The amount of turnover would be relevant, the commercial client base you have, we can't presume that because you have only just started you don't have some nice contracts.
From my perspective being Limited adds a certain amount of credibility and the clients I work with like to work with other VAT registered & limited companies we are turning over a small profit and am sure at some point, last November, my accountant explained the reasoning why we went limited but it is lost in the fog of my brain.
It has clear benefits but I leave all that to my accountant - accountancy bills definitely go up when you go limited, my accountant lives in a very nice house
If you are just tootling along don't stress yourself too much, just yet, with being limited, build your revenue & business first
All the best
