Energy Saving Opportunity Scheme (ESOS) Scheme

About the ESOS Scheme…

ESOS Energy SchemeThe (ESOS) Energy Savings Opportunity Scheme is a mandatory requirement for all large enterprises in the UK. The scheme requires recording and reporting of energy data for buildings, transport, and industrial processes over a 12-month period. Additionally, depending on the size and complexity of your portfolio of buildings, the scheme requires energy surveys accompanied by cost-effective recommendations to reduce energy demand and improve energy efficiency. As the name implies, the focus is on opportunities to reduce energy use and its associated cost to UK plc.
