The Energy Saving Opportunity Scheme (ESOS) is a mandatory assessment scheme for qualifying customers, introduced by Department of Energy and Climate Change (DECC). The deadline to complete an energy audit and identify energy saving opportunities across your business was 29 January 2016.

According to the Department of Energy and Climate Change (DECC), by improving energy efficiency and energy management a business can reduce its annual energy costs by 20% on average.
