About 1,000 UK software companies publish a full profit-and-loss, booking £33.2bn of combined turnover between them. Software has the best unit economics of any market we’ve mapped — a true product company sells the same code many times over, so margins run far above anything in staffing, hotels or car retail. The catch is that the category is full of companies that aren’t really software at all. Figures are approximate — verify against a company’s own accounts before relying on any single number.
The “biggest” aren’t all software
The largest companies by turnover mix genuine software with impostors. Trailfinders (£990M) is a travel agent; Workwell People Solutions (£1.18bn, ~13,000 on payroll) is an umbrella-payroll group. The real software and platform giants are below them.
| Company | What it is | Turnover | PBT | Margin |
|---|---|---|---|---|
| Oracle Corporation UK | enterprise software (UK arm) | £2.35bn | £66.5M | 3% |
| Zebra Technologies Europe | devices + software | £1.22bn | £79.5M | 7% |
| Cloud SG UK | cloud services | £1.04bn | £73.2M | 7% |
| Sophos | cybersecurity software | £662M | £184.7M | 28% |
| Cirrus Logic Intl Semiconductor | chip design/IP | £563M | £248.8M | 44% |
| EPAM Systems | software engineering services | £395M | £25.9M | 7% |
Zebra and Cirrus Logic file their accounts in US dollars; figures are converted at the year’s exchange rate.
The pattern even here: the product / IP companies (Sophos at 28%, Cirrus Logic at 44%) earn multiples of the resellers and services arms (Oracle UK’s local entity at 3%, EPAM at 7%). The UK arm of a global software giant is often a low-margin sales-and-support operation; the margin lives where the intellectual property is owned.
The shape of the market
Profitability rises with scale, but the real story is the dispersion — software has both the highest-margin companies in any of our reports and a graveyard of sub-scale, loss-making product hopefuls (the sub-£5M tier is barely break-even).
Where the real software economics show up
Strip out the resellers and impostors and the genuine product companies are extraordinary: Epyx (89% margin), Travelfusion (86%), Magmatic Games (84% on 11 staff — an IP-licensing model), Veeva Systems UK (62%), The Phoenix Partnership (49%, health software), Clinisys (41%), Figma UK (36%). These are the margins that make software the most attractive business model in the dataset — revenue that scales without proportional cost.
| Company | What it is | Turnover | PBT | Margin |
|---|---|---|---|---|
| Epyx | automotive SaaS platform | £67.4M | £60.0M | 89% |
| Travelfusion | travel-tech platform | £84.9M | £72.8M | 86% |
| Blue Prism | RPA software | £78.0M | £61.3M* | 79%* |
| Veeva Systems UK | life-sciences SaaS | £62.9M | £38.8M | 62% |
| Clinisys Solutions | diagnostics software | £74.4M | £30.7M | 41% |
| Figma UK | design SaaS | £74.5M | £26.5M | 36% |
*Blue Prism’s profit is an intercompany artifact rather than organic product margin: since the SS&C acquisition its P&L is carried by a ~£62M IP recharge from its parent, and stripping that out the UK entity trades at a small loss. It stays in the table for scale, with that health warning.
Growth, read with care
The genuine momentum names combine real growth with hiring: Figma UK (+214%), DeepL UK (+176%, +118% staff) and Fintern (+147%, 31% margin) are scaling and staffing up at once — the meaningful signal. The extreme outliers above +500% are licence-recognition or restructuring artifacts, and several fast growers are still deeply loss-making (Modulr, Pineapple) — buying growth ahead of profit, the classic venture pattern.
Market structure and vintage
Software is the most fragmented market in this batch — the top 5 hold just 21% of turnover, the top 50 barely half. There is no dominant UK software incumbent; it is a deep field of mid-market product companies. The vintage profile skews recent (2010–15 the largest cohort), as you’d expect of a category that keeps producing new entrants — though, tellingly, no visible 2021+ wave at material scale yet.
What the map shows
- Software is the best business model in the data — genuine product companies run 60–90% margins, far above any other market we’ve mapped.
- But “software” is contaminated — a travel agent and an umbrella-payroll group sit near the top; read what a company actually sells.
- Product beats reseller. The UK arms of global giants (Oracle, EPAM) run thin; the margin lives where the IP is owned (Sophos, Cirrus Logic).
- It’s fragmented and venture-shaped — no incumbent, a deep mid-market, and a tail of loss-making growers buying scale ahead of profit.
Methodology and caveats
This covers only the UK software companies that publish a full profit-and-loss (most are too small to report figures); the category bundles resellers, services arms and some non-software businesses alongside genuine product companies, so read what each one sells; extreme proportional outliers are excluded from the charts. Figures are approximate and business-type labels are directional. This is analysis, not financial advice — verify any specific figure against the company’s own accounts.
