Large UK organisations must complete an ESOS audit every four years to review energy use and identify opportunities to cut consumption and emissions. The next deadline is 5 December 2027 for Phase 4. Key changes include the removal of Display Energy Certificates (DECs) and Green Deal Assessments (GDAs) as compliance routes, and a new requirement to report on progress against ESOS Action Plans, with explanations if commitments are not met.
ARO simplifies compliance by managing audits, data, and reporting while preparing your business for these updates. Our approach turns obligations into opportunities for cost savings, carbon reduction, and long-term efficiency.
