The investigation took 2.5 years and I am pleased to say that I won with PCG's help! This was 10 years ago.
I am now thinking of re-joining the contract market and wonder if I should once again go down the limited company route or choose an umbrella company.
I get the feeling that IR35 is tighter than it was a decade ago and maybe using an umbrella company will ensure I maximise my revenue retention with least effort on my part.
