 475 2102.

Xcarbon is providing a full ESOS service for a number of participating organisations. We can also address specific issues such as:

  • Evaluating qualification for Phase 2 of ESOS
  • Developing an ESOS strategy in partnership with your organisation
  • Data collection and collation, including grey fleet
  • Carrying out site energy audits
  • Calculating Total Energy Consumption (TEC)
  • Energy profiling
  • Identifying, evaluating and prioritising energy efficiency projects
  • Preparing and presenting the ESOS Report
  • Compliance with Environment Agency notification procedures

The ESOS regulations impose heavy penalties for organisations who fail to comply or are late reporting, so it can make sense to outsource some or all aspects of the ESOS process to specialists.
