When running the Part L, EPC calculation i'm getting a error message that the C-Reg-Number is not valid.
can you please advise.
I hope that you are well.
The assessor number is the same as the CIBSE Certification Lodgement system?
I will need the assessor details to be able to lodge an EPC.
I'm well thanks, hope all's good with you too.
I'll dig into this for you - I am logging a Service Request now and will send you a project upload link.
