As stated ( and you already know ) DV works on FTTC as well as FTTP , FWIW it also works with ADSL , but the fact is once FTTP is available, it becomes the default ( preferred ) network for Openreach , so their ISP customers like BT are incentivised to get customers onto FTTP and off copper ( it’s an unnecessary cost to run both the new FTTP and legacy copper networks simultaneously ) , if you look to renew with your provider , or change provider , the opportunity to shift you onto FTTP should be taken , if your preference isn’t to take FTTP ( for whatever reason you may have ) you can ( for now ) remain on your existing ‘deal’ on an ‘out of contract’ basis, but this probably will cost you more ££’s , than being within a minimum term and getting a discount for that , that’s your choice , pay more stick with copper , pay less , move to FTTP , it’s perfectly reasonable ( in my view ) not to offer you both a ‘deal’ and the option to stay on copper when FTTP is available.
As far as ‘forced’ migration to FTTP , that won’t happen , but what may happen , maybe in 5+ years or more is you will be asked to change to FTTP or simply have your copper pair service terminated ( switched off ), but perhaps many years of paying more than necessary may persuade you to voluntarily change , some people are getting communications asking them to call to arrange FTTP installation, implying that is compulsory, but it isn’t , if the person doesn’t call and arrange a date , nothing currently happens.
The only ‘unfair’ situation I foresee, is if a tenant of a private landlord is denied moving to FTTP , not because the tenant doesn’t want it , but because the landlord doesn’t want and new work on their property, and says to the tenant that you are not allowed to upgrade to FTTP .
