Field note · Getting started

Three quarters of UK businesses employ nobody at all.

Almost every article about business technology is written as though the reader has a department. The official count says three quarters of UK businesses have no employees at all, and that single fact invalidates most of the advice those readers are given.

The short answer

At the start of 2025 there were 5.7 million UK private sector businesses. 4.3 million — 75% — had no employees beyond the owner. 5.64 million were small (0 to 49 employees), 38,435 medium (50 to 249) and 8,335 large (250 or more). SMEs accounted for 60% of employment and 51% of turnover, with large businesses taking 40% and 49%.

The bottom two bars are drawn to the same scale as the top one.Department for Business and Trade, business population estimates 2025.

The medium and large bars are drawn against the same scale as the first and they are barely a line. Between them they are 46,770 businesses out of 5.7 million — about eight in a thousand.

Why this makes most advice wrong

Business technology writing is produced by companies selling to the 46,770, because that is where the budgets are. The advice then circulates to the 5.7 million, who read it as though it were addressed to them.

Three assumptions travel with it and none survives contact with a firm of four.

That somebody will own the project. In a business with no employees, the owner is the project owner, the user, the supervisor and the person doing the actual work being automated.

That a pilot is cheap. A pilot in a large firm is a team's month. In a firm of four it is the owner not doing the thing that earns money.

That the saving compounds. Saving an hour a week across two hundred people is a headcount. Saving an hour a week for one person is an hour.

Eight businesses in a thousand employ fifty people or more. Almost everything written about business software is written for those eight.

What the turnover figures add

SMEs account for 60% of employment but only 51% of turnover, so the large businesses are more turnover-dense per head: about £241,000 of turnover for each person they employ, against about £166,000 in SMEs, on our division of the published totals. That has one useful consequence: the tooling built for large firms is priced against their revenue per employee, not yours.

A per-seat price set against £241,000 a head lands differently at £166,000, and this is the arithmetic behind the £200 floor — adoption costs are roughly fixed while the benefit scales with size, so the floor bites hardest at the bottom of this distribution, where three quarters of businesses are.

What this does not tell you

The figures are as at the start of 2025, published in October 2025; the next edition is due this autumn, and the population moves. They also count businesses rather than activity: a business with no employees can be a full-time practice or a side income, and the count treats them the same, so "three quarters of businesses have no employees" is not "three quarters of economic activity happens alone".

And size is a poor proxy for sophistication. A two-person firm can run better systems than a two-hundred-person one, and frequently does, because there is nobody to negotiate with.

What the distribution does settle is who the default reader should be. On this site that is a firm of between two and fifty people, which is why the triage tool says no more often than yes and why the adoption calculator will tell you a free tool can still lose money. The related arguments are in software that sells and the ONS adoption figures.

Questions people actually ask

How many businesses are there in the UK?

There were 5.7 million private sector businesses at the start of 2025, of which 4.3 million — 75% — had no employees beyond the owner. 5.64 million were small with 0 to 49 employees, 38,435 were medium with 50 to 249, and 8,335 were large with 250 or more.

What share of employment do small businesses account for?

SMEs accounted for 16.9 million jobs, 60% of the total, and £2.8 trillion of turnover, 51%, at the start of 2025. Large businesses accounted for 11.2 million jobs, 40%, and £2.7 trillion, 49% — so large firms turn over more per person employed.

Why does the business size distribution matter for software?

Because tooling built for large firms is priced against their revenue per employee rather than yours, and because the assumptions behind most advice — a project owner, a cheap pilot, a saving that compounds across headcount — do not hold in a business where the owner is also the user and the supervisor.

Does having no employees mean a business is not serious?

No, and the figure should not be read that way. A business with no employees can be a full-time practice or a side income, and the count treats both the same — so the share of businesses with no employees is not the share of economic activity conducted alone.

If you employ nobody, most of the advice you have read was not for you.

We work with firms of two to fifty, which means the first answer is usually that the thing being sold to you assumes a department you do not have. Tell us the job and we will tell you whether it is worth changing at your size — and it often is not.
