Yes you can, many examples of such on companies house. Not sure it has any meaningful benefit or drawbacks, apart from restricting you to business through a single route I guess.
The benefit for the business that I have planned, an ecommerce business with the product type in the domain, is potentially having your website address as your business name + marketplace shop name + username + logo on marketplaces like ebay & amazon.
E.g. my logo could literally be my domain name, e.g. www. widgetsdirect .com, I see that as a pretty massive advantage.
They are pretty strict about advertising your website, the only place I've been able to do it with my current little venture is in the email address in business information, which barely anybody will notice. E.g.
[email protected]
But they do stipulate that exceptions are made if a domain name is basically your trading name, and I've seen some outlets do it, just wanted confirmation that from the perspective of companies house it is permitted to use a full domain name as your company name.
The Sports Direct logo on ebay, for example, states SportsDirect.com
Just seen that their business information shows their company name as:
SportsDirect.com Retail Ltd
So admittedly I didn't need to start this thread, could have gone and answered the question myself, but I'm currently in the process of purchasing a domain on sedo for this purpose and suddenly wondered whether my plan was flawed.
