No7 and you at No12 may be close to each other but aren’t next door neighbours, so why chose No7 and not No.10 and No 14 ( if it’s even numbers on one side and odds on the other of your road ) , or No.11 and No.13 or No 14 if your road has odd and evens on the same side , basically why not show your next door neighbours returns rather than a house a few doors away ?
FWIW , from what you have posted you do have FTTP available anyway , but it’s ECI FTTP with speeds of 330Mb , and all these legacy ECI headends have long since been replaced but anecdotally it seems housing that was an early adopter, and had ECI FTTP fitted years ago ( so will already have an ECI ONT installed in the house) struggle to get Gb speeds even though the headend is no longer an ECI headend , whereas housing that never bothered with FTTP until now can order Gb speeds because there isn’t an existing ONT at the address.
Post the full returns for your next door neighbours and the exact checker return for your address , rather than your interpretation of it .
Lastly , the return you posted for No7 is ‘built to the curtilage’ basically this a non ducted underground area where Openreach have relatively recently excavated the footpaths to leave a ‘Toby Box’ outside each address that has now has FTTP availablity, ( the same method the cable industry used 30 years ago ) , so it’s really easy to see this , a relatively recent ‘scar’ in the footpath bearing witness to the excavation and a recently installed access point opposite the house , if other houses have this but yours doesn’t , it could be that those houses have direct access to the footpath but other houses like yours don’t , like if they were on a shared but private driveway with no way to get from the public footpath to the house wall without crossing private property , even if the house in question has access rights over this shared but not public area.
