Commercial EPC Assessments

Commercial Energy Performance Certificates (EPCs) in the UK

​

An Energy Performance Certificate (EPC) is an essential document that provides an assessment of your commercial property’s energy efficiency. An EPC is generally required on construction, sale or letting, subject to exemptions. Certain changes to separately occupied parts and fixed services can also trigger the requirement; an ordinary refit does not automatically do so. The EPC evaluates various factors, including the building’s structure, insulation, and fixed heating, ventilation, and cooling systems. However, it’s important to note that EPCs do not account for how these systems are utilised by current occupants.

​

EPCs help property owners, landlords, and tenants understand how energy efficient their building is and identify potential areas for improvement. Improvement measures may reduce energy use and emissions, but an EPC rating alone does not guarantee bill savings or comfort. Costs, controls, building use and installation design need separate consideration.

​

EPC Assessment Levels: Understanding Building Complexity

​

EPCs are assigned ratings based on the building’s energy efficiency, from A to G, with A representing the most energy-efficient buildings and G the least. However, there are different levels of EPC assessments, which determine the complexity of the evaluation required:

​

• Level 3 and Level 4 EPCs: These are typically assessed using SBEM (Simplified Building Energy Model) software. SBEM is suitable for most non-domestic buildings, offering a straightforward assessment of energy efficiency based on the building’s size, type, and fixed systems.

• Level 5 EPCs: More complex properties, such as large, mixed-use developments or those with intricate heating and cooling systems, require a more detailed approach. Level 5 assessments use Dynamic Simulation Modelling (DSM) software, which provides a comprehensive, dynamic analysis of how energy flows within the building under various conditions.

​

Each level of EPC assessment is designed to match the building’s complexity and accurately reflect its energy performance.

Non-Intrusive Site Surveys: Minimal Disruption to Your Operations

​

At NRG, we understand that your business operations are a priority, which is why our site surveys are non-intrusive. Our qualified assessors gather all the necessary data to produce an accurate EPC without causing disruption to you, your staff, or your processes. The survey typically involves inspecting key building systems (such as heating, lighting, and ventilation) and collecting details about insulation, glazing, and any renewable energy systems in place. This means you can carry on with your business as usual while we conduct the assessment.

​

Improving Low EPC Ratings

​

An F or G rating does not itself prevent a commercial property from being sold. For privately rented non-domestic properties within the scope of MEES in England and Wales, the current minimum is EPC E unless a valid exemption is registered. We can model suitable improvements before you commit to works.

We provide tailored advice on how to enhance the energy efficiency of your property, including recommendations for upgrading insulation, improving lighting systems, and implementing energy-saving technologies. Our team can help guide you through the steps required to meet MEES and ensure your property is fit for the market.

EPC Validity & Access

​

EPCs are valid for 10 years. Once your EPC is lodged on the official government register, you can easily access it at any time, ensuring it’s available whenever required by potential buyers, tenants, or regulatory bodies.

An EPC register is maintained by the government, providing a secure and centralised database where your certificate is stored. This register can be accessed by the public to verify EPC information, making it easier for you to demonstrate compliance when needed.

​

Why Choose NRG for Your EPC Assessment?

​

At NRG, our assessors are fully qualified and experienced in conducting EPC assessments in strict adherence to UK government legislation. We take pride in providing accurate, reliable, and professional energy performance certificates, helping our clients comply with regulatory requirements while optimising their properties for energy efficiency.

By improving your EPC rating, you not only meet legal obligations but also benefit from:

​

• Lower energy costs: More efficient buildings consume less energy, leading to reduced operational costs.

• Reduced CO2 emissions: A higher EPC score can contribute to your sustainability goals, lowering your building’s environmental impact.

• Increased property value: Properties with a high EPC rating are generally more attractive to prospective tenants or buyers, potentially increasing their value.​

​

What Does Your EPC Report Include?

​

Once the EPC assessment is complete and lodged with the government, you’ll receive your EPC certificate in PDF format. The report includes:

1. Energy Performance Rating: A graph that rates the building’s energy efficiency from A to G, with A being the most energy-efficient and G the least.

2. Recommendation Report: A detailed list of suggestions for improving the building’s energy efficiency. This could include practical measures such as upgrading insulation, replacing inefficient boilers, or installing energy-efficient lighting and heating systems.

3. Improvement options: the recommendation report identifies potential measures. A separate modelling assessment can compare their predicted EPC effects; actual bill savings and installation costs need separate assessment.

4. Carbon Footprint: Your EPC will indicate the property’s carbon emissions, giving you a clearer picture of its environmental impact and helping you meet carbon reduction targets.
