You can start without much equipment

Check my ideaWhat these figures can’t tell you
Companies are counted where their registered office is, which may be an accountant or a home address rather than a shop. Sole traders and partnerships are not on the register, and electronically filed accounts cover roughly 60–75% of accounts filed each year. The figures describe companies that exist; they cannot prove demand for your idea or predict whether it will work. How the figures are built.
