PDH, yes you need to inform the inland revenue that you are starting your own business.
If you want to be a LTD company you would have to check up at companies house to ensure the name you want use is not already being used.
If you are a sole trader you can generally use what ever name you want as their is plenty that have the same name
Thanks Robbie
