As stated , MDU are a different because of the complexity of providing service , so it’s entirely possible to have a MDU , surrounded by SDU ( single dwelling units , houses basically ) and the SDU can order FTTP but the MDU ( multiple dwelling unit ) cannot ….typically Openreach have code powers to provide FTTP access points in the footpath ( joint boxes or telegraph poles ) and the only permission required to deliver FTTP to a SDU ( to attach a wire or dig the excavate the front garden ) is the customer ordering services , so permission isn’t going to be a problem ,
with MDU’s it’s totally different, if it’s a modern MDU ( so all the existing copper cables were originally provided as the building was under construction) there is no easy retro fit path for fibre , plus the freeholder, managing agent etc. need to give permission, grant wayleaves etc , because the work required is in common areas ( corridors, risers , etc ) and individual residents cannot grant permission to work in theses areas , that has to be from the freeholder, building owner / management etc
Enough capacity is provided for the MDU when the general area is covered ,but the MDU is not shown as ready for service even though the neighbouring SDU are ……eventually, should permission be sought and granted, the MDU is ‘block wired’ , and the individual MDU addresses can order FTTP , but it could be years after the SDU can order FTTP , and if the building owner never grants permission, it may never be available.
