If you are buying a property in Málaga and someone — your lawyer, your gestor, the notary, the seller’s agent — has mentioned a “boletín eléctrico” or “CIE”, you are now learning a piece of Spanish bureaucracy that has no direct equivalent in the UK, Ireland, or most of northern Europe. Worse, you are usually learning about it in the week before completion, which is a stressful place to start.
This guide is what we tell English-speaking buyers when they call us in a panic during conveyancing. It is straightforward — but the timing matters and the wrong answer can delay your move-in by days.
What a boletín eléctrico actually is
A boletín eléctrico is the document signed by an authorised electrical installer (“instalador autorizado”) that confirms a property’s electrical installation meets the Spanish low-voltage electrical regulation — the Reglamento Electrotécnico de Baja Tensión, REBT. The formal name is Certificado de Instalación Eléctrica de Baja Tensión — CIE for short. “Boletín” is the everyday word; “CIE” is what the supplier sometimes calls it. They are the same thing.
It is signed personally by an installer registered with the Junta de Andalucía, with their authorisation number on the document. Without that registration, the boletín is not valid.
When you really need one
Strictly speaking, you do not need one to complete the purchase — completion happens at the notary regardless. What you need it for is what comes next:
- Transferring the electricity supply contract into your name. Endesa, Iberdrola, Naturgy and the other suppliers will not transfer or open a contract on a property where the existing boletín is more than 20 years old, lost, or signed by an installer no longer registered.
- Reactivating a supply that has been disconnected for more than two years (very common on probate sales).
- Increasing the contracted potencia by more than 50% — for example, when adding AC, an EV charger, or an induction hob.
- Licensing a holiday let — most Andalusian municipalities require a current boletín as part of the VFT (vivienda con fines turísticos) registration.
In practice, the most common scenario is the first one. Within days of completion, you contact the supplier to put the contract in your name, and the supplier asks for the boletín. If you do not have one, the supply transfer stalls — and if the previous owner has already cancelled their contract, you can find yourself without electricity until the boletín is in place.
What happens if there is already a boletín on file
Sometimes the seller produces a boletín issued during a recent renovation. Sometimes there is a 30-year-old document the previous owner found in a drawer. Both technically count as “a boletín exists”, but the practical reality differs:
- A boletín issued in the last 5–10 years by a registered installer is usually accepted by the supplier without question.
- A boletín older than 20 years is increasingly rejected — suppliers are tightening up. If the property has not been worked on since, you may get away with it, but plan for a fresh one.
- No boletín on file — almost always means a fresh one is required before the contract transfers.
The practical answer: ask your lawyer or gestor what the existing boletín status is, before completion, not after. Most lawyers in Málaga handle a dozen of these a month and will know your specific situation in five minutes.
What is involved in getting one issued
The process for a typical apartment is:
- Inspection visit (60–90 minutes) — we walk the property, check the consumer unit, test the differentials, measure the earthing, check the bathroom zoning.
- Defect list, if any — written, with a clear quote for any required upgrades. Common items: outdated differential, missing pica de tierra, non-compliant kitchen circuit. Most flats need one or two small fixes.
- Upgrade work — usually a half-day to a day. Sometimes none, if the installation is already compliant.
- Boletín signed and registered — filed electronically with the Junta de Andalucía. You receive the stamped PDF and registration receipt.
For a fully compliant apartment with no defects, the entire process can be done in a single visit. For a property needing significant upgrades, allow a week.
Timing — when to start
The honest answer is: start before completion if you possibly can. If your conveyancing process is moving, ask your lawyer to confirm the boletín status with the seller well in advance. That gives you these options:
- Existing boletín valid? Nothing to do. Continue with the purchase.
- Existing boletín stale? Get a fresh one organised so the supply transfer can happen straight after completion.
- Significant upgrades needed? Negotiate with the seller — sometimes the seller pays, sometimes you split, sometimes the price drops to reflect it. All of this is much easier before signing.
If you are reading this after completion: call us, we will get to the property within a day or two, and have the boletín issued usually within the same week. The supply transfer can run in parallel.
What it does not solve
A boletín is a snapshot of the installation on the day it was issued. It is not:
- An ongoing safety guarantee — installations can degrade.
- A licence to ignore future REBT updates — major work later still needs documenting.
- A substitute for a survey on the rest of the property — plumbing, structure, damp, all separate concerns.
Who can sign one
Only an “instalador autorizado” — an installer registered with the Junta de Andalucía with a current authorisation number — can sign a valid boletín. Asking a handyman, an unregistered electrician, or a relative who works in trade in their home country does not produce a valid document, even if the work itself is fine. The signature and the registration are what give the boletín legal weight.
We are registered as authorised installers in the IBTE Especialista category, and we file every boletín we issue electronically with the Junta. The registration number and a copy of our installer card are available on request before any work starts.
What to do next
If you are mid-purchase, the action is simple: ask your lawyer for the current boletín status, and if there is any doubt, call us to schedule an inspection. The inspection is free and you walk away with a clear written assessment, with no obligation to proceed if you decide not to. That is enough to get you through completion without delay.
