More than half a million UK companies — 545,082 to be precise — are currently flagged as “Active - Proposal to Strike Off.” That’s roughly one in every 10.8 registered companies in the country. For due diligence analysts and investors, this isn’t a footnote: it’s a flashing red light embedded in the UK’s corporate registry.
BORSCH.AI aggregates 50 million+ signals across 53 UK government sources covering 5.9 million companies. When you analyse accounts filing behaviour at this scale, the compliance picture that emerges is far more troubling than official summaries suggest.
The Scale of the Problem
Companies House requires all limited companies to file annual accounts and a confirmation statement. Miss these deadlines and the consequences escalate quickly: automatic penalties, credit rating damage, and ultimately dissolution.
Here’s what the current registry data shows:
| Status | Company Count | % of Total |
|---|---|---|
| Active | 5,233,040 | 88.6% |
| Active – Proposal to Strike Off | 545,082 | 9.2% |
| Liquidation | 119,425 | 2.0% |
| In Administration | 3,546 | 0.06% |
| Voluntary Arrangement | 543 | <0.01% |
| Receivership / Admin Receiver | 287 | <0.01% |
The “Active – Proposal to Strike Off” category is particularly revealing. It typically indicates a company has failed to meet its statutory filing obligations — most commonly the confirmation statement or annual accounts — and Companies House has issued a notice of intention to dissolve it. With 545,082 companies in this state, that represents a non-trivial risk for anyone relying on company status alone to assess counterparty health.
XBRL Accounts: Who’s Actually Filing Machine-Readable Data?
Beyond simple status, the depth of filing compliance matters. Companies House accepts accounts in XBRL (eXtensible Business Reporting Language) format, which enables structured, machine-readable financial data. BORSCH.AI has ingested 6,074,386 XBRL account signals, matched to 1,607,736 distinct companies.
That means just 30.7% of active companies have machine-readable accounts on record — leaving the majority of the UK corporate landscape operating in a data opacity zone.
| Metric | Count |
|---|---|
| Total active companies | 5,233,040 |
| Companies with XBRL accounts matched | 1,607,736 |
| Coverage rate | 30.7% |
| Active companies without XBRL accounts | ~3,625,304 |
This gap has direct implications for credit risk modelling, supplier due diligence, and automated financial analysis. If a business you’re evaluating sits in that 69.3% without machine-readable accounts, you’re working with less structured data — and potentially missing early warning indicators of financial distress.
Sector Spotlight: Which Industries Have the Biggest Compliance Exposure?
Cross-referencing company counts against SIC codes reveals where filing compliance risk is most concentrated. The UK’s top sectors by registered company volume are dominated by real estate, consultancy, and e-commerce — sectors with high proportions of micro-entities and sole-director companies that are statistically more likely to miss filing deadlines.
| SIC Code | Sector Description | Registered Companies |
|---|---|---|
| 68209 | Letting & operating of own/leased real estate | 279,711 |
| 68100 | Buying and selling of own real estate | 255,277 |
| 70229 | Management consultancy (non-financial) | 228,516 |
| None Supplied | No SIC code registered | 213,222 |
| 82990 | Other business support services n.e.c. | 194,777 |
| 47910 | Internet & mail order retail | 176,071 |
| 62020 | IT consultancy | 138,301 |
| 96090 | Other service activities n.e.c. | 129,515 |
| 98000 | Residents property management | 126,888 |
| 41100 | Development of building projects | 123,494 |
Two findings jump out immediately.
First: Real estate is the single largest sector, with over 534,000 companies across the two main letting/selling SIC codes combined. Property SPVs (special purpose vehicles) — set up to hold a single asset and often managed by non-professional directors — are a known weak spot for filing compliance. With 802,299 companies holding registered mortgages in our dataset, the overlap between leveraged property vehicles and potential filing failures deserves serious attention from lenders and surveyors.
Second: 213,222 companies have no SIC code registered at all — making them nearly invisible to any sector-based compliance screening. That’s a larger population than the registered company base in Birmingham (104,868). These “unclassified” entities cannot be filtered by industry risk profile, creating a blind spot for automated screening tools that rely on sector categorisation.
The Mortgages Signal: A Compliance Proxy
One underused compliance indicator is the mortgage register. Companies with active charges (mortgages and liens) tend to have stronger filing compliance — lenders typically require it as a covenant condition. BORSCH.AI tracks 2,493,063 mortgage signals matched to 802,299 companies.
That leaves over 4.4 million active companies with no registered charges — meaning there’s no lender covenant providing an external forcing function for timely filing. In the absence of bank covenants or investor oversight, filing discipline relies entirely on director awareness and, where applicable, accountant reminders.
For counterparty risk teams: a company with no charges, no XBRL accounts, and an “Active – Proposal to Strike Off” status is displaying three compounding compliance risk signals simultaneously. BORSCH.AI’s signal architecture makes this kind of multi-source triangulation possible at scale.
What the Data Means for Your Business
If you’re in credit risk or trade finance: The 545,082 companies currently flagged for strike-off represent real counterparty exposure. Standard credit bureau checks may still show these as “active” — lag in downstream databases means the risk appears after the fact. Real-time registry monitoring is the only reliable safeguard.
If you’re in M&A or due diligence: XBRL account coverage of just 30.7% means automated financial analysis will hit hard limits for the majority of UK company targets. Scope your data requirements early.
If you’re screening suppliers or partners: The 213,222 companies with no SIC code registered cannot be reliably sector-screened. Flag these for manual review — they represent an outsized proportion of compliance unknowns.
If you’re in property finance or real estate investment: The concentration of 534,000+ companies in real estate SIC codes, combined with widespread use of SPV structures, makes this the single highest-volume sector for compliance monitoring. With 802,299 mortgaged companies tracked, charge monitoring alongside accounts compliance gives a materially better risk picture.
The Bottom Line
Filing compliance is not a bureaucratic nicety — it’s a leading indicator of business health, director engagement, and counterparty risk. The UK’s 5.9 million company registry contains deep patterns that simple status checks miss entirely.
The headline number bears repeating: 545,082 companies are already on the path to dissolution, and fewer than one in three active companies files machine-readable accounts. For any business making decisions based on corporate data, working only from surface-level checks means accepting a structural information disadvantage.
BORSCH.AI’s 50M+ signals across 53 government sources — including full Companies House accounts, filing history, mortgage registers, and officer records — are designed specifically to close that gap.
