What is ESOS?
The UK Government introduced the Energy Savings Opportunity Scheme (ESOS) in response to the EU Energy Efficiency Directive (2012/27/EU). ESOS is a mandatory energy assessment scheme for organisations in the UK that meet the qualification criteria. Further information about the ESOS scheme can be found in the DECC Guide to ESOS (pdf). Companies that qualify need to appoint a Lead Assessor from an approved professional body register to undertake an energy audit and ESOS assessment.
