What does a DEC Assessor do?

Public buildings which have a total floor area over 250 square metres and which are frequently visited by the public are required to have a Display Energy Certificate (DEC) displayed publicly. As a trained DEC Assessor you will have the relevant knowledge to assess the energy use of buildings within the public sector (hospitals, doctors, libraries, council buildings etc), using approved Operational Rating (OR) software, to produce the required energy certificate and advisory report.

DEC assessments require work to be undertaken on site with data entry completed back at home or in the office. Assessors will collect observations about the building’s heating, lighting and ventilation systems and will use documents provided by the building owner to determine how the building is used.

The time it takes to complete a typical DEC assessment depends on the size of the building. A small public building may only take 1-2 hours, whereas a large site with multiple floors or buildings such as a hospital could potentially take up to a week. Multi-building sites will always take longer to complete, but having the facilities manager of the site on hand is always helpful and can speed up the process.

Anybody can become a DEC Assessor, but it can help to have some previous experience in Non-Domestic Energy Assessment. Those with an interest in building and construction will find this role rewarding.

Depending on your experience, a DEC Assessor can earn similar to a Non-Domestic Energy Assessor. For those who choose to work self-employed,  What they earn will depend on a number of different factors, such as the level of local competition, the frequency of assessments, as well as the size and complexity of the buildings they are assessing.

There are a few different avenues available to DEC Assessors. These include; registered referrals on our website, word of mouth, and working with local authorities.

Depending on your previous experience, and the course option you select, training will take between 1 -2 days to complete. Following completion of an assessment, you will become fully qualified as a DEC Assessor.

As the Government prepares the country for Net Zero, there will be more focus on improving all buildings – public buildings included. With this in mind, DEC Assessors will be needed to measure the efficiency of these buildings.

As a DEC Assessor, you can explore opportunities within the Energy Savings Opportunity Scheme (ESOS) and see how behavioural changes affect energy consumption in large enterprises.

In order for a DEC Assessor to produce a legally valid Display Energy Certificate, they must be accredited with a government approved energy assessment scheme- such as Elmhurst.

Accreditation schemes are there to support members in their practice, by providing them with ongoing technical guidance, training and software. They are also required to monitor the work of DEC Assessors through regular auditing- this ensures quality within the industry.

A building that is used /visited by the public and is also funded by a local authority is considered to be a public building. These include libraries, leisure centres, schools and hospitals, to name a few.
