Are you just curious generally to what will be involved if and when FTTP can be ordered then?
Ultimately you don’t need to worry about it too much, OR will find a way.
As far as FTTP is coming, so is Christmas
If the image is of your existing copper cable house lead , once FTTP becomes available it will be a two stage installation and the survey note on the DSL checker will probably be ‘ partial DIG ‘ , and a long lead time should be given to account for the extra time needed for this type of installation.
The existing D100 will be almost certainly be regarded as irrelevant, a new Duct 56 is needed , and will be provided from the existing joint box to the house wall , it’s only provided once an order is made ( not before ) the first stage techs may try and push the fibre up the duct D100 first before committing to digging in a new duct , but as you say the D100 is not the full distance to the house wall from the box and simply gets to the customer side of a garden wall , so that attempt will fail
I don't mind getting the Duct 56 installation, it would be more of a professional install that way with a bit of disruption to the front garden!
I have an altnet available (Hey!Broadband provided by F&W Networks) but I'm hesitant to order from them as their FTTP labour work/build quality/network topology (CGNAT) are highly unfavourable to me. I mean look at a this shabby piece of installation: Hey!Broadband FTTP Install ... absolute dire!
I doubt they will agree to only provide duct from the box to the customer side of a boundary wall and then lay the cable overground to the house wall , it would be a trip hazard and liable to be damaged , if the installation of a new duct the entire way from the box to your house wall isn’t any good for you , then that’s a problem, if there happens to be a wall or fence that the cable could be fixed to , to get from the curtilage to the house wall in a continuous run , COW ( cable on wall ) is an acceptable method of cabling so that may be an alternative if such a wall or fence exists
There is a wall where the fibre can be fixed to. So will BT/Openreach entertain that or will they be adamant about installing ducting all the way to the house wall (CSP)? TBH after thinking about it, I wouldn't mind ducting all the way to the house wall (would be way more professional and future proofed for any other future wire installation) ... temporary pain in the front garden I guess but it's not the end of the world.
I won’t ask how you have a picture of your house lead in an opened jointbox , the image isn’t particularly clear but there was for a period something called Duct 100 ( a 1 inch duct ) that was used , a bit like a rigid hose pipe and although called a duct it was more something to encase the copper cable , and as you state , it’s not really a big enough duct to get a second cable in alongside the copper one , and often the duct 100 doesn’t run the entire distance from the box to house wall , in these cases although Openreach may try to get a second cable into the D100 , it should be treated as if there were no duct at all , so a brand new duct 56 ( a 2.5 inch duct ) to the house from the box in the photo
