What this means if you’re starting one

Most of these businesses are run by one or two people

The typical plumber company in Edinburgh reports 2 employees; the top quarter has 3 or more (275 filings).

You are mostly up against owner-operators. Your own hours are likely to be your biggest cost, and the easiest one to undercount.

What 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.
