[Mersault]

I live in the heart of London City. I come to know the nearest BT exchange is less than 1 km from my home.
I will be grateful if anyone offers useful advice getting a suitable broadband package.
I read the broadband guides available on this site and found them to be very helpful.
I would like to prefer a deal from BT or PlusNet as I have plans to setup a VoIP phone as soon as I hooked up to internet.

Could anyone plz offer some guidance?
