Display Energy Certificates

A local authority can issue a penalty charge notice of £500 for failing to display a DEC at all times in a prominent place clearly visible to the public, and £1,000 for failing to possess or have in their control a valid advisory report. In addition to these penalties, it will still be necessary to commission the documents otherwise further offences will be committed.

What is a Display Energy Certificate?

Display Energy Certificates are a legal requirement for most public buildings in the UK. Included as part of the EPBD regulations, their purpose is to show the energy performance of a particular building. The scale of measurement runs from A to G- A being the most efficient and G being the least efficient. Public buildings must ensure a valid certificate is displayed if it meets the following criteria: -A total floor area of over 250m2 -At least partially occupied by a public organisation -Is accessible by the general public

How long is a Display Energy Certificate Valid for?

Public buildings with a total useful floor area of over 1000m2 must have their certificates renewed yearly. However, buildings between 250m2 and 1000m2 only need to have their certificates renewed every 10 years. In addition to the Display Energy Certificate, our assessor will provide an accompanying advisory report. For buildings over 1000m2 these last for seven years. Whereas for a building between 250m2 and 1000m2, the advisory report lasts for ten years.

How much do they cost?

The cost for Display Energy Certificates vary from building to building. The reason for this is that no two buildings are ever the same. Quite often public buildings can be very different in size which means some surveys can take days, whilst others only take a few hours. In order to get the most accurate quote you should contact us and speak with our expert energy team. They will be able to advise you on what is required and provide you with an exact cost.

What does the process involve?

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.  

Our assessors are fully accredited.

Public authorities must display their DEC in a prominent place clearly visible to the public, eg near the building’s entrance.

Why do I need a DEC?

What do DEC Energy Certificates Show?

DEC Energy Certificates calculate an Operational Rating (OR) for a building on a coloured graph scale. This is based on the actual energy bills of the building compared with a typical benchmark building of the same type. Each DEC has an accompanying advisory report highlighting the ways in which energy performance can be improved. Each certificate shows the current and previous two years energy rating and carbon emissions for comparison purposes. An advisory report (AR) based on a site survey accompanies the first DEC, and then is renewed every seven years thereafter (every ten years for buildings of 1000 m2 or less). The AR lists cost effective measures to improve the rating of the building. Green Zone Surveys has been providing DEC’s throughout the UK and Ireland since their introduction.

How Often do I Need a DEC and Advisory Report?

It depends on the size of your building.

  • 250m² – 1000m² – DEC and Advisory Report renewed every 10 years
  • +1,000m² – DEC renewed every year, and the Advisory Report renewed every 7 years
In Scotland, the DEC will have to be renewed annually Display Energy Certificates must be produced by an accredited Energy Assessor and be displayed at A3 size, in colour and in a prominent place near the main entrance to the building. Organisations may be liable to fixed penalty notice fines for failing to display a valid DEC or a valid Advisory Report. In Scotland, failure to renew a Display energy Certificate will automatically require you to implement your Action Plan. We can help ensure that you comply with the legislation and our in-house Project Management System prompts us to remind you when your certificate and report is due for renewal.

What does a Display Energy Certificate Involve?

Whether it’s one building, or a regional or national portfolio, Karl’s team will systematically visit and survey each building in order to produce informative Advisory Reports and accurate certificates. We can co-ordinate our visits with your building / facilities managers to ensure maximum access at minimum inconvenience, for example, visiting schools during school holidays. We’ve already helped hundreds of buildings comply with government legislation and at the same time helping them reduce energy usage and costs.

What is the difference between an EPC and a DEC?

A Display Energy Certificate (DEC) assesses the actual energy efficiency of those who manage and use the building. An EPC provides indication of the potential for energy efficiency and carbon emissions.

Why Green Zone Surveys for your Display Energy Certificate

We visit and survey every building we prepare a DEC for. Whether it’s one building, or a regional or national portfolio, Karl’s team will systematically visit and survey each building in order to produce informative Advisory Reports and accurate certificates.
