When carrying out Domestic Energy Assessments, having the right equipment is essential. It makes inspections faster, safer, and ensures measurements are accurate.

Over the years, I’ve developed a toolkit covering every situation a DEA encounters — from awkward roof rooms to managing paperwork efficiently.

I also offer one-to-one DEA mentoring, providing guidance on using your tools efficiently, handling assessments professionally, and streamlining workflows for both new and experienced assessors. You can download our DEA Handbook, it covers the basics about how to set up a successful DEA business. Ready to learn all of the skills you need to become a successful business owner, book your place on our next DEA Launchpad course here. 

1. Plan Before You Step Inside – Review floor plans and plan your measurement route.
2. Use the Right Tool for the Right Job – Laser for open rooms; folding ruler or tape for wall and insulation thickness.
3. Complete each room in full before moving on. Take all measurements first, then record details of heating systems, lighting, windows, and insulation in the same room. This ensures nothing is missed and reduces the risk of backtracking.
4. Keep PPE Accessible – Dust mask, bump cap, and torch ready before entering lofts.
5. Protect Client Property – Use overshoes to keep floors and carpets clean.
6. Record as You Go – Enter data on your iPad or tablet while on-site.
7. Maintain DEA Equipment Regularly – Check ladders, clean lenses, and store tools properly.

Mentoring Tip: One-to-one DEA mentoring can help you optimise workflow, making inspections faster, safer, and more accurate.

Over thousands of assessments, I’ve developed a routine that keeps every job consistent and efficient. Preparation is always the first step — using resources like Rightmove, the Valuation Office Agency, FENSA and other tools means I walk into a property already familiar with its layout and features. (Watch my YouTube videos on how I prepare for assessments).

On site, I start outside and then work methodically through each room, following the same sequence each time. This approach ensures that nothing is missed, and every detail — from measurements to heating systems, windows, and insulation — is recorded in a logical order.

As a trainer and mentor, I’ve refined these methods further by teaching them to others. Mentoring forces you to think critically about the “why” as well as the “how,” which has made my process even more robust. For newly qualified DEAs, this structure can feel like a lifeline, you can read more in our free to download DEA Handbook. With the right guidance, you quickly turn these steps into second nature, giving you the confidence to walk into any property knowing exactly what to do, in what order, and why. My mentees often say that adopting this system, along with using the correct DEA Equipment, was the turning point from feeling overwhelmed to working with real confidence and efficiency.
