If you have the right to work in the UK, you may create your own company or operate as a self-employed freelancer. You should look into visa requirements since you may need to apply for a business visa.
According to the Office for National Statistics, 15.3 percent of the UK workforce was self-employed in 2019. This is somewhat higher than the EU average.
If you create a business in the UK under your own trading name, you may choose whether to operate as a sole trader/unincorporated firm or as a limited company. When you form a limited company, you may hire yourself as a director and have your business income taxed separately from your personal income. You will, however, be subject to extra administrative and UK tax filing obligations.
