How to Verify a UK Company Before Investing
Angel investors and syndicates need to verify UK startups quickly before committing capital. This guide explains how to check company legitimacy and identify red flags using Companies House filings and public data.
Step 1: Verify Companies House Registration
Every UK company must be registered with Companies House.
Check Active Status
Search the free Companies House register:
- Confirm the company is "Active", not "Dissolved" or "In Administration"
- Verify incorporation date matches what founders claim
- Check registered office address is real, not just a virtual office service
- Review company type (Ltd, PLC, LLP) aligns with investment structure
Red flag: Companies dissolved within 2 years or multiple dissolved companies linked to same directors.
Review Filing History
Check governance and compliance:
- Annual accounts filed on time (due 9 months after year-end)
- Confirmation statements submitted annually
- No outstanding penalties or late filing markers
- Consistent filing pattern over company lifetime
Red flag: Missing or late filings indicate poor financial management or cash flow problems.
Verify Director Details
Check all listed directors:
- Names match LinkedIn profiles and pitch deck
- No disqualified directors (search GOV.UK register)
- Relevant sector experience for founding team
- Check other companies where directors are or were appointed
Red flag: Directors with history of dissolved companies, disqualifications, or no verifiable professional background.
Step 2: Check PSC Register
The Persons with Significant Control register shows ownership structure.
Review Ownership
Check who controls the company:
- Identify individuals with more than 25% shares or voting rights
- Verify PSC names match founder claims
- Check for offshore entities or complex nominee structures
- Confirm founders hold significant equity stakes
Red flag: Hidden ownership, nominee PSCs, or founders with minimal equity.
Verify Share Structure
Look for unusual patterns:
- Excessive share classes that dilute founder control
- Recent share transfers before fundraising
- Nominee shareholders registered to addresses outside UK
- Corporate PSCs with opaque ownership chains
Red flag: Complex structures that obscure actual control or recent suspicious transfers.
Step 3: Review Financial Filings
Check available accounts for financial health signals.
Analyse Latest Accounts
If accounts are filed (not all startups file full accounts):
- Review turnover growth or decline year-over-year
- Check profit/loss and cash position
- Look at director remuneration levels
- Assess debts and liabilities
Red flag: Declining revenue, mounting losses without funding, or excessive director pay in loss-making startups.
Check Funding and Solvency
Look for financial stability indicators:
- Cross-reference Crunchbase for recent funding rounds
- Check for charges or mortgages on Companies House (indicates secured debt)
- Look at current assets vs. current liabilities ratio
- Review auditor reports for any qualifications (if audited)
Red flag: High debt, charges from lenders, or qualified audit opinions.
Step 4: Cross-Reference Digital Signals
Verify founder claims against public sources.
LinkedIn Verification
Check founding team profiles:
- Verify employment history matches pitch deck claims
- Confirm education and qualifications
- Check professional network and endorsements
- Look for connections to reputable investors or advisors
Red flag: LinkedIn profiles created recently, minimal connections, or employment gaps.
Market and Traction Signals
Look for evidence of genuine business activity:
- Company website showing real product or service
- LinkedIn shows team growth and active hiring
- Search "[company name] UK" for news or press coverage
- Check Glassdoor for employee reviews (if scale permits)
Red flag: No web presence, no team growth, or negative employee reviews about unpaid wages.
Pre-Investment Verification Checklist
Before committing to due diligence:

When to Walk Away
