Before you sign a contract or pay a deposit: how to check a British company in 5 minutes for free

The Companies House register is public and free. We show what to check about a business partner, builder or employer before you give them money.

Companies House – London

Every company registered in the UK has a public entry at Companies House. Searching it is free and needs no login. All you need is the company name, its number or a director’s name.

What you can check for free

  • Directors current and former, with a correspondence address.
  • Persons with significant control (PSC), i.e. the actual owners.
  • Filing history: changes, appointments, resignations.
  • Accounts and annual confirmation statements to download.
  • Deadlines: when the last accounts were filed and when the next are due.

What to watch out for

  • A company set up a few weeks ago that promises “many years of experience”.
  • A director who has run many companies that were closed or liquidated in a short time.
  • Accounts long overdue with no new filing.
  • A name on the contract or invoice that differs from the name on the register.

What it means for you

  • Individuals: check the building firm before paying a deposit for renovation work.
  • Workers: check the employer before you start work without a contract.
  • Businesses: check new customers and suppliers before sending goods on credit.

Our assessment

A register entry is not a certificate of honesty. But it shows who is really behind a company and whether it meets its obligations. Five minutes of checking can save thousands of pounds.

What to do

  • Go to Find and update company information and enter the company name or number.
  • Compare the company number with the number on the invoice or contract.
  • Save or print the entry on the day you sign the contract.
