Which group suits you
This page is useful if you want a charger for your electric car, want the electrical system checked or the fuse board replaced, or need an electrician for a housing cooperative, a commercial building or a boat.
| If you need | What to look at | Which group fits | What to check |
|---|---|---|---|
| A charger for your electric car at home | EV charging mentioned in the card description | Chargers, solar panels and smart homes | Whether the fuse board has to be upgraded before the charger can be fitted |
| Solar panels, a smart home or heating control | Solar panels, smart home or underfloor heating mentioned in the description | Chargers, solar panels and smart homes | What the firm supplies itself, and what you have to order from others |
| An electrical check, a new fuse board or fault-finding | Electrical checks, fuse boards or fault-finding mentioned in the description | Chargers, solar panels and smart homes, or Homes and businesses | Whether the site visit is free: some of the firms state that it is |
| An electrician for a housing cooperative or a commercial building | Housing cooperatives, commercial buildings or framework agreements mentioned in the description | New builds, housing cooperatives, commercial buildings and ships | Whether you get a regular contact person and a service agreement |
| Electrical systems on board a boat or ship | Ship installations and maritime electronics mentioned in the description | New builds, housing cooperatives, commercial buildings and ships | Which vessels and which equipment the firm takes |
Site visit first: how to order an electrician
- Two of the firms state a free site visit, and a third offers a free video site visit.
- Several have a contact form on their website; otherwise use the phone number in the card.
- Send a photo of the fuse board with your enquiry.
- Write what is to be connected: a charger, a heat pump, solar panels or new circuits.
An electrical job usually starts with someone looking at the installation. Two of the firms on this page state a free, no-obligation site visit (befaring), and a third lets you book a free video site visit (the firms' own websites, read on 6 October 2026). Several have a form where you enter your name, address and a message. With the rest, you call.
The enquiry is easier to answer with three pieces of information: a photo of the fuse board, roughly when the installation was put in, and what you want done. If it is an EV charger, write where the car is parked and how far it is from there to the board. If it is solar panels or a smart home, it helps to know whether you want to control heating, lighting or charging.
The quote should come in writing and say what is included: labour, materials, any upgrade of the fuse board and the paperwork you get at the end. If you ask several firms for a quote on the same description, you can compare them line by line.
Registration and documentation: what you can check yourself
- Elvirksomhetsregisteret, kept by DSB, is open online: look up the firm name before you order.
- A logo on the firm's website is not the same as an entry in the register.
- Agree what documentation you will get when the installation is finished.
- One firm on this page states that it documents its work in Boligmappa.
The Norwegian Directorate for Civil Protection (DSB) keeps Elvirksomhetsregisteret, a register of businesses that work on electrical installations. It is at elvirksomhetsregisteret.dsb.no. The editorial team has not looked up the eleven firms there, so that is a check you do yourself.
Some of the firms themselves write that they are authorised or registered, and one shows the DSB logo on its website. That is the firm's own information. Several give their organisation number on the website, and that helps you recognise the right business when several firms have similar names.
The documentation is what you are left with afterwards. One of the firms in the first group states in its card that it files the documentation in Boligmappa, a digital folder for the home. Ask the others how they deliver it, and keep the papers: the next electrician will want to see them, and so will a buyer on the day the home is sold.
Office hours, on-call service and where in the city the firms are based
- The offices open between 07:00 and 09:00 on weekdays and close between 15:00 and 16:00.
- No card lists weekend hours, and two cards have no opening hours at all.
- Two firms state a phone number for urgent help outside office hours.
- Five firms have an address east of the centre, four to the south and two to the west.
The electrical firms keep early office hours. The cards in the directory show in October 2026 that they open between 07:00 and 09:00 on weekdays and close between 15:00 and 16:00. Saturday and Sunday are not listed for any of them. If you call after 15:00, the office may be closed for the day.
Urgent help is documented for two firms, each in its own way. One states a number for urgent needs outside opening hours, the same number the office has otherwise. The other has a duty phone and writes that 24-hour service is included in the framework agreements it offers (both websites read on 6 October 2026). Without a framework agreement you should therefore ask whether the on-call service applies to you, and what a job in the evening costs.
The electrician comes to you, so the address mostly tells you where the firm has its base. Five of the eleven are east of the centre, among other places on Båtsmannsgata, Nedre Møllenberg gate and Bromstadvegen. Four are in the south, on Klæbuveien, Tempevegen, Utleirvegen and Hoeggvegen, and two in the west, on Mellomila and Cicilieveien. More electricians in Trondheim are listed in the category Construction & Installation Services, and other practical guides are under Services & practical.
Questions and answers

At two of the firms on this page it is, and a third offers a free video site visit, according to their own websites (read on 6 October 2026). Ask the others before you agree a time.
Seven of the eleven firms mention EV charging in the card or on their website. Start in the group Chargers, solar panels and smart homes, and say where the car is parked.
Two firms state a phone number for urgent help outside office hours. One of them ties its round-the-clock service to framework agreements, so ask whether it applies to private customers.

Look in the group New builds, housing cooperatives, commercial buildings and ships. One firm there states special agreements for housing cooperatives and jointly owned buildings, and a regular electrician to deal with.
