How to run a lawful background check on someone in the UK

Private investigators start every background check the same way: confirm they have the right person, then work outwards from official records. You can do much of this yourself, legally, from public sources.

01Have a lawful reason

Under UK GDPR you need a legitimate purpose, such as vetting a business partner or tenant. Keep only what is relevant.

  • ✓Write down why you are checking
  • ✓Avoid health, religion, politics and other sensitive details

02Confirm identity before anything else

Most mistakes come from mixing up two people with similar names. Match several details before you trust a record.

  • ✓Full name and any previous names
  • ✓Approximate age and town
  • ✓Employer or company they say they run

03Check company appointments

Companies House lists every director appointment, current and past.

  • ✓Companies they have run and how those ended
  • ✓Any disqualification

04Check insolvency and court records

Bankruptcies and individual voluntary arrangements are public.

  • ✓Individual Insolvency Register
  • ✓County Court Judgments in the last six years

05Verify professional claims

Regulated professionals appear on public registers.

  • ✓FCA register for financial advisers
  • ✓SRA for solicitors, GMC for doctors, ICAEW for accountants

06Review the public online footprint

Look for a consistent story across public profiles, press and reviews.

  • ✓Employment history that matches LinkedIn
  • ✓Profile photos that appear under other names

07Know what is off limits

Investigators cannot legally obtain bank, phone, medical or criminal records by deception, and tracking someone's car without consent can be harassment.

  • ✓No pretexting or fake identities
  • ✓No GPS trackers
  • ✓Criminal record checks go through DBS with consent
