Day in the life of a DEA
Have you wondered what life as a Domestic Energy Assessor entails? The following video explains what a DEA does, what a typical assessment involves, and how you can become a DEA.
Why choose Elmhurst for DEA Training?

Elmhurst’s DEA courses have been developed to provide information at a pace that suits all of our trainees, regardless of whether they are new to the industry or are more experienced. We ensure that everyone understands the content and are able to gradually build up their skills and knowledge.

Why become a Domestic Energy Assessor?
The role of the DEA is predominantly site based and involves the collection of domestic property data (information about Property age, walls, floors roofs etc). DEAs enter this property data into approved Reduced data Standard Assessment Procedure (RdSAP) software which calculates the energy performance of that property and produces an EPC. Assessors can either undertake this calculation on a computer following the assessment or they can speed up the process by using mobile RdSAP software to complete their assessment while on site.
An Ideal new career / new competency No previous experience or qualifications are required for individuals to qualify as a DEA, which makes starting a new career in this area relatively easy. DEAs can choose to work for an existing company or become self-employed, where they can manage their own workloads. Property Agents, surveyors and tradespeople who regularly work within residential properties will also benefit from adding the domestic EPC to their list of services.
The role of the Energy Assessor is becoming increasingly popular as the UK government aims to improve the energy efficiency of existing homes in pursuit of its net zero carbon by 2050 target.

Regulations such as Minimum Energy Efficiency Standards (MEES) in the private rental sector has also increased the demand for the services of Domestic Energy Assessors in England and Wales as landlords and property agents take action to determine if their properties are up to scratch.
Elmhurst anticipates that the UK will see more regulations come into force in the near future which will aim to increase the energy performance of people’s homes .The reference point for this is likely to be the energy rating provided on the EPC.
