Improving business performance through energy efficiency
Companies who fall within the scope of ESOS are required to undertake an energy audit conducted or overseen by an approved ESOS Lead Assessor unless the organisation is fully covered by ISO 50001. Audits must be conducted every four years. The first deadline was 5 December 2015, the second was 5 December 2019 and the next deadline will be 5 December 2023.
The EI runs one of the biggest registers of qualified ESOS lead assessors – experienced professionals to help your business get the most out of its energy spend, providing advice you can trust.
What is ESOS
ESOS is the UK’s response to Article 8 of the European Commission’s Energy Efficiency Directive. It aims to cut carbon emissions by requiring the thousands of large businesses that operate in the UK to measure their energy consumption and identify measures that could be implemented to achieve energy savings.Read more »
