What this means if you’re starting one

London has fewer of these businesses than most places

Electrician companies are 0.43% of companies registered in London, against 1% UK-wide (0.4× the national share).

That could be a gap or a sign of weak demand. The register cannot tell which.

Most of these businesses are run by one or two people

The typical electrician company in London reports 1 employee; the top quarter has 2 or more (2,391 filings).

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

Cash is tight in this trade

At year end the typical electrician company in London holds £8,401 in cash and owes £14,362; that cash figure is lower than 60% 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.
