RdSAP 9.94 is the latest version of RdSAP used for producing Energy Performance Certificates for existing dwellings from 22nd September 2019.

The update from 9.93 includes: 

  • Additional questions to be answered when creating a new EPC – The DEA should check the EPC register to see if an EPC exists for that property. If there is already a valid EPC on the register, the DEA must then select an option to explain why another EPC is being produced.

  • The ability to use Appendix Q savings in the calculation – Appendix Q is part of SAP that is used when a technology is not yet in the Product database, for example; flue gas heat recovery and heat pumps used to use Appendix Q before they were included in the Product Database. Basically, BRE produce a spreadsheet that enables the user to calculate the fuel or CO₂ savings from a new technology such as solar assisted heat pumps or dynamic insulation. The DEA can then include this saving in the data entry. As part of this addition there will be a new Addendum for the EPC to explain to the recipient that the savings from a new Technology have been included in the calculation.
