The ESOS assessment is an energy audit of an organisation’s total energy consumption across buildings, transport and industrial activities. The assessment is carried out every four years.
Organisations that are expected to fulfil the requirements of the legislation are those with 250 employees or more, or an annual turnover in excess of £38,937,777 (and an annual balance sheet total in excess of £33,486,489). A business must initially notify the Environment Agency that it has a requirement to undertake audit. The qualification date, i.e. the deadline for notifying the Environment Agency, is 31 December 2014.
The Environment Agency will hold and maintain the register of ESOS Assessments and the deadline for submitting the first assessment is 5 December 2015.
12 months of recent energy data is required as part of the energy audit. Energy used by the business will be assessed under three categories; building, transport and process. The organisation will be required to appoint a Lead Energy Assessor to undertake, oversee or review the energy audits and the ESOS Assessment overall. As part of the assessment, energy saving opportunities will be identified by the Lead Assessor.
A Lead Assessor must be a member of an approved professional body, registered with the Environment Agency.
