Hi there did you say you have a Fibre Cabinet next to your ordinary cabinet?
If you do try either inputting your landline number here: http://www.dslchecker.bt.com/
or use the address checker.
If you CAN get Fibre from some suppliers it will give you a speed estimate for FTTC or FTTP.
If it shows no details for FTTC/FTTP then you may have to wait for others on here to dig a bit more.
My exchange is Fibre Enabled but as yet we cannot get FTTC as no Fibre Cabinet is in place for us!
