To clarify further , is your business ‘fibre’ completely separate and is a fibre Ethernet leased line using its own fibre cable from outside , and has nothing to do with native GEA FTTP or copper pairs , or does it share the same copper pair as your current telephone service or was a regular FTTP connection so you have an ONT, the fact it’s supplied on a business tariff is unimportant as far as technology is concerned, do you have something like this ,
https://www.openreach.com/help-and-support/openreach-equipment-in-my-home, but rather than take telephone with that you took the very expensive option to keep a separate copper telephone line as well , ?
If your broadband is shared metallic path facility (SMPF) or FTTP , ( so isn’t a fibre leased line ) , then you do need to make a choice , and your relative’s situation is not remotely the same , anyone with a standard copper pair telephone line as their only service ( not SMPF ) will be moved to PDPL , seemingly called home phone standard by BT , this is an action taken in the exchange, relatively benign to the user (no broadband needed , no local power concerns etc ) simply the need to start to dial the full nation number on local calls ) , the notification you got suggests this isn’t you as that simply gives a date to expect a short break in service while the migration is made from PSTN to PDPL in the exchange building , many areas have had to use full nation numbers for years so even that may not be a change but a continuation of the existing situation,
anyone in an Openreach FTTP area wanting BT telephony as their only service into the address , uses the Openreach FTTP network with a ‘free’ BT broadband service to host it , they don’t get a second FTTP service if they already have a OR FTTP service from someone else , after all they can hardly claim to be unconnected, and they can add telephone from the same supplier or a VoIP supplier to that broadband if telephony is needed , to argue anything else is simply trying to game the system .
If you are SMPF , you either drop broadband , or drop telephone but you can’t remain with two separate suppliers on a single copper line , a further complicated could be if when you took your SMPF broadband you took it on a residential telephone line .
If you already have FTTP , albeit with a business, then OR/BT may be under no obligation to keep you connected with a second voice only service especially as that is a legacy PSTN product, you can elect to take telephone from your FTTP supplier or change supplier to one that does offer voice with FTTP or even use a third party VoIP supplier .
You calling regular customer service on what is today a very rare , legacy arrangement, will not necessarily get you consistent, accurate information, but the letter you got should be accurate , this forum can only give an opinion anyway ( only being a customer to customer forum) but without confirmation on what your broadband service actually is , then it’s speculative at best …..you should know if your broadband is a leased line as the equipment supplied is designed to fit in a server room rack and is clearly not a domestic piece of kit , here’s what leased line kit looks like ,

it’s also multiple times the cost of domestic broadband or FTTP , so if you are paying less than £100 a month and we’re not tied to a 5 year deal , it’s very unlikely you have a fibre leased line and you have domestic grade broadband even if it were sold to you as a business connection,
