I am from the UK and started working for a UK-based company a few months ago. However, I have moved to Spain recently, got my autonomo status but wanted to continue working for my UK company whilst living in Spain.

I thought that I could become self-employed and invoice them for the hours that I do but I am worried that over 75% of my income will come from 1 company (in reality 100% will come from them) and therefore I can be classified as a "false autonomo". Therefore, I have explored the option of using an umbrella company which would employ me and then my current company would pay them directly - do you think this is a risk-free option? I just want to ensure that both I and my company are safe and compliant. What are the risks/considerations to have in mind both for me and from a company perspective?

Thanks for your help!
