Electrical installations for shops and offices in Seville, Spain

Electrical contractor in Seville for shops and offices: from the works to the licence

Opening a business in Spain requires the electrical installation to be finished, legalised and documented before you apply for the licence. We do both: the installation of the shop or office, from the fuse board to the last socket, and the electrical documents you will need for the responsible declaration (declaración responsable) or the municipal licence. We work for shops, offices, practices, clinics, academies, beauty centres and franchises.

If the premises are already trading and you need more power, extra workstations, new lighting or an inspection, we do that too, organising the work so you do not have to close.

Opening a business in Seville as a foreign company or entrepreneur

International companies and foreign entrepreneurs often meet a system that works differently from home. Three ideas help:

• Licence and electrics go together. Law 12/2012 allowed many shops to replace the prior licence with a responsible declaration, but the electrical documents remain essential. Without the boletín, the file is incomplete.
• The installer signs, not the engineer alone. The boletín is signed by a registered installer company with the Junta de Andalucía. When the premises need an engineer’s project, we coordinate with the engineer.
• The distributor needs the same paper. To connect or extend the supply, e-distribución asks for the boletín too. Getting it right once saves weeks.

What the electrical installation of the premises includes

• Main board and sub-boards, with protection split by zones and selectivity, so a fault in one circuit does not leave the whole business in the dark. See also fuse board replacement.
• Separate circuits for lighting, sockets, air conditioning, shop window, sign and special equipment.
• General and commercial lighting: LED panels in offices, tracks and spotlights in shops, window and counter lighting.
• Emergency and signage lighting for exits and escape routes.
• Workstations with sockets, data network and, if needed, a UPS for critical equipment.
• Air conditioning: lines for the air conditioning units and extractors.
• Earthing measured and documented.
• Documents: technical design report or project, installation certificate registered with the Junta de Andalucía and support during the initial inspection when it applies.

Premises open to the public: what ITC-BT-28 requires

If your premises receive the public, they are classed as premises open to the public (local de pública concurrencia) and the installation follows ITC-BT-28 of the Low Voltage Electrotechnical Regulation. In practice this means:

• Emergency and signage lighting is compulsory and must work even if the supply fails.
• Halogen-free cables, with low smoke emission in a fire.
• Distribution of circuits so that a fault does not leave whole areas open to the public without light.
• Initial inspection by an authorised control body (OCA) in the cases set by ITC-BT-05, and then periodic inspections every 5 years.

In addition, ITC-BT-04 determines whether the installation needs a project signed by a qualified engineer or whether a technical design report is enough, depending on the power and the type of premises. We assess it on the first visit so there are no surprises when you apply for the licence.

Electrical documents for the opening licence

For your premises to open, the electrical part of the file needs, depending on the case:

1. Electrical installation certificate (boletín), issued by the installer company and registered with the industry department of the Junta de Andalucía. We explain it in our page on the electrical certificate (boletín).
2. Technical design report or electrical project, depending on power and use.
3. Initial inspection certificate from the control body when the premises require it.
4. New connection or extension of the supply with the distributor, which also needs the boletín.

If the premises have an old installation without documents, or the previous business left it out of compliance, it has to be upgraded and legalised first.

Lighting for shops, offices and clinics

Light sells in a shop and tires or rests the eyes in an office. We design the lighting on technical criteria:

• Offices and workstations. Lighting levels suited to the task according to standard UNE-EN 12464-1 on lighting of workplaces, without glare on screens.
• Shops and windows. Tracks with adjustable spotlights, accent light on the product and a shop window with programmed switching.
• Clinics and healthcare centres. Even light with good colour rendering in consulting rooms, and coordination with specialist installers when there are rooms with their own requirements, such as the operating theatres covered by ITC-BT-38.
• Efficiency. LED throughout the premises, detectors in toilets and storerooms and compliance with CTE HE 3 on the energy efficiency of lighting installations.

All our lighting work is under lighting.

How we work

1. Visit to the premises with the activity plans and the expected power of the equipment.
2. Technical proposal: board, circuits, lighting, emergency lighting and whether a project or a technical report is needed.
3. Fixed quote item by item, with a calendar coordinated with the works.
4. Installation, in phases if the business is open.
5. Checks and measurements: insulation, earthing and RCDs.
6. Legalisation: boletín, report or project, initial inspection if applicable and documents for the licence.
7. Maintenance afterwards, if you want it, with an annual check of emergency lighting and the board.

Guide prices in Seville

The full installation of premises is quoted by project, because it depends on the floor area, the power and the activity. Other rates are on our prices page.

Shops and offices in Seville

• City centre and old town. Premises in old buildings with installations that have been through several businesses, supply cables too small for today’s power and documents that cannot be found. Here the first step is a diagnosis and, almost always, a legalisation. More on the city centre.
• Nervión, Triana and Los Remedios. Local shops, professional practices and clinics on the ground floor of residential buildings, where coordinating the work with the comunidad (the homeowners’ association) matters. More on Nervión, Triana and Los Remedios.
• Offices in Cartuja and the business parks. Torre Sevilla and the buildings of the Cartuja Science and Technology Park (Sevilla TechPark) or the Torneo Business Park house offices that renew workstations, lighting and air conditioning. The technology park alone hosts 602 companies, 28 of them with international capital.
• Industrial estates in the metropolitan area. In Calonge, Store, Carretera Amarilla, PISA in Mairena del Aljarafe or La Isla in Dos Hermanas there are offices and showrooms next to warehouses, with three-phase supplies and space for chargers. More on Dos Hermanas and Mairena del Aljarafe.

EV charging in the car park

Non-residential buildings with more than 20 parking spaces had to have, from 1 January 2023, at least one charging station for every 40 spaces, and new office or commercial buildings with more than 10 spaces must leave conduits in 20 % of the spaces. If your business has parking for customers or staff, we install the chargers with load management, user cards and consumption control. See EV charger installation. All our services for businesses are under business and industry.
