Is it illegal (in the UK) to put on your own website a list of businesses without their prior approval?
I want to form a list of names of businesses based on various categories but I'm wondering before I do if BobBuildingConstruuction Ltd could sue me if they don't want their name listed with other construction firms. I can't see why they'd have an issue as it would just be free advertisement. Website is harmless so there isn't anything to taint their reputations.
Also is it illegal to put with their name, an image of their business, phone numbers etc?
