Electrical wiring for garages requires careful planning and the right permits. You need to report the electrical work to the Electrical Safety Authority and use an authorized electrician for safe installation. The cost varies between SEK 8 000-25 000 depending on the method and distance. This guide answers the most common questions about garage electrical installation and how to carry out the project safely.
What permits do I need to run electricity to the garage?
You must notify the Electrical Safety Authority of the electrical installation before starting the work. All electrical work involving new circuits or changes to the electrical panel requires notification and final inspection by an authorized electrician. Also contact your electricity network company for any connection notification.
Building permits are not normally required for electric garages, but some municipalities may have special rules. Check with your municipality before starting the project. Professional electricians are required by law for any installation that affects the electrical panel or involves new circuits.
Document the whole process with drawings and material specifications. This is needed for notification and facilitates future maintenance or expansion of your garage electricity supply.
How much does it cost to run electricity to the garage?
The cost of electrical cable garage installation varies between 8 000-25 000 SEK in total. Material costs include cables (50-150 SEK/meter), fuses (200-500 SEK), and possibly a new electrical panel (2 000-5 000 SEK). Labor costs for electricians range from SEK 600-800 per hour.
Digging costs will be added if you opt for underground cables, usually SEK 200-400 per meter depending on soil conditions. Connection fees to the electricity grid company can be between SEK 3 000-8 000 for new connections.
Comparison between installation methods:
- Underground cable: Most expensive initially but most discreet and safe
- Overhead line: Cheapest option but requires the right distance and height
- Installation through existing structures: Intermediate cost, depending on availability
What is the best method for bringing electricity to garages?
Underground cable is the most recommended method for garage electricity installation. It provides the safest and most discreet solution with no visual impact on the property. The cable is buried 70 cm deep with warning sand above for safety.
Overhead lines work well when the distance is short and you have the right height above the ground (at least 5.5 meters above roadways). This option is cost-effective but requires poles or brackets on buildings.
Installation through existing structures such as basements or attic spaces may be practical if these are available. The method requires less excavation work but may be limited by the design of the building.
Choose the method based on:
- Distance between main building and garage
- Land conditions and existing infrastructure
- Aesthetic preferences and future plans
- Budget and timeframe of the project
What do I need to consider when planning the electrical installation?
Calculate your power needs carefully before installation. Standard garages need a 16A fuse for basic needs like lighting and sockets. If you plan to charge electric vehicles or workshop, you need a more powerful installation with 25A or higher fuse.
Safety aspects are important in electrical work in garages. Place the switchboard at a suitable height (150-180 cm from the floor) and protected from moisture. Install earth leakage switches for all circuits and ensure that all sockets are suitable for the garage environment.
Plan for the future by running slightly stronger cable than is needed today. This will facilitate later upgrades without new installation. Document the installation with drawings and photographs for future reference.
Important factors to consider:
- Placement of sockets and lighting for optimal functionality
- Availability for service and maintenance
- Protection against weather and mechanical impact
- Possibility of future expansion or changes

Frequently Asked Questions
Can I dig for the underground cable myself or do electricians have to do everything?
You can dig the shaft for the underground cable yourself to save costs, but the wiring and all electrical connections must be carried out by a licensed electrician. Make sure that the digging depth is exactly 70 cm and that the trench is straight and free of stones that could damage the cable.
What happens if I do not report the electrical installation to the Electrical Safety Authority?
Failure to report electrical work is illegal and can result in fines of up to 50,000 SEK. In addition, your home insurance will not cover damage caused by incorrect installation and you will face problems when selling your house because the installation is not approved.
How long does it take from planning to finished electrical installation in the garage?
The whole process usually takes 2-4 weeks. Notification to the Electrical Safety Authority takes 1-2 weeks to process, the installation itself 1-2 days depending on the method, and final inspection takes place within a week of completion. Excavation work can extend the time in difficult ground conditions.
Do I need to upgrade my existing electrical panel for the garage electrical installation?
It depends on your current fuse box and available power. If you have an older fuse box or are already using full capacity, an upgrade is often needed. A modern electrician can assess this during the consultation and recommend the appropriate solution for your needs.
Can I install the electric vehicle charging station at the same time as the basic installation?
Yes, it's a good idea to plan for a charging station from the start, even if you don't have an electric vehicle yet. Install a stronger cable (at least 5x6 mm²) and 25A fuse to cope with future charging needs. This is much cheaper than upgrading later.
What should I do if there are problems with the electrical installation after completion?
Contact the electrician who carried out the work immediately - all authorized electricians have liability insurance and guarantee their work. Document the problem with photos and do not blow the fuses yourself. In case of acute problems such as sparks or smell of burning, turn off the main power and call 112.
Is there any difference in requirements for detached garages versus garages attached to the house?
Yes, detached garages are considered a separate building and often require their own electrical panel with an earth leakage switch. Garages connected to the house can often be connected directly from the main switchboard. However, both cases require notification to the Electrical Safety Authority and professional installation.
