Looking at the current BT new customer offers note that all are listed as "Full Fibre", is this actually the case, ie., FTTP?
The fact that "BB only no landline" is quoted would indicate that this is FTTP service.
When I migrated to BT FTTP in March this year, the basic full fibre package was "Full Fibre 100", 150/30 service, below that everything was FTTC, 80/20 or 40/10, not sure if ADSL2+ was still an option then.
Now their "Full Fibre Essential", 36/10, "Full Fibre 1", 50/10 and Full Fibre 2, 74/20 services are listed, question being are these actually FTTP or still FTTC, the quoted DL speed figures versus guaranteed DL speed figures quoted are more to FTTC loss expectations although there is also a sizeable quoted/guaranteed DL speed variation with their FF100, 500 & 900 packages.
I assume that BT are still offering (up to) 80/20, 40/10 FTTC service to new customers who don't have FTTP availability?
