ESOS Compliance & Energy Audits

Turn ESOS or EED compliance into a structured approach to performance, efficiency and decision-making.

Organisations are facing increasing pressure to understand, manage and improve energy performance through regulatory frameworks such as the Energy Savings Opportunity Scheme (ESOS) and Energy Efficiency Directive (EED). As expectations continue to evolve, organisations are being asked not only to identify opportunities for improvement, but to demonstrate how they are acting on them.

In practice, this often exposes wider challenges. Data is fragmented, ownership sits across multiple teams, and energy audits are disconnected from decision-making. As a result, compliance can become resource-intensive without improving performance visibility or supporting meaningful action.

The challenge is not just meeting ESOS requirements, but using the process to build a clearer, more consistent approach to energy performance across the business.

We help organisations deliver ESOS compliance efficiently while strengthening data, governance and performance insight to support better business decisions.

How organisations should approach ESOS compliance

Organisations subject to ESOS must meet regulatory requirements, but the way they approach compliance can significantly improve how energy performance is understood, managed and improved across the business.

A structured approach to ESOS enables organisations to:

Ensure compliance with evolving ESOS reporting requirements: Deliver compliant audits, action plans and progress reports while reducing regulatory risk.
Build a consistent and reliable energy data foundation: Address fragmented energy data to improve reporting accuracy, confidence and audit readiness.
Improve visibility of energy performance: Identify inefficiencies, track consumption and understand where action is needed.
Prioritise energy efficiency opportunities: Translate audit findings into practical opportunities that support cost reduction, operational improvement and decarbonisation objectives.
Support better operational and investment decisions: Use energy performance insights to prioritise resources, assess business cases and support long-term improvement programmes.

How we support ESOS compliance

We offer flexible support across every stage of the ESOS process, from qualification and audit delivery through to action plans, progress reporting and regulatory submissions. Support can be tailored to your requirements, whether you require Lead Assessor sign-off, support with specific elements of compliance, or a fully managed ESOS programme.

ESOS qualification and compliance planning – Confirm organisational scope, reporting boundaries and compliance obligations, ensuring a clear and efficient route to compliance.
Energy audits and site assessments – Deliver compliant ESOS audits through site visits, energy analysis and transport assessments, identifying practical opportunities to improve energy performance.
ESOS reporting, submissions and action plans – Prepare compliance reports, support Director sign-off, manage submissions and develop action plans aligned to ESOS requirements.
ESOS compliance and performance improvement – Support annual progress updates while strengthening energy data, performance visibility and wider net zero objectives.

We also support organisations subject to European Energy Efficiency Directive (EED) requirements, applying the same structured approach across European operations.

ESOS is no longer a four-yearly audit exercise

The structure and expectations of ESOS are changing significantly. What was previously a periodic audit requirement is now evolving into a continuous, evidence-led compliance and delivery programme.

Our ESOS Phase 4 compliance approach

Acclaro supports organisations through ESOS Phase 4 and beyond, delivering compliance, audit-ready submissions while strengthening underlying energy data, governance and decision-making.

Our approach combines regulatory compliance with practical energy performance insight, ensuring ESOS delivers value beyond the submission itself.

Confirm scope, organisational boundaries and audit requirements. We establish the audit approach, mobilise data collection and creates a clear route to compliance.

Undertake site visits, energy assessments and transport audits to understand energy use and identify opportunities for improvement across your operations.

Analyse audit findings, quantify potential savings and develop a prioritised register of energy efficiency opportunities, including costs, payback periods and implementation considerations.

Undertake internal review and Lead Assessor oversight to ensure outputs are robust, consistent and aligned with regulatory requirements.

Prepare the final ESOS report, supporting evidence pack, Director sign-off documentation and Environment Agency submission
