Energy Savings Oportunity Scheme (ESOS) involves an energy assessment, identifying opportunities for energy savings – it’s mandatory for large organisations in the UK.

Do I need an ESOS assessment?

You qualify if your organisation employs at least 250 people or has an annual turnover of more than £39 million and an annual balance sheet exceeding £33.5 million. After the first phase was completed in December 2015, the deadline for ESOS Phase 2 is December 2019.

What does ESOS involve?

Qualifying organisations need to measure their annual total energy consumption (including buildings, transport and industrial activities) and carry out energy audits to identify energy efficiency opportunities. If you qualify, you should engage ESOS assessors and begin the assessment process soon to avoid the risk of delays and penalty charges.
