I think if you are upgrading to Full Fibre 500 or above you should be given at minimum the EE Smart Hub Plus that has WiFi 6 capabilities not the outdated EE Smart Hub or BT Smart Hub 2.
On the plus side. FTTP installed in 1hr30 mins overhead. MJ Quinn engineer was fantastic and discussed my needs as I needed the ONT to be installed on the 1st floor as that was where my router and some ethernet cables are routed to.
Ended up getting an internal CSP as worked out better cosmetically instead of having 2 cables running up and down the walls on the outside of the house.
Using my existing BT Smart Hub 2 and complete WiFi disk so was literally 1 min to swap over from FTTC to FTTP
Very happy and blazing speeds from the off.
