RdSAP Online Software

Our Reduced data Standard Assessment Procedure (RdSAP) is a FREE professional software for Elmhurst Energy accredited Domestic Energy Assessors (DEAs).

The online software allows you to carry out calculations on existing dwellings and produce an Energy Performance Certificate (EPC) derived from the Government's national calculation methodology.

Using RdSAP Online

Elmhurst's RdSAP Online software can be accessed through Elmhurst's members area, and is available to all Elmhurst accredited DEAs. You can enter energy assessment data, and upload evidence to RdSAP Online in order to complete your domestic energy assessments.

The software will allow you to enter assessment data for an existing residential dwelling for a standardised RdSAP calculation, EPC rating and Energy Performance Report (EPR). You can also use the software to lodge an energy Performance Certificate (EPC) to one of the central registers.

This is a Government requirement for all energy assessor accreditation schemes. For more information about the Landmark Central Register for England, Wales and Northern Ireland click here
