Description

The ABBE Level 3 Certificate for Retrofit Assessors qualification has been developed to enable those working in the construction and built environment sector to take a qualification which covers the PAS 2035 Retrofit Assessor role. The qualification will meet regulatory requirements and will use the Accreditation Schemes to produce the reports.

This course is designed to give you the skills and knowledge to carry out PAS 2035-compliant retrofit assessments, which provide the foundation for all retrofit projects. You’ll collect and analyse property data, assess building condition and occupancy, and prepare reports that Retrofit Coordinators and Retrofit Designers use to plan effective, safe retrofit measures.

With demand for qualified Retrofit Assessors rapidly growing, this is the perfect time to gain a nationally recognised qualification and build your career in the retrofit sector.

‍

Course Schedule

The ABBE Level 3 Certificate for Retrofit Assessors is delivered online through our interactive Learning Management System (LMS).

Flexible study – learn at your own pace, with the ability to pause and pick up where you left off.
One-year access – you'll have up to 12 months to complete the course. However, if you are utilising the WHSP funding, you will have four weeks to complete the course.
Tutor support – expert trainers are on hand to guide you through your learning journey.

This format makes it easy to fit your study around work, family, and other commitments.

‍

Prerequisites

To enrol on this course, you must already be a qualified Domestic Energy Assessor (DEA), or be working towards your DEA qualification (evidence will be required). This is a requirement because the Retrofit Assessor role builds on the core knowledge and skills of energy assessment, particularly the use of RdSAP data and property surveying.

If you’re not yet a DEA, you can complete both qualifications together through our DEA + Retrofit Assessor combined training package.

‍

What's Included?

When you enrol, you'll get access to a complete learning package designed to give you practical skills and confidence:

A virtual property environment where you can practise data collection and assessment techniques.
Example retrofit documentation so you can see exactly how reports are structured in real projects.
Access to guidance, resources, and case studies covering condition surveys, ventilation assessments, occupancy analysis, and more.
Ongoing tutor support to help you with questions and feedback as you progress.
Final assessment and certification upon successful completion.

You will gain vital skills required to take on any project under PAS 2035, including:

Full competence in surveying buildings, conducting RdSAP data collection, detailed floor planning, occupancy and ventilation assessments, and condition surveys.
Eligibility to accredit with ecmk and TrustMark, enabling entry into the TrustMark Data Warehouse.
