ACI Reports has a team of accredited energy assessors delivering accurate Display Energy Certificate (DEC) reporting across the UK, including Scotland where industry standards differ.

Clients are supported in achieving legal compliance and improving the energy efficiency of their public sector buildings.

When are Display Energy Certificates (DEC) required?

EPCs measure the energy efficiency of a building based on energy performance-related features such as insulation, windows, heating, lighting, and ventilation. Contrarily, Display Energy Certificates (DECs) measure the energy usage of a building based on annual consumption.

An EPC is valid for 10 years, whereas a DEC may only be valid for one.
Like an EPC, buildings are rated on a scale from A (most efficient) to G (least efficient) and must be accompanied by a Recommendation Report outlining methods to further reduce energy consumption. Display Energy Certificates are legally required for buildings frequently visited by the public, with a total operational floor area of over 250 square metres.

What to Expect from a DEC Assessment

All our accredited energy assessors will act impartially, delivering reliable and trusted reporting to ensure legal compliance for our clients. First, we will gather data from the meter readings for all fuels used over the last year to understand the energy consumption of the building. Then we can produce the DEC and Recommendation Report by:

  • Reviewing the energy consumption data per the government-approved method
  • Making adjustments for occupancy, unique energy use cases, weather & climate
  • Measuring carbon dioxide (CO2) emissions for the operational floor area & building type
  • Reviewing measures for heating, cooling, insulation & lighting within the building
  • Assessing on-site energy generation (e.g., renewables or carbon neutral methods)

The DEC will then be submitted to the national register. The report should also be displayed in a highly visible place within the building to inform the visitors about its energy usage.

Frequently Asked Questions

What is a DEC and why do you need one?

Display energy certificates were initially introduced to improve the energy performance of commercial buildings across the UK. They measure the overall energy consumption of the building over the past year. The DEC is a legal requirement enforced by Trading Standards Officers and the ratings must be visible to visitors within the building.

How long is a DEC valid for?

Display energy certificates are valid for 1 year if the building has a total operational floor area of more than 1,000 square metres. For buildings with a total operational floor area of 250 square metres to 1,000 square metres, the DEC will be valid for 10 years.

If your DEC is out of date, ACI Reports can pick up from where the expiry left off, but only if we are instructed within 3 months. Provided we get the new report in place quickly, you are unlikely to receive a penalty.

What are the penalties for not having a DEC?

If your building does not display a valid DEC in a clearly visible place to the public, your local authority may issue a penalty charge notice of £500. If your building does not possess a valid DEC at all, they may issue a penalty charge notice of £1,000.

Who is responsible for a DEC?

It is the responsibility of the occupier (the organisation renting / using the space) to arrange a valid DEC. This is because the use of a commercial building is usually dictated by the occupier, rather than the owner.
