What Licences Should a Spanish Electrician Have and How to Check Them
Hiring an unqualified electrician in Spain is a bigger risk than most expats realise
Electrical work carried out by an unregistered electrician in Spain is not just substandard, it is illegal. It voids your home insurance, creates liability if something goes wrong, and produces no certificate, which means no proof that the work was done correctly. When you come to sell the property, a buyer's solicitor will flag it immediately.
The problem is that on the Costa del Sol, plenty of people offer electrical work without holding the correct qualifications. Some are handymen who have picked up basic skills. Some are tradespeople qualified in another country whose credentials do not automatically transfer to Spain. Knowing what to ask for, and how to check it, is the only reliable protection.
The qualification every Spanish electrician must hold
In Spain, anyone carrying out electrical installation work on a property must be registered as an Instalador ElĂ©ctrico Autorizado with the regional industrial authority. In Andalusia, this is administered by the Junta de AndalucĂa through the ConsejerĂa de Industria, EnergĂa y Minas.
There are two categories of registration, and the difference matters depending on the work you need done:
- CategorĂa Básica (Category B) — authorised to carry out standard low-voltage domestic electrical installations. Covers the majority of household electrical work including wiring, sockets, lighting, and consumer unit replacement.
- CategorĂa Especialista (Category E) — authorised for more complex installations including three-phase systems, installations above certain power thresholds, and specialist industrial or commercial work. For most domestic expat properties, a Category B electrician is sufficient.
Ask any electrician you are considering hiring which category they hold. A registered electrician will tell you immediately and without hesitation. Someone who is not registered will change the subject.
What documents to ask for before hiring
Before agreeing to any electrical work, ask the electrician or their company to provide the following:
- Carnet de Instalador ElĂ©ctrico Autorizado - their registration card issued by the Junta de AndalucĂa. This shows their registration category, registration number, and expiry date. Check the expiry date, registrations require periodic renewal and an expired card means they are no longer authorised.
- Company NIF - if they operate as a business rather than as an individual autĂłnomo, ask for the company NIF and confirm they are registered with the Agencia Tributaria. Any legitimate electrical business will provide this without question.
- Seguro de Responsabilidad Civil - liability insurance certificate. Ask for the policy number and check the expiry date. If the policy has lapsed, they are operating without cover and any damage to your property during the work is your problem, not theirs.
How to verify an electrician's registration independently
Taking a document at face value is reasonable for most situations. For larger or more complex jobs, independent verification is worth the small effort involved.
In Andalusia, you can verify an electrician's registration by contacting the Junta de AndalucĂa's ConsejerĂa de Industria directly. Their offices are present in each provincial capital including Málaga. You can also use their online services portal at juntadeandalucia.es to search for registered installers by province.
Alternatively, contact the local Delegación Provincial de Industria in Málaga and ask them to confirm whether a specific registration number is current and valid. They are accustomed to this type of enquiry and will usually provide a straightforward answer.
What certificate you should receive after the work is done
Once significant electrical work is completed by a registered electrician, they are legally required to issue a Certificado de InstalaciĂłn ElĂ©ctrica. This document is issued through the ConsejerĂa de Industria and confirms that the work has been carried out to the correct standard by a qualified professional.
The certificate should include:
- The electrician's registration number and category
- The address of the property where work was carried out
- A description of the work completed
- The date of completion
- The electrician's signature and stamp
Keep this certificate with your property documents. You will need it for insurance purposes, when applying for or renewing your electricity supply contract with your provider, and when you sell the property. A buyer's solicitor will ask for it as part of their due diligence.
What the certificate does not cover
The Certificado de Instalación Eléctrica certifies the specific work described in it. It does not certify the entire electrical installation of a property unless a full rewire was carried out. If you are buying a property and want assurance about the overall state of the electrical installation, commission an independent electrical survey from a registered electrician before exchanging contracts.
Older properties on the Costa del Sol frequently have installations that predate current regulations. A certificate for a new consumer unit does not mean the rest of the wiring is compliant. Ask specifically whether the full installation has been inspected and what its current condition is.
British electricians working in Spain
Some expats assume that a British electrician living on the Costa del Sol is a safe choice because they speak English and understand UK standards. This is not always the case. UK electrical qualifications do not automatically transfer to Spain. A British electrician working in Spain must still hold Spanish registration as an Instalador Eléctrico Autorizado to carry out work legally.
There are British electricians on the Costa del Sol who have taken the steps to become properly registered in Spain. There are others who have not. Ask the same questions you would ask any electrician and check the same documents. Nationality is not a substitute for proper registration.
When to report an unregistered electrician
If you discover that electrical work on your property was carried out by an unregistered electrician, you can report this to the ConsejerĂa de Industria in Málaga. They take unregistered electrical work seriously because of the safety implications and will investigate complaints. Your local OMIC (Oficina Municipal de InformaciĂłn al Consumidor) can also advise on your rights and options.
Document everything before making a complaint. Photographs of the work, copies of any invoices or messages, and a written record of what was agreed and what was delivered will all strengthen your case.
