What this means if you’re starting one
You can start without much equipment
The typical tax adviser company in London carries £2,625 of equipment and other fixed assets after depreciation, lower than 92% of UK industries.
Most of the cost of entry is time and running costs rather than kit, so a small test is cheap.
Most of these businesses are run by one or two people
The typical tax adviser company in London reports 1 employee; the top quarter has 2 or more (423 filings).
You are mostly up against owner-operators. Your own hours are likely to be your biggest cost, and the easiest one to undercount.

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.
