In 2026, Commercial Energy Performance Certificates (EPCs) are a legal requirement for every non-domestic property that is sold, rented, or leased. Understanding what happens during a commercial EPC assessment and how to prepare your building can save time, reduce costs, and ensure compliance with UK energy regulations.
This guide will cover what to expect during a Commercial EPC assessment, why it matters, costs, and preparation tips for building owners, landlords, and property managers.
What Is a Commercial EPC?
A Commercial EPC assesses the energy efficiency of non-domestic buildings, including:
Offices and business parks
Retail shops and malls
Warehouses and industrial units
Hotels, restaurants, and leisure facilities
The certificate provides:
Energy efficiency rating (A to G)
Recommendations to improve energy efficiency
Guidance on reducing energy costs and carbon emissions
Unlike domestic EPCs, commercial assessments are more detailed due to larger spaces, multiple energy systems, and varied occupancy patterns. For professional services, see Commercial EPC Assessments.
Why Commercial EPC Assessments Are Important in 2026
1. Legal Compliance
All commercial properties in the UK must have a valid EPC when:
Sold
Leased
Rented
Failing to provide a certificate is illegal and can result in financial penalties.
Commercial EPCs are valid for 10 years, but you must ensure the certificate is up-to-date before any transaction. You can book a Commercial EPC with EPCrate to stay compliant.
2. MEES Compliance
The Minimum Energy Efficiency Standards (MEES) require commercial rental properties to meet a minimum EPC rating, usually E or higher.
A professional assessment ensures your building:
Complies with MEES regulations
Identifies improvements needed to meet energy standards
Avoids fines and letting restrictions
Learn more about MEES and EPC requirements on our About Us page.
3. Protects Property Value and Attractiveness
Commercial EPCs impact tenant demand, investor confidence, and building valuation.
Buildings with strong ratings attract higher rents and faster tenants.
Poor ratings can reduce appeal, delay lease agreements, and affect market value.
An EPC assessment provides insight into where improvements can boost efficiency and increase profitability.
What Happens During a Commercial EPC Assessment?
A commercial EPC assessment involves a site visit by a certified assessor. The process typically includes:
Building inspection
External and internal fabric
Roof, walls, floors, and insulation
Energy systems review
Heating, cooling, and ventilation
Lighting systems
Renewable energy installations, if any
Usage patterns and zoning
Occupancy levels
Different areas or floors with varied energy needs
Data analysis
Energy consumption calculations
Carbon emissions estimation
Recommendations report
Efficiency improvements
Cost-effective energy upgrades
Potential environmental impact reduction
The assessment time depends on building size and complexity but typically ranges from 2 to 6 hours.
The certificate is then issued digitally and lodged with the official EPC register, making it valid for 10 years.
How to Prepare Your Commercial Property
Proper preparation ensures a smooth and accurate EPC assessment. Here’s what building owners and managers should do:
1. Gather Building Information
Prepare documents such as:
Floor plans and building layouts
Previous EPCs (if any)
Heating and cooling system specifications
Energy bills (if available)
2. Check Energy Systems
Ensure that:
Heating and cooling systems are functioning correctly
Lighting and electrical systems are operational
Any recent energy upgrades are documented
3. Clear Access
Make all areas accessible, including:
Roof spaces
Plant rooms
Office floors and storage areas
4. Communicate with Occupants
Notify tenants and staff about the assessment to avoid disruptions during the inspection.
By preparing in advance, the assessor can work efficiently, resulting in a more accurate EPC rating.
