When it comes to energy efficiency, it’s not just homes that need to meet modern standards. Commercial and industrial buildings must also be assessed and certified. This is where the EPC rating for non-domestic properties becomes essential. Whether you’re a landlord, property manager, or business owner in Coventry or anywhere in the UK, understanding these ratings is crucial to remain compliant and energy-conscious. At Coventry Property Certification, we specialise in delivering accurate and reliable SAP EPC and non-domestic EPC services to help you meet regulatory requirements and enhance your property's value.

What Is a Non-Domestic EPC Rating?

An EPC rating for non domestic buildings, also known as a commercial EPC, provides an energy performance certificate for properties not used as dwellings. These include offices, shops, warehouses, factories, and other commercial spaces. Just like domestic EPCs, the rating ranges from A (most efficient) to G (least efficient). The rating is calculated based on the building’s energy usage, carbon emissions, insulation quality, heating systems, and more.

The purpose of the non-domestic EPC rating is to inform property owners, buyers, tenants, and investors about the building’s energy efficiency and potential energy-saving improvements. With sustainability becoming a business priority, an improved EPC can also help reduce operational costs and carbon footprint.

When Do You Need a Non-Domestic EPC?

A non-domestic EPC is legally required in the UK when:

• A commercial property is built

• A property is sold or rented out

• Major renovations or changes to heating and cooling systems are carried out

Failure to present a valid EPC rating for non-domestic buildings can lead to fines and penalties. That’s why it’s essential to consult professionals like Coventry Property Certification for timely, accurate assessments.

What Is SAP EPC?

SAP EPC stands for Standard Assessment Procedure Energy Performance Certificate. It is primarily used for newly built residential properties, conversions, or dwellings that have undergone significant change. SAP assessments are government-approved methods used to calculate energy performance and CO2 emissions.

Even though SAP EPC assessments are typically associated with residential properties, the methodology and data from SAP can still influence decisions around commercial buildings, especially mixed-use developments.

At Coventry Property Certification, we offer both SAP EPC for residential projects and non-domestic EPC services, ensuring all your properties comply with UK regulations.

EPC Ratings: Key Benefits for Non-Domestic Properties

Understanding and improving your EPC rating for non-domestic buildings comes with several advantages:

1. Legal Compliance

The UK government mandates that most commercial properties must have an EPC before being sold or leased. Compliance ensures you avoid fines and helps transactions proceed smoothly.

2. Energy Cost Savings

An efficient property costs less to run. A better EPC rating means your building uses less energy, leading to lower utility bills—a crucial benefit for any business.

3. Sustainability Goals

As environmental regulations tighten, a good EPC score supports your business’s sustainability efforts. It’s also great for public relations and stakeholder trust.

4. Increased Property Value

Energy-efficient properties are more attractive to tenants and buyers. A strong non-domestic EPC rating can add value to your commercial investment.

How EPC Ratings Are Assessed

For non-domestic properties, the EPC rating is calculated using the SBEM (Simplified Building Energy Model) methodology. The assessor will:

• Survey the building structure

• Evaluate lighting, ventilation, heating, and cooling systems

• Examine insulation, glazing, and other energy features

• Input data into approved software to generate the EPC

For SAP EPC, a different set of data inputs and calculations are used, mainly focusing on new build specifications and compliance with Part L of Building Regulations.

Common Mistakes to Avoid

1. Waiting until the last minute – Always schedule your EPC early to avoid delays in selling or renting.

2. Ignoring potential improvements – Small upgrades like LED lighting or better insulation can significantly boost your rating.

3. Using unqualified assessors – Always check your EPC provider is accredited and experienced, like our team at Coventry Property Certification.

How to Improve Your Non-Domestic EPC Rating

If your commercial property scores poorly, don’t worry—there are several ways to improve it:

• Upgrade heating and cooling systems to energy-efficient models

• Install double glazing and improve insulation

• Switch to LED or smart lighting

• Integrate renewable energy sources like solar panels

• Regularly maintain HVAC systems
