What is a Commercial DEC?

A Display Energy Certificate (DEC) is a legal requirement for public buildings in the UK that are over 250 square metres in floor area and are frequently visited by the public. DECs are designed to show the actual energy usage of a building over the course of a year, rather than the theoretical efficiency of the building’s design.

Who Needs a Commercial DEC ?

If you operate a public building in England, Wales, or Northern Ireland that meets the following criteria, you are legally required to display a valid DEC:

1. The building is over 250m² in total useful floor area.

2. It is occupied by a public authority (such as a council, school, college, library, or hospital).

3. It is frequently visited by the public (not just staff or contractors).

Examples of buildings that need DECs include:

a. Local Authority Offices

b. Schools & Universities

c. Museums & Libraries

d. Hospitals & Healthcare Centres

Our DEC Process: What to Expect

At Gradwell Group, we’ve streamlined the DEC process to make it hassle-free:

1. Initial Consultation

We begin by understanding your building type, size, and usage to determine the appropriate level of certification required.

2. Data Collection & Site Survey

We collect your 12 months’ worth of energy usage data (electricity, gas, etc.) and conduct an on-site inspection to gather building data.

3. Energy Analysis

Using government-approved software, we calculate the building’s Operational Rating (OR) and generate the Display Energy Certificate.

4. Advisory Report Generation

We create an Advisory Report detailing energy-saving recommendations tailored to your building.

5. Certificate Delivery & Display

We provide digital and print-ready copies of your DEC and Advisory Report—ready for public display and submission to relevant authorities.
