What should you do in a dispute with a tradesperson?

In brief

• Document the problem with photos, agreements, invoices and messages.
• Complain in writing as quickly as possible.
• Explain specifically what you believe is wrong and what you are demanding.
• Give the tradesperson a reasonable opportunity to inspect and correct the work.
• Withhold only the part of the payment that is necessary to secure your claim.
• Pay the part of the invoice that is not in dispute.
• Use an independent expert if the dispute is technical.
• Take the case further if you cannot find a solution.

What is the dispute about?

Before you send a complaint, you should define what you actually disagree about.

Common disputes between customers and tradespeople are about:

There may be several problems in the same project. Separate them and describe each point specifically.

Instead of writing "the job is bad", you should, for example, write:

The tiles on the wall by the shower have visible height differences. The joint between the floor and the wall has opened up, and water collects by the door instead of running towards the drain.

The more specific you are, the easier it is for the tradesperson, an expert or a complaints body to understand the case.

What you should do right away

When you discover a possible problem, you should not wait unnecessarily long.

1. Document what the work looks like

Take clear photos and video. Use both overview shots and close-ups.

The documentation should show:

Do not throw away damaged materials or remove parts of the work before the tradesperson has had an opportunity to inspect the problem, unless it is necessary to limit acute damage.

2. Gather all written documentation

Find:

If a lot was agreed verbally, you should write down your understanding of the conversations while you still remember them.

3. Make a simple timeline

A timeline makes the case considerably easier to understand.

The timeline should be short, factual and free of personal attacks.

Complain in writing

If the work has a fault or defect, you should complain in writing as soon as possible.

It is not always enough to mention the problem casually on the phone. A written complaint makes it possible to document when the tradesperson was notified, what the complaint concerned and what you demanded.

The complaint should include:

Send the complaint by email or through the platform where the job was agreed. Ask for written confirmation that it has been received.

Sample complaint

Subject: Complaint about work carried out at [address]

Hello,

I refer to the work you have carried out at [address], based on the quote or agreement dated [date].

I discovered the following on [date]:

I believe the work has not been carried out in accordance with the agreement or in a workmanlike manner. Photos and relevant documentation are attached.

I ask that you inspect the matter and give a written response by [date]. If there is a defect, I ask for a specific proposal for how and when it will be corrected.

Until the matter is resolved, I am withholding [amount] kr of the payment. The amount is calculated on the basis of what I currently believe is necessary to secure the claim. The part of the invoice that is not disputed will be paid as normal.

I would prefer to resolve the matter directly with you and therefore ask for a written response by the deadline.

Kind regards [Name] [Phone number] [Address]

Does the tradesperson have the right to correct the fault?

As a general rule, the tradesperson should be given the opportunity to inspect and correct a defect.

This is both a right and an obligation for the tradesperson. The correction should normally be carried out:

You should therefore be careful about hiring a new tradesperson immediately and then sending the bill to the original tradesperson.

If you do not give the original tradesperson a real opportunity to correct the work, it can weaken your claim.

There may still be exceptions. It may, for example, be necessary to use someone else if:

If that is the case, document why you believe it was not justifiable to wait.

Can you withhold payment?

In the case of a real defect or delay, you can normally withhold as much of the payment as is necessary to secure your claim.

That does not mean you can automatically withhold the entire invoice.

If the invoice is for 200,000 kr and correcting the fault will probably cost 25,000 kr, it will usually be difficult to justify withholding the entire invoice.

The amount must be assessed in each case. Take into account:

Pay the part of the invoice you do not disagree about. State in writing which amount is being withheld and why.

It is important to understand that withholding payment is not a fine or a punishment. The purpose is to secure a possible claim.

What if you disagree about the price?

Price disputes often arise because the parties have different understandings of what was included.

Start by clarifying what kind of price was agreed.

Fixed price

If you have agreed a fixed price for clearly defined work, the starting point is that the tradesperson is bound by that price.

Additional work can still be charged on top if it was actually ordered or there is another valid basis for the extra charge.

Price estimate

As a general rule, a price estimate cannot be exceeded significantly, and normally not by more than 15 percent, unless something else has been expressly agreed or the tradesperson is entitled to an additional charge, for example because of approved additional work.

Hourly work

For work charged by the hour, the invoice should make it possible to check:

Ask for an itemised invoice if it is not possible to understand how the amount was calculated.

Additional work

Additional work should be agreed in writing before it is carried out.

Clarify:

A message such as "we'll sort that out" is rarely a good enough change agreement.

What if the tradesperson is delayed?

There is normally a delay if the work is not finished by the agreed time, and this is not due to the customer or other circumstances the customer is responsible for.

Send a written notice and ask for:

In the event of a delay, the customer may, depending on the circumstances, be entitled to:

Daily penalties (dagmulkt) do not apply automatically to ordinary renovation jobs. It should be stated in the contract if the parties want such an arrangement.

What if the tradesperson has damaged your home?

If the tradesperson has caused damage, you must first make sure the damage does not get worse.

In the event of a water leak, electrical hazard or other acute incidents, you should contact the right professional straight away. Also notify your insurance company if the damage may be covered by your insurance.

Document:

Do not repair more than necessary before the other party has had an opportunity to see the damage, unless it is necessary to avoid a greater loss.

When should you use a surveyor or technical expert?

Many disputes cannot be resolved just by looking at photos. The parties may agree on what the work looks like but disagree on whether it has been carried out in a workmanlike manner.

In that case, it can make sense to use an independent expert.

This could be:

Ask for a written report that describes:

Clarify in advance who will pay for the assessment. It is not automatically the case that whoever "loses" the dispute always has to cover the entire cost. Liability for the cost can depend on the agreement, whether the inspection was necessary and how the case is decided.

Try to find a written solution

A practical solution is often better than a long complaints case.

Possible solutions include:

If you reach an agreement, the solution should be put in writing.

The agreement should state:

Do not accept the wording "the matter is finally settled" if there are still unresolved issues.

Example: How a dispute can develop

A customer pays 180,000 kr for a bathroom renovation. After completion, the customer discovers that water pools on the floor outside the shower area.

The customer takes photos, films the pooling water and sends a written complaint. The tradesperson believes the floor is within the requirements, while the customer believes the fall is wrong.

A sensible process could then be:

This process gives both parties the opportunity to explain themselves and reduces the risk of the case becoming simply one side's word against the other's.

What if the tradesperson sends the claim to debt collection?

If you disagree with a claim, you must dispute it in writing with both the tradesperson and any debt collection agency.

Explain:

A genuinely disputed claim should normally not be pursued through ordinary debt collection as if the claim were undisputed. Instead, the matter must be clarified, closed or brought before the courts.

That does not mean the debt automatically disappears. If it is later decided that the tradesperson was entitled to payment, interest and certain costs may still apply.

Do not ignore letters from the tradesperson, the debt collection agency, the Conciliation Board (forliksrådet) or a complaints body.

How to take the dispute further

If you cannot reach an agreement, there are several possible complaints routes.

1. Fikso's dispute process

If the job and the payment were handled through Fikso, and the dispute is covered by Fikso's current terms, the case can be submitted through the platform's dispute process.

Both parties may be asked to submit:

In a dispute, the disputed amount can be held back in the payment solution while the documentation is assessed. The part of the payment that is not in dispute can be processed separately.

Fikso's internal handling does not replace the parties' statutory rights or the option of taking the case further to a public complaints body or a court.

2. The Craftsman Complaints Board (Håndverkerklagenemnda)

The Craftsman Complaints Board may be relevant if the tradesperson is affiliated with a trade association covered by the scheme.

You must normally have complained in writing to the tradesperson first. Check the board's current terms and whether the business is covered before you submit the case.

3. The Norwegian Consumer Authority (Forbrukertilsynet)

If you, as a private individual, cannot reach an agreement with a business, the case can be sent to the Norwegian Consumer Authority for mediation.

You must first have tried to resolve the matter directly with the tradesperson. A processing fee is normally charged, and the rates can change.

The Consumer Authority tries to help the parties reach a voluntary solution.

4. The Consumer Disputes Commission (Forbrukerklageutvalget)

If mediation does not succeed, the case can in many cases be taken further to the Consumer Disputes Commission.

The Commission can handle disputes about, among other things, tradesperson services. Its decisions are binding unless the case is taken to court within the applicable deadline.

5. The Conciliation Board or the courts

The Conciliation Board is the first stage of the court system for many civil claims. Some cases can be handled in other ways or go on to the district court (tingretten).

Before you start legal proceedings, you should check:

For large amounts or complicated legal questions, you should consider legal advice.

Do not confuse the complaint deadline with the limitation period

This is a point many people overlook.

For work on real property, the outer complaint deadline is normally five years. You must still complain within a reasonable time after you discovered or should have discovered the defect.

At the same time, the monetary claim itself can become time-barred. The general limitation period is normally three years, and there are separate rules on when the period starts and on any additional period for hidden defects.

An ordinary written complaint to the tradesperson does not necessarily interrupt the limitation period. Bringing the case before an approved complaints scheme or a court can affect the limitation period.

If a deadline is approaching, you should not rely on informal negotiations alone. Find out how the limitation period can be interrupted, and consider legal assistance.

Check whether your insurance covers legal help

Many house, contents and home insurance policies include legal expenses cover.

The cover can help pay part of the costs of a lawyer and an expert in a dispute. There will normally be a deductible, and the insurance company may set conditions on which types of dispute are covered.

Contact your insurance company early and ask:

What you should not do

Even if you are frustrated, you should avoid actions that can make the dispute more difficult.

Do not handle the whole dispute over the phone

Phone calls can be used to find solutions, but always confirm the most important points in writing afterwards.

Do not withhold an arbitrary amount

The amount should be linked to the claim you are trying to secure.

Do not bring in a new tradesperson too early

The original tradesperson should usually be given the chance to inspect and correct the work.

Do not alter or destroy evidence

Take photos and give the other party an opportunity to see the work before it is removed.

Do not use threats or personal attacks

Keep the communication factual. Focus on the agreement, the work and the desired solution.

Do not publish undocumented accusations

Public posts can make the dispute worse and in some cases create new legal problems.

Do not ignore deadlines

Reply to letters and put the dates in your calendar.

Frequently asked questions

A factual process gives the best chance of a solution

A dispute with a tradesperson does not have to end in court. Many cases can be resolved if both parties get clear information, access to the documentation and a real opportunity to propose a solution.

As a customer, you are in a stronger position when you:

A secure payment solution can also reduce the risk of the money being paid out before a documented disagreement has been dealt with.

You should not have to pay as if everything is in order when there is a real defect. At the same time, the tradesperson should get a fair opportunity to inspect the matter, correct the work and present their documentation.

It is precisely this balance that provides the best basis for resolving the dispute in an orderly way.
