Electricians in Spain - Qualifications, Certificates and Common Jobs Explained
Electrical work in Spain - where the certificate matters as much as the job itself
Every significant piece of electrical work carried out in Spain by a registered electrician must be accompanied by a Certificado de Instalacion Electrica. Without it, the work has no legal standing, your insurer can refuse any claim linked to that installation, and a buyer's solicitor will flag it immediately when you come to sell. This is not a formality - it is the document that proves the work was done correctly and legally.
Finding a registered electrician on the Costa del Sol is straightforward once you know what to look for. This guide covers everything expats need to know.
What registration must a Spanish electrician hold
Electricians in Spain must be registered as an Instalador Electrico Autorizado with the regional Consejeria de Industria. In Andalusia this is administered by the Junta de Andalucia. There are two main categories:
- Categoria Basica - authorised for standard domestic electrical installations including wiring, sockets, lighting circuits, and consumer unit replacement. Covers the majority of domestic work expats need.
- Categoria Especialista - authorised for more complex installations including three-phase systems and higher-power industrial or commercial work. Not required for most domestic Costa del Sol properties.
Ask for the electrician's Carnet de Instalador Electrico Autorizado before any work starts. Check the category and the expiry date. An expired registration is as useful as no registration at all.

What the Certificado de Instalacion Electrica covers
The certificate issued on completion of significant electrical work confirms that the installation was carried out by a registered professional to the correct Spanish standard. It should include the electrician's registration number, the address of the property, a description of the work, the date of completion, and the electrician's signature and stamp.
Keep this document with your property papers. You will need it for insurance purposes, when applying for or upgrading your electricity supply contract with your provider, and when you sell the property.
