London PI undertakes enquiries for private individuals, businesses and legal professionals. These may involve relationship concerns, surveillance, tracing, background research, commercial due diligence or investigation support connected with legal matters. We begin by understanding what you need to establish, then discuss the appropriate work and whether we can assist in your particular circumstances.
Of course. An initial conversation gives you an opportunity to explain the situation, ask questions and understand the options before committing to anything. We can talk through what you hope to establish and whether an investigation is likely to be helpful. You can then decide how you wish to proceed.
A short explanation is a good starting point. It helps to tell us what has happened, what you would like to find out, the area involved and whether there are any important dates. You do not need to have everything organised before getting in touch. If sensitive documents are relevant, we can first discuss a suitable way to share them.
Yes. Surveillance is available where it is appropriate to the circumstances and can be carried out lawfully. We will discuss the purpose of the assignment, the location and what information you are hoping to obtain, so that the proposed work is clearly understood before it begins.
Yes. We can consider enquiries involving company backgrounds, commercial disputes, due diligence and other business concerns. Every corporate matter is different, so we first establish the questions that need answering and the information already available. From there, we can explain what investigative steps may be useful.
Yes. We welcome enquiries from solicitors and other legal professionals. Assistance may include tracing, factual enquiries, background research and gathering information relevant to an existing or anticipated legal matter. We will discuss the purpose of the instruction, any deadlines and the form in which findings are required.
Our work is focused on London, including enquiries across its different boroughs. Some assignments may involve locations beyond the capital, which can be considered individually. If you let us know where assistance is needed, we can explain whether the proposed work is within our coverage.
The cost depends on the nature of the investigation, the amount of work involved and any particular reporting requirements. Once we understand your enquiry, we will explain the proposed charges and all fees will be agreed with you before any work begins. You will have the opportunity to consider the costs before deciding whether to instruct us.
Yes, written reporting can form part of an investigation. The level of detail will depend on the assignment, and we can discuss whether you require a concise summary, a fuller report or supporting material. Reporting arrangements are agreed at the outset so that you know what to expect when the work is completed.
We cannot promise a particular outcome, because an investigation may uncover information that differs from what was originally suspected. What we can offer is a clear explanation of the work proposed and an accurate account of the findings. Sometimes confirming that the available evidence does not support a concern is itself useful information.
We understand that people often approach an investigator about matters they would prefer to keep private. Your enquiry will be treated discreetly, and we will explain how relevant information is handled and who may need access to it for the agreed work. Our Privacy Policy sets out further details, including the legal circumstances in which information may have to be disclosed.
If records, messages or financial information are relevant to your enquiry, please explain what you are trying to establish. We can discuss lawful ways of obtaining or assessing information and whether any publicly available or authorised sources may help. Private accounts and confidential records cannot be accessed without the appropriate legal authority.
That will depend on the type of work and how much information is available at the start. Some enquiries may be relatively straightforward, while others require several stages or depend on developments outside our control. We will discuss an estimated timescale when the work is agreed and keep you informed if circumstances affect the schedule.
You are welcome to begin with a simple email to info@londonpi.co.uk explaining what you need help with. There is no need to prepare a formal brief: a few details about the situation and how we can reach you are enough to start the conversation. We can then discuss the next steps and whether an investigation would be appropriate.
For private, corporate or legal enquiries, use the form or the email address below. We are open six days a week and normally respond to emails within the hour. You are welcome to contact us with as much or as little detail as you feel comfortable sharing.
This website is operated under the name London PI. For privacy enquiries, contact info@londonpi.co.uk.
When you contact London PI, you may provide your name, email address, telephone number, information about your enquiry and any correspondence that follows. Information may also arise in the course of assessing or carrying out a separately agreed investigation. That may involve personal data about people other than the person making the enquiry.
Technical data, such as an IP address or basic server logs, may be processed by the website hosting provider.
Personal information may be used to respond to enquiries, assess whether services can be offered, communicate with prospective or existing clients, administer agreed work, maintain appropriate records, meet legal obligations and protect legal rights.
Processing must have a valid lawful basis under UK data protection law. The applicable basis may depend on the activity, for example steps requested before entering into a contract, performance of a contract, compliance with a legal obligation or a legitimate interest that has been properly assessed. Sensitive categories of data and criminal-offence data have additional legal conditions. We process personal information where it is necessary to respond to an enquiry, to perform a contract, or where we have a legitimate interest in providing investigation services, subject to your rights.
Investigation work may involve information about individuals who have not contacted London PI directly. Where this occurs, the information is obtained and used only as permitted by law, for a defined purpose, and only to the extent necessary. Depending on the circumstances, it may not always be possible or appropriate to provide notice to every individual concerned, for example where doing so would prejudice an investigation or is otherwise restricted by law.
Where appropriate and lawful, information may need to be shared with service providers supporting website hosting, communications or administration, and with professionals engaged on a particular matter. Information may also be disclosed where required by law. We do not sell personal information. Information may be shared with professional advisers or service providers where needed to deliver the service, or where required by law. We do not routinely transfer personal data outside the UK.
Information should be retained only for as long as necessary for the purpose for which it was collected, taking account of legal and record-keeping obligations. We keep personal information only for as long as needed for the purpose it was collected, including any legal or accounting requirements, and then delete or anonymise it.
Depending on the circumstances, you may have rights to access, correction, erasure, restriction of processing, data portability and to object to certain processing. Some rights are subject to legal limits and exemptions. Where processing is based on consent, consent may be withdrawn. To make a request, email info@londonpi.co.uk.
Right to object: where personal information is processed on the basis of legitimate interests, you may object to that processing, subject to applicable law.
If you have concerns about the handling of your personal information, contact London PI first. You may also complain to the UK Information Commissioner's Office at ico.org.uk.
This notice should be reviewed whenever the organisation's services, systems or information-handling practices change.
