I may be missing something here but I just completed the HMRC Employment Status Indicator, honestly answering the questions for the Brookfield arrangement. I got this:
The worker is self employed [Why?]
Summary of outcome.
There is a low indication of substitution. [Why?]
There is a high indication of control over the worker. [Why?]
There is a high indication of financial risk. [Why?]
Has anyone else done it? Did you get a different result?
