Hi my fire is four years old we have just had annual bass check he smoked tested the flu all OK but glass keeps sooting up really quick not happens before help
A "sooty flame" indicates that incomplete combustion is taking place. The most likely cause for incomplete combustion is lack of oxygen.
Look to the air flow

check that the airwash vents are open, sometimes damp wood will make the glass black, put a big fire on , and text the airwash vents,
