You need to check if there is a "Swept Tee" outside your property.

This will be evident by either a small round black plastic cap or a small box (similar to the one for a stop cock) in the ground.

If you cannot find evidence of either of these your property is not serviceable at present.

You could always ask for a local representative to attend and show you why they cannot install your broadband.

Also, if the cable will need to cross the shop property, as in up the wall, they will need permission from the owner before they will consider an install.
