If it’s a newsite property that’s never used the Openreach FTTP connection preferring until now to use Virgin , then IMHO it’s not likely that the ONT cover was fitted , by Openreach themselves or the developer using DSE ( developer self install , where the site sparky fits the ONT and OR pay the developer an extra £35 to do this ) but not the ONT as well , it’s possible someone went into the enclosure and removed the ONT , although that also seems unlikely, why leave the ONT enclosure in place but remove the ONT from within, however unplugging the ONT from the mains and throwing the power supply unit in the bin is certainly possible, if the previous occupant decided that they will never use OR , and didnt want a power outlet made unusable because the ONT PSU was connected , until the OP confirms if the ONT is present or not this is all conjecture…if the ONT is present and the ISP requires the serial number , even if the ‘sticker’ is missing on the ONT cover or the front of the ONT , the factory fitted label should still show the SN on the rear of the ONT , and as stated , if the ONT is missing then the ISP will need to arrange a new installation so a new ONT is provided and authenticated , rather than a takeover of a live but dormant service …
