Commercial EPC

Commercial 
Energy Performance Certificates 
(Non-Domestic).

To certify how energy efficient a property is by using a rating system from A-G. You must provide a commercial EPC to any prospective new tenant or buyer. It must also be included with any other written information provided. A penalty is incurred if you fail to make an EPC available to prospective tenants or buyers. The rate is 12.5% of the value of the property (minimum of £500 to a maximum of £5,000). Don't fall short of your responsibilities & reach out to our expert team.

Display Energy Certificate (DEC)

The energy performance of public buildings can be assessed and rated using a specific system. The rating is valid for a specific period of time, which depends on the floor area of the building being assessed. For instance, some buildings may require a rating that is valid for one year, while others may need a rating that is valid for ten years.

What is an EPC Rating for Commercial Buildings?

Litegreen's team of experts can provide comprehensive support to commercial property owners and managers in obtaining an accurate and up-to-date EPC for their building. Our accredited assessors use approved methods and government-approved energy modelling software to carry out a thorough site audit and simulation of the building, producing a detailed report with recommendations for energy efficiency improvements.

With Litegreen's expertise, commercial property owners can ensure that they meet their legal obligations and avoid penalties for failing to provide an up-to-date EPC to prospective tenants or buyers. Our team can guide you through the process and provide tailored advice on how to improve the energy efficiency of your building, reducing energy costs and carbon emissions.

How are Commercial EPC's Calculated?

When it comes to creating a commercial Energy Performance Certificate (EPC), every detail matters. Our team takes into consideration all aspects of the building, from the lighting and HVAC system to the materials used for insulation and construction.

It's important to note that commercial EPC assessments require the expertise of a fully qualified and accredited Non-Domestic Energy Assessor (NDEA), as opposed to a domestic energy assessor (DEA).

Our experienced NDEA will carefully evaluate the building's size, insulation, and HVAC system to determine its energy efficiency rating. EPC Certificates are graded on a scale from A-G, with A being the most efficient and G being the least efficient.

Achieving an A grade (with a rating of 0-25) is the best result possible, indicating that the building has zero net annual CO2 emissions. Trust our team to provide a thorough and accurate assessment of your building's energy performance.

 When are commercial EPC's needed?

There are exceptions to when an EPC is not required:

If a building is to be demolished.
Temporary buildings with less than two years of usage.
An entirely detached building with a total useful floor area of less than 50m2, and not a dwelling.
Places of worship.
Industrial sites, workshops and non-residential agricultural buildings with low energy demand.

In certain circumstances, an Energy Performance Certificate (EPC) may not be required for a building. The following are exceptions to when an EPC is not required:

  1. Buildings that are to be demolished.
  2. Temporary buildings that are to be used for less than two years.
  3. Detached buildings that have a total useful floor area of less than 50m2 and are not intended for use as a dwelling.
  4. Places of worship.
  5. Industrial sites, workshops, and non-residential agricultural buildings with low energy demand.
It is important to note that these exceptions may vary depending on the country or region in which the building is located. If you are unsure whether your building requires an EPC, it is best to consult with a qualified and accredited energy assessor. At Litegreen, our team of experts can provide you with the necessary guidance and support to ensure that you meet your legal obligations and achieve the highest level of energy efficiency for your building.
