Course Title:

Level 3 Certificate in Domestic Energy Assessment(5 Days)

Retrofit Assessor (2 Days )

Awarding Body: City&Guilds / ABBE

This five‑day online course, delivered live via Zoom with an expert trainer, provides the skills and knowledge required to assess domestic properties and produce accurate Energy Performance Certificates (EPCs). EPCs are a legal requirement when a property is sold or rented, and they are also essential for government‑funded retrofit schemes.

Private landlords must obtain EPCs to demonstrate compliance with the Minimum Energy Efficiency Standards (MEES), currently set at a minimum rating of E.

Throughout the training, you will complete five real EPC assessments using government‑approved software, giving you practical, hands‑on experience. You will also begin building your qualification portfolio, which includes sample EPCs and academic assignments. Much of this portfolio will be completed during the five days of live training, though some tasks may need to be finished remotely afterwards.

Retrofit Assessor (RA) Training

Building on your Domestic Energy Assessor (DEA) qualification, this intensive two‑day course prepares you to carry out professional retrofit assessments for domestic properties. Retrofit Assessors conduct a detailed survey that includes:

RdSAP Data Collection

Floor plan creation
Ventilation assessment
Property condition survey
Occupancy assessment

The completed assessment is lodged in the TrustMark Data Warehouse, where it supports Retrofit Coordinators and other stakeholders in progressing retrofit projects.

You may begin your Retrofit Assessor training while finalising your DEA portfolio, but your certificate will only be issued once you have successfully achieved your DEA qualification.

By combining the DEA and Retrofit Assessor Training, you’ll be fully equipped to assess, advise, and contribute to improving energy efficiency and sustainability in UK housing. This pathway enables you to play a key role in creating greener, more energy‑efficient homes.

Lee Wells

DEA Training

“Good a detailed online course, lots to take in but spread out well as it can be overwhelming if there's too much information at once. Clear and concise instructions through zoom, glad there was a more practical case study as I learn by doing things and not so much listening. Would recommend.”

Ryan Kennedy

DEA Training

“The five day NDEA course I attended was delivered in a very professional and well-paced manner. Due to the amount of information required as part of this qualification, it was never going to be an easy task to fit all the information into a five-day period, but the salient elements of the course were provided, allowing our group to move forward in a positive manner. Muhammad our trainer was awesome, he was very knowledgeable and patient, ensuring we all progressed at the right pace and level of understanding. I would recommend this course to anyone seeking the NDEA qualification!”

Andy Hill

“Trainer Muhammad had an easy and relaxed training style. The sessions were intensive because there was a lot to cover but Muhammad was calm and helpful throughout. It was a really enjoyable experience thanks to Muhammad - it is fairly dry subject matter but Muhammad made sure it was never boring and he also ensured everyone was supported throughout. Highly recommended”
