Energy Saving Opportunities Scheme (ESOS)

The Energy Saving Opportunity Scheme (ESOS) came into force in July 2014. The scheme requires large companies to conduct a full energy audit by the end of 2015 and then repeat that audit every four years. At the end of the assessment, potential energy-saving opportunities will be identified. The cost of these opportunities should be based on an analysis of whether the investment will be economical over its entire life. 
 
As a minimum, large organisations will be required to review total energy use from their business operations, including building energy use, transport energy use and industrial processes. Organisations are also required to calculate the amount of energy used per employee.
 
ESOS offers the following advice for lighting: 
 
“Install occupancy sensors, install daylight sensors, review and improve the maintenance plan (more regular maintenance), replace inefficient incandescent bulbs with high efficiency LED lighting.”

Here are some key points: 
 
  • Definition of a large company is defined by companies with 250 or more employees or companies with a turnover greater than €50 million (around £40 million)
  • Around 9000 organisations in the UK will qualify. This includes not-for-profit organisations
  • Most public sector bodies are excluded, but some, such as many Universities may qualify
  • A full energy audit must be completed by 2015 and then repeated every four years
  • Initial audits must be undertaken by 5th December 2015
