The COCOO-Companies House Doctrine: A Strategic Model for Sectoral Dominance

This doctrine establishes the protocol for interrogating the UK’s official company register via its Advanced Search function. This is not a simple directory lookup; it is the engine room for all of COCOO’s UK-based market analysis. We use this platform to dissect entire industries, identify every player in a given market segment, detect clandestine consolidation, and create the foundational evidence for our most potent strategic plays, including StealthConsolid, Competitor Analysis, and FOC DAM (Find Other Claimants, Monetize Damages).

1. Core Principles of Interrogation

Our use of Companies House Advanced Search is governed by the core tenets of the COCOO framework. We are not just finding companies; we are mapping the entire battlefield.

  • Sectoral Supremacy: Our primary mission is to achieve informational supremacy over any given market sector. The Standard Industrial Classification (SIC) code search is our principal weapon to achieve this. It allows us to move beyond analyzing individual companies and instead analyze the entire population of a “highly segmented market,” which is the primary hunting ground for our strategic interventions.1
  • StealthConsolid as a Primary Target: The mind maps identify StealthConsolid as a key threat and opportunity.5 Our doctrine mandates using the SIC code filter to define a niche market (e.g., veterinary services, dental clinics) and then analyzing all companies within that code for patterns of common ownership or sequential acquisition that fall below normal merger notification thresholds.
  • Systematic Competitor Analysis: To conduct Porter and Benchmarking analyses, we must first define the universe of competitors.5 The SIC code search is the definitive tool for creating a comprehensive list of every company operating in a target’s space, from major players like Travis Perkins down to the smallest local businesses.
  • Victim Identification Engine (FOC DAM): When a single company is harmed by anti-competitive conduct, it is rarely an isolated incident. We use the victim’s SIC code as a “search key” to instantly generate a list of every other company in the same line of business. This list is our primary pool of potential co-claimants, allowing us to rapidly scale a single grievance into a powerful, multi-party action.5

2. Weaponizing the Platform’s Arsenal: Capabilities and Search Rules

Mastery of the Companies House Advanced Search interface is fundamental. Its power lies in the ability to combine multiple filters to surgically isolate specific cohorts of companies.1

  • Official Search Rules & Functionality:

    • Access: The advanced search is a free tool available on the “Find and update company information” service.1
    • Nature of Business (SIC Code): This is our most powerful filter. We can search for companies registered under one or more specific 5-digit SIC codes. This allows us to define a market with precision.1
    • Company Status: We can filter to show only active companies, or include dissolved, in liquidation, or other statuses. This is critical for focusing on live targets or analyzing market churn.1
    • Incorporation Date: We can search for companies incorporated within a specific date range. This allows us to monitor new entrants into a market.1
    • Location: We can filter by registered office address, including postcode. This is essential for analyzing local or regional market structures.1
    • Company Name: We can search for names that include or exclude certain keywords, useful for finding companies with specific branding (e.g., “eco,” “green”).1
    • Data Export: Search results can be downloaded as a spreadsheet (up to 5,000 companies), enabling offline analysis and integration with other datasets.4

  • SIC Code Structure: Understanding the hierarchy is key. SIC codes are structured from broad to specific, allowing us to adjust the scope of our analysis.7

    • Section (Broadest): e.g., Section C – Manufacturing
    • Division: e.g., Division 10 – Manufacture of food products
    • Group: e.g., Group 10.5 – Manufacture of dairy products
    • Class (Most Specific): e.g., Class 10.51 – Manufacture of dairy and cheese

3. Strategic Interrogation: The Questions We Ask

We interrogate this platform with precise, mission-oriented questions designed to generate actionable intelligence.

  • For StealthConsolid & MATOIPO Analysis:

    • “How many active, private limited companies are registered under SIC code 86230 (Dental practice activities) in the UK? Who are the directors of the 20 most recently incorporated ones?”
    • “Generate a list of all companies with SIC code 62012 (Business and domestic software development) that have a registered office in the ‘Silicon Roundabout’ postcode area (e.g., EC1V). Are there common directors or parent companies appearing across this list?”
    • “A private equity firm, “, is acquiring mid-sized logistics companies. Give me a list of all UK companies with SIC code 52290 (Other transportation support activities) and an incorporation date between 2010 and 2020 to identify their next potential targets.”

  • For Competitor Analysis & Benchmarking:

    • “Who are the main UK competitors to the German supermarket chain Lidl? Generate a list of all active companies registered under SIC code 47110 (Retail sale in non-specialised stores with food, beverages or tobacco predominating).”
    • “We are analyzing the UK construction materials market. Provide a list of all active companies with SIC code 46730 (Wholesale of wood, construction materials and sanitary equipment). How many of these are located in the North West of England?”

  • For FOC DAM (Victim Finding):

    • “A small advertising agency (SIC 73110) has been harmed by the anti-competitive practices of a major online platform. Provide a list of all other active companies registered under SIC 73110 in the UK. This is our target list for finding co-claimants.”
    • “A farmer has been unfairly treated by a major food processor. Generate a list of all companies under SIC code 01450 (Raising of sheep and goats) and 01420 (Raising of other cattle and buffaloes) to identify other potential victims for a collective action.”

4. The COCOO-Companies House Strategic Playbook: A Model for Action

The following playbooks provide standardized workflows for using this platform to achieve our strategic objectives.

Playbook A: The “Sectoral Census” Protocol

  • Objective: To create a comprehensive, foundational map of every single company operating within a defined UK market segment. This is the mandatory first step for any sectoral investigation.
  • Execution:
    1. Define the Market: Identify the 5-digit SIC code that most accurately represents the target market. Use the official condensed list on GOV.UK to ensure accuracy.8 Example: For a case involving accounting firms, use SIC code 69201 (Accounting and auditing activities).
    2. Execute the Search: Go to the Companies House Advanced Search page. Enter the SIC code into the “Nature of business” field. Set the “Company status” filter to “Active”.1
    3. Export Data: Run the search and download the results as a spreadsheet.4
    4. Initial Analysis: The resulting list is your “Sectoral Census.” It provides the total number of active players, their names, incorporation dates, and registered locations. This is the raw data for market share analysis and Benchmarking.
  • Strategic Outcome: This provides an unimpeachable, data-backed overview of the competitive landscape, forming the evidentiary foundation for any subsequent complaint or market study submitted to a regulator.

Playbook B: The “Stealth Consolidation” Hunter

  • Objective: To detect patterns of creeping acquisitions in highly segmented markets, creating the evidence needed to trigger a regulatory review.
  • Execution:
    1. Identify Niche Market: Select a highly specific SIC code representing a fragmented market ripe for consolidation. Example: SIC 86900 (Other human health activities), which includes physiotherapy clinics.
    2. Filter by Location & Age: On the Advanced Search, enter the SIC code and add a location filter (e.g., “South East”) and an incorporation date filter (e.g., from 10 years ago to 2 years ago) to focus on established, independent businesses.1
    3. Analyze the Output: Download the list. Now, pivot to other tools. Take the names of the directors from this list and search them on OpenCorporates to see if any individuals appear as directors for multiple companies.
    4. Identify the Acquirer: A common pattern is that a large consolidator (e.g., a major healthcare private equity fund like [e.g., Apposite Capital]) will acquire a local clinic. The original directors resign and are replaced by directors from the acquirer. By cross-referencing director names, we can identify the hidden parent company behind dozens of seemingly independent local clinics.
  • Strategic Outcome: This playbook allows COCOO to piece together a mosaic of small, non-notifiable deals into a single, compelling picture of market concentration, providing the CMA with the evidence it needs to launch an investigation into a MATOIPO event that has occurred “under the radar.”

Playbook C: The “New Entrant” Monitor

  • Objective: To identify and profile new companies entering a specific market, allowing for early analysis of potential disruptors or future acquisition targets.
  • Execution:
    1. Define Market: Select the relevant SIC code for the industry you are monitoring. Example: SIC 62020 (Information technology consultancy activities).
    2. Set Temporal Filter: On the Advanced Search page, enter the SIC code. In the “Incorporation date” fields, set a recent date range (e.g., “From” 1 month ago “To” today).1
    3. Run Recurring Search: Save this search query. Run it on a weekly or monthly basis to generate a continuous stream of intelligence on all new companies entering the sector.
    4. Profile the Entrants: For any interesting new entrants, conduct a full intelligence workup: Who are their directors (via OpenCorporates)? Are they funded by venture capital (via RNS announcements on other platforms)?
  • Strategic Outcome: This playbook creates an early-warning system. It allows COCOO to spot the next innovative competitor or potential partner before the rest of the market, providing a significant strategic advantage in a dynamic industry.
