Can I find out if my neighbour actually has internet/broadband, if I know his address, telephone number and post code. He says he doesn't but I don't believe him:rolleyes:

What are you going to gain if you find this out? Knowing his address and phone number is not going to get you information on if he has internet/broadband. That is still considered private information. If he does have it and he tells you he does not have it, maybe he does not want you to know.

In the UK what you neighbour does in privacy of their own home is NONE of your business.
If they want to tell you if they have BB it's completely up to them!!

What do you hope to gain from this information anyway ?
