Phase 2 of the Energy Savings Opportunity Scheme (ESOS) makes it mandatory for large UK organisations to measure energy consumption and carry out energy audits. If you operate in the other EU Member States, you may need to comply with local ESOS-equivalents in those territories.
ESOS is the UK’s response to Article 8 of the EU Energy Efficiency Directive (EED). The ESOS regulation introduces mandatory requirements for large businesses within the UK, which must be carried out once every four years. The deadline for compliance with ESOS Phase 1 was 5th December 2015, whilst the deadline for Phase 2 is 5th December 2019.
