I have been trawling through planning applications but I can't see any relevant. In any case it's usually a developer that puts it in, builds and then the stores lease the buildings, that's how most companies I have knowledge of do it.
Think I'll have to wait and see although I will call the planning office.
This be rather a silly suggestion but most companies want you to know they are coming so advertise on bill boards and the like on the actual site long before anything is built. Something like "coming soon PC World" or whatever.
