One number stops you in your tracks when you dig into the UK Companies House register: of the 16,677,531 companies ever incorporated in the United Kingdom, 10,742,846 have already dissolved. That’s a 64.4% failure-and-closure rate across the entire history of British commerce — a sobering baseline for anyone assessing market entry, counterparty risk, or competitive density.
At BORSCH.AI, we aggregate data across 53 UK government sources and over 50 million signals covering 5.9 million companies. What follows is drawn directly from that dataset — analysis you can’t replicate from a single Companies House download.
The State of Play: 5.2 Million Active Companies, 10.7 Million Gone
The headline figure is the sheer scale of churn. The UK register has processed 16.7 million incorporations, but only 5,241,727 companies hold active status today — roughly 31.4% of everything ever registered.
| Status | Count | Share of Total |
|---|---|---|
| Dissolved | 10,742,846 | 64.4% |
| Active | 5,241,727 | 31.4% |
| Active – Proposal to Strike Off | 545,082 | 3.3% |
| Liquidation | 119,427 | 0.7% |
| In Administration | 3,546 | <0.1% |
| Voluntary Arrangement | 543 | <0.1% |
That 545,082 figure in the “Active – Proposal to Strike Off” category deserves a second look. These are companies that are technically still live but have been flagged for removal — representing a pipeline of near-certain dissolutions. Added to the 119,427 in formal liquidation, over 664,000 nominally active entities are already in terminal decline. For due diligence analysts and credit risk teams, treating these as genuinely active counterparties is a material mistake.
Sector Breakdown: Property Dominates, Tech Punches Above Its Weight
The popular narrative paints the UK startup scene as a tech-first ecosystem. The data tells a different story.
| SIC Code | Sector | Active Companies |
|---|---|---|
| 68209 | Other letting & operating of own/leased real estate | 280,347 |
| 68100 | Buying and selling of own real estate | 255,981 |
| 70229 | Management consultancy (non-financial) | 229,353 |
| 82990 | Other business support services | 195,677 |
| 47910 | Internet retail (mail order / e-commerce) | 176,834 |
| 62020 | IT consultancy | 138,645 |
| 96090 | Other service activities | 130,064 |
| 98000 | Residents’ property management | 126,999 |
| 41100 | Development of building projects | 123,928 |
Real estate — combining letting (280,347), buying and selling (255,981), residents’ property management (126,999), and development (123,928) — accounts for 787,255 registered entities across just four SIC codes. That’s more than 15% of all active companies operating in the property sector alone.
Management and business consultancy (229,353 for the top code, plus 195,677 in broader business support services) reflects a structural feature of the UK economy: the proliferation of personal service companies and contractor vehicles, particularly post-IR35 reform. Many of these aren’t “startups” in any meaningful sense — they’re single-director consultancy vehicles.
The genuinely interesting figure is IT consultancy at 138,645. While it ranks sixth, it represents a denser, higher-revenue-per-company cohort than most property entities. For investors and platform builders targeting B2B software and services, that pool is substantial.
There’s also a notable data quality issue: 213,222 companies carry no valid SIC code (recorded as “None Suppl”). That’s a significant blind spot for any analysis relying solely on official categorisation — and one reason enriched, multi-source data matters.
Geography: London’s Dominance Is More Extreme Than You Think
London registered 1,155,104 active companies — a figure that exceeds the combined total of the next 14 largest UK cities.
| City | Active Companies |
|---|---|
| London | 1,155,104 |
| Manchester | 115,596 |
| Birmingham | 104,868 |
| Glasgow | 78,225 |
| Cardiff | 67,562 |
| Edinburgh | 61,144 |
| Bristol | 60,573 |
| Leeds | 56,786 |
| Liverpool | 51,394 |
| Nottingham | 48,425 |
| Leicester | 48,397 |
| Sheffield | 38,779 |
| Harrow | 32,087 |
| Ilford | 31,754 |
| Coventry | 31,392 |
| Next 14 cities combined | 827,982 |
London’s 1.15 million active registrations versus 827,982 for cities ranked 2–15 combined is a stark illustration of capital concentration. What’s notable further down the list is the appearance of Harrow (32,087) and Ilford (31,754) — outer London boroughs that individually outpace large English cities like Coventry. This reflects the density of SME formation in areas with high concentrations of South Asian entrepreneurial communities, a well-documented but often underweighted factor in UK economic analysis.
For fintech developers and B2B service providers, the regional breakdown suggests that any go-to-market strategy targeting “the UK” without a London-first approach is leaving the largest segment underserved.
The Digital Gap: Most UK Companies Are Invisible Online
Of the 5,280,503 companies enriched in the BORSCH.AI dataset, only a fraction carry verified digital contact data:
| Contact Type | Count | % of Enriched Companies |
|---|---|---|
| Website | 382,969 | 7.3% |
| Phone | 61,468 | 1.2% |
| 56,867 | 1.1% |
This is striking. Over 92% of UK companies have no verified website in our enriched data. Only 1 in 88 has a confirmed email address. This isn’t primarily a data collection limitation — it reflects the reality that the vast majority of UK registered companies are micro-entities, dormant vehicles, or single-director SPVs with minimal operational footprint.
For sales and marketing teams, this means that raw company count is a deeply misleading proxy for total addressable market. The genuine pool of reachable, digitally active businesses is far smaller than the headline 5.2 million active companies suggests.
For compliance officers and due diligence teams, it means that a company’s absence from digital channels isn’t inherently suspicious — but the presence of mortgages (802,299 companies carry registered charges) without any digital presence is a pattern worth scrutinising in high-value transactions.
What This Means for Your Business
If you’re in due diligence or credit risk: The 545,082 companies flagged for strike-off represent immediate exposure for anyone extending credit or entering contracts without live status verification. Static datasets go stale fast — real-time signals matter.
If you’re an investor or market researcher: The dominance of real estate and consultancy vehicles in registration data means sector-level counts dramatically overstate the number of genuine operating businesses. IT consultancy’s 138,645 is a more productive hunting ground than raw numbers suggest.
If you’re a fintech developer or B2B platform: The 7.3% website coverage rate tells you that reaching UK SMEs digitally requires data enrichment far beyond what Companies House alone provides. The gap between registered and reachable is your market opportunity.
If you’re tracking UK startup formation trends: The 10.7 million dissolved companies aren’t failure stories alone — they include millions of legitimate closures, restructurings, and dormant vehicles. Context is everything, and context requires cross-referencing multiple data sources simultaneously.
The UK company register is one of the richest commercial datasets in the world. But raw access to it, without the enrichment, cross-referencing, and signal aggregation that separates noise from insight, leaves most of its value on the table.
