Covers the RdSAP 10 changes to on-site data collection and calculation, and how they affect assessor workflows, pricing and client conversations.
This course provides a structured understanding of RdSAP 10, helping you connect the technical changes to your day-to-day retrofit work. You will learn to navigate the new data collection requirements and software updates that improve the accuracy of Energy Performance Certificates (EPCs). It also covers the real-world impacts on assessor workflows, including the need for longer site visits and updated pricing strategies.
RdSAP 10, Reduced Data Standard Assessment Procedure, Net Zero, Window Measurement, Air Pressure Testing, Ventilation Counting, Age Band M, PV Diverters, Heat Pump SPF, Seasonal Performance Factor.
This lesson covers the detailed information assessors must now collect, such as individual window measurements and specific ventilation counts. You will learn to record exact insulation thicknesses and identify modern technologies like PV diverters and battery storage that were previously undervalued. The outcome is the ability to gather precise, structured site data that ensures modern retrofit measures are properly recognised in the EPC rating.
Here, you will explore the changes "under the hood," including a redesigned calculation engine that accounts for wall thickness and seasonal performance factors for heat pumps. You will learn how new building standards, such as Age Band M for post-2023 homes and specific basement categories, affect the modelling. The outcome is the ability to interpret how the enhanced calculation engine produces more accurate baseline EPCs, particularly for complex or low-carbon homes
The final lesson addresses the operational impact of RdSAP 10, explaining why surveys may take 20 to 30 minutes longer due to increased precision. You will learn strategies to manage client expectations regarding pricing and to communicate the value of more accurate, personalised EPCs. The outcome is the ability to adapt your business practices and scheduling to accommodate the new standards while maintaining profitability and compliance.
