Large UK-based enterprises must participate in ESOS if they meet the qualifying criteria, which include employee headcount, turnover and energy consumption. We begin with a full eligibility review, analysing your corporate group structure, UK operations, energy baseline and whether you fall under the ESOS regime. Understanding your obligation means you can move proactively not just to tick a box, but to leverage the assessment for broader energy strategy and cost-reduction.


Under ESOS you must audit your energy use, identify significant areas of consumption and produce a compliance notification to the regulator. We coordinate the full assessment process: gathering site-level data, engaging lead assessors, completing the audit report and submitting your notification.We ensure timelines, accuracy and audit trail are maintained. A robust ESOS assessment not only fulfils your legal requirement but also surfaces energy-saving opportunities you may not otherwise discover.
Beyond compliance, ESOS provides a platform for actionable improvement. Identifying cost-effective energy-saving measures is integral to the scheme. Our service maps the assessment outcomes into a tailored action-plan, linking the identified energy-savings to your procurement, metering, efficiency and sustainability strategies. By aligning implementation with business goals, you convert this regulatory requirement into real cost savings, improved carbon performance and stronger operational resilience.
