18.08.2025

Are you considering a career in the green energy sector? Becoming a Domestic Energy Assessor (DEA) and Retrofit Assessor (RA) is one of the most effective routes into this growing industry.

With the UK committed to achieving net zero carbon emissions by 2050, the demand for qualified assessors is higher than ever. Every property that is sold, rented, or retrofitted requires either an Energy Performance Certificate (EPC) or a retrofit assessment under PAS 2035. The DEA and Retrofit Assessor training course provides the essential skills and qualifications to meet this demand.


What is a Domestic Energy Assessor (DEA)?

A Domestic Energy Assessor is responsible for:

  • Inspecting homes and gathering data on heating systems, insulation, and energy use.

  • Producing official Energy Performance Certificates (EPCs) using RdSAP software.

  • Advising homeowners and landlords on energy efficiency improvements.

This role suits individuals seeking flexible work opportunities, either as self-employed assessors or as part of an organisation.

For those researching “How to become a Domestic Energy Assessor UK” or “EPC assessor training”, this course provides the recognised qualification needed to start.


What is a Retrofit Assessor (RA)?

A Retrofit Assessor builds on the skills of a DEA to deliver assessments that support the government’s retrofit programme. Retrofit Assessors:

  • Work in line with PAS 2035 standards to assess homes for energy efficiency upgrades.

  • Conduct condition surveys, occupancy assessments, and energy use profiling.

  • Produce reports that guide Retrofit Coordinators and installers.

With significant investment being directed towards retrofitting UK homes, Retrofit Assessors are in particularly high demand. This pathway is ideal for those searching for “Retrofit Assessor course UK” or “PAS 2035 training”.
