What is a Commercial BER Certificate?
Commercial Building Energy Ratings (BERs) are a legal requirement for non-domestic buildings in Ireland. They provide an ‘asset rating’ that measures your building’s energy efficiency on a scale from A to G, based on its design and systems rather than actual usage. This standardised assessment helps buyers and tenants understand potential energy costs, identifies improvement opportunities, and demonstrates regulatory compliance. A BER isn’t just a legal obligation for property owners—it’s a valuable tool that can enhance property value, reduce operational costs, and showcase your commitment to sustainability.
When is a Commercial BER required?
A Commercial BER certificate must be provided when a non-residential building is being constructed, sold, or rented. The certification remains valid for 10 years unless significant changes are made to the building’s fabric or systems. Exemptions include Protected Structures, Temporary Buildings, Places of Worship, Non-Residential Agricultural Buildings with minimal heating requirements, and Buildings Formally Scheduled for Demolition under current regulations.

What is a Commercial BER used for?
A Commercial BER determines a property’s energy efficiency, providing details on energy usage (kWh/m²) and carbon emissions (kg/m²) per year. This standardised assessment helps potential buyers and tenants understand expected operating costs and compare different properties. The rating serves as a benchmark for property valuation, regulatory compliance, and identifying cost-effective energy efficiency improvements that could enhance building performance.
Our Accreditations & Qualifications
Which Businesses Need a BER?
A Commercial BER Cert is mandated when a commercial property is sold, rented, or occupied for the first time, ensuring compliance and transparency in energy efficiency standards. Commercial BER Certs are essential for various properties or units, such as office blocks, apartment blocks, retail units, shopping centres, hotels and bars, industrial buildings, leisure centres, nursing homes, and doctor/dentist practices.

How Your Commercial BER is Calculated
A comprehensive Commercial BER assessment involves specialised methodology and expert analysis. Our qualified assessors use the standardised Non-Domestic Energy Assessment Procedure (NEAP) and approved software to transform your building’s physical characteristics into an accurate energy rating.
How We Calculate Your BER
Our assessors survey your property and input the collected data into iSBEM, the official software used to calculate the BER. The process includes analysing your building’s design, construction elements, heating, ventilation, lighting systems, and more. The software then calculates your building’s energy performance on the standardised A to G scale, providing clear insight into its efficiency.

Understanding BERs vs DECs: What’s the Difference?
Building Energy Rating (BER)
A BER is a standardised assessment of a building’s energy efficiency based on its design and fixed systems. It uses typical assumptions about occupancy and energy use, considering features like insulation, heating, ventilation, and lighting. Valid for ten years, a BER is legally required when constructing, selling, or leasing a commercial building. It measures design performance rather than real-time or operational energy consumption.
Display Energy Certificate (DEC)
A DEC is an operational energy rating that reflects the actual measured energy use of a building over a 12-month period. It captures real consumption during occupancy and benchmarks performance against similar buildings. DECs must be renewed annually and are required for public buildings over 250m² and commercial properties over 500m². It includes both regulated and unregulated energy use, promoting public transparency and energy awareness.
Our Simple Three-Step BER Process
We begin with a consultation to understand your requirements. Our certified assessors carry out a detailed site survey, documenting the building’s layout, systems, and energy characteristics to establish a reliable baseline for your commercial property’s BER assessment.
We analyse your building’s data using SEAI-approved software and the official NEAP methodology. This generates a certified Commercial BER, which includes an A–G asset rating and carbon emissions figure, fully compliant with Irish energy regulations and building performance standards.
You will receive a detailed report with energy-saving recommendations and ongoing support, including implementation assistance and compliance advice to enhance energy performance while adhering to Ireland’s commercial building energy regulations for optimal efficiency.
