Hi everyone, I have been working for myself for around 2 years now and I have started doing work for bathroom shower in Glasgow. It worked great at the start they supply materials and customer and I supply trades with an invoice sent on completion. It's gotten to the point where he owes me for 3 (I've already paid other trades) and there is 2 ongoing. I'm starting to hear of other subcontractors who are in the same position and are owed for a few jobs some even upwards of 20k. I'm now at the stage where I can't afford to even put fuel in my van and he won't even answer his phone so where do I stand and what can I do?
