Boiler Compliance Certificate

Happy_monday_2

Hi all,
I am hoping to move house very soon and the solicitors representing the buyer have asked me to provide the gas compliance certificate for the combi boiler that was fitted around 2007.
I have reserached and read other threads here about this but my query is....i wasn't supplied with the certificate and .....i have contacted the corgi installer and he has told me that he cannot now apply for the certificate, as it was 2007, BUT he could come around and inspect the gas system, including the boiler that he fitted and issue a gas safety certificate. He says that this will be sufficient and is effectively the same as the compliance certificate that should have been issued.

Does anyone know for sure if these are one and the same and will be acceptable please.
