Buuultulip. Are you telling me that if a complete stranger turned up at your door and said he was the builders labourer you would let him in unquestioned?
People do. I don't think it quite works like you have posted, normally when you employ a builder for a contract that matters for the tax bill (in cash terms), it will be a large enough job for them to send two or three guys. During the course of the month or two that the job takes you could end up with a completely different three guys at the end than you did at the start.
Besides, that is just one example, there are loads of others. Actors, footballers, lawyers(not chambers) etc are all employed on a personal service basis.
These people "tick" the self employed box for a different reason.
I'm not discussing these other reasosn, I only commented upon substitution.
Further, my business is far too complex to send a sub (on many occasions). Any plumber can see what needs doing, as can any electrician or brickie. Assuming you are a programmer, could you just turn up here and start fixing the bugs in the helicopter nav system I am presently working on?
You can't. And as I have said before on this board (many times) I don't believe that we (most contractors) have a hope in hell of passing the IR35 tests using a substitution clause, and I doen't see (a) why people have put so much effeort into trying, (b) why having a court say something that ISTM ought to be blindingly obvious is a setback to the cause (other than a self inflicted one).
My point isn't about whether IR35 is right, it's about whether we could (or should) be able to get past it using substitution and I've always believed that answer to be "no", and ISTM that a lot of effort (that could have been usefully used elsewhere) has been wasted finding this out
