Factors Involved in Private Investigator Cost: Retainers, Hourly Fees, and Flat-Rate Costs

Private Investigator Cost Calculator

This post examines four different payment structures Private Investigators use and how much it costs to hire a Private Investigator to investigate six popular case types.

How Much Does a Private

Across all cases, the cost of hiring a Private Investigator in the U.K. ranges from £40 - 200£ per hour.Trustworthy, Affordable, Reliable Private Detective And Investigation Services, as the largest national network of licensed Private Investigators, charges between £69/hour and £79/hour.

Retainers for most agencies range from £500-£2800, depending on the type of case. Trustworthy, Affordable, Reliable Private Detective And Investigation Services' average case cost works out as 7 hours at £79/hour, or £553.00 with no retainer (we don't charge one). Surveillance cases will run higher, while research cases will run lower, depending on the circumstances.

How much a Private Investigator cost depends on the work you want to be done and the case's location. If you wish to hire a private detective to find records or property, follow someone, investigate infidelity, or find a lost relative, you'll need to know how Investigators charge and what the likely cost will be for your case.

Common Causes and Their Costs

We've handled many cases here at Trustworthy, Affordable, Reliable Private Detective And Investigation Services. To help you understand how much you can expect to pay for a Private Investigator's services in handling common cases, we've compiled some typical case costs based on our hourly rate of £79-£99 (we charge hourly, with a small setup fee - we do not charge a retainer). We've also included some general notes on different cases and a rough guide to prices from other agencies to help you compare our methods to the rest of the industry.

Locating Someone

Typical case length:4-8 hours

Typical cost: £316 - £632

Finding someone can include process serving, a skip trace for a court matter, locating a runaway child, or just seeing an old friend.

A locate case can vary significantly in cost. Often 4-8 hours or more of work is not atypical for this case. This will fluctuate depending on how much information you have on the person you're searching for and other factors affecting the difficulty of the case.

Most London Investigators will use the hourly rate payment structure to locate someone and charge you for expenses. (like

Surveillance, Infidelity, and Following People

Typical case length:4-18 hours

Typical cost:£316 - £1242

Each case is different. Surveillance cases can be unpredictable, but generally speaking, the more information about the person of interest's (POI's) habits and personal life that the Investigator has, the faster they can investigate.

Most agencies will charge a retainer for cases like this that tend to range anywhere from £1,000 - £5,000, with an hourly rate charged against that retainer. At Trustworthy, Affordable, Reliable Private Detective And Investigation Services, we simply charge an hourly rate (discount for more prolonged cases). We have a whole post that breaks down what you can expect to be billed to have someone followed.

Locating Birth Parents or Adopted Children

Typical case length:2-10 hours

Typical cost:£158 - £790

The cost of a case of this nature depends on a couple of critical factors: how long it has been since the last contact and the availability of essential records (like birth certificates). If the case is recent, a quick digital investigation can locate someone in a matter of an hour or so. On the other hand, if the person you're looking for was born some time ago and you have little information, the case can run a little longer.

Because these cases can be lengthy and complex, most agencies will charge a retainer usually ranging from £5,000-£10,000 and then charge hourly against this sum.

Again, at Trustworthy, Affordable, Reliable Private Detective And Investigation Services, we will charge our hourly rate, which is discounted for more prolonged cases. To help get your case started, you can also look at our online investigative guide.

In-Depth Background Checks and Research

Typical case length:4-8 hours

Typical cost:£316 - £632

The cost of a proper, in-depth background check from a Private Investigator depends primarily on what you're looking for and what you have to go on. If you're looking for things like phone records, court records, or other detailed information, these will affect the final price of the case. The more detail you're looking for and the less information you have to get started, the more likely your case will cost.

You may be wondering why this price is higher than the online search services you might have found on the web. A background check by a Private Investigator costs more because, rather than quickly combing over public records and outdated databases, you'll have an experienced human with information that an average civilian can't access working on your case. Of course, there are better ways to perform a free background check, but if the background check is essential, you should use a Private Investigator.

Getting Phone Records or Tracing Cell Phones

Typical case length: -

Typical cost:-

Cell phone records used to be available until 2006 for a nominal sum by licensed Investigators - but the law changed, and now different methods are required.

These days, Investigators can use tools, guesswork, and human intelligence to determine what carrier a phone number is on and to whom it is registered. They can also use other surveillance and investigation methods to investigate who someone might be contacting (the preferred method).

Tracking a Cell Phone

Typical case length: -

Typical cost:-

It's illegal for a Private Investigator to track someone's phone without the owner's permission of the phone. If you need to track someone's phone, we have an article covering surveillance instead. Generally speaking, management isn't on shaky legal ground like cell phone tracking, and pictures make much better evidence that can be used in court if taken correctly.

How to Hire a Private Investigator

Ready to Hire a Private Investigator? Here are a few things you should know, whether you hire a Private Investigator through Trustworthy, Affordable, Reliable Private Detective And Investigation Services or not.

  1. Check Their Reviews or Get a Recommendation. There are unscrupulous Investigators out there - and even fake ones! (You can check Trustworthy, Affordable, Reliable Private Detective And Investigation Services'reviews on Trustpilot.)
  2. Check their license. Some research cases do not require a licensed Investigator - but if the issue is on location or requires experience and specialized database access, you should make sure they are approved they will be operating throughout the case. Here's a handy guide on licensinginformation for each city.
  3. Ask about confidentiality and security. Make sure that you are comfortable with their procedures, including how they plan to communicate with you throughout the case, how they intend to send you their final report, and what their skills are with undercover work if they are going to be insensitive, covert situations.
  4. Ask about their experience and training. Private Investigators that operate illegally or unethically can get you in trouble or harm your case. Ask them about using GPS (Global Positioning System, an accurate worldwide navigational and surveying facility based on the reception of signals from an array of orbiting satellites.), trackers, hacking into cell phones, and techniques. These three techniques are all legally restricted and prohibited in most circumstances.
  5. Ask about insurance. Many cities have insurance requirements for licensed Investigators. Insurance isn't necessary for every case, but if it is, you should ask about it and make sure that they have the required coverage.
  6. A good Private Investigator will discuss your expectations before money changes hands. Sometimes, it is impossible to achieve all your goals, and you should be aware of what's possible before the case begins.

Typical Private Investigator Fees

Private Investigators will typically charge for their work using a combination of one of these four common pricing structures. For example, it's not uncommon to have a retainer combined with an hourly rate or to have expenses included in an hourly rate - be sure to confirm this with your Investigator before you begin your case.

Note: Trustworthy, Affordable, Reliable Private Detective And Investigation Services charge from £69-£79 an hour for our Private Investigator's services, excluding expenses, with no retainer. This fee includes dedicated case support to help you get what you need and extensively vetted Investigators.

Hourly Rates

Generally, hourly rates for Private Investigators range between £40-£200 nationwide. However, hourly rates change depending on your location, the Investigator or agency you hire, the difficulty of the case, whether you'll have more than one Investigator on the subject, and even the time of year.

Most Investigators and agencies (including Trustworthy, Affordable, Reliable Private Detective And Investigation Services ) will adjust their hourly rate based on factors like overall hours purchased, the price of gas, and expected risks to the Investigator's safety. Most agencies (like Trustworthy, Affordable, Reliable Private Detective And Investigation Services ) reduce their price per hour if you hire them for many hours. It is important since investigations involving tactics like surveillance can take a significant time.

Note: Most hourly rates usually don't include any extra fees that an Investigator might incur but Trustworthy, Affordable, Reliable Private Detective And Investigation Services will cover average expenses a Private Investigator may charge for (outlined later in this post).

Flat Fees and Rates

For straightforwardly complete services, a Private Investigator or agency may charge a flat fee. Flat fees are simply a fixed price for the service's completion. A flat-rate pricing structure should also cover any other expense to complete your case in the private investigation industry. The sorts of issues that often attract a flat fee include:

  • Background Checks
  • GPS (Global Positioning System, an accurate worldwide navigational and surveying facility based on the reception of signals from an array of orbiting satellites.) Monitoring
  • License Plate Searches
  • Confirming a Cell Phone Number
  • Employment Checks


Retainers can vary from £1,000 to over £5,000 per case, depending on the Investigator's or agency's policy and the work you need to be completed.

Some Investigators will charge against your retainer and refund anything they don't use, while others will keep the total amount, whether or not they use all of it. If the services that the Private Investigator agreed to provide for you exceed the cost of your retainer, or the investigation incurs expenses exceeding the value of the retainer, you'll most likely be charged for them.

At Trustworthy, Affordable, Reliable Private Detective And Investigation Services, we do not charge a retainer - - just a one-time £50 processing fee to get your case started, and then charge you at an hourly rate after that.


About charges, talk to your investigator. Some of the ordinary costs include:

  • The client pays tolls.
  • Air Fare - If your Investigator has to fly to your job site, you should expect to foot the bill for the plane tickets.
  • Hotel Fees - If your job requires an Investigator to spend the evening in a hotel, you should expect to cover their room.
  • Court Appearances - If your Investigator has to testify, they usually will charge for their time in court, either with a flat fee or hourly rate.
  • Administrative Costs - Some Investigators will charge for things like mailing evidence, faxing, and administrative staff. Typically, this ranges from£50-£150.
  • Database Fees- if your Investigator uses private databases in their search, they may also charge you for any fees they had to pay for the use of the database.

You must get an itemized invoice at the end of your investigation to ensure that you can account for all of the expenses your Investigator may have changed.

Hopefully, this guide has given you a good idea of what your case is likely to cost. If you're still not sure, that's OK - the cost of each case tends to be determined on a sound, case-by-case basis. Individual circumstances, the information is given, and other specifics have a significant impact on the price of any investigation. The best thing to do is talk to a professional and see what they say. You can get a free case estimate right here, anytime. ,anytime.

If you are considering retaining the services of a Private Investigator, you may want to know some background information regarding these individuals. Here are a few frequently asked questions about Private investigator and their answers.

A detective/ Private Investigator is someone who investigates to uncover specific evidence. A Private Investigator may have to undergo thorough training and be licensed by a licensing authority. Many retired police officers or military personnel pursue this profession.

Private Investigators are retained in all sorts of cases. They are commonly associated with family law cases, including child custody, divorce, adultery, and child support cases. They are also retained in accident cases, including for the use of accident reconstruction and insurance investigations. Additionally, may hire them to help locate assets, provide forensic accounting services, or complete background checks. This is just a tiny sample of the cases they work on during a routine week.

Anyone can hire a Private Investigator. However, law firms, businesses, insurance companies, and private citizens may retain the services of such professionals.

A Private Investigator may offer a variety of services to their clients. By hiring a Private Investigator, law firms may gather information about parties or witnesses in civil or criminal cases. Insurance companies often retain their services to investigate suspicious claims. Private parties may hire Private Investigators to find missing people, complete surveillance on spouses, or unearth hidden assets to enforce a judgment. Fieldwork consists of conducting interviews and completing surveillance work. Once finished, they may create detailed reports that describe their findings and testify in court.

In many cases, Private Investigators charge an hourly fee based on the complexity of the case, the location, and other factors. Some services may be available for a flat price, such as a background or record check. However, many Private Investigators will ask for an upfront retainer before they agree to take the case. You may also have to pay for out-of-pocket expenses that Private Investigators expend to complete the service, such as mileage, airline charges, copying charges, long-distance telephone call charges, and photo printing charges.

Before you sign a retainer agreement with a specific Private Investigator, there are several steps that you should take to execute due diligence. For example, you should request references for the Private Investigator, including past clients. Additionally, ask for the Investigator’s license number if applicable and check with the licensing board about any particular complaints that have been lodged against them.

Hiring a Private Investigator should not be made as a rash decision. Instead, research the Private Investigator whom you are interested in hiring. Complete a brief phone interview with them and request an initial consultation. Many Private Investigators do not charge for such a consultation. You may need to ask them several questions to learn about everything important to you. Be sure that you ask specifically about how they charge and which costs are built into this estimate. Ask for an approximation of what the complete service will cost you and whether an upfront retainer is required. Ask for a written retainer agreement before you pay the Investigator. Additionally, ask that the Investigator provide you with an itemized bill and services accounting.
