Arga Detectives Group will deal with the issue of prices and fees of private detectives in Spain as it is a subject much demanded by many.

Given the question of many of what private detectives in Spain charge the answer is that there is no fixed fee from a private detective to carry out their private research work in Spain, this is because each professional freely puts their rates according to the type of work they do, the place, the hours, the complexity, the technical and human means necessary to carry it out, the type of private detective, etc.

However, the Professional Association of Private Detectives of Spain establishes ostentatious guidelines or prices and we can see them we have them published in the rates section of the Arga website, you can go to it and look at it.

There are different Associations and Private Detective Colleges in Spain so prices may vary slightly by one or the other. Arga Detectives takes as a scale the guideline prices exposed by the Professional Association of Private Detectives of Spain to which we belong, however we will have to evaluate each particular case to see the specific problem that we face as well as the number of detectives necessary, the type of technology necessary to carry it correctly, the specific point where the private investigation is carried out.

It also varies according to the type of private research, such as whether it is business, work, family, computer, technological, etc. Having said that, we can therefore say that we need to value an endless element in order to provide an adequate budget.

Many will wonder who are the cheapest private detectives?

The truth is that there can be tremendous price differences between hiring in one particular detective office or another.

The amount does not have to be a fundamental element, but it is common sense to charge a minimum for the feasibility of research.

For example, the hours of private research in Spain range from 60 to 100 Euros the base price. If an office charges you well below, let’s take the example of 20 euros I distrusted.

We strongly discourage the hiring of cheap detectives in Spain.

This is because the decrease in money is likely to lead to a decrease in different aspects such as:

  • Inexperience of the professionals in charge of research.
  • Do not have qualified personnel to develop a specific research.
  • Lack of necessary technical means, etc.

In the face of this we recommend spending a little more and ensure success in private research with real professionals such as Arga Detectives who give it a fair price according to the market.

The truth is that sometimes it is better to pay a little more for something and make sure that your production is correct and not take unnecessary risks. An operational deployment for example carries minimal costs that must be supplemented to perform a successful run.

Arga Detectives gives an individualized budget to each client according to the interests of the same as well as the commitment on their part to carry out the matter quickly. It is important to ensure that legally qualified private detectives are hired as the client would not otherwise be able to present the report issued by them to the Courts of Justice.

It is necessary to have a great deal of experience on the part of the professional appointed in this regard who knows how to carry out a proper investigation and to collect evidence legitimately since they could subsequently be presented to the Courts of Justice.

Our work will have a major impact on the future of the matter concerning our client and will be a key element in making a decision on the matter.


Undoubtedly, all work carried out by a private detective can be presented in the courts with total value as long as it is done in accordance with the legal order.

Under the Private Security Act, any private detective’s actions in his private investigation work shall be governed by 3 principles:

  • Proportionality.
  • Fitness.
  • Need.

Under these three premises all performance of the private detective will move and all his performances must be adhered to. If the judge or court sees the slightest indication that any right to investigate has been violated, it will immediately throw away all the private detective’s work and will not be taken into consideration under any circumstances. In addition, the detective may be involved in any criminal offence with the corresponding civil liability and the security measure of separation of his duties.

That is why, when paying for a private detective in Spain, it is extremely important to hire a professional who knows the legal system in a complete way and knows how to act within the law at all times. This is because the private detective is always in his private research work on the border with the right to privacy of the investigated.

There is sometimes a bad view of the private detective, as this one is sometimes classified as a kind of spy. The vary from reality, since the concept of spying has nothing to do with research. Private detectives have an apparent and clear social function by developing a function of social interest such as the discovery of truth.

The private detective’s work ends only after judicial ratification of the private investigation and not after the completion of the private investigation as such. Otherwise, it could be said that the private investigation does not end until ratification occurs.

The investigation process would therefore be only one more phase of the entire private detective’s work phase during his duties.

Therefore, the judicial ratification phase is as important as any other phase of the investigation process. It is extremely important to have experience in ratification before the courts.

This element is well known by  Arga Detectives so it lectures all its professionals in the field to develop impeccable work.

That said, it’s clear that the work of a private detective is not only based on wearing a trench coat and a hat and conducting surveillance and follow-ups.

A private detective must have a comprehensive background in all his work of having professionals.

The private detective must be a scholar of the word, able to convey to the judge the correct idea of everything that has been done in the private investigation.

The importance in the drafting of the report is extremely important, hence the Arga Group making all the reports thoroughly.

Hence, there is a need for high training in the writing of reports by the private detective’s work and we should not downplay this phase of embodying the evidence and development of research.

As we have said on countless occasions, we fully discourage the hiring of cheap private detectives.

This is expandable to all professions in every society, whether you hire a doctor, a psychologist, a teacher, a waiter or any other professional.

It is therefore common sense to say this, and prefer to spend the average price on any professional that guarantees results.

If you want to continue the search in hiring cheap private detectives, from this point you will be aware of the possible consequences in this regard.

Arga Detectives Group will provide you with a budget according to the economy of each pocket after studying the details of your case and all the circumstances surrounding it



After the phone call to our private detective office in Madrid the first thing we usually do is make an appointment for the client to be personified in any of our units throughout the Spanish territory. We need to know what their concerns and interests are and what problem we are facing.

We have to get an idea of different points to be able to emit some prices according. We need to assess issues of complexity and specialization such as:

  • Duration of the investigation. It’s not the same, a three-hour private investigation as a 35-hour investigation. The time in the longer investigation will be charged more economically.
  • Time slot of the same and day. We need to distinguish whether the investigation takes place day or night and whether it takes place during the week or weekend or public holiday.
  • Place of realization. You have to assess the kilometers necessary to carry it out.
  • Type of research according to complexity. There is more complex research than others such as a follow-up at a large airport like Madrid that there are many people.
  • Necessary preparation of the private detective to carry it out. There is research that requires great preparation on the part of the professional.
  • Use of necessary technical means. There are for example traces that a large displacement motorcycle is required.

We often know when an investigation begins, but we don’t know when it’s going to be completed. So it can be the case that we follow someone who is driving or goes by train and leaves their city and goes to the least thoughtful place.

The private detective’s work is unpredictable at times and we can’t always know a priori all the details in every investigation. However, in the face of such events, the private detective agency will call the client and ask him what his decision is.

At no time can the customer take a surprise about the hours he is intended to check in by our office. Before we continue we will contact it and communicate the reality that is being given to give us the approval of whether we continue or terminate the service.

Transparency is a crucial factor between Dispatch – Client, and being informed at all times of the course of the investigation is part of it.
