Upgrading an old electrical panel means replacing outdated safety switches, cabinets and wiring with modern components that meet today's safety standards. An upgrade improves electrical safety, reduces the risk of electrical fires and ensures that your home can handle modern electrical loads. The process always requires a qualified electrician and can take between one and three days depending on the scope.
Why do you need to upgrade an old switchboard?
Old switchboards from the 1970s and earlier often lack modern safety features such as earth leakage breakers and have insufficient capacity for today's electricity consumption. The safety risks of outdated systems include increased risk of electrical fires, electric shocks and fuses not tripping on overload.
Signs that your switchboard needs upgrading include old screw plugs instead of safety switches, absence of earth leakage circuit breakers, rusty or corroded components, and frequently blowing fuses. Modern power centers also have better energy efficiency and can handle electric vehicle charging stations and other energy-intensive appliances.
Upgrading becomes necessary when you renovate, install new electricity-intensive appliances, or when insurance companies require modern security systems. The benefits of modern systems include improved electrical safety, the ability to handle higher electrical loads and easier troubleshooting in case of problems.
What is included in a power plant upgrade?
A complete electrical panel upgrade includes replacing electrical cabinets, installing new safety switches and RCDs, updating main wiring and connecting all circuits to the new system. The process starts with a safety inspection of existing electrical wiring and planning the new installation.
Minor updates may involve just replacing old fuses with safety switches in the existing electrical cabinet, while full renovations include a new electrical cabinet, all wiring and complete remodeling of the electrical system. Electricians also install the necessary ground fault circuit interrupters (GFCIs) to protect against electric shocks in wet areas.
The work includes labeling all circuits, installing surge protectors and ensuring that all connections meet current electrical standards. All components are thoroughly tested before the system is put into service to ensure safe operation.
How long does it take to upgrade an electricity exchange?
A standard switchboard upgrade usually takes 1-3 days depending on the scope of the work and the size of the house. Minor updates that only include replacing safety switches can be completed in a day, while full renovations with new wiring can take up to a week.
Factors affecting the working time include the availability of the switchboard, the need for new wiring, the number of circuits to be connected and any complications with the existing installation. Planning and material procurement usually takes place 1-2 weeks before installation.
During the installation process, electricity will be switched off for parts of the work, so you should prepare for temporary interruptions. Electricians work systematically to minimize disruptions and restore electricity as quickly as possible after each work step.
What is the cost of upgrading an electricity exchange?
The cost of an electrical panel upgrade varies between SEK 15 000-50 000 depending on the scope of the work and the size of the house. Price factors include the type of electrical cabinet, the number of circuits, the need for new wiring and the complexity of the existing installation.
A basic upgrade with a new electrical cabinet and safety switch usually costs SEK 15 000-25 000, while a complete renovation with new wiring can cost SEK 30 000-50 000 or more. Materials make up around 30-40% of the total cost, while labor costs and expertise make up the rest.
Professional installation ensures that the work is carried out to current safety standards and gives you guarantees on both materials and workmanship. Trying to save money by hiring unqualified staff can lead to safety risks and higher costs in the long run if problems occur.

Frequently asked questions
Can I continue to live in the house during the power plant upgrade?
Yes, you can stay at home during the upgrade. Electricity will be off for certain parts of the work, usually 2-6 hours at a time. Plan to use battery-powered devices and prepare to be unable to use stoves, refrigerators and other electrical appliances during these periods.
Do I need a building permit to upgrade my electrical panel?
No, building permits are not normally required for electrical panel upgrades. However, the work must be carried out by a qualified electrician and notified to the Electrical Safety Authority. Electricians usually handle this notification and ensure that all permits are in order.
What happens if electricians find problems with my existing wiring?
If electricians discover damaged or insufficient wiring during the upgrade, they will inform you immediately. You will then receive an estimate of the cost to fix the problems. In some cases, work may need to be paused until the wiring is replaced to ensure safety.
How do I prepare for the power plant upgrade?
Clear the area around the switchboard so that electricians have free access. Charge all electronic devices in advance and buy batteries for flashlights if necessary. Inform family members of planned power cuts and consider booking in sensitive appliances such as fridges and freezers elsewhere if the work will take several days.
Can I get financial support for power plant upgrades?
Yes, there are several possibilities for financial support. The ROT deduction provides a 30% deduction on the cost of work up to SEK 50,000 per year. Some municipalities also offer energy or safety grants for older properties. Contact your municipality to find out what support is available.
What guarantees do I get on the new switchboard?
Professional electricians usually provide a 2-5 year warranty on workmanship and installation. Components such as electrical cabinets and safety switches have a manufacturer's warranty of 10-25 years. Make sure to get written warranties and keep all receipts and certificates for future reference.
How often should I check my new switchboard after the upgrade?
Do a visual check every month to make sure no components look damaged or smell burnt. Test the RCDs every three months by pressing the test button. Every five years, have a professional electrician carry out an inspection to ensure that everything is working optimally.
