Energy Savings Opportunity Scheme (ESOS)

The Energy Savings Opportunity Scheme (ESOS) applies to all UK organisations who meet the ESOS qualification criteria.

Qualifying organisations are required to undertake ESOS audits in order to review their energy consumption and improve efficiency. Every four years, organisations must carry out energy audits for notification to the Environment Agency.

ESOS Energy Audits will consider:

  • Energy usage
  • Buildings
  • Processes (e.g. industrial, chemical, manufacturing, food, etc.)
  • Transport

Although ESOS is a mandatory requirement, the scheme can also be used to improve profitability and competitiveness by implementing lucrative energy efficiency improvements.

ESOS Compliance Phase 2 – 5 December 2019

Phase 2 of the ESOS compliance scheme has already begun.

Organisations now need to start undertaking ESOS audits to identify energy saving opportunities for their business. Audits can now take place to enable organisations to collect the required 12 months’ verifiable data to include the qualification date of 31 December 2018.

Organisations which qualify for ESOS need to:

  • Calculate total energy consumption
  • Identify energy efficiency improvements
  • Appoint a Lead Assessor
  • Notify compliance to the Environment Agency by 5 December 2019
  • Keep records and maintain an ESOS evidence pack
