ESOS Phase 3: Key deadlines and the importance of ESOS Action Plan Progress Updates

The Environment Agency has announced that the portal for ESOS Action Plan Progress updates is now open, and organisations can submit their updates. For organisations qualifying for Phase 3 of ESOS, the deadline for submitting your ESOS Progress Update 1 is the 5 December 2025.

What is an Action Plan Progress Update?

Organisations that are required to comply with the Energy Savings Opportunity Scheme (ESOS), must also submit an Action Plan every four years to demonstrate the energy savings changes they plan to implement over the next ESOS Phase. In addition to this, a yearly progress update must be submitted to track the success of the energy saving projects set out in the Action Plan.

More than just compliance

Organisations that submit their progress updates annually, could benefit from more than just ticking a compliance box.

The progress update highlights the commitment of organisations to the goals outlined in their ESOS Action Plan, ensuring they are on track and transparent about their energy efficiency efforts. This can enhance an organisation’s reputation and demonstrate their commitment to sustainability.

Submitting the update can also provide a structured way to track and report on the implementation of energy saving actions. The update can help organisations monitor their own progress, identify barriers and adjust their strategy. By regularly reviewing their progress, organisations can ensure they are on track to achieve their energy efficiency targets.

Our Head of Operations, Timothy Holman, says

“Preparing and submitting a progress report can support businesses in their energy efficiency and carbon reduction initiatives. By keeping them on target, enabling them to provide measurable data and publicly disclosing the positive changes being made, organisation can benefit hugely from meeting this compliance obligation.”

Do I have to submit a progress update?

Organisations will not be fined for not submitting an update, however if an organisation does not submit anything at all or if they have not made any progress towards their energy saving goals, the Environment Agency will publish this information.

This public disclosure could impact organisations’ reputation, as they may be perceived by customers, employees and stakeholders as not taking sufficient action towards energy and carbon reduction.

By submitting your progress update on the online portal before the deadline of 5 December 2025, you can demonstrate the work that your organisation is doing to make energy and carbon savings.
