How EMMA AI Simplifies ESOS Compliance
ESOS is Changing: What You Need to Know
The Energy Savings Opportunity Scheme (ESOS) in the UK is undergoing significant changes in 2025 as it transitions into Phase 4. These modifications aim to make ESOS more effective in driving energy efficiency and aligning with the UK’s net zero commitments. If your business participates in ESOS, it’s critical to understand these updates and take action to prepare.

Key Changes to ESOS:
1. Introduction of Net Zero Assessments
2. Alignment with SECR Criteria
The scope thresholds for ESOS will now align with the Streamlined Energy and Carbon Reporting (SECR) framework. Businesses with at least 250 employees, an annual turnover of £36 million, or a balance sheet of £18 million will need to comply. This broadens the range of organisations required to participate in ESOS.
3. Mandatory Action on Audit Recommendations
From Phase 4 onwards, businesses must act on audit recommendations. If recommended actions are not implemented, organisations must provide a public explanation for their decision, increasing accountability and transparency.
4. Adherence to Recognised Auditing Standards
ESOS reports must now meet recognised auditing standards, such as ISO 50002 or EN 16247, to ensure consistency and accuracy in identifying and reporting energy-saving opportunities.
5. Removal of DECs and GDAs as Compliance Routes
Display Energy Certificates (DECs) and Green Deal Assessments (GDAs) will no longer be valid compliance routes, focusing ESOS on more robust and standardised evaluations.
These changes highlight a shift from simply reporting on energy use to actively implementing and demonstrating progress on energy-saving measures. Annual progress updates will also become a key requirement, emphasising the need to prove continuous effort.
