Hi Janvier. The U.K will be very lucky to have you. Where are you moving to? I may be able to help and be your local guide.So, to set up your official business, you need to register for tax, and get a UTR (unique tax reference) number. I am registered as a sole trader and I trade under my name Chrysilla Lewies. It is that simple.

I’m insured with a company called Balens – https://www.balens.co.uk/
