As leading private investigators in the UK, we are often asked if we can access someone’s private communications to confirm suspicions of infidelity. People want the truth, but hacking is not the answer and will put you at legal risk.

Can a Private Investigator Hack a Phone or Account?
No. Private investigators cannot legally hack phones, social media accounts, emails, or messenger apps. Accessing someone’s device or account without consent breaches criminal and civil law in the UK. It also risks contaminating your case if you later need to rely on evidence.
Please do not contact us requesting hacking services. We do not offer or support anything illegal.
Why You Should Avoid So-Called Phone Hacking Services
We regularly hear from people who were scammed after paying so-called ethical hackers who promised access to WhatsApp, Instagram, or call logs. In every case, the operator was fraudulent or operating illegally. Typical signs include pressure to pay by crypto or gift cards, repeated upsells, and refusal to provide a registered UK business address.
- If a site claims live access to private chats, it is either a scam or a crime.
- Using hacked data could expose you to criminal liability and damage any legal claim.
Can Private Investigators Trace Phone Numbers?
Tracing a phone number is a separate, legitimate service. In some cases we can attribute a number to a name, address, or likely user using lawful open sources and investigative techniques. This is useful to identify unknown callers or to support a wider investigation.
Important: we do not access phone records or intercept communications. All work is based on lawful sources and consent where required.
How Do Private Investigators Catch Cheaters Legally?
There are effective, lawful routes that protect your position if you later need to take action.
- Personal surveillance to document meetings, timings, and movements discreetly.
- GPS intelligence where lawful and proportionate to target surveillance windows more efficiently.
- OSINT checks to uncover public dating profiles, alternate identities, and timeline conflicts.
- Facial recognition background checks across public sources to identify adult content links or alias use where lawful.
Our surveillance services are discreet and lawful, and produce evidence that is far more defensible than anything obtained by hacking.
The UK Phone Hacking Scandal
The News of the World case showed how serious unlawful interception is. A private investigator and senior editor were convicted for voicemail interception, with custodial sentences imposed. The message is clear. No reputable UK PI should offer or attempt hacking.
Are You the Victim of Electronic Surveillance?
If you suspect your phone or accounts are compromised, take immediate steps:
- Change passwords and enable two factor authentication on all services.
- Review account login history and revoke unknown sessions.
- Back up then factory reset devices you believe contain spyware.
Those willing to install software may also plant physical bugs such as hidden microphones or cameras. Consider a professional sweep if you have repeated warning signs.

Common Myths and Realities
- Myth: A PI can read WhatsApp if you give them a number. Reality: Impossible without consent or unlawful access.
- Myth: Deleted messages can be pulled remotely. Reality: Remote extraction without consent is unlawful. Device owner cooperation is required for any forensic work.
- Myth: Everyone is doing it quietly. Reality: Those who try are committing offences and risk prison. Courts also reject unlawfully obtained evidence.

No. Networks will not release call or message content to private parties. We do not request or obtain private telecoms data.
