When people hear the words private investigator, they often imagine Hollywood-style surveillance and unlimited access to personal information. In reality, UK private investigators are highly regulated and must work strictly within the law.
Still, a legally compliant investigator can uncover a surprising amount of information, far more than most people expect - using legitimate investigative techniques, open-source intelligence (OSINT) and specialised databases.
At Absolute Investigations, we’re often asked:
“What can a private investigator actually find out about someone in the UK?”
This guide breaks down exactly what we can and cannot legally discover in 2025.
What a Private Investigator Can Legally Find Out
1. Identity Information
A private investigator can confirm or uncover:
- Full name
- Date of birth
- Previous names or aliases
- Known associates
- Linked addresses
- Employment history (limited but verifiable)
This is done through open-source research, public records, and legally accessible databases.
2. Address & Residency History
If you need to trace a person, investigators can:
- Confirm their current address
- Map previous addresses
- Identify occupancy records
- Track movements or relocations
This is essential in cases involving debts, legal proceedings, missing persons, and fraud.
3. Financial Red Flags & Assets (Legal and Ethical Searches Only)
Private investigators cannot access bank accounts or credit files without consent.
However, they can identify:
- Business ownerships
- Directorships
- Company financial filings
- Property ownership (via Land Registry)
- Signs of financial distress or fraudulent behaviour
- High-value assets such as vehicles or investments (when publicly registered)
This is often used for pre-litigation support, fraud cases, and due diligence
4. Social Media & Online Behaviour
Most people underestimate what they reveal online. Investigators can legally examine publicly visible:
- Social media profiles
- Online activity
- Photos, posts, comments
- Location check-ins
- Online business listings
- Dating profiles
- Forum activity
This forms a crucial part of OSINT (Open Source Intelligence) investigations.
5. Employment & Professional Background
A PI can verify:
- Job titles
- Qualifications
- Companies worked for
- Professional licences
- Business networks
- Disciplinary records (if publicly accessible)
Extremely useful for employee vetting, CV fraud checks, and pre-employment screening.
6. Relationship Status & Personal Associations
Through a combination of open-source intelligence and field work, investigators may uncover:
- Relationship status
- Cohabitation
- Known associates
- Close connections
- Patterns of behaviour
This is commonly used in infidelity investigations and cohabitation cases relating to legal disputes.
7. Surveillance-Based Information
If surveillance is required and legal grounds exist, a private investigator can document:
- Movement patterns
- Daily routines
- Employment verification
- Who someone meets
- What vehicles they use
- Activities inconsistent with claims (e.g., injury fraud)
All surveillance is carried out discreetly and legally, in accordance with UK law.
What a Private Investigator Cannot Legally Access in the UK
To avoid misconceptions, here’s what NO investigator can access without explicit consent:
- Bank accounts
- Credit reports
- Mobile phone records
- Text messages or emails
- HMRC tax records
- Medical records
- Police databases (PNC)
- Private CCTV footage without permission
Any company promising these is operating illegally — and clients can be liable.
Is It Legal for a Private Investigator to Research You?
Yes - provided they follow UK law, including:
- Data Protection Act 2018
- GDPR
- Protection from Harassment Act 1997
- Regulation of Investigatory Powers Act (RIPA)
- Human Rights Act 1998
At Absolute Investigations, all work is conducted ethically, respectfully, and within legal boundarie
