Why Choose Us for Your London Investigation

Our London office has been running investigations across the capital for over 29 years. That experience shapes every case we take on.

A Fixed Office in the Capital

Our office at 124 City Road is available for meetings by appointment. The private investigation agency can also discuss the case by telephone when an office visit is unnecessary.

Experience Matched to the Case

The private investigator assigned to your enquiry will be chosen for the work required. Our professional investigators cover personal, legal and corporate matters.

Clear Scope and Costs

A private investigator will explain what work is proposed, what information may be available and what could change the timescale or price before an instruction begins.

Lawful Evidence and Reporting

Your private investigator will keep a clear record of observations and findings. Reports distinguish evidence from assumptions and can be prepared for you or your legal adviser.

Discreet Field Work

When investigation services such as surveillance are appropriate, the private investigator plans the work around the facts of the case. Our local detectives carry out field enquiries discreetly.

Clear Communication

Case information is limited to the people handling the agreed work. Updates and reports are supplied through the contact method agreed with you.

Frequently Asked Questions: London

Do you have a private investigator based in London?

Yes. Our office is at 124 City Road and meetings are available by appointment. A private investigator can usually discuss the enquiry by telephone first, which allows us to establish what work may be suitable before arranging a meeting or field work.

How quickly can a private investigator start?

The starting time depends on the service and the information available. Tracing and background checks can often begin after the scope has been agreed. Surveillance needs planning, so a private investigator will confirm the proposed dates and resources before work starts.

Which areas can a private investigator cover?

Our local detectives cover all Greater London boroughs and surrounding counties. The investigator considers the location, travel pattern and likely timings when field work is planned. Many private investigator services, including research and tracing, can be handled without the client visiting the office.

Is my enquiry confidential?

Yes. Information is limited to the people who need it for the agreed work. Your private investigator will explain how reports and evidence are supplied. We will not contact the subject of an enquiry unless that forms part of an agreed and lawful instruction.

How much does a private investigator cost?

Costs depend on the service, the time required and the number of investigators involved. A tracing enquiry is priced differently from mobile surveillance. The private investigator will set out the proposed work and price before you decide whether to proceed, with fixed fees used where the scope allows.

Will the person know that a private detective is investigating?

Discretion is part of the planning for every case. Surveillance is intended to record relevant activity without drawing attention to the investigator. No private detective can promise that a subject will never notice anything, but the risks and practical limits are considered before the work begins.

Can evidence gathered by an investigator be used in court?

A private investigator can prepare dated observations, supporting material and a written report for your solicitor. Evidence must be gathered lawfully, but its admissibility is decided by the court and the legal advisers involved. We do not describe evidence as guaranteed to be accepted.

What private investigator services do you offer?

Investigation services include relationship investigations, discreet investigations, people tracing, background enquiries, business enquiries, asset tracing, fraud enquiries and surveillance. Private detective services can be combined when a case requires more than one line of enquiry, but each part of the work is agreed before it starts.

Is it illegal to hire a private investigator in the UK?

No. It is lawful to hire a private investigator for a legitimate purpose. The methods used must also be lawful. We will not offer access to private bank records, unlawful tracking or information obtained by deception, and we will explain when a requested check cannot be carried out.

Is it worth hiring a private investigator for infidelity concerns?

That depends on the question you need answered and how you intend to use the findings. A private investigator can explain whether surveillance is likely to provide relevant evidence. A private detective should also tell you when the proposed work is unlikely to justify the cost.
