Core revision themes

PAS 2035 process and roles

Understand how assessor, coordinator, designer, installer, and evaluator responsibilities connect across a domestic retrofit project, and where evidence moves between them.
Retrofit risk assessment and significance

Learn how risk paths are set, why moisture, ventilation, heritage, and occupant factors change the level of evidence needed, and how significance is judged.
Building physics, moisture, ventilation, and fabric-first sequencing

Revise how heat, air, and moisture interact, why fabric-first sequencing matters, and how measures can create unintended consequences if ventilation is ignored.
Measure installation and PAS 2030 compliance

Cover cavity, external, internal, loft, glazing, and draught-proofing installation, the quality checks that prove compliant workmanship, and correct handover evidence.
DEA survey workflow and EPC explanation practice

Work through safe inspection, RdSAP conventions, accurate property data, and clear explanation of ratings and recommendations before lodging an EPC.
