What this means if you’re starting one

You can start without much equipment

The typical bookkeeper company in London carries £1,215 of equipment and other fixed assets after depreciation, lower than 100% of UK industries.

Most of the cost of entry is time and running costs rather than kit, so a small test is cheap.

Cash is tight in this trade

At year end the typical bookkeeper company in London holds £5,360 in cash and owes £7,974; that cash figure is lower than 95% of UK industries.

Typical operators end the year holding less cash than they owe, so there is little slack if takings dip or a big bill lands early.

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.
