Every limited company needs to have a registered address (where legal documents can be served) but that's frequently not the actual trading address of the business. Business owners simply pay a registration company (or an accountancy firm, etc) to use their address, with the actual firm located at that address simply agreeing to forward any mail received to the relevant company. When, in the past, I've been delivering Yellow Pages and Phone Books, I've been to some addresses that have had many hundreds of small name plates outside stating "Registered office of XYZ Ltd, etc", despite the fact the there was simply one small office at that address. (In one case I estimated that there were over 1000 companies all registered to a single address).
Since the companies which use such services are often small, one-man businesses (or even just company names registered in the hope that a business might get off the ground eventually), it's unsurprising that many of them quickly close down.
