When you have a MDU (multiple dwelling unit ) with a telegraph pole outside , although it’s potentially possible to feed each unit from the pole ( provided each unit has a wall /aspect that faces the pole ) it’s a much neater job ( if internal cabling isn’t really a possibility ) to provide a block on the wall , often served from the pole , that way instead of (for example) in a block of 12 units having 12 cables from the pole one to each unit looking an eyesore , you have 1 cable from the pole to a wall block , then you cable on wall (cow) from the block to each individual unit , so it’s much less visually intrusive , there may be a mix though , some units from the pole , some units from a wall block , this depends on the person who did the survey .
The survey note says
Single Dwelling Unit Residential OH External CBT Complex L2C
This indicates that this is the method for your flat within the MDU , is from an external wall block not a telegraph pole , as you are on the top floor chances are scaffolding or a hoist will be needed to get a cable from the wall block to your flat .
Virgin may not have the same set up , or they may not bother with jobs that require extra expense, like hoists , scaffolding etc , that’s not really anything that can be commented on on this BT forum you would have to take that up with them , but just because Virgin had problems doesn’t mean Openreach will , but it is a ‘complex’ installation and will need a installation survey as well as the previous network survey, Virgin don’t use Openreach network.
Its not likely in a MDU that any individual unit would be excluded , but if it were the case , there just wouldn’t be a survey note for that individual unit , so no way for an ISP to order FTTP for that unit
