Commercial Energy Performance Certificates (EPC)
Accredited Level 3, 4, and 5 Non-Domestic Energy Assessments
What is an EPC?
An Energy Performance Certificate (EPC) provides an official asset rating for a commercial building on an alphabetical scale from A to G. This rating reflects the calculated energy efficiency of the property, evaluating critical infrastructure including heating, cooling, ventilation, lighting systems, building controls, fabric envelope insulation, and any integrated low-carbon technologies like solar PV arrays.
At Up Energy, our experienced in-house non-domestic energy assessors hold the top-tier accreditations required to execute Level 3, Level 4, and Level 5 EPCs across all commercial sectors, including:
Hotels, guest houses, and care homes
High-street retail shops and supermarkets
Commercial offices and deep-plan corporate headquarters
Industrial units, warehouses, and distribution centres
Schools and public sector educational facilities
MEES Compliance Alert: Under current UK legislation, commercial properties must satisfy strict Minimum Energy Efficiency Standards (MEES) to be legally let or sold. Contact our team to review your risk portfolio and safeguard your commercial assets.
When is a Non-Domestic EPC Required?
By law, a valid Commercial EPC must be commissioned and made available whenever a non-domestic property is:
Constructed (For new builds under Part L, see our dedicated SBEM Calculations page).
Marketed for Sale
Leased or Let to a tenant
Once lodged on the central register, a commercial certificate remains valid for 10 years. However, we highly recommend commissioning a fresh assessment if significant alterations are made to the building fabric or the HVAC infrastructure during that decade.
Every certificate is delivered alongside a comprehensive Recommendations Report. This statutory document outlines customised, practical interventions designed to elevate your property's energy rating, neatly categorised by short, medium, and long-term financial payback periods.
EPC Exemptions & Specialised Guidance
While the majority of commercial buildings require certification, specific statutory exemptions apply to listed properties, designated places of worship, temporary structures, and buildings scheduled for imminent demolition under planning consent.
Our compliance team helps landlords, commercial agents, and solar PV installers accurately identify valid exemptions, providing official EPC Exemption Letters where required. We guide you through complex regulatory frameworks to protect your project against local authority compliance penalties.
Frequently Asked Questions
-
Energy Performance Certificate. The certificate contains the EPC rating.
-
An EPC is required under UK law when you are selling or letting a domestic or non-domestic (commercial) building. You may also need one as part of your application for the Feed-in Tariff.
-
Some non-domestic buildings are exempt from an EPC such as places of worship, buildings due for demolition, Listed buildings and those under 50m2. Ofgem has its own view on EPC exemptions, so if you are applying for a Feed-in Tariff, you may still need one even if one of the above conditions applies – contact us for some guidance.
-
An EPC involves a site visit to collect data about the building fabric, heating, ventilation and cooling systems, lighting and hot water.
-
For a small domestic EPC, it may only take around 30 minutes on site. For a commercial EPC, the time taken will depend on the size and complexity of the building; anything from 30 minutes to several hours.
-
The EPC scale goes from A to G, A being better.
-
For a commercial building, the rating gives you an indication of the energy performance of the building, in terms of CO2 emissions. For a domestic building, the rating gives you an indication of the energy costs involved in running the house.
-
Domestic EPCs are cheaper than commercial EPCs, as there is much less information to be collected and the buildings tend to be smaller. The cost depends on the size and complexity of the building. Contact us for a no obligation quote.

![Five gold stars, indicating a five-star rating]()
"I had to produce a very quick EPC survey for a commercial lease. Having initially been quoted and let down by a national company I was concerned the deal would fall through. However Simon very quickly sorted everything out and surveyed that morning. Cannot recommend enough."
