BT cannot cancel your Sky broadband, but if you are on a legacy arrangement called SMPF , where you pay line rental to BT , and pay separately for broadband, in your case with Sky , this shared metallic path facility cannot exist in an all IP world which is what is currently happening , migration to Digital Voice (and off the PSTN network which isn’t an IP system) and the PSTN switch off is part of it , presumably Sky have decided to cease your broadband because it’s on SMPF , rather than start a negotiation with you again , it’s no longer viable to maintain this type of arrangement, it’s going to have to finish sooner rather than later, Sky presumably have decided to bite the bullet and terminate your service now ……you incorrectly ‘blame’ BT for this , it is impossible for BT to issue cease orders for other companies connections.
Sky first line customer service can tell you what they want , it doesn’t make it true , Sky have decided to cease your SMPF broadband, because it has to go anyway , they offered you probably many years ago the option to join Sky for broadband and telephony but presumably you didn’t accept their offer back then.
You also seem something of an oddity in that literally decades ago , when Sky gave all their SMPF broadband customers an ultimatum, join Sky for both telephony and broadband or find another broadband provider , so somehow you slipped through the cracks most didn’t get to stay on this shared arrangement, somehow you did .
SMPF was popular decades ago , when it was required to have BT providing a phone line so they ir others then could add broadband to it ( as an add on ) that hasn’t been the case for very many years, Sky has offered its own telephony for decades , SMPF has been a legacy product on the wane since then , frankly you should have acted earlier to get off SMPF while you still had ‘control’ of the process , basically you have run out of time and Sky have decided for you .
Contact Ofcom all you want but it’s difficult to see what your complaint is , Sky not BT have arbitrarily given you notice to find a different broadband provider ,that’s their choice , you are obviously at liberty to rejoin Sky for broadband and telephony ( if you want them to add telephony to Sky broadband) but you cannot stay as SMPF , or alternatively add BT broadband to your BT telephone (once Sky have removed your SMPF broadband service )
Finally , this is really a blessing in disguise, you will have been paying in the order of double the price that having broadband and phone with a single provider would be , that’s with either BT or Sky, doing this at any point in the last 10-12 years ( joining Sky for both services or BT for both services ) would have halved your costs , by delaying , it’s been ridiculously expensive, by remaining on SMPF for as long as you have , it’s probably costed you over £3000 more than necessary over the last ten years .
It seems pretty simple the way forward , decide who you want to be with , BT , Sky or even a new provider and then arrange to join them for both services , unfortunately by leaving it as late as you have , a period without broadband is probably inevitable, acting sooner would have been preferable and avoided any broadband down time .
