Do you have questions?

Here we solve it all

Does the change of marketer have any cost?

The change of marketer has no cost. Although there is the possibility that your former marketer apply penalties for the breach of the contracting time, so it is advisable to consult the marketer if there is a penalty.

It is important that you do not confuse signing up with changing trades. The highs are for when there is no supply.

Will I lose power during the change?

No. At no time or under any circumstances you will be without supply due to the change of marketer.

Is it necessary to make a change in my installation to change my sales company?

You do not need to make any changes to your meter or your installation. The change is administrative, so technically everything remains the same.

Could I go back to my company in case I change my mind?

Of course, you are free to leave since there is no commitment to stay. If, once the change is made, you are not satisfied with our services, we will provide you with everything possible to complete the return process..

Do we necessarily have to change the electricity company?

The move to the liberalizes market necessarily means a change of company, but you can contract with a trading company of the same group as your current distribution company.

Will I have to continue paying a receipt to my previous company?

No. As of the date that the supply is with us, your previous company should not charge you any receipt with a later date. Although it is true that, although the collection is subsequent to the date of change, it may belong to a billing period prior to the date of change.

What is the difference between a distributor and a marketer?

To know how the electric sector works, let's start from the beginning.

The producers are responsible for producing energy. In our country there are different production plants such as:

  • Conventional thermal power plants
  • Nuclear power plants
  • Or alternative energies such as wind farms, photovoltaic power plants.

- The carriers are responsible for the transport of energy in high voltage, in our country is the Electrical Network of Spain (REE).

- The distributors, remain regulated by the State, and are responsible for maintenance and the different areas of the country

And finally here we enter the marketers like Lumisa, who are in charge of buying the energy and billing it to their consumers using the distribution networks.

Does changing power have a cost? 

Yes. The distributor is responsible for the collection, and we the marketer manage it. If you ask for a change of power you will get the detailed costs of this in the next invoice that you generate after having requested it. 

How to make the change of marketer?

The light commercialization change is a fast and totally free management.This is carried out when we want to go to another company because they offer better prices or better services. In addition, in no time you will not be without light during the management of the change.

If you have decided to contract with Lumisa, we will briefly explain the steps to follow. If you contract through the Customer Service telephone or website you should follow the following procedure.

1. To make the change to Lumisa, you must provide the following documentation via email or fax at or 931 815 993 or Whatsapp 633 33 38 39.

  • In the case of a company, CIF of the company 
  • or ID of the owner or administrator.
  • Last electricity bill 
  • Photocopy of the bank account number.

2. Once we receive the documentation, we will proceed to send the contract to the shipping address.

3. A copy must be kept and resend by postal mail.

4. Once we receive the contract, we will proceed to make the change. The change may take between 15 or 20 days depending on the distributor.

5. A final liquidation invoice will come from the previous merchandiser.

6. Lumisa's first invoice will close the billing cycle. From the second invoice will begin the natural billing cycle.

So you do not have to worry about anything since we will handle the procedures quickly and efficiently.

What is a connection management?

The connection management is an installation that connects the distribution network with a new supply. The application can be made through the Distributor of your area, or instead, from Lumisa we can process it.


If you want to inform yourself about it, do not hesitate to visit our article about the steps to follow and the cost of it!

Who is responsible for registering new supplies?

The distributor is responsible for supplying a supply point without service, that is, it is responsible for reviewing all the technical documentation issued by the installation company, ensuring the safety of the supply point and placing the ICP and / or the relevant counter.

They are also the ones that receive the cost that you have to pay for accessing the network. This cost is regulated by the State.

See cost section.

Does the registration of a supply point have a cost?

Registering an electricity supply or reactivating one that has not been used for more than 3 years has a cost regulated in Royal Decree 1995/2000 of December 1 that the distributor will charge you through Lumisa:

  • Access rights: it is paid when contracting a new supply or by increasing the power of an existing supply with an amount of 19,70/kW.
  • Extension rights: it is paid when using the infrastructure of the distribution company in the case of new supplies, when the power contracted increases or if the supply point has not been used for more than 3 years with an amount of 17.37€ for each kW.
  • Engagement rights: it is paid at the moment in which the electrical installation is connected to the supply network with an amount of ​9.04€.
  • Verification rights: paid when carrying out the installation review with an amount of 8.01€. 
  • Guarantee deposit: according to what is established in article 79 of Royal Decree 1955/2000, it is the amount to be delivered, at the time of contracting, for an amount equal to the monthly theoretical turnover corresponding to fifty hours of use of the contracted power .

Is it necessary to provide technical documentation?

To register new supplies, it is necessary to provide technical documentation. In this case it can be a CIE (Electrical Installation Certificate) or a BRIE (Recognition Bulletin) issued by the installation company.

The CIE can be replaced by the BRIE when it is a second occupation and the installation meets the following requirements:

  • Power less than or equal to 20 kW.
  • No change of activity.
  • It is not public concurrence.
  • The withdrawal from the previous contract was less than a year ago.

Who can issue me the technical documentation?

An installation company or an authorized installer can issue you the technical documentation that certifies that the installation is correct for the discharge of the supply.

How long does it take to register? 

As soon as we have all the required documentation, the distributor takes 5 days to activate a low voltage supply point.

What is the difference between registering a supply and making a change in sales?

When we talk about registering, we refer to supplying a point where previously there was no light. In this case, you have to process the connection file directly with the distributor of your area to obtain the CUPS.

On the other hand, when we talk about a change of marketer, is when we already have electricity and is contracted with a company, but we want to go to another because they offer us better services or more competent prices, or because we make a change of owner and prefer a different marketer.

In we explain it in more detail.

What is the telemanagement counter?

Telemanagement is an intelligent reader of electricity consumption that can be replaced by traditional electric meters. Its advantages, among others, are that it can read consumption remotely, make real readings, faster incidents.

The Royal Decree 1110/20017, Order ITC 3860/2007 and IET 290/2012 which obliges the distribution companies to replace the current meters, with power less than or equal to 15 kW for meters with telemanagement capacity before 2018.

How can I read my meter reading?

To read your meter you will have to follow some steps:

1. It is necessary to identify your accountant. For that, you have to find the counter number that appears on your invoices.

2. You have to identify the access rate to know how many reading periods you have to read:

  • 2.0A - one period
  • 2.1A - a period
  • 2.0DHA - two periods
  • 2.1DHA - two periods
  • 3.0A - three periods

How can I contribute my meter reading?

After reading your meter reading, you can call us at 900 811 473 or write to to provide us with the reading. We will need to identify your supply point, so it is also necessary that you indicate the CUPS number, universal code of the supply point.

What is the cost of meter rental?

The cost of renting equipment is set by the Ministry of Energy, Tourism and Digital Agenda, which is regulated by Order IET / 1491/2013, of August 1, which reviews the electric power access toll.

Therefore, the marketer will charge the rental of equipment, although it really is a payment that is paid to the distributor because it is responsible for the operation and maintenance of the same.

These prices will depend not only on the price of the equipment but also on the costs associated with its installation and maintenance. Therefore, the average cost for renting domestic light meters is € 0.81 for single-phase meters with time discrimination and with the possibility of telemanagement. And € 1.36 for three-phase meters with time discrimination and with the possibility of telemanagement.

Where can I find the schedule of each electricity tariff? 

As established in Order ITC / 3801/2008 of December 26, the schedule is regulated as follows:

- Rates without time discrimination: the same price throughout the day.

- Rates with time discrimination: different price according to time zone. There are three schedules according to the time of day:

  • Tip: It is the time period with the highest price since it is the most requested.
  • Valle: The period with the lowest price.
  • Llano: The hour period with an intermediate price.

Time discrimination also varies slightly according to the time of year and the power of the tariff.

- Rates 2.0 DHA (less than 10 kW) and 2.1 DHA (between 10 kW and 15 kW):

  • In summer: Valley (23h-13h) Punta (13h-23h).
  • In winter: Valle (22h-13h) Punta (13h-22h).

- In 3.0 A (from 15 kW):

  • In summer: Valley (23h-9h), Punta (12h-15h), Llano (9h-12h / 15h-23h).
  • In winter: Valley (1h-9h), Punta (18h-22h), Llano (9h-18h / 22h-1h).

In an article "What is the most suitable power for me?" that we explain in detail.

What is the CUPS code for?

Apart from being something like our fingerprint to identify the installation and where the supply resides, it is necessary to carry out any management with the distributors, distributors, public administration, etc.

What is the CUPS code?

It is the Universal Code of the Supply Point. It is a unique code for each energy supply (electric / gas) that identifies it. Start with the sequence ES followed by 20 digits.

What happens if I do not pay my electricity bill in the term?

In most cases the payment of electricity is usually made by direct debit. In this case, if the payment is made late, the marketer will proceed to notify payment of the same by mail or email within a period of 7 working days.

That is why if the payment of said invoice was not made within the term, the markerter could make a commission for non-payment management. It is a commission that, for each fee that is unpaid, will be made at the moment in which the first written claim is generated requesting its regularization.

How can I make a change of owner? 

In order to make a change of ownership, keep in mind that:

  • The change is always requested by the new owner.
  • The new owner becomes responsible for the invoices.
  • The amount of the first is calculated pro rata.
  • We do not charge to change the owner, but in some cases you may have to pay your distribution company.

The request to change the holder can be processed online in a very fast and simple way through the web. You only need to have on hand a recent invoice, the bank account and the DNI of the new owner.

If you want to discuss it in more detail, we have an article in our blog  "Make a change of holder of the light" with the step by step to follow.

Who is Logalty?

Logalty is the third trusted party that intervenes between the parties to a contract or online notification to guarantee and safeguard, in a neutral and independent manner, all the processes generated in the electronic transactions carried out. In addition to guarantee the integrity of the process without taking into account, the content of the documents is secured before a notary.

Can I make arrangements such as changing the owner or marketer, among others, by phone or e-mail? 

Yes. We advise you to do the online procedures because it is the fastest way and you can attach the online documentation directly, but if you prefer, you can also do it through our phone number 900 811 473 or our e-mail

Here you have all the details of what we are going to need that you give us to do it .

When do I need to change power?

If you never "jump the leads" you probably have room to lower the power; If, on the other hand, they skip you often, you are already at your limit. In the event that you add new appliances or increase the use, you will probably have to contact your electricity company to discuss an increase in power.

How do I know that the contracted power is inadequate?

The power you need will be determined by several factors. A very intuitive way to know if our power is inadequate is the following:

1. Turn on all the appliances in your house at once. If the leads do not jump, it means that surely you have a power over what you need and have some margin to decrease it.

2. If in the daily use of your electrical appliances often jump the house leads, is that the power you are using you fall short, and you will have to expand it to enjoy more comfort.

See our article "What is the most suitable power for me?" that will solve your doubts about this topic. 

How to request a change of power?

If you want to modify the electric power, you can contact us by email requesting a power change request form. Once it is filled out and signed, it will be resubmitted for the start of the management.

In the same way, you have the option to do it online, conveniently and quickly through the web.

It will only be necessary that you have at hand:

  • Address of the owner of the electricity supply.
  • Personal data of the administrator.
  • Current and new contracted power.
  • CUPS, which appears on any invoice.

When is the new electric power activated?

The power change is made in a processing period of 15 to 20 business days. Once the request to change the power has been received by the marketing company, it will duly inform the distributor of the area. Which will send an authorized technician in charge of regulating the ICP to establish the new power and check its operation.

How much does it cost to change the contracted power?

If it is a reduction of the power you will have to pay a small cost of € 9.04 plus VAT due to the entitlement rights.

On the other hand, if it is an increase in contracted capacity, the expense will be higher since access rights must be paid with an amount of € 19.70 plus VAT per kW requested. As well as the extension fee with an amount of €  17.37x kW and € 9.04 plus VAT due to the entitlement rights.

If you want to know more about this, here is the article "Lower the power to save? Yes or no?".

Can I change the power as many times as I want?

No, the Distributor is only obliged to process a power change once a year. Therefore, if in less than one year the change is requested again, it will be denied and they will have to wait for the indicated time to make a new modification.

What can I do if I run out of light? 

In this case, we recommend that you verify that you are not the only point of supply without service. If there are more neighbors without service, you have to call the distribution telephone number to communicate the incident, since in this case the fault is in the external network.

If you are the only one affected, it means that the fault is inside your facilities. In this case, you have to call an electrician for repair and distribution without the person in charge of the incident.

Why is a file opened at a point of supply?

It is due to an anomaly detected in the meter, that is, it stops recording the kW consumption or part of it. In order to clarify what happens the company opens the file to go to check the measurement equipment and see if it is due to technical failure or possible fraud.

What does it mean to normalize the supply?

Once the file has been processed, if fraud has been found, the corresponding fine will have to be paid and then the supply will be standardized in accordance with current legal regulations.

Normally, the meter is paid as rental of measure month by month, if it is that way, the distribution company must proceed to normalization to update it.

Otherwise, if you have an own accountant, the work necessary for this will be carried out by the user, and the distributor must be notified once it has been finalized so that the latter can verify it.

When is everything already in order how do I restore the supply?

You have to go to your marketer who will inform you how to pay the amount that corresponds to the amount of kW you received in the first letter. When paying, will proceed to restore the electricity supply normally.

What should I do if the power supply is interrupted with the new meter?

If once activated the power control by your Distributor "leapt" the leads, it is because the power demanded exceeds the power currently contracted. And therefore the new device would interrupt temporarily the power supply.

In order to restore it immediately you must follow a series of steps:

1. Disconnect any of the appliances, since the contracted power limits the amount of appliances that we can connect at the same time.

2. Open the electrical panel and check that all switches are raised, including the general.

3. If one is down, it is possible that you have some problem in your installation. In this case, we recommend that you consult with an authorized installer.

4. Turn down the main switch and wait for 3 seconds. After this time, upload it again.

5. In case the power supply is not restored, wait a few minutes and repeat the previous steps. The normal thing is that you have electricity again. If this is not the case, it may be a programmed cut or a fault.

If once you have made these simple steps, you continue to lose power often, you most likely have to increase the power contracted by contacting your dealer. Or it may also be due to a fault in your installation, so you should contact an authorized installer.

How can I know what type of rate I have contracted now?
