Well, popped over to the house I hope to be buying this eve, and had a chat with the current owner - just go over a few finer points etc...

Turns otu he had NTL as his ISP and the spare bedroom (will be PC room) already has an NTL line installed - so all I have to do is call em up and get em to turn it on

Looks like I will go with NTL then I reckon. Which means I can junk the BT phone line that I will never use!!!!
