There’s still time to implement ISO 50001 before this deadline
In their July 2021 consultation paper, titled Strengthening the Energy Savings Opportunity Scheme (ESOS), BEIS recapped that:
There are currently three alternative routes to complying with ESOS, other than an energy audit signed off by an ESOS lead assessor: ISO 50001, Display Energy Certificates (DECs) and Green Deal Assessments (GDAs)
They concluded that:
ISO 50001 is generally considered to be a good compliance route that requires organisations to take responsibility for their own energy management and set targets for reduction. We propose to include more information in ESOS guidance on the benefits of compliance via this route and encourage participants to comply using this route
ISO 50001:2018 is a globally recognised ISO standard that provides a structured approach for organisations to create an effective Energy Management System (EnMS). The system provides good practice guidelines on gathering accurate energy usage data and developing a plan to improve operational efficiency. The standard is based on the Plan-Do-Check-Act continual improvement model which enables an organisation to continually evaluate the success of its energy consumption plan and keep improving it. ISO 50001 provides a framework of requirements for organisations to:

Energy consumption is rapidly increasing internationally so improving energy efficiency and climate change challenges make up a key part of the 17 Sustainable Development Goals in the United Nations 2030 Agenda. ISO 50001 helps organise processes and procedures that can contribute to the achievement of goals 7 and 13.

Whether your focus is on demonstrating compliance with ESOS or a broader strategic objective to contribute to the Sustainable Development Goals (SDGs), looking at ISO 50001 and other core ISO standards may be the best approach for you.
