In today’s increasingly energy-conscious world, building efficiency and sustainable practices are no longer just options—they're necessities. Whether you’re a property developer, commercial landlord, or business owner, understanding the energy performance of your buildings is critical for cost-saving, regulatory compliance, and environmental responsibility. That’s where non domestic EPC certificates and SAP calculators come in.
Coventry Property Certification is at the forefront of this transition. Specialising in energy assessments for both domestic and non-domestic properties, our experienced professionals help you stay ahead of regulations while achieving optimal energy efficiency. Let’s dive deeper into what these certificates and tools mean for your commercial property ventures.
What Is a Non Domestic EPC Certificate?
A non domestic EPC certificate—short for Energy Performance Certificate—is a legally required document that rates the energy efficiency of a commercial or public property. It assigns a grade from A (most efficient) to G (least efficient), based on factors like insulation, heating systems, lighting, and construction type.
These certificates are mandatory for all commercial buildings that are sold, leased, or constructed in the UK. Without one, property owners risk legal fines, failed transactions, and reputational harm. Coventry Property Certification delivers fully compliant, fast, and affordable non-domestic EPC assessments across a wide range of property types including:
Warehouses and factories
Office spaces and retail units
Hotels and restaurants
Educational and healthcare buildings
Our assessors use advanced software and on-site inspections to provide a detailed report that helps you understand your building's current performance and actionable ways to improve it.
Importance of Energy Ratings in Commercial Properties
Energy ratings are no longer just a formality—they influence property value, rental desirability, and operational cost. Commercial tenants and buyers increasingly favour buildings that demonstrate energy efficiency, both to lower their utility bills and meet corporate environmental goals.
Moreover, regulations are tightening. The UK Government’s Minimum Energy Efficiency Standards (MEES) now require most rented commercial buildings to meet at least an E rating—with plans to push that minimum to B rating by 2030. Upgrading your building today with guidance from Coventry Property Certification could save you from costly retrofits and compliance issues in the future.
How a SAP Calculator Enhances Energy Planning
The SAP calculator, or Standard Assessment Procedure calculator, is another vital tool—especially during the planning and design stage of new builds. While SAP is more commonly associated with domestic properties, a similar methodology is used in SBEM (Simplified Building Energy Model) for non-domestic properties.
SAP calculations predict a building’s energy performance before it's built, based on detailed inputs such as:
Wall, floor, and roof insulation
Heating system type and efficiency
Window glazing and orientation
Renewable energy sources
Air tightness levels
By simulating energy use, the SAP calculator allows architects, developers, and consultants to tweak the design for better efficiency, lower carbon emissions, and compliance with Building Regulations Part L.
Coventry Property Certification provides expert SAP and SBEM calculations for new builds, helping you ensure compliance from the very first blueprint.
Who Needs a Non Domestic EPC Certificate?
Any commercial property owner planning to sell, rent, or build a non-domestic structure in England, Wales, or Northern Ireland needs an EPC certificate. It applies to:
Retail shops
Restaurants
Office blocks
Schools and universities
Industrial buildings
Hotels
There are a few exemptions—like buildings set for demolition, places of worship, or properties smaller than 50m² not intended for sale or rent. Still, in most cases, the absence of a valid EPC can halt transactions or trigger penalties up to £5,000.
Coventry Property Certification ensures that your EPC process is stress-free, legally compliant, and delivered on time. We also advise on improvements you can make to boost your rating, such as upgrading lighting to LED or installing high-efficiency boilers.
When Should You Use a SAP Calculator?
A SAP calculator should be used before construction begins on any new residential or mixed-use development, and in some major renovations or conversions. At this stage, it’s easier—and cheaper—to adjust designs for better performance rather than making changes post-construction.
Key benefits of using a SAP calculator include:
Avoiding failed building control sign-offs
Reducing long-term energy bills for occupants
Qualifying for government grants or incentives
Demonstrating compliance with carbon targets
Improving future marketability
Coventry Property Certification’s experienced assessors use government-approved software to produce reliable SAP reports that can be submitted to building control, ensuring your project runs smoothly from start to finish.
