Electrical certificate · Marratxí
Have you been asked for the boletín in Marratxí to connect the electricity, increase the power or legalise a renovation after a sale? We are Joaquín and Juan, a low-voltage authorised installation company since 1998: we come out to your property in Pòrtol, Sa Cabaneta, Es Pla de na Tesa or Es Pont d'Inca, inspect the installation, issue the Electrical Installation Certificate (CIE) and register it with the Govern de les Illes Balears. Paperwork in order and no nasty surprises.
Always inspected first · Registration with the Govern included · We speak Spanish, English and German
These are the four cases we get called about most:
In plain words
The boletín is what everyone here calls the Electrical Installation Certificate (CIE): the document in which a low-voltage authorised installation company declares, and signs, that the installation complies with the Spanish Low Voltage Regulation. In Marratxí it comes up more than elsewhere for two very specific reasons: a lot of property is bought and sold here, and the detached houses built in the eighties and nineties run short of power as soon as you add air conditioning, an induction hob, a pool or a car charger.
It is not just paperwork: whoever signs it takes responsibility for what they certify. That is why it cannot be issued without seeing the installation, and why a house with an old consumer unit or without proper earthing cannot be certified as it stands.
Once issued, we register it on the electronic office of the Govern de les Illes Balears. That is where the official record sits, and where your electricity company looks it up to connect your supply or change your terms.
When you need it
If you are in one of these, call us and we will tell you exactly what your case needs.
A new home, a unit on the Marratxí industrial estate or a house that has been without supply for years. Without the certificate, the company will not connect it.
You have installed air conditioning, a heat pump, an induction hob or a car charger and the breakers keep tripping. To increase the power you may be asked for the certificate: on low-voltage contracts more than 20 years old the distributor checks the installation and, if it does not comply, requires it to be brought up to standard and the certificate to be submitted (art. 38.7 of the regulation approved by Royal Decree 88/2026).
A sale, an inheritance or a rental where the name on the electricity contract changes. In Marratxí we are asked about this a lot, given how much property changes hands here. On its own it does not require a new certificate: on low-voltage contracts more than 20 years old the distributor cannot ask for one if neither the technical conditions nor the access tariff change (art. 39.6 of the regulation approved by Royal Decree 88/2026). If the power or the installation changes with it, you may be asked for one.
When the consumer unit is replaced, circuits are added or the home installation is redone, the certificate records how it ends up.
The electrical installation of a swimming pool has its own requirements in the regulation. It is one of the things we most often have to correct in older properties.
Charging points are legalised under ITC-BT-52, with their own certificate. We handle it all with the same team.
How we work
We come out, inspect it and check the consumer unit, the protective devices and the earthing. We tell you there and then whether it is in order or what is missing.
If something does not comply, we give you a fixed quote before touching anything. If it is fine, we skip this step and you do not pay for it.
We sign the certificate and register it on the Govern electronic office. We hand it to you to take to your electricity company.
So there is no confusion
This is the most common mix-up and worth clearing up, because they are different documents, for different procedures and at different prices:
It states that your installation complies with the regulation. It is signed by an authorised installation company and is used to contract or modify the electricity: connection, power, renovation.
It is the A-to-G label that rates what the property consumes, and it is required in order to sell or rent. It is explained on our page about the energy performance certificate in Mallorca.
We do both, so if you are not sure which one you are being asked for, call us and we will tell you in two minutes — before you pay for the wrong one.
Frequently asked questions
It is the Electrical Installation Certificate (CIE), the official document in which a low-voltage authorised installation company declares that the installation complies with the Spanish Low Voltage Regulation. Everyone here calls it the boletín, and it is what your electricity company asks for in order to contract or modify the supply. The governing regulation is the Spanish REBT (Royal Decree 842/2002). Its ITC-BT-05 also sets periodic inspections every 5 years for installations that required an initial inspection, and every 10 years for the common areas of residential buildings with more than 100 kW installed. In Marratxi that mostly affects the communities in Es Pla de na Tesa and Es Pont d'Inca.
The usual cases are connecting the electricity in a home or business premises, increasing the contracted power and a refurbishment that modifies the installation. Also when legalising a swimming pool or an electric-car charging point. A change of holder does not by itself require a new CIE: Royal Decree 88/2026 prevents the distributor requesting one for low-voltage contracts over 20 years old when neither the technical conditions nor the access tariff change (art. 39.6 of its regulation). Nor does age on its own: on those contracts the distributor checks the installation when the power is increased and requires the certificate if it does not comply (art. 38.7).
No. The certificate is signed by an authorised installation company that takes responsibility for what it certifies, so the installation has to be seen and checked first. If something does not comply, we tell you what needs correcting and give you a quote before touching anything.
Only an installation company qualified in low voltage, with its authorised installer. JSL Mallorca is one: we issue the certificate and register it on the electronic office of the Govern de les Illes Balears, where the official record is kept.
No, they are two different documents for two different things. The boletín is about the electrical installation and is used to contract or modify the electricity supply. The energy performance certificate rates the building's consumption with a letter from A to G and is required in order to sell or rent. We do both, but they are not interchangeable.
We tell you straight, with a quote: what is missing, what has to be changed and what it costs. In older houses it is usually the consumer unit, the earthing or the residual current devices. Once corrected, we issue the certificate and register it. We never certify an installation that is not in proper condition. The REBT (ITC-BT-05) grades the defects found in an inspection as very serious, serious or minor, and it matters: with a very serious defect, a new installation cannot be put into service until it is put right and, if it is already in service, the inspection body issues a negative certificate and sends it straight to the competent department of the Govern. That is why in Marratxi we look at the consumer unit and the earthing first, which is where they show up in houses built before 2002.
All of it: Pòrtol, Sa Cabaneta, Es Pla de na Tesa, Es Pont d'Inca, Es Figueral, Sa Cabana, Cas Capità, Els Caülls and Marratxinet, plus the residential areas and the industrial estate. We look after you in Spanish, English and German. You can see our work and customer reviews on the JSL Google Maps listing →.
