A Commercial EPC (Energy Performance Certificate) is a mandatory assessment for non-domestic properties, showing how energy-efficient a building is. The certificate rates properties from A (most efficient) to G (least efficient) and includes recommendations for improvement.

In 2026, stricter MEES (Minimum Energy Efficiency Standards) enforcement, legal obligations, and sustainability targets make it essential for landlords, investors, and developers to understand Commercial EPC requirements, costs, and compliance strategies.

Why a Commercial EPC Is Important

  • Legal Compliance: EPC is required before selling, letting, or refurbishing a commercial property.

  • MEES Compliance: Properties below minimum rating (currently E) cannot be legally let.

  • Financial Planning: EPC recommendations can guide energy-saving upgrades and reduce long-term costs.

  • Asset Value: Higher-rated buildings are more attractive to tenants and investors.

Which Properties Require a Commercial EPC?

Commercial EPCs are required for:

  • Offices

  • Retail units

  • Industrial warehouses

  • Mixed-use commercial buildings

  • Newly built or refurbished commercial properties

Even if the building already has a certificate, reassessment may be required after renovations or energy system upgrades.

Commercial EPC Costs in 2026

Pricing varies by property type, size, and location:

  • Small offices/retail units: £180 – £300
