Discreet Private Surveillance in London

B25 Private Investigation provides professional surveillance services throughout London for private individuals, businesses and legal professionals.

Our experienced surveillance investigators can discreetly monitor movements and activity, gather factual evidence and provide a clear record of what has been observed. We assist with sensitive personal matters, employee concerns, suspected fraud, breaches of contract and other situations where reliable information is needed.

Every surveillance operation is carefully planned around your objectives, the location and the likely movements of the person concerned.

When Might You Need a Surveillance Investigator?

Surveillance can help establish the facts when you have a genuine concern but do not have enough evidence to make an informed decision.

Our London surveillance services may assist with:
Relationship and Infidelity Concerns: Establishing whether a partner’s movements or activities are consistent with what you have been told.

Employee Investigations: Investigating suspected fraudulent sickness absence, unauthorised secondary employment or misuse of company time and resources.

Breach of Contract Investigations: Gathering evidence where a current or former employee may be approaching clients, working for a competitor or breaching restrictive covenants.

Fraud Investigations: Monitoring activity connected with suspected insurance fraud, false claims, theft or other dishonest behaviour.

Stalking and Harassment Concerns: Helping document patterns of behaviour where someone believes they are being followed, watched or harassed.

Legal and Family Matters: Gathering evidence that may assist a solicitor or support an ongoing legal matter.

A surveillance investigation should be based on a defined concern. Our role is to report what is observed accurately, not to confirm assumptions.

How Does Private Surveillance Work in London?

Before surveillance begins, we will discuss what you need to establish and gather the information required to plan the operation.
This may include relevant addresses, vehicle details, photographs, usual routines and the dates or times when useful activity is most likely to take place.

London presents particular operational challenges. A subject may travel by Underground, bus, train, taxi or on foot, while congestion and busy public spaces can make surveillance more complex. We will assess whether one or more investigators are required and explain the recommended approach before work begins.

What Evidence Can Surveillance Provide?

Where relevant evidence is gathered, this may include:

Dated and timed surveillance observations,
Photographs,
Video footage,
Details of locations visited,
Records of movements and relevant activity,
A written surveillance report.

The evidence available will depend on what takes place during the agreed period. No professional investigator can guarantee that surveillance will produce a particular result.

B25 will provide a factual account of what was observed without exaggeration or unsupported conclusions.

Is Private Surveillance Legal in London?

Private surveillance is legal in the UK including London when it is carried out for a legitimate purpose and using lawful, proportionate methods.
Surveillance investigators can observe and document activity taking place in public locations. They cannot trespass, hack private accounts or use unlawful methods to obtain information.
We will assess the purpose of the investigation before accepting an instruction and explain what can realistically and legally be achieved.

Where evidence may be used for disciplinary action or legal proceedings, you should also seek advice from an appropriate solicitor or HR professional.
