I'm fairly new to freelancing and wanted to clarify something. I'm set up as a sole trader and work with several clients directly. I spoke to a recruitment agent who said they can get me contracts but I would have to join an umbrella company (or become a limited company).
My question is can I be a sole trader with my own clients and work under an umbrella company for contracts through the agency at the same time? Or can it only be one or the other?
