Private Investigator Costs UK

Affordable Investigation Service – How Much Does It Cost

An hourly rate can seem high when you do not know what will be accomplished or how long this might take. Due to this, it may be tempting to hire a less experienced, cheaper private investigator. However, they might take more time than experienced investigators, and this will likely cost you much more. Unethical practices could also result from not meeting the standard of proof required by a court or tribunal.  Additional to the cost of the services you require, you may be charged for travel time, mileage, report writing, food and beverage, entry fees, and parking fees incurred during the investigation.

Our private investigator agency offers daily rates to clients worldwide, usually for private investigations lasting longer. Fixed rates consider the hourly rate, travel time, mileage, and the final report — thus giving you a clear understanding of your costs upfront.  Costs are important when considering what private investigator to choose in the UK, but getting it wrong can have dire consequences. Hiring a private detective in the UK that is more results-oriented than money-oriented, and who will do their best to obtain the required evidence you require in the quickest time possible is the investigation company worth considering.

Private Investigators UK

Private Investigator Q&A

Hiring a private investigator does not violate any rules of law, in the UK. However, there is certain conduct that private investigators cannot engage in or else they will be violating the law. You should check with the private investigator, before you hire them, that they follow all the rules and laws for private investigation.  Following a set of rules and procedures with individual discretion, private investigators in the UK can ensure that all investigative work is completed to the highest standard and is fully admissible in a court of law. The investigative techniques utilised by a private investigator can differ from one company to another. However, most companies will use various methods to obtain information for either individual or corporate purposes.  

The information gathered should assist in surveillance and intelligence gathering only and should not be presented to a court on its own. Our GPS trackers cannot ensure the desired information because it is contingent on who is driving the vehicle – unless the driver is under surveillance.

Static Surveillance – Undertaken by one operative.  Carefully positioned outside a property and will film and record the movements of a person, or persons at an address or location in the UK.  Mobile Surveillance – When required to follow a person/persons. Undertaken by a team, whether that be two, three, four or more.  We have the capabilities of utilising various vehicles applicable to the job and all the latest technology and equipment to capture the required evidence for our clients throughout the UK.  Rural Surveillance  – Required when tasked to monitor a scenario while in a rural area. Depending on the circumstances, this can usually be conducted by one private investigator.

There are no two cases alike, and to determine the cost, several factors must be considered, including methods of delivery, number of hours, number of operatives to be provided for the investigation to be conducted professionally, mileage, and any other special resources required for the investigation to succeed.  Typical cost are between £35.00 - £125.00 per hour.

A private investigator is often useful for a number or reasons, but when a case or claim is necessary in a court of law, these professionals are invaluable at finding information and revealing the whereabouts of needed witnesses. It is important to contact a private investigator when anything that requires extensive research or surveillance is involved.

GPS Tracking – This can be used 24 hours a day, 7 days a week. It involves fitting a very small tracking device to a car or vehicle, the device then sends signals to a designated satellite. It is a very reliable method, used often by private investigators to solve cases, such as cheating partners. However, it can only be used if you have consent from the individual, such as with business cars or your own car that someone else is driving.

Covert Surveillance – They can only follow someone if it is in a public place. Private investigators cannot follow anyone in a private place, such as a home or private property. This method can provide evidence of where someone has been, when they have been there and who they were there with.

Public and open source records – Public records give private investigators a wide range of information about somebody. Normally, these records can be accessed through the county courthouse, or sometimes through an aggregator (website or program that can collect, or give out, information about an individual). Often, the basic records can lead private investigators to other information and other leads to follow. The basic information can also help private investigators start their investigations.

Perform background and history checks – Legally, private investigators can do very thorough background and history checks on individuals or businesses. You will not be able to do a search as thorough, if you were to do it yourself. The checks vary from online searches, social media checks, criminal record checks or even public records.

Bug or hack phones – Private investigators can never hack or bug phones, as it is unethical. Phones usually hold private and confidential information about an individual, often medical information, bank details or passwords and log-in details for various sites.

Hack computers or emails – Similar to phones, computers and email accounts can hold private and confidential information that someone might not want to share with others. It is unethical for a private investigator to hack computers or emails and it is also illegal for anyone to access data stored on a computer, according to the Computer Misuse Act, 1990.

Obtain bank or financial details – If a private investigator wants to access these details, they must ask for permission from the individual who it belongs to. Without permission, these details cannot be accessed by a private investigator, no matter how important they are to uncovering the truth for their clients.

Private investigators, also known as private detectives, work for private individuals and corporate organisations to find information. They may engage in different types of cases, finding legal, personal, or financial information; performing background checks; interviewing people; and engaging in covert surveillance activities.
