What actually happens after you set up a UK Ltd (that nobody mentions)

I’ve seen a lot of people excited about setting up a UK Ltd, but not many talk about what happens right after.

Not the “how to incorporate” part that’s easy.

I mean the part where you suddenly realise:

– your address matters more than you thought
– banks don’t always behave the way you expect
– you start getting letters you don’t fully understand
– and compliance becomes very real, very quickly

I’ve noticed a pattern where most people focus 100% on setting up the company, and almost 0% on what comes next.

Curious what caught you off guard after forming your UK company?
