Choose a renovation company in Norway by giving several suppliers the same job description and checking experience and responsibility. Get a written agreement on price, progress and handover. When several trades are involved, know who coordinates the whole job.
What company do you need for renovation?
Choose based on the tasks to be completed and who will keep the work coordinated. Painting a room and rebuilding a bathroom need different planning.
Start with a list of the desired results. Write what should remain, be removed or be replaced. Separate necessary repairs from new wishes. It is then easier to prioritise if quotes exceed your budget.
When the job involves several trades, ask who organises them. One company may offer to combine work by a carpenter, painter, plumber and electrician. But have it explain which agreements you actually enter into.
SamfunnPrep explains complaints about tradespeople's services in a separate guide. This article helps before ordering: compare the delivery, allocate responsibility and plan a documented completion.
How do you find possible companies?
Search locally and look for experience from projects like yours. Use recommendations and quotation platforms to find candidates, then investigate them further.
Ask who did a previous job, its size and when it was finished. A photo of an attractive kitchen does not show how progress, budget and problems were handled. Ask about cooperation too.
On Mittanbud, you can describe renovation work and receive replies from businesses. The process was checked on 13 October 2026. Use profiles to investigate possible suppliers and ask for references from relevant work.
You can also contact companies directly. Give everyone the same description and drawings. If someone suggests a different solution, ask them to show the difference clearly. You then avoid comparing two prices for two completely different projects.
What should you check before a site visit?
Check the company's identity, relevant skills and who takes part in the job. Registration or an approval logo is only one part of the assessment.
Ask for the organisation number identifying the business. Compare the name on the quote with information from Brønnøysundregistrene's register search. Brønnøysundregistrene manages Norway's business registers. Also ask who will be your contact person during the work.
Sentral godkjenning, central approval, is a voluntary scheme at Direktoratet for byggkvalitet, abbreviated DiBK, Norway's building authority. It describes skills and procedures, among other things. See DiBK's explanation, checked on 13 October 2026. Check the correct business and approval area if the company refers to the scheme.
Electrical tasks need a separate check. Direktoratet for samfunnssikkerhet og beredskap, abbreviated DSB, Norway's civil protection authority, says you should check the electrical business in its register. Ask for the actual subcontractor's name. See DSB's advice on an approved electrician.
Ask about insurance and which damage it covers. Request documentation if needed. Do not assume that a general statement that a company is insured explains every risk in your project.
What do you clarify during the site visit?
Use the visit to clarify conditions that photos cannot explain. Ask the company to describe uncertain points and how they will be investigated.
A site visit, called befaring, is where the company looks at the job before a quote or work starts. Clarify beforehand whether the visit costs anything. Have drawings, previous documentation and your wish list available.
Walk through the rooms together. Ask whether water, electricity, ventilation and surfaces will be affected. Get an explanation of who protects floors, furniture and common areas. Also clarify access, keys, working hours and where waste will be stored.
If a wall or floor must be opened, ask for a plan for hidden conditions. The company cannot always know the condition before opening. Agree how findings are documented and who approves further work.
Does renovation need an application or other clarification?
Clarify application requirements based on the actual changes before ordering work. In rented housing or a housing association, also clarify who may approve the changes.
DiBK's overview of bathroom work distinguishes maintenance from more extensive work. As of 13 October 2026, complete refurbishment within one building unit, bruksenhet, or fire compartment may be exempt from an application. Relevant technical requirements still apply.
Work affecting several building units or fire compartments may require an application. A fire compartment is an area intended to limit the spread of fire. Ask the company to explain whether pipes, floors or walls change these divisions. Contact the municipality if uncertain.
An exemption from a municipal application is not the same as an agreement with your landlord or the board. Clarify necessary approvals and who obtains them. Include this in the plan before work begins.
How do you compare quotes for the whole project?
Compare the tasks and materials provided, who is responsible and what the price is based on. Ask for an explanation of excluded tasks and conditions.
Use a simple overview:
| Part of the quote | What you should be able to see |
|---|---|
| Tasks | Rooms, work components and desired result |
| Materials | Products, quality and who purchases them |
| Trades | Which companies do which parts? |
| Price | Pricing method, value added tax and possible extras |
| Progress | Start, milestones and expected completion date |
| Handover | Checks, documents and remaining work |
Merverdiavgift, often called mva., meaning value added tax, must be clear in the price you compare. Also ask about travel, transport, waste and protective covering. A price missing necessary parts cannot be directly compared with a complete delivery.
If you will buy products yourself, clarify delivery times and responsibility for incorrect orders. Ask for confirmation that the products fit the plan. Delayed materials may affect the sequence between several trades.
Agree on payment and changes in writing
Create a payment plan linking payment to clear parts of the delivery. Agree on how additional work and changes are approved before they are carried out.
Forbrukerrådet, the Norwegian Consumer Council, recommends a written contract for tradespeople's work. Use the contract with the job description, drawings and quote. Make sure the documents do not say different things.
Example of a practical change procedure: the company sends a description of the finding, proposed solution, price and new schedule. You approve it or ask for an alternative in writing. This is an organisational example, not a statutory contract format.
Ask for notification if one trade is delayed and others must wait. Clarify who follows up subcontractors. If you have separate agreements with several companies, you need to know who is responsible for cooperation between them.
What do you do at completion?
Go through the project with your contact person and note departures from the agreement. Ask for the agreed documentation and a clear plan for remaining points.
Take photos and write who will correct each point. Distinguish a new wish from a fault in ordered work. Keep the contract, changes, invoices and product information together.
Ask for explanations of maintenance and the use of new installations. Find out which documents come from each trade. You can then show what was done and by which company later.
Use SamfunnPrep's tools for practical tasks as a starting point for organisation. A contact list, budget and document folder make future work in the home easier.
