What are Display Energy Certificates?

Display Energy Certificates (DECs) are mandatory in the UK for most public buildings. These certificates are an integral part of the Energy Performance of Buildings Directive (EPBD) regulations and serve to demonstrate a building's energy efficiency. The certificates use a scale of measurement ranging from A to G, with A being the most energy-efficient and G being the least. To comply with the EPBD regulations, public buildings must display a valid DEC if they meet the following criteria:
• Total floor area of over 250m2
• Partially occupied by a public organization
• Accessible by the general public

By displaying a valid DEC, public buildings can demonstrate their commitment to sustainability and energy efficiency. It also helps building owners and managers identify areas where they can improve energy efficiency and reduce energy costs. If you are a public building owner or manager, ensure you have a valid DEC displayed in your building to comply with legal requirements and showcase your commitment to sustainability.

What are the renewal requirements and advisory reports for Display Energy Certificates?

Display Energy Certificates (DECs) are an important legal requirement for public buildings in the UK, helping to demonstrate the energy efficiency of the building to the public. Renewal requirements for DECs differ depending on the size of the building. For buildings with a total useful floor area of over 1000m2, DECs must be renewed on an annual basis. This ensures that the energy performance of the building remains up to date and that any improvements made to the building's energy efficiency are reflected in the certificate. In contrast, buildings between 250m2 and 1000m2 only need to renew their DECs every ten years.

While less frequent, it is still important to ensure that the building's energy performance is accurately reflected in the DEC, and to make any necessary improvements to the building's energy efficiency. In addition to the Display Energy Certificate, an advisory report is provided by the energy assessor. The report outlines recommendations for improving the energy efficiency of the building, potentially reducing energy costs and improving overall sustainability. The length of time the advisory report remains valid depends on the size of the building. For buildings over 1000m2, the advisory report is valid for seven years. Meanwhile, for buildings ranging between 250m2 and 1000m2, the advisory report lasts for ten years. This ensures that any recommendations made in the report remain relevant and useful for building owners and managers.

It is important to note that while renewing DECs is a legal requirement, an energy survey is not mandatory. However, conducting an energy survey can provide useful insights into the building's energy consumption and identify areas for improvement. Energy surveys can help to reduce energy costs, improve the building's sustainability, and help comply with other legal requirements such as the Minimum Energy Efficiency Standards (MEES) regulations.

What is the process of acquiring a Display Energy Certificate?

Firstly our team will need 12 months of consecutive energy data for your property. Additionally, any floor plans you can provide will also help our team to provide the most accurate quote. Once you are happy to proceed, our dedicated project management team will work with you to organize the most convenient date for our assessor to visit site. Once on site they will conduct a thorough survey of the property, both internally and externally. They will assess everything from the fabric of the building, to the way each area of the building is used. This information along with the annual consumption data helps them to issue a specific energy rating for the property. Moreover, it helps the assessor to identify areas of inefficiency which will be highlighted in the advisory report. After the survey has been completed, our DEC assessor will collate all of the data and produce a rating, certificate and advisory report. Draft copies will be sent for your approval and when you are happy, we will lodge them on the national landmark register.
