ESOS (Energy Savings Opportunity Scheme)

ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. The Environment Agency is the UK scheme administrator.

Organisations that qualify for ESOS must carry out ESOS assessments every 4 years. These assessments are audits of the energy used by their buildings, industrial processes and transport to identify cost-effective energy saving measures.

Organisations must notify the Environment Agency by a set deadline that they have complied with their ESOS obligations. The deadline for the first compliance period, 5 December 2015, has now passed.

How the Scheme Works:

The ESOS Assessment requires participants to do 3 things

  1. Measure Total energy consumption
  2. Conduct energy audits to identify cost-effective energy efficiency recommendations
  3. Report compliance to the Environment Agency

ESOS will operate in four-yearly compliance phases. Organisations in the UK must assess whether or not they are required to participate in ESOS on the qualification date of each phase. The qualification date for the first phase is 31 December 2014
