Corporate and Employee Investigations in London
Discreet Corporate and Employee Investigations
At B25 Private Investigation, we help businesses establish the facts when they are dealing with suspected employee misconduct, fraud, theft, information leaks or other sensitive internal concerns.
Our corporate investigators can combine discreet surveillance, background research, evidence gathering and professional reporting to help you understand what is happening and decide what to do next.
We support business owners, employers, HR professionals, legal teams and organisations across the UK. Every investigation is planned around the specific concern, with a clear focus on confidentiality, proportionality and lawful working methods.
You can find out more about when a London business might need to a private investigator in this article.

Employee Surveillance in London
Discreet employee surveillance can help establish whether someone is acting inconsistently with information provided to their employer.
This may be relevant in cases involving:
- Suspected fraudulent sickness absence
- Unauthorised work for another business
- Breaches of restrictive covenants
- Misuse of company time or vehicles
- Contact with clients or competitors
- Undisclosed business activity
London surveillance can involve busy roads, public transport and movement between several boroughs. We will assess the likely movements of the subject and explain whether one or more investigators may be required.
Surveillance must have a legitimate purpose and be proportionate to the concern. Where disciplinary action may follow, businesses should also seek appropriate HR or employment-law advice.
What Can a Corporate Investigation Provide?
The evidence available will depend on the nature of the case and what is established.
A corporate or employee investigation may include:
- Dated surveillance observations
- Photographs or video footage
- Background and open-source research
- Checks into relevant business connections
- Records of movements and activity
- A clear written report
- Updates during the investigation
We cannot guarantee that an investigation will confirm an initial suspicion. Our role is to gather and report the facts accurately and impartially.
