Question 1

How much does it cost to rewire a whole house?

Accepted Answer

The cost to rewire a normal-sized house usually ranges between 70,000 SEK and 150,000 SEK after the ROT deduction. The price is determined by the size of the house, choice of materials (smart home features), and how accessible the conduits in the walls are.

Question 2

When must I hire an electrician for electrical installation?

Accepted Answer

All fixed installations – such as routing cables, installing new outlets, replacing the electrical panel, or laying heating cables – must by law be carried out by a registered electrical installation company. As a private individual, you are only allowed to perform simple tasks like changing a lightbulb or an existing switch cover (if you know how).

Question 3

Can I route the conduits myself before you arrive?

Accepted Answer

No, even laying empty conduits and junction boxes in the walls counts as electrical installation work. For us to take responsibility and provide a warranty on the system, we must perform the entire job.

Question 4

What should I do in case of an electrical emergency or power outage?

Accepted Answer

Safety first! If your RCD (jordfelsbrytare) trips repeatedly or you smell burning plastic, do not touch anything. We offer 24/7 emergency electrical services across Greater Stockholm with fast response times. Our certified electricians will secure your electrical system and fix the fault immediately to minimize the risk of fire or property damage.

Question 5

Which electrical installations provide the biggest savings on my energy bill?

Accepted Answer

The fastest ways to lower your energy costs are installing smart home controls (like Plejd) and upgrading to energy-efficient LED lighting. By scheduling your heating and lighting according to spot electricity prices, you can reduce energy waste by up to 20%. We handle all types of electrical work, from smart homes to safe EV charger installations.

Question 6

Can I use the ROT deduction and Green Tech deduction at the same time?

Accepted Answer

Yes! When we install an EV charger, we apply the Green Technology deduction, giving you a 50% discount on both materials and labor directly on the invoice. For other general electrical work in your home (like upgrading a fuse board), we deduct 30% of the labor cost via the ROT deduction. We handle all the paperwork with the Swedish Tax Agency for you.

Question 7

Why is it important to hire a certified electrical company?

Accepted Answer

Faulty wiring is one of the leading causes of house fires. Smista Elinstallation AB is a fully authorized electrical contractor approved by the Swedish National Electrical Safety Board (Elsäkerhetsverket) with over 30 years of combined experience. This guarantees a safe installation, valid warranties, and the official documentation often required by your insurance company.
