Cheers Mick for the information.
I'm slightly worried about the line as it's a bit 'noisy', but I intend to remove all the old legacy extension cables dotted about the house which are not in use.
I also have an old 'GPO' silver post in the garden about a foot tall, and I'm not exactly sure what it is or even if my line is connected to it.
This may all have an impact on my speeds.
I'll really like a site survey done before I commit but, I doubt if I could arrange it

I suppose I can always cancel assuming BT give a cooling off period with the Contract.
I'll keep this thread updated as I go along.
Cheers,
