This is a FS251 certificate for FS Installation which will be carried out yearly. The fire contractor will inspect the entire fire service installation of your industrial building (not only your premises) and pass to FSD to obtain the certificate. Thus, if your industrial building has installed sprinkler system, FH/HR, fire shutter, detectors etc, the contractor will check all things to ensure properly.
Building management offers you a name of fire contractor because e.g. u need to relocate the sprinklers, u can call this contractor, that is. U cannot change FS facilities so as to disqualify the certificate. In other words, u can only change FS to be better.
