An insight into the qualification

The DEC training qualification is comprised of a mix of classroom and distance learning elements.

We also ensure that trainees have complied with each of the elements of the national occupation standards (NOS) for display energy certificates.

The classroom element of the training course lasts one day, and takes place at our head offices in Bath.

The one day’s DEC training course focuses solely on the legislation behind DECs and the software used for producing them, building on top of the building construction and services knowledge already gained through completion of the NDEA L3 qualification.

Once candidates have completed the classroom training day, there is one assessment criterion that will need to be completed:

  • Complete a portfolio of 3 DECs on a range of non domestic properties.

Once candidates have completed the portfolio, they will be awarded the DEC qualification and WILL be ready to practice as an accredited public building energy assessor.


Getting started

For further information on the qualification please download the official ABBE handbook and the Quidos DEC level 3 information sheet from the resources tab on the right hand side.


DEC requirements

Since October 1st 2008, all public buildings with a floor area greater than 1,000m2 have been required to display a certificate detailing the energy efficiency of the building based upon the actual amount of metered energy used by the building over the previous 12 months.

DECs are required to be renewed each year, with an additional advisory report created every seven years which outlines potential energy saving recommendations that can be implemented by the building managers.

Quidos member reviews

I am impressed by Quidos who have a big presence in the market place but are a relatively small, professional and friendly outfit benefiting from good leadership. M. Simpson

This is my first experience of Quidos, and my first impression is that they are friendly and professional. J. Solti

I have had access to other ABs, and it’s my opinion that if all of them were like Quidos, the wheat would quickly separate from the chaff as far as the quality of some DEAs are, and we could charge a respectable price for an EPC. A. Rees 

I switched accreditation schemes to join quidos due to its ethical stance on quality standards within our industry. I have always found them approachable and willing to listen from the admin assistant to the managing director. Bish Shaha
