Why Verifying a UK Company’s Legitimacy Is Crucial for Your Business
Working with an unverified or bogus business comes with real risks: lost payments, unenforceable contracts, exposure to VAT fraud, and potential damage to your reputation.
Checking Companies House for a UK Company
Companies House is the government’s official register of companies in England and Wales. Every limited company must be listed here.
How to Use Companies House for Legal Checks
- Visit Companies House register.
- Search by company name or company registration number (CRN).
- Confirm the details: company name, incorporation date, registered office, and filing history—all should match what is shown on invoices or websites.
- Make sure the company’s status says “Active.”
- Review annual accounts and confirmation statements to see if returns are filed on time.
Using the Company Registration Number (CRN) to Confirm Legitimacy
The CRN is a unique identifier for every company in the UK, issued at incorporation and crucial for verification.
Steps to Check a Company’s CRN
- Ask the business for its CRN—this should be shown on official documents and invoices.
- Enter the CRN at Companies House to instantly pull up the official record.
- Double-check that the business name, address, and details match those on the website or invoice.
- Treat any mismatch or failure to find a record as a major red flag.
Generate instant CRN searches and cross-check business details using our AI-powered verification tool for extra peace of mind.
How to Check UK Company Directors and Filing History
Verifying the people legally responsible for a company is essential. Under UK law, all directors and officers must be publicly listed on Companies House.
What to Check on Directors and Filing History
- Go to the “People” section of the company profile on Companies House.
- Check for recent, unexplained changes in directors—for example, many resignations or new appointments within a short time.
- Look for warnings such as compulsory strike-off actions (which mean the company may soon be closed by the registrar).
- Identify whether directors have been disqualified; Companies House will flag this on the company record.
Run a comprehensive director screening using our automated document review tools to highlight any high-risk business appointments.
Validating a UK Company’s VAT Number with HMRC
VAT registration is mandatory for UK companies with taxable turnover above the VAT threshold. If a company claims to charge VAT, its VAT number must be genuine and linked to their legal name.
How to Check a Business’s VAT Status
- Obtain the supplier’s VAT number—they should provide this on invoices or request.
- Check the number against the official GOV.UK VAT checker.
- Ensure the legal business name and address match the VAT record.
- Do not pay VAT charges if the number is not valid or is listed against a different business.
Track and store your VAT validations in our supplier onboarding workflow for compliance.
Industry-Specific Regulations: FCA, CQC, SRA, and More
Some industries require extra regulatory approval. Financial service firms need FCA authorisation; care providers must register with CQC; charities and legal practices are overseen by sector regulators.
Checking Industry-Specific Registers
- Financial services: Verify registration via the Financial Conduct Authority (FCA).
- Healthcare or social care: Confirm active status using the Care Quality Commission (CQC).
- Charities: Look up details on the Charity Commission register.
- Legal professionals: Search the Solicitors Regulation Authority (SRA) roll.
Steps:
- Search for the business using name or regulatory reference.
- Match addresses, any reference number, or trading names.
- Confirm their status is active, authorised, or current.
Automate your industry-specific compliance checks with our cross-referenced register search.
Spotting Online Scam Red Flags Before Making Payment
Even a company listed at Companies House can be a scam if their online presence doesn’t add up. Fraudsters pay for realistic websites and manipulate reviews to appear genuine.
What to Look for Online
- Check the website URL—fake companies often use domains close to the original or with spelling mistakes.
- Confirm the presence of a physical address and a verifiable landline. Avoid businesses that provide only a contact form or mobile.
- Use Google Maps to validate the address—look for real premises.
- Scan reviews on platforms like Trustpilot and Google. Be cautious of all glowing reviews with suspicious timing.
- Examine the website copy and images—generic text or stock photos may indicate a scam.
Our online verification tool can scan for missing business markers and inconsistent website details in seconds.

Frequently Asked Questions
How do I check if a company is registered in the UK?
Search its name or CRN on Companies House. All UK limited companies must be listed with full records of directors, addresses, and filing history.
Can I trust a business not on Companies House?
If you’re dealing with a supposed UK limited company not found on Companies House, be very sceptical. Sole traders and partnerships do not appear, but all UK limited companies must.
What are the warning signs of a scam company?
Red flags include no Companies House record, a missing or invalid VAT number, frequent director changes, no industry regulatory status, and only vague or suspicious reviews.
How do I verify a UK company’s VAT number?
Use the HMRC VAT checker online—ensure the company name and address match the VAT register.
Can a company look genuine but still be a scam?
Yes. Scammers may copy real company details or use dormant company registrations. That’s why you must cross-check different records and look for consistent, real-world business activity.
What should I do if I suspect a fake UK business?
Report it to Action Fraud and Trading Standards. Keep all emails, invoices, and evidence to help with investigation and possible claim support.
