Inquiry: Employed or Self-Employed Tier 4 student?

Hello. I'm a Tier 4 Student and I'm aware I can't work as self-employed but have an enquiry regarding this topic.

I recently passed an interview with a company that offers health and wellness services. I am a yoga teacher and this company basically works as a platform that connects me to clients who are looking for yoga classes through their app. I am part of their team but have not yet signed any contract as an employee.

Would this be considered self-employment?

Thank you!

Sounds like it to me.

If you are responsible for your own Tax/NI then it's self-employment.
