As stated you providing a fibre cable that OR need to adopt and then be responsible for isn’t going to happen, as far as a tech entering your loft space , it’s better to assume they won’t and be pleasantly surprised if they will, rather than expecting them to , and being disappointed when they won’t , your existing setup was provided when rules were much less safety minded , on a repair , OR have to contend with what exists even if potentially it’s not currently complaint , new work has to follows the current rules .
If the prospect of any cable running down the wall is completely unacceptable, it may be something of a waste of time , both your own and Openreach’s ,ordering FTTP , obviously without knowing your exact setup but if you do order , I’d be assuming as being unavoidable, a single cable running down down the wall to a ground floor location for the CSP ( assuming the tech hasn’t got an internal CSP or wouldn’t enter the loft anyway ) , and you being OK with the ONT fitted somewhere on the ground floor , to a certain extent this can be where you want it , within the time / practicality restraints , and you provide your own Ethernet connection to where you want the router to be sited .
Its always possible that a tech turns up , is happy to enter your loft space and will provide exactly what you require, it’s just not guaranteed, and you would have no valid reason to complain if your request were refused , it’s a somewhat surprising comment, that you consider it a a lottery if the tech that turns up is ‘willing’ , you appreciate that’s you mean they are willing to break rules to accommodate you , if a tech injured themselves entering or working in the loft space that they shouldn’t be in , it could lead to the end that of that techs employment, ( if directly employed by Openreach ) , in those circumstances would you do it ?
