A MoneyBox programme on BBC Radio 4 last Saturday https://www.bbc.co.uk/programmes/m000tcl7 included mention of an umbrella company, said to be accredited by The Freelancer & Contractor Services Association (FCSA), which was withholding pay from contractors. The programme included commentary from Dave Chaplin, CEO of ContractorCalculator and has resulted in further comment from Chaplin as well as the FCSA itself.
