The typical process for ESOS is as follows:  

  • Allocate Lead Assessor to the project 
  • Evaluate energy consumption and determine what audits are required 
  • Complete the necessary audits  
  • Compile energy consumption covering a 12 month period that includes the qualification date of 31st December 2022 and summarise the audit reports and energy data to the client 
  • Finalise report, obtain board level signoff and register relevant consumption data and report findings with the Environment Agency to ensure Phase 3 compliance before the deadline of 5th December 2023
