A Commercial Energy Performance Certificate (EPC) is an official document that shows the energy efficiency of a commercial property.
It provides an energy efficiency rating from A to G, showing how efficiently a building uses energy. The certificate also includes recommendations that may help improve the building’s energy performance and reduce energy consumption.
Commercial EPCs are required for many types of non residential buildings, including:
- Offices
- Shops and retail units
- Industrial buildings
- Warehouses
- Restaurants
- Hotels
- Public buildings
- Commercial rental properties
A Commercial EPC helps property owners, landlords, tenants and businesses understand the energy performance of a building and identify potential improvements.
Why Do You Need a Commercial EPC?
A valid Commercial EPC is an important requirement when certain commercial properties are:
- Sold
- Rented out
- Constructed
- Undergoing certain changes or improvements
The certificate provides useful information about a building’s current energy efficiency and helps prospective buyers or tenants understand expected energy performance.
For commercial landlords, maintaining EPC compliance supports responsible property management and helps meet current energy efficiency requirements.
For businesses, understanding the EPC rating can highlight opportunities to improve efficiency and reduce operating costs.
What Does a Commercial EPC Assessment Include?
During a Commercial EPC assessment, an accredited energy assessor reviews various aspects of the building that influence energy performance.
The assessment may include:
Building Structure and Construction
The assessor reviews the building’s construction type, age, size and materials to understand how efficiently it retains heat.
This may include:
- Walls
- Roofs
- Floors
- Building layout
Heating and Cooling Systems
Commercial heating and cooling systems have a major impact on energy performance.
The assessment may review:
- Boilers
- Air conditioning systems
- Heating controls
- Ventilation systems
- Temperature management systems
Lighting Systems
The assessor reviews the type and efficiency of lighting installed throughout the building.
Energy efficient lighting solutions can help reduce electricity consumption and improve EPC performance.
Insulation Levels
Insulation plays an important role in preventing heat loss.
The assessment may consider:
- Roof insulation
- Wall insulation
- Floor insulation
Windows and Glazing
Windows and doors are assessed to understand their impact on heat loss and overall building efficiency.
Factors may include:
- Glazing type
- Window efficiency
- Frame materials
Renewable Energy Features
Existing low carbon technologies may also be considered, including:
- Solar panels
- Heat pumps
- Renewable heating systems
How Is a Commercial EPC Rating Calculated?
A Commercial EPC rating is calculated using information collected during the building assessment.
The rating considers factors such as:
- Building size and usage
- Heating systems
- Cooling systems
- Lighting efficiency
- Insulation
- Energy consumption
- Renewable technologies
The final certificate provides:
Current Energy Rating
Shows the building’s existing energy performance.
Potential Energy Rating
Shows how the rating could improve if recommended measures are completed.
How Long Does a Commercial EPC Last?
A Commercial EPC is generally valid for 10 years unless a new certificate is produced earlier.
A new EPC may be required if:
- The existing certificate has expired
- Major building improvements have been completed
- Energy systems have been upgraded
- The property is being sold or rented
Keeping EPC records updated helps commercial property owners maintain compliance and understand ongoing energy performance.
