What is change of ownership?

The change of ownership of an activity is what is known as a "transferring a business". of the owner of the activity licence to the person or company buying the business. So, for example, if a company has a fully operational restaurant, which complies with current regulations and has a restaurant business licence, it can transfer its business licence to another person.

In order to make this transfer effective, the City Council requires all of the documentation required from both parties and always asks for a certificate of change of ownership signed by an engineer.  

What is the responsible opening declaration?

The responsible opening declaration is the simplest procedure available for opening a business.

This opening procedure consists of a application/form drawn up by the municipality where the interested party signs a series of points and takes responsibility that the activity he/she is opening complies with current regulations.

Moreover, the municipality calls for a Responsible model signed by an engineer. This document consists of 3 sheets describing the most important parts of the premises.

What does the Legalisation of Installations consist of?

Any modification of an existing installation or a new installation must be legalised as such. In some autonomous communities there is an administration that is in charge of registering the installations and giving the ok before being able to contract the supply.

In order to do this, a series of steps have had to be taken beforehand, such as the design, calculation and projection of the installation, o determine whether the installation requires a technical project or whether installation reports are sufficient.

What is an activity licence?

It is a legal document required to carry out the activity and is issued by the municipality directly to the company or user who owns the business. By means of this document, the administration has proof of the activity that is being carried out in its municipality, collects the taxes and ensures that all current regulations are complied with.

A business activity licence is obtained through the intervention of an engineerwhich classifies the activity according to needs, ensures compliance with all regulations and issues a certificate certifying that the premises are suitable for carrying out the activity.

What is an electricity project?

It is a document that is requested for the legalisation of low voltage electrical installations classified in the Low Voltage Regulation in its technical instruction BT-ITC-04.

It describes which installations need to be legalised by engineer and project and installations that do not require an electrical project and therefore the authorised installer himself can legalise the installation with his stamp and signature.

Requirements for Obtaining a Business Licence: A Detailed Guide.

Obtaining a business licence is a fundamental process in order to legally operate a business, and this process involves meeting a number of requirements that can vary significantly depending on the locality in which you wish to establish your business, as well as the specific type of activity you intend to carry out. En general terms, the first crucial step is to identify and understand the specific regulations of the municipality where the business is to be established.. Each municipality has the power to set its own regulations and rules, which makes this information of vital importance to avoid setbacks and delays during the application process.

One of the most common and generally mandatory requirements is the submission of a detailed technical project, prepared by a qualified professional, such as an architect or engineer.. This project must thoroughly detail the characteristics of the premises and the nature of the activity to be carried out there, including essential aspects such as the distribution of spaces, safety measures, accessibility facilities, and any other relevant technical features that ensure compliance with current regulations. In addition, it is highly likely that a prior inspection by the competent authorities will be required, who will verify that the premises strictly comply with the established health and safety regulations.

In addition to the above, it is absolutely essential to have all the necessary documentation to support the licence application. This documentation typically includes the applicant's National Identity Card (DNI), the lease contract for the premises where the activity will be carried out, as well as, in certain cases, complementary licences that are directly related to the planned activity, such as building permits for structural modifications to the premises or operating licences confirming the suitability of the premises for the type of activity planned. Proper preparation and submission of these documents will not only facilitate a more streamlined and efficient process, but will also significantly reduce the possibility of denials, which can be costly in terms of both time and resources..

Finally, it is advisable to consult a specialised advisor or an administrative manager with experience in obtaining activity licences.The advice is designed to make sure that all steps are being followed and all requirements are being met properly. This type of advice can be invaluable in navigating the process successfully and setting up the business without legal setbacks.

We help you to legalise your electrical installation

When do I have to legalise an electrical installation?

Whenever there is a change in the existing installation, you must apply for legalisation.. If, for example, you buy premises and need to switch on the electricity after a long period of time without supply, you will need to legalise the installation in exactly the same way as if you wanted to modify a fundamental characteristic of the premises.

 

You will also have to do this when you carry out a substantial renovation of an old installation.

 

You could even be asked directly by your local council or the regional administration.in the course of a municipal or regional process of regularisation and legalisation of electrical installations.

How to legalise an electrical installation?

In order to legalise an electrical installation, a series of procedures must be completed. The first is to obtain an installation certificate signed by an authorised installer.This must be submitted, together with other documentation, to the regional or local government department in charge of industry or energy.

 

Each project, certificate and other technical documentation that must accompany this procedure, must be signed by professionals authorised to do soThe following are generally low-voltage network installers, electricians with a special categorisation or technical and industrial engineers, depending on the administration.

Regulations and requirements to legalise an electrical installation.

The basic regulations on the legalisation of electrical installations are of a national nature, and are contained in the Royal Decree 842 of 2 August 2002, which approves the electrotechnical regulations for low voltage installations..

 

Apart from this regulation, which serves as a framework for the others, the development of the same and the specific regulation of the cases is contained in different regional and even municipal regulations.. Moreover, each electricity supply company has its own rules and regulations regarding the linking, so this information must also be managed in order to safely deal with the process of legalising an electrical installation.

Do you still have doubts about how to obtain your opening licence or legalise the electrical installation of your business premises?

At MARGAL Ingenieros we solve them for you.

The opening licence, also known as an activity licence, is an essential document in the business and commercial field. This is a compulsory legal permit that must be obtained by both natural and legal persons wishing to start a commercial, industrial or service activity in a specific premises or establishment.. This requirement aims to ensure that activities are carried out in a framework that complies with all applicable safety, health and environmental regulations.

The process of obtaining an opening licence is carried out through the town hall of the town where the establishment is located.. This entity is in charge of verifying that the premises comply with all legal and technical provisions necessary to operate in a safe and adequate manner. This includes the review of aspects such as the structural safety of the building, accessibility, noise regulations, and health and safety, among others.

Obtaining an opening licence is crucial for several reasons. Firstly, it ensures that the business complies with all regulations, which protects both the entrepreneur and the customers. Secondly, having this licence avoids legal sanctions and possible closure of the establishment by the authorities. In addition, it projects an image of seriousness and commitment to legality to potential customers and business partners.

The requirements for obtaining an opening licence may vary depending on the locality and the type of activity to be carried out.. However, a number of documents are usually required, such as plans of the premises, technical certificates, and in some cases, an activity project drawn up by a competent technician. An environmental impact report may also be required, depending on the nature of the activity.

In conclusion, the opening licence is not only an administrative procedure, but a fundamental step to guarantee that any economic activity is carried out in a safe, legal environment and in accordance with the regulations in force. For this reason, it is essential to be properly informed and to comply with all the requirements for obtaining it before starting any business activity..

This is the process by which the administration or the electricity company verifies that an electrical installation complies with the regulations before granting a new supply. This may occur after a previous disconnection or when changing the contracted power or the contract holder.

An authorised professional must issue the electrical installation certificate (boletín) and submit documents to the municipal or regional administration. After completing the formalities, the documentation is handed over to the utility company, which will connect the installation to its network.

In older installations, a refurbishment of the existing installation may be required prior to legalisation.

When we talk about a OCA in low voltageThe term "inspection" refers to a type of mandatory inspection carried out by an Authorised Control Body (ACO). This is a process regulated by technical regulations. which aims to verify and ensure that electrical installations comply with the safety requirements established by current legislation. These inspections are essential to guarantee the safety of people, the protection of property and the prevention of electricity-related accidents.

During an OCA inspection, various technical and safety aspects are checked, such as the correct installation of electrical systems, the quality of materials used, grounding, overvoltage protection, and the inspection of protective devices such as circuit breakers and fuses.

OCA inspections should be carried out at different times depending on the type of installation and the specific circumstances. The main cases are as follows:

  1. Initial inspectionThis is carried out before connection to the mains to ensure that the installation complies with the applicable regulations and standards.
  2. Periodic inspectionThis is carried out on a regular basis, usually every 5 years, to ensure that the installation continues to comply with safety requirements.
  3. Inspection for modification or extensionWhen significant changes are made to the installation, such as extensions or modifications, a new inspection is required.
  4. Inspection for deficienciesIf problems or deficiencies are detected in the installation, an inspection should be carried out to verify and correct these problems.
  5. Extraordinary inspectionIn exceptional cases, such as after an incident or accident related to the electrical installation, an additional inspection may be required.

In order to open a business, whether it is a company, shop or any other type of establishment, it is essential to comply with a series of legal requirements that ensure its correct operation and compliance with the regulations in force. One of the most important and mandatory steps in this process is to obtain an opening licence.. This licence is an official permit granted by the local council of the town where the business will be located, and certifies that the establishment complies with all the urban planning, safety, public health and environmental regulations necessary for its operation.

The process for obtaining an opening licence can vary depending on the type of business and location, but generally involves the submission of a series of documents demonstrating the viability of the project and compliance with local regulations. This documentation usually includes plans of the premises, technical reports and, in some cases, safety or environmental certificates.

In addition, if the premises where the business is to be set up require adaptation or renovation work, it is essential to obtain a building permit.. This licence must be applied for before any type of construction or structural alteration is started, and must be managed by a qualified technician, such as an architect or engineer.. This professional will be responsible for ensuring that the works comply with safety, accessibility and energy efficiency regulations, among others.

Failure to comply with these legal requirements can lead to penalties, fines and, in some cases, closure of the business. Therefore, it is advisable to be properly informed and, if necessary, to seek the advice of a professional specialised in legal and urban planning procedures to ensure that all permits are handled correctly and in a timely manner.

In short, the application for an opening licence and, if applicable, a building permit, is not only a mandatory requirement, but also a guarantee that the business will be able to operate within the legal framework and without future setbacks.

Before proceeding with a new electricity supply, after a prolonged interruption in the supply, when making a substantial change in the installation or when required by any administration for the purposes of regularisation of the installations.

In all these cases it is necessary to legalise the electrical installation.

It is a legal offence to start an economic activity in an establishment without having obtained the corresponding opening licence. If you do so, you may be visited by environmental inspectors or local police forces. This could result in the imposition of a substantial fine and even the sealing or closure of the businessThis would have extremely negative consequences.

It is of course possible to legalise an old electrical installation, but there are several things you should consider before proceeding. If the electrical installation was made after September 2003 and follows the regulations established at that time, you may be able to legalise it without the need for prior renovation.. This implies that the installation must meet the safety and energy efficiency standards required at the time.

However, if the installation is significantly older than this date, it is very likely that it will not meet current technical requirements, which could include safety standards, efficiency and compatibility with modern devices. In these cases, you may need to make some modifications or upgrades to ensure that the installation is safe and compliant with current regulations. These modifications could include changes to the electrical panel, upgrading the wiring to support modern electrical loads, or adding protective devices such as earth leakage circuit breakers..

In addition, it is important that you hire an authorised installer or a specialised company to carry out a detailed inspection of the installation. At MARGAL Ingenieros we can provide you with an accurate diagnosis and specific recommendations on the necessary upgrades.. Once the modifications have been made, the professional must issue an installation certificate or electrical bulletin that guarantees that the installation complies with current regulations. This document is essential in order to proceed with the legalisation before the competent authorities.

Remember that maintaining an electrical installation in good condition is not only a legal requirement, but also an essential safety measure to prevent risks such as short circuits, overloads or fires. In addition, an upgraded installation can contribute to greater energy efficiency, which could translate into savings on your electricity bills in the long run..

The difference between the Activity Licence and the Opening Licence lies in the purpose and timing of when each is required in the process of establishing a business or activity on physical premises.

The Activity Licence, also known as the Installation Licence, is the municipal authorisation obtained in order to start the works and carry out the necessary installations in a given premises.. This licence is essential when you want to adapt a space so that it complies with the legal and technical regulations for carrying out the planned activity. In other words, it focuses on the initial project and ensures that the conditions of the premises are suitable for the type of activity to be carried out. This stage is crucial to ensure that the modifications and adaptations of the space comply with safety, accessibility and urban planning regulations.

On the other hand, the Opening Licence, also known as Operating Licence, is the municipal authorisation that is granted once the works have been completed and the necessary installations have been carried out on the premises.. This licence officially permits the commencement of commercial or professional activity on the premises. In order to obtain it, it is necessary that the premises comply with the conditions established in the previously granted Activity Licence. In other words, it verifies that all the modifications proposed in the initial project have been carried out correctly and that the space is ready to be used in accordance with the regulations in force.

In a nutshell, the Activity Licence focuses on the feasibility of carrying out works and adaptations to the premises, while the Opening Licence focuses on the authorisation to start operating once these adaptations have been completed and verified.. Both licences are indispensable and complementary in the process of setting up a business or activity in physical premises.
