Because the info on the checker shows SDU/MDU external CBT , complex, then unlike some apartments where there is a common internal point where all individual units would be served from your service would appear to be served from an external CBT ( pole or wall mounted most likely ) but the installer may need special tools or assistance to get the fibre into your apartment, AFAIK, you won’t get an appointment as such , but a date for a visit, if it can be done on that day , that’s great…if OR have to arrange something extra ( like long ladders , or someone who is flat roof trained etc ) then the date can slide without compensation being due ( well not to the ISP from Openreach) , it’s like the two stage install where they confirm no issues before committing to the contractual date…what the ISP does with that is between themselves and the consumer
