Every case is handled with professionalism and discretion, in line with UK law, and we keep you updated so you always understand how the investigation is progressing.
Private investigation services across Marylebone and Central London
From the boutiques and restaurants around Marylebone High Street to the professional practices on Harley Street, the busy routes near Baker Street and the open spaces around Regent’s Park, the area has a distinctive character and pace. Our investigators are familiar with these surroundings and tailor each operation to the environment, choosing the right vantage points and timings to collect reliable evidence while remaining unobtrusive.
For private clients, we can assist with concerns about a partner’s movements or behaviour, suspicions of infidelity, safeguarding and welfare questions, harassment or stalking, problems arising from online or app-based relationships, and tracing people with whom you’ve lost contact. You’ll work with a dedicated investigator who explains your options clearly, agrees a realistic plan and remains your main point of contact throughout.
For companies, professional practices and legal teams, we offer covert surveillance, detailed background and due-diligence checks, internal misconduct and theft enquiries, fraud investigations, and practical support for ongoing legal or regulatory matters. Our findings are presented in clear, structured reports that are straightforward to share with solicitors, HR teams, insurers or other advisers when required.

FAQs
Answers to common questions about our professional surveillance services.
What areas do you cover from Marylebone?
While this page focuses on Marylebone, our investigators work across central and West London, including Fitzrovia, Mayfair, Soho, Paddington, Regent’s Park and the surrounding neighbourhoods. We can also travel throughout the UK and may be able to assist with cases that involve activity in more than one country.
What types of cases do you handle in Marylebone?
We support private individuals, families, businesses and professional advisers. Typical instructions include relationship and infidelity investigations, background checks, locating missing persons or debtors, child and welfare enquiries, monitoring employees or contractors, internal theft and fraud cases, and surveillance linked to ongoing disputes. If your circumstances are a little different, you’re welcome to contact us for a confidential discussion.
Will my enquiry be kept confidential?
Yes. Confidentiality is fundamental to the way we work. Your enquiry and any information you share with us are treated in strict confidence, and we do not pass details to third parties without your consent. Our investigations are designed to minimise the likelihood of the subject, or those around them, realising that a private investigator has been instructed.
How much does a private investigator in Marylebone cost?
The cost of an investigation depends on several factors, including the complexity of the case, how many investigators are required, the techniques we need to use and the anticipated duration of the work. After an initial conversation, we’ll recommend a practical approach and provide a clear outline of likely fees so you can decide whether to proceed. There are no hidden extras, and we’ll agree the budget with you in advance.
How quickly can you begin work on a case?
In many situations we can start relatively quickly, particularly if there is a specific date, event or pattern of behaviour that needs to be observed. Once we understand your objectives and the background, we’ll propose a plan of action and confirm how soon our team can be deployed.
Do I have to meet you in person?
Not unless you would prefer to. Many clients are comfortable handling everything by telephone, email or secure video call, and most investigations can be managed this way. If you would feel more at ease meeting face-to-face, we can arrange a discreet appointment in Marylebone or elsewhere in central London at a convenient time.
