Why Retrofit Skills Are in High Demand
With the UK working toward net-zero carbon emissions and homes being a key part of that challenge, demand for skilled retrofit professionals is on the rise. If you’re currently working as a Domestic Energy Assessor (DEA), now is the perfect time to explore the next step in your career: becoming a PAS 2035 Retrofit Assessor.
But what’s the difference between these two roles? And why are so many DEAs choosing to upskill? In this guide, we break down the key distinctions and explain how you can transition into this high-demand role.
What Is a Domestic Energy Assessor (DEA)?
A Domestic Energy Assessor is trained to assess the energy performance of existing residential properties and produce Energy Performance Certificates (EPCs).
DEA Responsibilities Include:
- Conducting visual inspections of domestic buildings
- Using RdSAP (Reduced Data SAP) software to calculate energy ratings
- Producing EPCs for homeowners, landlords, and estate agents
- Advising on basic energy-saving measures
While the DEA role is essential for compliance and property transactions, it offers a surface-level view of energy performance and is often the starting point for those entering the energy efficiency industry.
What Is a PAS 2035 Retrofit Assessor?
A Retrofit Assessor operates under PAS 2035, the UK government-endorsed standard for domestic retrofit projects. A PAS 2035 Retrofit Assessor builds on the skills of a DEA but goes far deeper to support the safe and effective planning of home energy improvements.
Retrofit Assessor Responsibilities Include:
- Conducting Whole Dwelling Assessments
- Collecting data on the building’s condition, significance, occupancy behaviour, and ventilation
- Identifying potential risks such as moisture or structural issues
- Feeding assessment results into the PAS 2035 Retrofit Plan, working with Retrofit Coordinators, Designers, and Installers
This role is essential for any home receiving government-backed funding for energy efficiency improvements, making it a natural progression for DEAs.
DEA vs PAS 2035 Retrofit Assessor: Key Differences
Here’s a side-by-side comparison:
| Feature | Domestic Energy Assessor (DEA) | PAS 2035 Retrofit Assessor |
|---|---|---|
| Primary Function | Produces EPCs for energy performance certification | Completes in-depth Whole Dwelling Assessments for retrofit planning |
| Regulatory Framework | EPC legislation | PAS 2035 Retrofit Standard |
| Assessment Scope | Visual inspection and data entry using RdSAP | In-depth survey covering condition, occupancy, ventilation, significance |
| Client Output | Energy Performance Certificate (EPC) | Retrofit Assessment Report for Retrofit Coordinators |
| Collaboration Level | Independent work | Works as part of a multidisciplinary retrofit team |
| Skills Required | EPC knowledge, building fabric basics | Additional knowledge of moisture risks, occupancy patterns, ventilation |
| Career Progression | Entry-level energy efficiency role | Mid-level role in the UK’s retrofit ecosystem |
Why DEAs Are Becoming Retrofit Assessors
If you’re already a certified Domestic Energy Assessor, you’re perfectly placed to upskill into retrofit. Here’s why it’s worth the leap:
- High Demand Across the UK
Local authorities, housing providers, and contractors need qualified PAS 2035 Retrofit Assessors to deliver funded retrofit projects. - Better Earning Potential
Retrofit assessments are more in-depth and typically command higher fees than EPCs. - Make a Real Impact
Help improve homes, reduce fuel poverty, and tackle climate change – one retrofit project at a time. - Natural Progression for DEAs
With your RdSAP knowledge and property survey experience, you already have the foundation.
