does your phone work?
if you have done a factory reset by holding recessed button on back until lights flash and still the same then phone CS and asked for replacement
as TT, BT and all other ISPs apart from virgin use the openreach network I would expect your speed to be similar whichever ISP you choose
I use a smart hub and have since their inception and don't have any problems only people with problems post on the forum not people who want to say hub works ok
I have seen that solid light issue reported before. Try a third party router, but don`t pay too much money, as you can get one for less than £40 locally. It will prove whether it is a home hub fault, and can be kept as a spare, or returned when BT send you another home hub.
Make sure its a VDSL one, eg TP-Link TD-W9970, otherwise it will not work, as there are a lot of wireless routers that are advertised as working with fibre, but they omit to mention that you need a modem as well.
When you checked you phone line, did you make sure it was the correct phone number, as you could have a crossed line?

Yeah used phone to call mobile all is sound there. Was going to get a net gear nighthawk or equivalent Asus and use the Bt smart Hub as the back up.
The Netgear Nighthawk is only a wireless router, you cannot use it on VDSL without buying a modem as well. That is why I gave you that warning on my last post, its a very common mistake people make.
You need a VDSL/ADSL combined modem/router, not a wireless router.
As you may be entitled to a replacement home hub as @Techwizz has said, I would not be inclined to spend a lot of money, just to prove where the fault is.
I assume you are on VDSL, as you have posted on the fibre board? Your speed seems quite low for VDSL, but you may be quite a distance from the cabinet.
