If necessary, the Inquiry's experts will serve supplemental reports in advance of their oral evidence, to the extent that the evidence they have heard or read affects their written opinions.  They may also provide updating evidence when they come to give oral evidence in October and the reports will be treated as provisional until that point.

Please note that in her report Dr. Lane states that the fire doors in Grenfell Tower were supplied by Manse Masterdor Limited, but she also uses "Masterdor" as a shorthand reference to Manse Masterdor Limited.  Please note when Dr. Lane refers to "Masterdor" she is referring to Manse Masterdor Limited and not Masterdor Limited.
