What Is a Non-Domestic EPC?
A Non-Domestic EPC (Energy Performance Certificate) is an official document that describes the energy efficiency of a building that is not used as a home. It provides a calculated rating for the property, typically on a scale that helps owners, tenants, and potential buyers understand how energy-efficient the space is. The certificate also includes recommendations for improving energy performance, such as upgrading lighting or improving insulation where appropriate. In the UK, Non-Domestic EPCs are commonly required for many types of commercial properties, including offices, shops, warehouses, and other non-residential buildings.
Non-Domestic EPCs are designed to encourage energy efficiency and transparency in the commercial property market. They’re not the same as domestic EPCs for homes, because the assessment methods and requirements are tailored to how non-domestic buildings are used and operated. A key part of the process is that the energy performance is modelled based on the building’s characteristics, services, and energy-related information. For many owners and managing agents, having a correct Non-Domestic EPC is an essential part of staying compliant and avoiding preventable delays with transactions or letting arrangements.
At PropCert.co.uk, we support landlords, estate agents, commercial property owners, and businesses across the UK with Non-Domestic EPCs and wider compliance inspections. If you’re managing a commercial portfolio, we can help ensure EPC documentation is completed correctly and in line with current expectations. We also provide related services that frequently sit alongside EPCs, helping you streamline compliance planning. This can be particularly helpful when refurbishments, sales, or leasing events trigger multiple certification requirements at the same time.
How a Non-Domestic EPC Is Assessed
A Non-Domestic EPC is produced by an accredited assessor using approved software and assessment procedures. The survey and data collection stage is important because the certificate is only as accurate as the information gathered about the building. For many properties, the assessment considers elements such as the building’s construction, floor areas, services (heating, hot water, and ventilation), and energy-related equipment. Where systems are present, the assessor may also review information such as boiler details, controls, and the operation of ventilation and lighting.
Non-domestic assessments can also reflect occupancy patterns and how the building is intended to be used. Different building types require different approaches—for example, energy use in an office differs from that of a warehouse, shop, or leisure facility. That’s why it’s important that the correct building type and usage profile are selected during the assessment. A robust process helps you avoid underestimating or overestimating performance, which could affect future compliance planning and leasing discussions.
Because commercial buildings are diverse, some assessments may require additional evidence or access to plant rooms and service spaces. If your property has undergone recent upgrades, such as replacing boilers, adding insulation, or improving lighting with LEDs, those improvements can influence the EPC outcome. Equally, missing or inaccessible information can lead to assumptions being used, which may reduce the certificate’s accuracy. Our team at PropCert.co.uk can guide you on what’s typically needed so you can prepare your property effectively before the assessment takes place.
Why Non-Domestic EPCs Matter for Landlords and Business Owners
Non-Domestic EPCs matter because they support legal compliance, help drive energy efficiency improvements, and provide clarity for stakeholders. They are frequently required when a commercial property is sold, leased, or offered for rent under the applicable regulations. For many landlords and estate agents, an EPC is also a key part of marketing and due diligence, because it communicates expected energy performance to buyers and tenants. A clear, accurate Non-Domestic EPC can therefore reduce friction during negotiations and help prevent delays caused by missing or outdated documentation.
Energy performance information can also influence decisions around refurbishment and budgeting. The recommendations on the EPC highlight practical improvements that could reduce energy consumption and operating costs. Even when a certificate doesn’t force immediate changes, it often becomes a starting point for planning improvements such as upgrading lighting, enhancing heating controls, or improving building fabric. For commercial owners, these actions can be valuable not just for compliance, but for reducing overheads and improving sustainability credentials.
Non-domestic EPCs can be particularly relevant for larger buildings and portfolios, where energy efficiency measures may be planned across multiple sites. If you manage commercial assets, you may also face wider compliance and inspection obligations alongside EPCs. PropCert.co.uk helps you coordinate compliance where possible, so you can address EPC requirements alongside other essential certifications such as EICRs, fire risk assessments, asbestos surveys, and gas safety where applicable. Building compliance is rarely “one-and-done,” and having a single trusted provider can simplify the overall process.
