LLC, LLP or LTD? - For a Branding Agency. (UK)

Hello,

My brother and I are setting up our branding agency in London, UK. Our next step is looking at registering our company either as an LLC, LLP or LTD. I have been reading up about these options online and I am not sure what will be best for us in the future.

In the future we hope to employ people and lease an office space. Our company doesn’t need funding from investors and so we won’t have to sell stock for capital. We sell a service to our clients, not a product.

From what I can interpret, an LLP must be started with two members (or one person and a LLC company). Which one is also more tax efficient for our situation? LLC, LLP or LTD?

Any advice is much appreciated! This choice really is a struggle.

Many thanks,
Andrewe
