Navigating energy performance certification is essential for UK commercial property owners. Energy Performance Certificates (EPCs) and Display Energy Certificates (DECs) serve distinct purposes with unique requirements. EPCs assess theoretical energy efficiency based on building design, whilst DECs measure actual consumption using utility data. Understanding EPC and DEC differences ensures compliance with Minimum Energy Efficiency Standards (MEES), reduces operational costs, and enhances property value. From April 2027, all tenanted commercial properties must achieve EPC B rating under MEES Phase 2. Both certificates align with Environmental, Social, and Governance (ESG) goals, supporting the UK’s net-zero ambitions. Vital Direct provides expert guidance to optimise energy efficiency and meet regulatory demands for commercial landlords, asset managers, and facilities managers.
