What can you do now to begin your ESOS Phase 2 compliance?


  • Choose an ESOS Lead Assessor from the register of lead assessors 
  • Carry out an ESOS energy assessment of your buildings, processes and transport 
  • Gather the energy data for your twelve months’ reference period, which overlaps the reference date of 31st December 2018
  • If you have an Environmental Management System (EMS) or an Energy Management System (EnMS) you can efficiently streamline your ESOS obligations within your ISO 14001 EMS and/or utilitise your EnMS certified to 50001 using the same energy audits and energy data for both – or all three – reporting platforms.
