Liverpool Investigative Services

Working on corporate, legal and private investigations in Liverpool, we ensure our strategies are objective and proportional to the situation. Our investigators are highly skilled professionals, dealing with issues that range from employee theft to infidelity.

In some cases, our services are required to find someone important to our clients or to serve legal documents directly to someone who needs to attend court. We provide person tracing, enquiry agents and process serving in Liverpool.

Our private investigators in Liverpool keep up with local businesses and events which may provide useful intelligence. We adjust our techniques to the environment, whether in the dockside areas in Vauxhall or the rural areas of Ormskirk. Our investigations may include covert surveillance, GPS vehicle tracking and bug sweeping. We also provide Lie Detector or Polygraph testing, facilitated by trained and accredited experts in Liverpool.

All evidence is reported to a high standard, giving you the reassurance you need to move forwards confidently. Because our investigations are planned on a case-by-case basis, each case begins with a conversation with our Liverpool private investigators. We also offer a discreet call-back service, allowing you to keep your enquiries confidential.

How Can We Help

How do I prove that somebody is still driving while they are banned?

Surveillance | Vehicle Tracking

There are two elements to this scenario, the first being that the individual’s vehicle is being driven, and the second being that the banned individual is the one driving it. If reports of a banned driver getting behind the wheel are to be substantiated, we will need to prove both of these elements.

At RevealPI we are equipped with GPS vehicle tracking devices which can be used to monitor a vehicle remotely. The devices are small and magnetic, making them quick and easy to attach and detach from a vehicle without leaving a mark. Our team of investigators are trained in discreetly attaching a tracker, perhaps bending to tie their shoelace or pick up something they have dropped near the vehicle. We never attach a tracker somewhere visible or where it will be detected during car maintenance or an MOT check. Once the tracker is attached it can be left for a time and will continue to report GPS data to our team. This data will be reported daily in a spreadsheet format and we can use it to discern a pattern.

Should we see the vehicle being driven, we can use this pattern of behaviour to decide an appropriate time to conduct surveillance and prove who is driving the vehicle. Our investigators are trained in covert surveillance, behaving discreetly to avoid raising the suspect’s suspicions and causing them to change their behaviour. We use long lens cameras to collect detailed photographic and video evidence over long distances, and hidden, body-worn cameras to record in close quarters.

Using GPS Vehicle Tracking and Surveillance in combination, we could easily gather robust, timestamped evidence that someone is driving while banned.

I’m concerned that staff might be stealing from my business.

Employee Investigations | Surveillance

Business owners who see discrepancies in their stock reporting systems may raise questions about employee theft, which costs businesses in the UK thousands of pounds every year. However, even though the numbers show stock or cash is going missing, it is often difficult to find out for certain who is taking it. Questioning staff would reveal the investigation and risk tipping off the thief before evidence can be gathered.

Our investigators are skilled in multiple surveillance methods, including the use of hidden cameras and listening devices. By positioning these in your business premises, we may be able to capture video evidence of how things are going missing. Depending on the type of business and items being taken, it may be appropriate to survey the exterior of the building, such as the delivery bay or staff car park, in case bulky items or large amounts of stock are being redirected.

I need an address to take somebody to small claims court.

Person Tracing

If you need to take somebody to court, but don’t have enough details for them to complete the court papers, Person Tracing can be a helpful and fast service. As court proceedings are deemed a reasonable cause for tracing an individual’s contact details, we are usually able to collect this data for you. Simply provide us with as many details as you do have, such as a name, phone number or workplace address, and we will use our experience and knowledge to provide the address as soon as possible.

I think my partner might be cheating

Matrimonial Investigations | Surveillance

Infidelity is a breach of trust causing real emotional harm and relationship breakdown. When clients come to us with relationship problems, we do our best to treat the case with the sensitivity and emotional awareness warranted. We will invite you for an initial consultation and assign a key point of contact who will be your support throughout the investigation. During this consultation, you can tell us your suspicions and any details which will help us begin the investigation. It may be that your partner is claiming to work long hours, but their pay isn’t changing, or that they are out with friends a lot but their stories don’t add up.

Matrimonial Investigations often involve surveillance as standard. Because infidelity often recurs in a pattern, we can use the details you give us to identify an appropriate time and place to conduct surveillance. This may be from outside their workplace or home address, waiting for them to leave the premises and following them to their next location. We will provide photographic evidence of any relevant interactions, with time and date stamps to leave you with no doubts. Our evidence is reported sensitively and to the highest standard, meaning that it is admissible in court should you need it to be.

Private conversations seem to be getting leaked

Bug Sweeping

Because we are experts in surveillance, we are also experts in detecting when someone is being watched or listened to without their permission. We have helped clients from the corporate world and as individuals to uncover how their private conversations are being shared more widely than they intended. In corporate or government situations, bugs or listening devices are used to gather classified information which can be sold for a price to competitors, or used to undermine employee investigations. In personal situations, such as a listening device in your home, it is more likely that the person monitoring you seeks harmful levels of control.

By assessing the information which has been leaked, and the locations in which this information was discussed, we can narrow down the possible places where a listening device may be hidden. Our team can then attend your property or office and search for bugs in this location. We do this without damaging any items or furnishings, and we will never discuss what we are doing there with others. To an outsider, we will appear as a general maintenance crew.

Once a listening device is found, the next step is to discover who planted it. How we do this will depend greatly on the type of device and location, and on other details of the case such as where the leaks originally surfaced to alert you that someone was listening.

We suspect an employee was involved in an incident, but we have no evidence.

Lie Detector Test

If you know an incident took place, and have a good idea of who was involved, gathering evidence is the best way to confront them and take action. However, sometimes evidence is lost or cannot be gathered safely. In this instance, a polygraph or lie detector test will help narrow down the suspects and help you move forward.

A lie detector test measures physiological signs of stress such as blood pressure, pulse and perspiration, working on the idea that these symptoms increase significantly when someone lies. All our lie detector tests are conducted by trained and accredited professionals, who ask questions from different angles to ensure any twists in the truth, which may enable someone to lie confidently, are straightened out. We facilitate the tests in controlled environments to reduce the risk of adverse results or false positives, and provide you with a full report of the results.

Why Trust Us?

At Reveal PI, we understand the need for discretion and the importance of protecting our clients anonymity. From the way we communicate with our clients, right through to the techniques we use and the approach we take when conducting investigations, discretion remains our priority.

We leave nothing to the imagination, once our team has completed your investigation you will be presented with a detailed report that meets the highest of standards and is admissible as evidence in a court of law. A combination of high definition video footage and time stamped photography will allow you to feel as though you were there to witness the events in person.
